What to Do During an Earthquake
As we all know, an earthquake is a kind of terrible disaster. So what should we do when an earthquake comes
When an earthquake starts, students in the classroom should get under the desks immediately and wait until the teacher tells them it is safe to come out. However, for those who are at home, get immediately under the table in the living room or kitchen. Don’t go anywhere near the window and don’t go out onto the balcony.
If you are in the street when an earthquake happens, don’t stand near buildings, fences or walls. Move quickly to a large open place to wait. Remember that standing under trees could also be dangerous.

Passage1 阅读理解
There has been a dramatic increase in the number of natural disasters over the past few years, and it is assumed that global warming and climate change could cause even more disasters in the future. Some of the world’s leading cities are facing disasters like floods and heat waves.
London
London’s flood defences are getting older. Since 1982, the Thames Barrier (水闸) has protected the city from the threat of flooding, but it was only designed to last until 2030 and close once every two or three years. About 26 years later, the barrier now closes five or six times a year and according to Environment Agency predictions, by 2050 the barrier will be closed on almost every tide if the problem is not addressed.
There are 26 underground stations, 400 schools, 16 hospitals, an airport and 80 billion worth of property in London’s flood risk area, so large scale flooding would be disastrous.
Paris
Over a six-week period in July and August 2003, more than 11, 400—mainly elderly people—died in France from dehydration (脱水) and extremely high body temperature in a deadly heat wave. Heat waves of similar intensity (强度) are expected every seven years by 2050, so what can be done to make sure such a disaster does not happen again
One solution is to have air-conditioners installed in elderly care homes. But this is considered a short-term solution, as the increase in demand for electricity also increases carbon emissions (排 放).
In Paris the local authorities are encouraging architects to design new types of buildings such
as the building “Flower Tower”, which uses a covering of bamboo to act as a natural air-conditioner.
Shanghai
Shanghai is one of the fastest growing cities on Earth. It has a population of 18 million and is only 4 meters above sea level. Sea levels are predicted to rise by 20 cm within the next century.
An estimated 250 ，000 people move to Shanghai every year in search of work, placing extra
demands on energy consumption. China relies heavily on coal-fired power stations, but these emissions increase temperatures and, in turn, warmer seas increase the risk of typhoons.
1 ．What problem should be settled now in London
A ．How to protect the city’s property.
B ．Where to build its flood defences.
C ．How to improve the function of the old flood defences.
D ．How to use the Thames Barrier to protect the city.
2 ．Which of the following measures CAN’T solve the heat wave disaster in Paris
A ．Putting up new types of buildings with a covering of bamboo.
B ．Having air-conditioners installed in elderly care homes.
C ．Encouraging architects to design new types of buildings
D ．Forbidding the city to build “Flower Tower” .
3 ．The purpose of the passage is ________.
A ．to tell us how to protect the big cities
B ．to warn us of the increasing natural disasters in big cities
C ．to explain what causes flood and heat waves
D ．to give advice on how to defend natural disasters
Passage2 阅读理解
It’s terrible and strange, but I don’t really remember much about the hurricane itself. It all happened so suddenly. I was sitting in my room with my cat, Smartie, on my lap, when the roof just flew off. I was so frightened that I just froze.
Mom cried to get out quickly, but it was already too late by then. The rain was coming down so hard and so fast. Our street turned into a river in seconds. We were going nowhere.
At first, I was pleased we could stay at home, but soon it got really tough. Without a roof, staying inside was too dangerous. We just had drinking water that was sent to us by helicopter, but it was never enough. It was August, so it was really, really hot and it smelled so bad everywhere! 1 just spent the days watching the boats going up and down the street and looking out for Smartie. He had disappeared the moment the storm hit.
Living in the open air, we became breakfast, lunch and dinner for the mosquitoes_But Mom said that whatever happens, we should always try to see the good side of things. It was difficult to stay positive, though. All we had left were the clothes on our backs. But as Mom kept on reminding us, we were all together and safe. Mom’s words made us feel better. I remember us all lying under the midnight sky and looking up at the stars. Because there were no lights, we could see the Big Dipper, and the Milky Way. It was amazing! Despite the disaster, moments like those gave us hope for the future.
Although it was only a few days before we were rescued, it felt like months. We were taken to another town in a faraway county. Thankfully, Smartie came home just in time. None of us
knew that we wouldn’t be back for quite a while then.
Now, one year has passed and I’m back home in New Orleans. Some families have yet to return, but many others have come back. Although we are surrounded by reminders of the disaster. we are working together to rebuild our homes and our lives. Now we have another chance to look up at the stars of New Orleans, their beauty inspiring us and giving us confidence to move on.
4 ．When did this hurricane hit the author’s hometown
A ．In September. B ．In August. C ．In July. D ．In Summer.
5．What does the underlined sentence “we became breakfast, lunch and dinner for the mosquitoes” mean
A ．We ate mosquitoes as our meals.
B ．There were too many mosquitoes.
C ．We were tired of those mosquitoes.
D ．We were bitten by mosquitoes constantly.
6 ．What can we learn about those families in that area
A ．Some families still didn’t return home.
B ．Most families came back home.
C ．Few families returned home.
D ．Only we came back home.
7 ．Who played the most important role in surviving this disaster
A ．The author himself. B ．The author’s mum.
C ．Smartie. D ．All the people stuck in the disaster

