A
Between Thailand and Vietnam tourists tend to ignore that there is an entire country to be discovered beyond the decaying temples.If you've never been to Cambodia before，it can be overwhelming to take it all in at once.We've put together a guide for you to make things easier.
Arrival at Cambodia
Most visitors arrive in Cambodia via Siem Reap International Airport，which is three miles from Angkor Wat and roughly five miles from the city of Siem Reap.You can take minibuses，buses，or domestic flights from Siem Reap to other country regions，such as Phnom Penh，Battambang，Kampot，and Sihanoukville.
To travel to Cambodia，tourists require a visa.Check the Cambodian Ministry of Tourism website for the latest information on policies before making travel arrangements.
Things to do in Cambodia
If you're thinking about a holiday to Cambodia，we have two recommendations for you：
Siem Reap
Siem Reap，a tiny village about five kilometres south of Angkor Wat，has grown into the fastest-growing settlement in Cambodia.When it comes to tourist attractions，Siem Reap is all about delicious cuisine，traditional cottages，and a number of fun activities that won't ruin your holiday.
Tonle Sap
Tonle Sap，Southeast Asia's largest freshwater lake，grows from 1，000 square miles to 6，200 square miles during the rainy season，from June to October.Over 300 species of freshwater fish breed in the flooded forests，and the lake supplies half of Cambodia's entire fish catch.A short drive north of Siem Reap，Tonle Sap is known for its floating villages，where entire populations depend on the lake for their survival.
Where to stay
As Cambodia's most popular gateway city for tourists，Siem Reap has a wide variety of accommodation options，from hostels to five-star hotels.Booking in advance is especially important if you plan to travel during the peak season of December and February.
Best time to visit
Visit Cambodia in the dry season，which lasts from the end of November to the beginning of April.The Angkor temples are far more pleasant to visit during the dry season when the weather is cooler.
【语篇解读】 本文是一篇应用文。文章是柬埔寨旅游指南。
1．Which of the following items is a must for foreigners before visiting Cambodia
A．A visa. B．An Airline ticket.
C．A travel permit. D．A travel brochure.
√
A [细节理解题。根据Arrival at Cambodia部分中的“To travel to Cambodia，tourists require a visa.”可知，游客需要签证才能去柬埔寨旅游。故选A。]
2．What is special about Tonle Sap
A．It's the largest freshwater lake in Asia.
B．It possesses rich fishing resources.
C．It's the fastest-growing settlement in Cambodia.
D．It is Cambodia's most popular gateway city.
√
B [细节理解题。根据Tonle Sap部分中的“Over 300 species of freshwater fish breed in the flooded forests，and the lake supplies half of Cambodia's entire fish catch.”可知，Tonle Sap的特殊之处在于它有非常丰富的渔业资源。故选B。]
3．If Jack is a food blogger particular about accommodation，he's likely to recommend ________．
A．Tonle Sap B．Angkor Wat
C．Phnom Penh D．Siem Reap
√
D [推理判断题。根据Siem Reap部分中的“Siem Reap is all about delicious cuisine，traditional cottages”和Where to stay 部分中的“Siem Reap has a wide variety of accomodation options，from hostels to five-star hotels.”可知，特别关注住宿的美食博主Jack可能会想去Siem Reap。故选D。]
B
Black rhinos (犀牛) have terrible eyesight.Even so，these large African animals can fight against hungry lions and hyenas(鬣狗).With big sword-like horns，their large and thick-skinned body plan has proved to be good enough to survive in a place full of huge predators (捕食性动物).But those protective features are no match for humans with guns.
Today，the species is seriously endangered largely due to illegal hunting.But the rhinos may have an unlikely partner against hunters: the red-billed oxpecker (牛椋鸟).The chatty，sociable birds often hang out on the backs of rhinos，feasting on the ticks (虱子) on their bodies.
“And actually，research has shown that the tick is the favourite diet of an oxpecker.And if they feed on ticks，that is a good thing，” said Plotz，a behavioural ecologist.He suspected that the rhinos put up with them because the oxpeckers make loud alarm calls whenever they see humans approach—giving the rhinos an early warning to flee.
