一、完形填空Do you often use plastic straws (塑料吸管) You probably use them to drink lots of things, such as soybean milk, cola or milk tea. Plastic straws are small 1 they are a big problem. They are made in 10 minutes, used in 20 2 and normally remain on the earth for over 100 years since they are hard to be 3 .But how do plastic straws get into the ocean Through human mistakes, they are often thrown away everywhere and all gutters (排水沟) in some areas lead to our ocean. 4 , plastic straws kill ocean life. Once a 5 was found bleeding because a 12-centimeter-long plastic straw was pushed into 6 nose. How terrible!In fact, around 500 million plastic straws are used every day in the US alone. If we didn't act now, there would be more plastic in the ocean than fish by 2050.Luckily, more and more people around the world have realized this problem. They begin to think about 7 plastic straws are necessary or not when drinking drinks.So what can we do right now to reduce plastic pollution The simplest way is to say “ 8 ” to single-use plastic, like straws. For example, next time if you go to a restaurant, make sure you order your drink without a straw. There are reusable straws instead.Coffee house chain Starbucks has started to 9 strawless cups and paper straws instead of plastic straws in almost 1, 000 stores in Shanghai and Shenzhen. And McDonald’s has 10 taken action to reduce the use of the plastic straws. It is hoped that more businesses and customers will work together to protect our environment.1．A．and B．but C．or D．so2．A．seconds B．hours C．minutes D．days3．A．cut down B．written down C．put down D．broken down4．A．For example B．Such as C．Even worse D．For one thing5．A．turtle B．monkey C．camel D．giraffe6．A．their B．his C．her D．its7．A．whether B．if C．why D．what8．A．sorry B．yes C．no D．hello9．A．replace B．afford C．offer D．give10．A．still B．also C．ever D．just二、阅读理解We are used to seeing plastic all around us.From bags to bottles and toothbrushes，plastic things fill our homes，schools，and offices.But what happens to these things after we use them In the United States，recycling centers received tons of plastic every day.Experts say that does not stop plastic trash from polluting the sea.Plastic can end up in the ocean if the wind blows it there or if people litter. “The ocean is getting worse everywhere，” says Charles Moore，an expert.In 1997，Moore traveled from Hawaii to California by sea.On the journey，he discovered a huge “island”in the Pacific Ocean.The “island” was mostly made of plastic trash and it was twice the size of Texas(德克萨斯州)．It became known as the Great Pacific Garbage Patch(垃圾堆)．Moore has been watching the “island” ever since he found it. “It's 100 times worse now than it was then，” he said.All this plastic in the ocean puts sea animals at risk.Animals can become tangled(使缠结)in plastic.They can also take pieces of plastic for food by mistake. “The plastic makes them feel full，but they're not getting any good from that，” says Jambeck，another expert. “They usually starve to death(饿死)．”The plastic problem doesn't just appear in the Pacific.Each year，more and more plastic ends up in all of Earth's oceans.If we continue with business as usual，the plastic in the sea will double by the year 2025. But there are things we can do to stop it.Jambeck suggests choosing reusable things and picking products with less packaging(外包装)．Moore says, “It's everybody's problem.” But it's one we can all help eliminate．1.