Passage3
阅读下面材料， 根据其内容和所给段落开头语续写两段， 使之构成一篇完整的短文。续写词
数应为 150 左右。
A serious earthquake can be a terrible experience, and it is easy to forget safety measures in disorder. Fortunately, most earthquake safety measures are common sense, but if you forget everything else, remember the following instructions: drop, cover, and hold on. Also, the most of earthquake deaths happen after the earthquake, so remember that the danger does not end when the shaking does! And it is wise to learn some simple safety tips to protect yourself or your family members.
Practise for an earthquake. You should do earthquake practice and teach your children about earthquake safety. Everyone in the family should do some earthquake practice often. It’s very important.
Be always ready before an earthquake. It’s necessary to prepare yourself and your family. All family members should know how to turn off gas, water and electricity and know useful telephone numbers (120, 110, 119, etc.)
There is a strong chance of short circuits and fire breakouts during an earthquake. If you are cooking when an earthquake happens, make sure you turn off electrical connections and gas immediately when an earthquake happens.
If you stay indoors during an earthquake, move away from unsupported areas: windows, large mirrors and so on. The purpose is to protect yourself from falling objects. Try to get under a doorway or another area of the building which is held up by strong beams. Stay under a table or desk only if it is very strong. Do not rush to lifts, because it is far safer to stay where you are.
Research has shown that most injuries happen when people inside buildings try to go out. Cover your head with your arms around it and curl into a ball, and wait for the shaking to stop.
Para 1.
If you stay outdoors during an earthquake, go to an area which is as open as possible.
Para 2.
After an earthquake, many buildings are less strong, although they appear safe.
注意：
1. 所续写短文的词数应为 150 左右；
2. 至少使用 5 个短文中标有下划线的关键词语；
3. 续写部分分为两段，每段的开头语已为你写好；
4. 续写完成后，请用下划线标出你所使用的关键词语。

1 ．C 2 ．D 3 ．B
【导语】这是一篇说明文。文章介绍了世界上正面临洪水和热浪等灾害的 3 个城市。
1．推理判断题。由 London 下中的“London’s flood defences are getting older. Since 1982, the Thames Barrier (水闸) has protected the city from the threat of flooding, but it was only designed to last until 2030 and close once every two or three years. (伦敦的防洪堤正在老化。自 1982 年 以来，泰晤士河水闸保护了该市免受洪水威胁，但其设计仅能持续到 2030 年，每两三年关 闭一次)”点明了伦敦危机暗伏的原因是防洪堤老化， 故推测出伦敦现在应该解决如何改善旧 防洪堤的功能的问题。故选 C 项。