To test whether the oxpeckers do，in fact，act as noisy lookouts，Plotz and his team placed radio transmitters (发送器) in the rhinos' horns.The researchers found that rhinos without oxpeckers detected an approaching human only 23 percent of the time，at an average distance of 27 metres.But when oxpeckers were present，the birds warned the rhinos 100 percent of the time.And they sensed the human 61 metres away on average.And the more oxpeckers on the scene，the greater the detection distance— which means the earlier the warning.
It makes sense because the more eyes you have on your back looking out for you，the more chance that you can pick up anything coming.What we think is going on，fundamentally，is that the rhino is listening to the alarm call.There can be no doubt of that.Listening to oxpeckers' alarm calls brings a really strong anti-human benefit.
Plotz thinks the oxpeckers may have gradually changed and developed their behaviour because it protects their convenient food source.And the more lookouts，the better in what seems like a win-win for both species: the birds thrive and the rhinos survive.
【语篇解读】 本文是一篇说明文。文章主要介绍了红嘴牛椋鸟和黑犀牛之间的双赢关系：红嘴牛椋鸟借助犀牛背上的虱子生存，而黑犀牛则利用红嘴牛椋鸟发出的警报声逃避人类的偷猎。
4．What can we learn about black rhinos
A．They have terrible survival skills.
B．They are almost dying out.
C．They mainly feast on ticks.
D．Their biggest threat is lions.
√
B [细节理解题。根据第二段中的“Today，the species is seriously endangered largely due to illegal hunting.”可知，由于人类的偷猎，黑犀牛正处于灭绝的境地。故选B。]
5．Why can black rhinos stand oxpeckers
A．They can sense danger with the help of the birds.
B．They can do nothing about the tiresome birds.
C．The birds are main food for black rhinos.
D．The birds help rid rhinos of the ticks on their bodies.
√
A [推理判断题。根据第三段中的“He suspected that the rhinos put up with them because the oxpeckers make loud alarm calls whenever they see humans approach—giving the rhinos an early warning to flee.”可知，黑犀牛之所以能够忍受红嘴牛椋鸟在它们背上啃食，就是因为这些鸟可以给黑犀牛放哨，让它们及时意识到人类的靠近，从而快速躲避。故选A。]
6．How does the author show oxpeckers' anti-human benefit
A．By giving an example.
B．By telling a story.
C．By listing some data.
D．By asking a question.
√
C [推理判断题。根据第四段中的“The researchers found that rhinos without oxpeckers detected an approaching human only 23 percent of the time，at an average distance of 27 metres.But when oxpeckers were present，the birds warned the rhinos 100 percent of the time.And they sensed the human 61 metres away on average.”所列举的一系列数字可知，作者是通过列举数字来介绍红嘴牛椋鸟的反人类盗猎作用的。故选C。]
7．What's the text mainly about
A．The reason for black rhinos' extinction.
B．Measures possible to protect black rhinos.
C．Some facts related to red-billed oxpeckers.
D．A win-win for black rhinos and oxpeckers.
√
D [主旨大意题。根据最后一段中的“And the more lookouts，the better in what seems like a win-win for both species: the birds thrive and the rhinos survive.”并结合全文内容可知，文章主要介绍了黑犀牛和红嘴牛椋鸟之间的双赢关系。故选D。]
Ⅳ．阅读七选五
The most important thing to keep in mind when deciding to serve another is that service expects no rewards.When you expect something in return，and are not serving out of the goodness of your heart，others will notice.Sure they'll thank you. 1 .
When you give from your heart，the real power of service comes into play.Serving is a great opportunity to strengthen your trust and respect for another，and for them to do the same for you.Not only do you feel great about helping out，but you build your relationship with them，and they will feel more willing to help you in the future. 2 .
However，why is service so rarely seen these days？ 3 Sure，living in this day and age does not leave us much time，and the last thing people want to do is more work.“I'm too busy，there's too much work，or I don't have the time” may run through your head when you hear the word “service”，but the truth is the benefits are worth the sacrifice.Gandhi once said that，“The best way to find yourself is to lose yourself in the service of others.” 4 Some ideas of places you can serve are volunteer centres，nursing homes，boys and girls clubs，and so on.You can serve people as long as you want to.
5 Although it does take some work，the benefits are more than worth the sacrifice.Not only do you feel better about making another's day a little less stressful，but you strengthen your relationship with them and they will be more willing to help you in the future.