We can make a difference答案及解析一、完形填空【答案】1．B 2．C 3．D 4．C 5．A 6．D 7．A 8．C 9．C 10．B【解析】本文主要介绍了塑料吸管对环境的危害，以及如何减少塑料污染的建议。1．句意：塑料吸管虽然小，但却是个大问题。and和；but但是；or或者；so因此。“Plastic straws are small”与“they are a big problem”是转折关系，故选B。2．句意：它们的制作时间为10分钟，使用时间为20分钟，由于它们不易分解，通常会在地球上保存100多年。seconds秒；hours小时；minutes分钟；days天。根据常识可知，我们通常是在喝饮品时可以用到塑料，喝饮品也就差不多20分钟左右，故选C。3．句意：它们的制作时间为10分钟，使用时间为20分钟，由于它们不易分解，通常会在地球上保存100多年。cut down砍倒；written down写下；put down放下；broken down分解。根据“ normally remain on the earth for over 100 years”可知，不容易被分解所以会在地球上保留更长时间，故选D。4．句意：更糟的是，塑料吸管会杀死海洋生物。for example例如；such as例如；even worse更糟的是；for one thing首先。根据“plastic straws kill ocean life”可知，塑料吸管会杀死海洋生物，这是更糟糕的事，故选C。5．句意：有一次，一只海龟被发现流血，因为一根12厘米长的塑料吸管被塞进了它的鼻子。turtle乌龟；monkey猴子；camel骆驼；giraffe长颈鹿。前文讲到了塑料吸管对海洋生物的危害，所以此处举的例子应是生存在海洋中的动物，故选A。6．句意：有一次，一只海龟被发现流血，因为一根12厘米长的塑料吸管被塞进了它的鼻子。their他们的；his他的；her她的；its它的。此空指代前文提到的“turtle”，要用its作定语，故选D。7．句意：他们开始思考在喝酒的时候是否需要塑料吸管。whether是否；if是否；why为什么；what什么。固定搭配：whether…or not表示“是否”，故选A。8．句意：最简单的方法是对吸管等一次性塑料说“不”。sorry抱歉；yes是；no不；hello你好。根据“So what can we do right now to reduce plastic pollution”可知，对“一次性塑料吸管”说“不”才能保护环境，故选C。9．句意：咖啡连锁店星巴克已经开始在上海和深圳的近1000家门店提供无吸管杯和纸质吸管，而不是塑料吸管。replace取代；afford买得起；offer提供；give给。根据“Coffee house chain Starbucks has started to … strawless cups and paper straws”可知，此处指星巴克开始提供无吸管杯和纸质吸管，故选C。10．句意：麦当劳也采取行动减少塑料吸管的使用。still仍然；also也；ever曾经；just只。前文讲到星巴克减少使用塑料习惯的举动，而麦当劳也采取了相应的措施，故选B。二、阅读理解【答案】1.A 2.C 3.D 4.B 5.D【解析】1. A 细节理解题。根据文章第二段中的Experts say...or if people litter.可知专家说回收中心每天回收大量塑料并不能阻止塑料垃圾污染海洋。如果风一吹或者人们乱丢塑料就会到海洋里。所以此处第二段是告诉我们塑料垃圾是怎么到海洋里的。故选A。2. C 细节理解题。根据文章第三段可知大太平洋垃圾带的区域现在比以前糟糕100倍。故选C。3. D 细节理解题。根据文章第四段可知海洋动物会被塑料垃圾缠绕，或者误食这些垃圾后饿死。这些都是塑料垃圾给海洋动物带来的不利影响。故选D。4. B 词义猜测题。根据文章最后一段可知选B。5. D 标题归纳题。这篇文章主要介绍了塑料垃圾在海洋越积越多，并对海洋造成了巨大的污染。所以标题应该是海洋里的塑料污染。故选D。三、七选五【答案】1-5DAGBF逐题解析1. D前一句：He has always had a passion for food and cooking.后一句：This is where he learned much of what he knows today.this 指代一个地点。D 说：他在父母的餐厅里打工赚零花钱长大。→ 正好对应后面的 this is where（就是在那里）。2. A前一句：21 岁就因电视节目全球出名。A：除此之外，他还有一本超级畅销的烹饪书。→ 都是在讲他的成就，和后面 “这么年轻就取得这么多！” 衔接自然。3. G前一句：他想 “回馈” 烹饪行业。G：所以 2003 年他开了 Fifteen 餐厅，旨在培训年轻厨师。→ 正好是 “回馈” 的具体做法。后面又说：很多来工作的年轻人没好好上学或找不到工作，这是他们的第二次机会。→ 和 G 完全对应。4. B这一段讲：他关注学校食堂的食物。B：他对提供的垃圾食品数量感到震惊。→ 所以他才觉得需要改变（things needed to change），逻辑完美。5. F前一句：他想在人们家里也带来改变。F：他想向他们展示：做饭不仅有趣，还能帮家里省钱。→ “them” 指普通家庭，和 “people's homes” 对应。四、选词填空【参考答案】1.them 2.years 3.was left 4.were becoming 5.third 6.to save 7.As 8.patience 9.suddenly 10.more beautiful逐空解析1. them句意：它们中没有一个看起来很强壮。解析：of 是介词，后面用宾格；指代前面的 four tiny twigs，用 them。2. years句意：在这些年里，其中三棵因为意外和贫瘠的土壤死了。解析：over the years 是固定搭配：在这些年里；多年来。3. remained句意：只有一棵常青树留了下来。解析：前面说三棵死了，这里表示 “留下、存活”，用 remain，全文过去时 → remained。4. became句意：下部的树枝变得光秃秃。解析：become bare 变得光秃，过去式 → became。5. third句意：只有树的顶部三分之一还是绿的。解析：the top third 表示 “前三分之一”，three 变序数词 third。6. to save句意：去年夏天我尽最大努力去拯救它。解析：do one’s best to do sth. 尽最大努力做某事 → to save。7.