(一个解决方案是在养老院安装空调)”和第三段“In Paris the local authorities are encouraging architects to design new types of buildings such as the building “Flower Tower”, which uses a covering of bamboo to act as a natural air-conditioner. (在巴黎， 当地政府鼓励建筑 师设计新型建筑， 例如“花塔”，它使用竹子覆盖物作为天然空调)”可知， 盖上一层竹子的新
型建筑、在养老院安装空调和鼓励建筑师设计新型建筑(如花塔) 都是解决巴黎的热浪灾难
的措施， D 项“禁止城市建造“花塔””错误。故选 D 项。
3．推理判断题。由第一段“There has been a dramatic increase in the number of natural disasters over the past few years, and it is assumed that global warming and climate change could cause even more disasters in the future. Some of the world’s leading cities are facing disasters like floods and heat waves. (过去几年， 自然灾害的数量急剧增加， 据推测， 全球变暖和气候变化 可能在未来造成更多的灾害。世界上一些主要城市正面临洪水和热浪等灾害)”和下文介绍的

鼓励下团结一致共建家园的故事。
4．细节理解题。根据文章第三段“It was August, so it was really,really hot and it smelled so bad everywhere! (当时是八月， 非常非常热， 到处是难闻的气味。) ”可知， 飓风发生的时间是
八月 August。故选 B 项。 5．词句猜测题。由前三段内容可知，飓风吹走了我们的房顶，那时正是八月，天气很热很 热并且到处是难闻的气味，可推测晚上有很多蚊子。再根据此句“Livingin the open air,we became breakfast,lunch and dinner for the mosquitoes. (住在露天的环境中， 我们成了蚊子们的 早餐、午餐和晚餐了。) ”可推断出他们被蚊子咬，故 D 项“We werebitten by mosquitoes constantly. (我们不停地被蚊子咬。) ”符合语境，故选 D 项。
6．推理判断题。根据文章最后一段“Now,one year has passed and I’m back home in New Orleans. Some families have yet to return, but many others have come back.Although we are surrounded by reminders of the disaster. we are working together to rebuild our homes and our lives. (现在，一年过去了，我回到了新奥尔良的家中。一些家庭还没有回来，但许多人已 经回来了。尽管我们周围充满了灾难的回忆，但我们正在共同努力重建我们的家园和生 活。) ”可知一些人还没有回到家乡。 A 项“Some families still didn’t return home.”符合题意， 故选 A 项。
7．推理判断题。根据文章第四段“But Mom said that whatever happens,we should always try to see the good side of things. It was difficult to stay positive,though.All we had left were the clothes on our backs. But as Mom kept on reminding us,we were all together and safe. Mom’s words made us feel better.I remember us all lying under the midnight sky and looking up at the stars. Because there were no lights,we could see the Big Dipper,and the Milky Way. It was amazing!
Despite the disaster, moments like those gave us hope for the future. (但是妈妈说，无论发生什 么事， 我们都应该看到事情好的一面。虽然我们只剩下身上的衣服了， 但要保持积极是很难 的。但正如妈妈不断提醒我们的， 我们都在一起很安全。妈妈的话让我们感觉好多了。我记 得躺在午夜的天空下仰望星空。因为没有灯光， 我们可以看到北斗七星和银河系。这是惊人 的！尽管发生了灾难，但这样的时刻给了我们对未来的希望。) ”可知，如果没有妈妈对我 们的安慰和鼓励就没有现在安全和乐观的我们。故选 B 项。
8 ．F 9 ．D 10 ．C 11 ．G 12 ．A
【导语】本文是说明文，介绍了一些帮助人们在洪水中生存的建议。
8．上文“Surviving a flood is a combination of preparation and appropriate action as soon as the disaster begins.” (要想躲过洪水，一开始就得做好准备工作和采取适当的行动。) 提到在洪 水中生存准备工作和行动的重要性， 下文给出了具体的建议， 则设空处应该是承上启下的句 子， F 项“这里有一些帮助你和家人在洪水中生存的建议”能够承上启下， 符合语意。故选 F 项。
9．下文“Pick several meeting spots in case you need to leave home, such as a friend’s home in a safe town or a shelter in your area.” (万一需要离开家，你得选几个见面的地点，比如去到在 安全的城镇的朋友家， 或是你所在区域的避难所。) 提到制定全家人集合的安全地点， 确保 全家人知道地点在哪以及去的路线。 D 项“和你的家人坐下来制定一个行动计划”符合本段内
容， 引出下文。其中“establish a plan”和小标题“Make a flood survival plan.”一致；“Sit down with your family”和下文“Make sure everyone in the family knows”内容一致。故选 D 项。 10．上句“When you’re not sure of the water depth, don’t risk it.” (当你不确定水的深度时，就 不要冒险。)指出不确定水深时不要贸然涉水，则设空处应该指出正确做法， C 项“如果你 必须涉水，就得携带一根棍子”指出必须涉水时正确做法是携带一根棍子，下文“Useit to measure the water’s depth and feel for stable (稳固的) ground.” (用棍子来测量水的深度， 并感 受地面是否稳定。) 则解释了棍子的作用， 其中 it 指代 C 项中的“a stick”。所以 C 项符合题 意。故选 C 项。
11．上文“Flooding information can be found on your local news or weather station’s TV channel or website.” (有关洪水的消息可以在当地新闻或气象台的电视频道或网站上找到。) 提到了解 有关洪水的消息的渠道， G 项“你应该收看天气预报， 关注天气变化”进一步告诉我们要关注 天气信息，了解变化。下文“Also, listen to local radio stations for regular updates.” (此外，定 期收听当地电台的最新消息。) 的“Also”承接 G 项内容， 指出了解洪水信息的另一做法。所 以 G 项符合题意。故选 G 项。
12．结合篇章结构可知， 设空处是第四个小标题， 是应对洪水的第四个建议。下文“Roadsand other paths may have been destroyed. Stay off bridges. The soil under usual routes will be soft and less able to support the weight of vehicles. Find other routes over high ground or wait for the
authorities to indicate which roads are safe.” (道路可能受损。远离桥梁。常规路线下的土壤会 变软， 难以支撑车辆的重量。我们应该在高地上寻找其他路线， 或者等待当局指示哪些道路 是安全的。) 介绍洪水中的路况隐患和如何选择安全路线， A 项“留意受灾区域”能够概括该 段内容， 下文“Roads and other paths may have been destroyed”与 A 项的“damaged areas”一致。 所以 A 项符合题意。故选 A 项。
13 ．B 14 ．C 15 ．D 16 ．B 17 ．A 18 ．A 19 ．C 20 ．B 21 ．C 22 ．A 23 ．D