A．It's a win-win situation.
B．Service is simple.
C．Overall，service and selflessly giving to others are very powerful and have many benefits.
D．And they will offer you worse service.
E．Service is a complex event.
F．The problem is，there's always an excuse not to serve.
G．But the service becomes more of a situation，“I'll do this for you if you do this for me.”
【语篇解读】 本文是一篇议论文。文章论述的主题是对他人的服务。在决定为他人服务时，最重要的是要记住，服务是没有回报的。总的来说，服务他人和无私奉献是非常强大的，有很多好处。
1．G [上文提到“当你期望得到回报，而不是出于好心去服务，别人会注意到的。当然他们会感谢你的。”承接上文，G项But the service becomes more of a situation，“I'll do this for you if you do this for me.”(但服务更像是这样一种情况，“如果你为我做这件事，我就会为你做这件事。”)切题。故选G。]
2．A [上文提到“你不仅对帮助别人感觉很好，而且你和他们建立了关系，他们将来会更愿意帮助你。”承接上文，A项It's a win-win situation.(这是一个双赢的局面。)是对上文的总结。故选A。]
3．F [上文提到“然而，为什么现在很少看到这种服务呢？”下文提到“当然，生活在这个时代，并没有留给我们太多的时间，人们最不愿意做的事情就是做更多的工作。”承接上下文，F项The problem is，there's always an excuse not to serve.(问题是，总是有借口不服务。)切题。故选F。]
4．B [上文提到“找到自我的最好方法就是在为他人服务的过程中迷失自我。”下文提到“你可以服务的地方有志愿者中心、养老院、男孩女孩俱乐部等等。只要你想，你就可以服务他人。”承接上下文，B项Service is simple.(服务很简单。)切题。故选B。]
5．C [下文提到“虽然这确实需要付出一些努力，但付出的代价是值得的。”承接下文，C项Overall，service and selflessly giving to others are very powerful and have many benefits.(总的来说，服务他人和无私奉献是非常强大的，有很多好处。)切题。故选C。]

Between Thailand and Vietnam tourists tend to ignore that there is an entire country to be discovered beyond the decaying temples.If you've never been to Cambodia before，it can be overwhelming to take it all in at once.We've put together a guide for you to make things easier.
Arrival at Cambodia
Most visitors arrive in Cambodia via Siem Reap International Airport，which is three miles from Angkor Wat and roughly five miles from the city of Siem Reap.You can take minibuses，buses，or domestic flights from Siem Reap to other country regions，such as Phnom Penh，Battambang，Kampot，and Sihanoukville.
To travel to Cambodia，tourists require a visa.Check the Cambodian Ministry of Tourism website for the latest information on policies before making travel arrangements.
Things to do in Cambodia
If you're thinking about a holiday to Cambodia，we have two recommendations for you：
Siem Reap
Siem Reap，a tiny village about five kilometres south of Angkor Wat，has grown into the fastest-growing settlement in Cambodia.When it comes to tourist attractions，Siem Reap is all about delicious cuisine，traditional cottages，and a number of fun activities that won't ruin your holiday.
Tonle Sap
Tonle Sap，Southeast Asia's largest freshwater lake，grows from 1，000 square miles to 6，200 square miles during the rainy season，from June to October.Over 300 species of freshwater fish breed in the flooded forests，and the lake supplies half of Cambodia's entire fish catch.A short drive north of Siem Reap，Tonle Sap is known for its floating villages，where entire populations depend on the lake for their survival.
Where to stay
As Cambodia's most popular gateway city for tourists，Siem Reap has a wide variety of accommodation options，from hostels to five-star hotels.Booking in advance is especially important if you plan to travel during the peak season of December and February.
Best time to visit
Visit Cambodia in the dry season，which lasts from the end of November to the beginning of April.The Angkor temples are far more pleasant to visit during the dry season when the weather is cooler.
1．Which of the following items is a must for foreigners before visiting Cambodia
A．A visa. B．An Airline ticket.
C．A travel permit. D．A travel brochure.
2．What is special about Tonle Sap
A．It's the largest freshwater lake in Asia.
B．It possesses rich fishing resources.
C．It's the fastest-growing settlement in Cambodia.
D．It is Cambodia's most popular gateway city.
3．If Jack is a food blogger particular about accommodation，he's likely to recommend ________．
A．Tonle Sap B．Angkor Wat
C．Phnom Penh D．Siem Reap
B
Black rhinos (犀牛) have terrible eyesight.Even so，these large African animals can fight against hungry lions and hyenas(鬣狗).With big sword-like horns，their large and thick-skinned body plan has proved to be good enough to survive in a place full of huge predators (捕食性动物).But those protective features are no match for humans with guns.
Today，the species is seriously endangered largely due to illegal hunting.But the rhinos may have an unlikely partner against hunters: the red-billed oxpecker (牛椋鸟).The chatty，sociable birds often hang out on the backs of rhinos，feasting on the ticks (虱子) on their bodies.
“And actually，research has shown that the tick is the favourite diet of an oxpecker.And if they feed on ticks，that is a good thing，” said Plotz，a behavioural ecologist.He suspected that the rhinos put up with them because the oxpeckers make loud alarm calls whenever they see humans approach—giving the rhinos an early warning to flee.
To test whether the oxpeckers do，in fact，act as noisy lookouts，Plotz and his team placed radio transmitters (发送器) in the rhinos' horns.The researchers found that rhinos without oxpeckers detected an approaching human only 23 percent of the time，at an average distance of 27 metres.But when oxpeckers were present，the birds warned the rhinos 100 percent of the time.And they sensed the human 61 metres away on average.And the more oxpeckers on the scene，the greater the detection distance— which means the earlier the warning.
It makes sense because the more eyes you have on your back looking out for you，the more chance that you can pick up anything coming.What we think is going on，fundamentally，is that the rhino is listening to the alarm call.There can be no doubt of that.Listening to oxpeckers' alarm calls brings a really strong anti-human benefit.
Plotz thinks the oxpeckers may have gradually changed and developed their behaviour because it protects their convenient food source.And the more lookouts，the better in what seems like a win-win for both species: the birds thrive and the rhinos survive.
4．What can we learn about black rhinos
A．They have terrible survival skills.
B．They are almost dying out.
C．They mainly feast on ticks.
D．Their biggest threat is lions.
5．Why can black rhinos stand oxpeckers
A．They can sense danger with the help of the birds.
B．They can do nothing about the tiresome birds.
C．The birds are main food for black rhinos.
D．The birds help rid rhinos of the ticks on their bodies.
6．How does the author show oxpeckers' anti-human benefit
A．By giving an example.
B．By telling a story.
C．By listing some data.
D．By asking a question.
7．What's the text mainly about
A．The reason for black rhinos' extinction.
B．Measures possible to protect black rhinos.
C．Some facts related to red-billed oxpeckers.
D．A win-win for black rhinos and oxpeckers.
Ⅳ.阅读七选五
The most important thing to keep in mind when deciding to serve another is that service expects no rewards.When you expect something in return，and are not serving out of the goodness of your heart，others will notice.Sure they'll thank you. 1
When you give from your heart，the real power of service comes into play.Serving is a great opportunity to strengthen your trust and respect for another，and for them to do the same for you.Not only do you feel great about helping out，but you build your relationship with them，and they will feel more willing to help you in the future. 2
However，why is service so rarely seen these days？ 3 Sure，living in this day and age does not leave us much time，and the last thing people want to do is more work.“I'm too busy，there's too much work，or I don't have the time” may run through your head when you hear the word “service”，but the truth is the benefits are worth the sacrifice.Gandhi once said that，“The best way to find yourself is to lose yourself in the service of others.” 4 Some ideas of places you can serve are volunteer centres，nursing homes，boys and girls clubs，and so on.You can serve people as long as you want to.
5 Although it does take some work，the benefits are more than worth the sacrifice.Not only do you feel better about making another's day a little less stressful，but you strengthen your relationship with them and they will be more willing to help you in the future.
A．It's a win-win situation.
B．Service is simple.
C．Overall，service and selflessly giving to others are very powerful and have many benefits.
D．And they will offer you worse service.
E．Service is a complex event.
F．The problem is，there's always an excuse not to serve.
G．But the service becomes more of a situation，“I'll do this for you if you do this for me.”