Passage1
Dear Kate,
I’m writing to inform you a newcomer, of some tips on hurricane safety so that you can survive this common threat to a coastal city.
Knowing what to do matters when a hurricane strikes. Before a hurricane, make sure your property is protected. Close windows and bring indoors anything that could blow away. You should have sufficient food, water, medicine and batteries for emergency. During a hurricane, you’d better stay in the shelter, away from windows and listen to weather warning. Do not assume the storm has passed and go out even if the wind stops. Dangerous winds may return.
Yours Li Hua

Passage2
Dear readers,
I’m writing to tell you something about tsunamis and give you some advice on how to protect us when tsunamis break out.
Tsunamis are usually caused by strong earthquakes that happen in oceans. Great sea waves will be pushed towards shores with great speed. If tsunamis happen, people living near the shores will be in danger. The buildings will also be destroyed.
To protect ourselves from the natural disaster, here are some suggestions for you. First, when we are playing or living near the shore, it’s vital for us to be aware of the warning system so that we can be prepared for disasters. Second, if tsunamis happen, we must run towards high land as fast as possible. Holding tight to branches or driftwood, we can also save our lives.
I hope my advice will be helpful. I wish all of us can protect ourselves from dangers and live
a happy
life.
Yours, Li Hua

One possible version:
Para 1.
If you stay outdoors during an earthquake, go to an area which is as open as possible. Don’t move to buildings, electric poles and other objects which may fall during an earthquake and injure you. If you are driving, stop the car as soon as possible and stay in your car. Protect your head and stay low to the ground till the shaking ends and it is safe to move. If you are close to the sea, try to get as far away from the water as possible. Earthquakes can cause huge waves that can really harm the people nearby.
Para 2.
After an earthquake, many buildings are less strong, although they appear safe. If you stay indoors, move people from the building quickly and help disabled or injured people. Once outdoors, move well away from the building so that if it falls down, you will not be injured. Wait till public safety officials announce that it is safe to stay indoors. By planning ahead and keeping calm during an earthquake, you can greatly increase your chances of survival without injury.
【分析】这是一篇说明文。一次严重的地震是一次可怕的经历， 人们很容易忘记混乱的安全 措施。幸运的是， 大多数地震安全措施都是常识， 但如果你忘了其他的事情， 请记住以下指 示:蹲下，找掩护，抓住。文章主要介绍了一些有关地震安全的知识。

What to Do During an Earthquake
As we all know, an earthquake is a kind of terrible disaster. So what should we do when an earthquake comes
When an earthquake starts, students in the classroom should get under the desks immediately and wait until the teacher tells them it is safe to come out. However, for those who are at home, get immediately under the table in the living room or kitchen. Don’t go anywhere near the window and don’t go out onto the balcony.
If you are in the street when an earthquake happens, don’t stand near buildings, fences or walls. Move quickly to a large open place to wait. Remember that standing under trees could also be dangerous.

Passage1 阅读理解
There has been a dramatic increase in the number of natural disasters over the past few years, and it is assumed that global warming and climate change could cause even more disasters in the future. Some of the world’s leading cities are facing disasters like floods and heat waves.
London
London’s flood defences are getting older. Since 1982, the Thames Barrier (水闸) has protected the city from the threat of flooding, but it was only designed to last until 2030 and close once every two or three years. About 26 years later, the barrier now closes five or six times a year and according to Environment Agency predictions, by 2050 the barrier will be closed on almost every tide if the problem is not addressed.
There are 26 underground stations, 400 schools, 16 hospitals, an airport and 80 billion worth of property in London’s flood risk area, so large scale flooding would be disastrous.
Paris
Over a six-week period in July and August 2003, more than 11, 400—mainly elderly people—died in France from dehydration (脱水) and extremely high body temperature in a deadly heat wave. Heat waves of similar intensity (强度) are expected every seven years by 2050, so what can be done to make sure such a disaster does not happen again
One solution is to have air-conditioners installed in elderly care homes. But this is considered a short-term solution, as the increase in demand for electricity also increases carbon emissions (排 放).
In Paris the local authorities are encouraging architects to design new types of buildings such
as the building “Flower Tower”, which uses a covering of bamboo to act as a natural air-conditioner.
Shanghai
Shanghai is one of the fastest growing cities on Earth. It has a population of 18 million and is only 4 meters above sea level. Sea levels are predicted to rise by 20 cm within the next century.
An estimated 250 ，000 people move to Shanghai every year in search of work, placing extra
demands on energy consumption. China relies heavily on coal-fired power stations, but these emissions increase temperatures and, in turn, warmer seas increase the risk of typhoons.
1 ．What problem should be settled now in London
A ．How to protect the city’s property.
B ．Where to build its flood defences.
C ．How to improve the function of the old flood defences.
D ．How to use the Thames Barrier to protect the city.
2 ．Which of the following measures CAN’T solve the heat wave disaster in Paris
A ．Putting up new types of buildings with a covering of bamboo.
B ．Having air-conditioners installed in elderly care homes.
C ．Encouraging architects to design new types of buildings
D ．Forbidding the city to build “Flower Tower” .
3 ．The purpose of the passage is ________.
A ．to tell us how to protect the big cities
B ．to warn us of the increasing natural disasters in big cities
C ．to explain what causes flood and heat waves
D ．to give advice on how to defend natural disasters
Passage2 阅读理解
It’s terrible and strange, but I don’t really remember much about the hurricane itself. It all happened so suddenly. I was sitting in my room with my cat, Smartie, on my lap, when the roof just flew off. I was so frightened that I just froze.
Mom cried to get out quickly, but it was already too late by then. The rain was coming down so hard and so fast. Our street turned into a river in seconds. We were going nowhere.
At first, I was pleased we could stay at home, but soon it got really tough. Without a roof, staying inside was too dangerous. We just had drinking water that was sent to us by helicopter, but it was never enough. It was August, so it was really, really hot and it smelled so bad everywhere! 1 just spent the days watching the boats going up and down the street and looking out for Smartie. He had disappeared the moment the storm hit.
Living in the open air, we became breakfast, lunch and dinner for the mosquitoes_But Mom said that whatever happens, we should always try to see the good side of things. It was difficult to stay positive, though. All we had left were the clothes on our backs. But as Mom kept on reminding us, we were all together and safe. Mom’s words made us feel better. I remember us all lying under the midnight sky and looking up at the stars. Because there were no lights, we could see the Big Dipper, and the Milky Way. It was amazing! Despite the disaster, moments like those gave us hope for the future.
Although it was only a few days before we were rescued, it felt like months. We were taken to another town in a faraway county. Thankfully, Smartie came home just in time. None of us
knew that we wouldn’t be back for quite a while then.
Now, one year has passed and I’m back home in New Orleans. Some families have yet to return, but many others have come back. Although we are surrounded by reminders of the disaster. we are working together to rebuild our homes and our lives. Now we have another chance to look up at the stars of New Orleans, their beauty inspiring us and giving us confidence to move on.
4 ．When did this hurricane hit the author’s hometown
A ．In September. B ．In August. C ．In July. D ．In Summer.
5．What does the underlined sentence “we became breakfast, lunch and dinner for the mosquitoes” mean
A ．We ate mosquitoes as our meals.
B ．There were too many mosquitoes.
C ．We were tired of those mosquitoes.
D ．We were bitten by mosquitoes constantly.
6 ．What can we learn about those families in that area
A ．Some families still didn’t return home.
B ．Most families came back home.
C ．Few families returned home.
D ．Only we came back home.
7 ．Who played the most important role in surviving this disaster
A ．The author himself. B ．The author’s mum.
C ．Smartie. D ．All the people stuck in the disaster

阅读下面材料， 根据其内容和所给段落开头语续写两段， 使之构成一篇完整的短文。续写词
数应为 150 左右。
A serious earthquake can be a terrible experience, and it is easy to forget safety measures in disorder. Fortunately, most earthquake safety measures are common sense, but if you forget everything else, remember the following instructions: drop, cover, and hold on. Also, the most of earthquake deaths happen after the earthquake, so remember that the danger does not end when the shaking does! And it is wise to learn some simple safety tips to protect yourself or your family members.
Practise for an earthquake. You should do earthquake practice and teach your children about earthquake safety. Everyone in the family should do some earthquake practice often. It’s very important.
Be always ready before an earthquake. It’s necessary to prepare yourself and your family. All family members should know how to turn off gas, water and electricity and know useful telephone numbers (120, 110, 119, etc.)
There is a strong chance of short circuits and fire breakouts during an earthquake. If you are cooking when an earthquake happens, make sure you turn off electrical connections and gas immediately when an earthquake happens.
If you stay indoors during an earthquake, move away from unsupported areas: windows, large mirrors and so on. The purpose is to protect yourself from falling objects. Try to get under a doorway or another area of the building which is held up by strong beams. Stay under a table or desk only if it is very strong. Do not rush to lifts, because it is far safer to stay where you are.
Research has shown that most injuries happen when people inside buildings try to go out. Cover your head with your arms around it and curl into a ball, and wait for the shaking to stop.
Para 1.
If you stay outdoors during an earthquake, go to an area which is as open as possible.
Para 2.
After an earthquake, many buildings are less strong, although they appear safe.

【导语】这是一篇说明文。文章介绍了世界上正面临洪水和热浪等灾害的 3 个城市。
1．推理判断题。由 London 下中的“London’s flood defences are getting older. Since 1982, the Thames Barrier (水闸) has protected the city from the threat of flooding, but it was only designed to last until 2030 and close once every two or three years. (伦敦的防洪堤正在老化。自 1982 年 以来，泰晤士河水闸保护了该市免受洪水威胁，但其设计仅能持续到 2030 年，每两三年关 闭一次)”点明了伦敦危机暗伏的原因是防洪堤老化， 故推测出伦敦现在应该解决如何改善旧 防洪堤的功能的问题。故选 C 项。

(在巴黎， 当地政府鼓励建筑 师设计新型建筑， 例如“花塔”，它使用竹子覆盖物作为天然空调)”可知， 盖上一层竹子的新
型建筑、在养老院安装空调和鼓励建筑师设计新型建筑(如花塔) 都是解决巴黎的热浪灾难
的措施， D 项“禁止城市建造“花塔””错误。故选 D 项。
3．推理判断题。由第一段“There has been a dramatic increase in the number of natural disasters over the past few years, and it is assumed that global warming and climate change could cause even more disasters in the future. Some of the world’s leading cities are facing disasters like floods and heat waves. (过去几年， 自然灾害的数量急剧增加， 据推测， 全球变暖和气候变化 可能在未来造成更多的灾害。世界上一些主要城市正面临洪水和热浪等灾害)”和下文介绍的

八月 August。故选 B 项。 5．词句猜测题。由前三段内容可知，飓风吹走了我们的房顶，那时正是八月，天气很热很 热并且到处是难闻的气味，可推测晚上有很多蚊子。再根据此句“Livingin the open air,we became breakfast,lunch and dinner for the mosquitoes. (住在露天的环境中， 我们成了蚊子们的 早餐、午餐和晚餐了。) ”可推断出他们被蚊子咬，故 D 项“We werebitten by mosquitoes constantly. (我们不停地被蚊子咬。) ”符合语境，故选 D 项。
6．推理判断题。根据文章最后一段“Now,one year has passed and I’m back home in New Orleans. Some families have yet to return, but many others have come back.Although we are surrounded by reminders of the disaster. we are working together to rebuild our homes and our lives. (现在，一年过去了，我回到了新奥尔良的家中。一些家庭还没有回来，但许多人已 经回来了。尽管我们周围充满了灾难的回忆，但我们正在共同努力重建我们的家园和生 活。) ”可知一些人还没有回到家乡。 A 项“Some families still didn’t return home.”符合题意， 故选 A 项。
7．推理判断题。根据文章第四段“But Mom said that whatever happens,we should always try to see the good side of things. It was difficult to stay positive,though.All we had left were the clothes on our backs. But as Mom kept on reminding us,we were all together and safe. Mom’s words made us feel better.I remember us all lying under the midnight sky and looking up at the stars. Because there were no lights,we could see the Big Dipper,and the Milky Way. It was amazing!
Despite the disaster, moments like those gave us hope for the future. (但是妈妈说，无论发生什 么事， 我们都应该看到事情好的一面。虽然我们只剩下身上的衣服了， 但要保持积极是很难 的。但正如妈妈不断提醒我们的， 我们都在一起很安全。妈妈的话让我们感觉好多了。我记 得躺在午夜的天空下仰望星空。因为没有灯光， 我们可以看到北斗七星和银河系。这是惊人 的！尽管发生了灾难，但这样的时刻给了我们对未来的希望。) ”可知，如果没有妈妈对我 们的安慰和鼓励就没有现在安全和乐观的我们。故选 B 项。
8 ．F 9 ．D 10 ．C 11 ．G 12 ．A
【导语】本文是说明文，介绍了一些帮助人们在洪水中生存的建议。
8．上文“Surviving a flood is a combination of preparation and appropriate action as soon as the disaster begins.” (要想躲过洪水，一开始就得做好准备工作和采取适当的行动。) 提到在洪 水中生存准备工作和行动的重要性， 下文给出了具体的建议， 则设空处应该是承上启下的句 子， F 项“这里有一些帮助你和家人在洪水中生存的建议”能够承上启下， 符合语意。故选 F 项。
9．下文“Pick several meeting spots in case you need to leave home, such as a friend’s home in a safe town or a shelter in your area.” (万一需要离开家，你得选几个见面的地点，比如去到在 安全的城镇的朋友家， 或是你所在区域的避难所。) 提到制定全家人集合的安全地点， 确保 全家人知道地点在哪以及去的路线。 D 项“和你的家人坐下来制定一个行动计划”符合本段内
容， 引出下文。其中“establish a plan”和小标题“Make a flood survival plan.”一致；“Sit down with your family”和下文“Make sure everyone in the family knows”内容一致。故选 D 项。 10．上句“When you’re not sure of the water depth, don’t risk it.” (当你不确定水的深度时，就 不要冒险。)指出不确定水深时不要贸然涉水，则设空处应该指出正确做法， C 项“如果你 必须涉水，就得携带一根棍子”指出必须涉水时正确做法是携带一根棍子，下文“Useit to measure the water’s depth and feel for stable (稳固的) ground.” (用棍子来测量水的深度， 并感 受地面是否稳定。) 则解释了棍子的作用， 其中 it 指代 C 项中的“a stick”。所以 C 项符合题 意。故选 C 项。
11．上文“Flooding information can be found on your local news or weather station’s TV channel or website.” (有关洪水的消息可以在当地新闻或气象台的电视频道或网站上找到。) 提到了解 有关洪水的消息的渠道， G 项“你应该收看天气预报， 关注天气变化”进一步告诉我们要关注 天气信息，了解变化。下文“Also, listen to local radio stations for regular updates.” (此外，定 期收听当地电台的最新消息。) 的“Also”承接 G 项内容， 指出了解洪水信息的另一做法。所 以 G 项符合题意。故选 G 项。

authorities to indicate which roads are safe.” (道路可能受损。远离桥梁。常规路线下的土壤会 变软， 难以支撑车辆的重量。我们应该在高地上寻找其他路线， 或者等待当局指示哪些道路 是安全的。) 介绍洪水中的路况隐患和如何选择安全路线， A 项“留意受灾区域”能够概括该 段内容， 下文“Roads and other paths may have been destroyed”与 A 项的“damaged areas”一致。 所以 A 项符合题意。故选 A 项。
13 ．B 14 ．C 15 ．D 16 ．B 17 ．A 18 ．A 19 ．C 20 ．B 21 ．C 22 ．A 23 ．D

Passage1
Dear Kate,
I’m writing to inform you a newcomer, of some tips on hurricane safety so that you can survive this common threat to a coastal city.
Knowing what to do matters when a hurricane strikes. Before a hurricane, make sure your property is protected. Close windows and bring indoors anything that could blow away. You should have sufficient food, water, medicine and batteries for emergency. During a hurricane, you’d better stay in the shelter, away from windows and listen to weather warning. Do not assume the storm has passed and go out even if the wind stops. Dangerous winds may return.
Yours Li Hua

Passage2
Dear readers,
I’m writing to tell you something about tsunamis and give you some advice on how to protect us when tsunamis break out.
Tsunamis are usually caused by strong earthquakes that happen in oceans. Great sea waves will be pushed towards shores with great speed. If tsunamis happen, people living near the shores will be in danger. The buildings will also be destroyed.
To protect ourselves from the natural disaster, here are some suggestions for you. First, when we are playing or living near the shore, it’s vital for us to be aware of the warning system so that we can be prepared for disasters. Second, if tsunamis happen, we must run towards high land as fast as possible. Holding tight to branches or driftwood, we can also save our lives.
I hope my advice will be helpful. I wish all of us can protect ourselves from dangers and live
a happy
life.
Yours, Li Hua

One possible version:
Para 1.
If you stay outdoors during an earthquake, go to an area which is as open as possible. Don’t move to buildings, electric poles and other objects which may fall during an earthquake and injure you. If you are driving, stop the car as soon as possible and stay in your car. Protect your head and stay low to the ground till the shaking ends and it is safe to move. If you are close to the sea, try to get as far away from the water as possible. Earthquakes can cause huge waves that can really harm the people nearby.
Para 2.
After an earthquake, many buildings are less strong, although they appear safe. If you stay indoors, move people from the building quickly and help disabled or injured people. Once outdoors, move well away from the building so that if it falls down, you will not be injured. Wait till public safety officials announce that it is safe to stay indoors. By planning ahead and keeping calm during an earthquake, you can greatly increase your chances of survival without injury.
