课时跟踪练33 Unit 3 Under the sea Ⅰ.阅读理解 Blue Planet Ⅱ's latest episode focuses on how plastic is having a devastating effect on the ocean and slowly poisoning our sea creatures.Researchers recently also found that sea creatures living in the deepest place on Earth，the Mariana Trench，have plastic in their stomachs.Indeed，the oceans are drowning in plastic.‎ Though it seems now that the world couldn't possibly function without plastics，plastics are a remarkably recent invention.The first plastic bags were introduced in the 1950s，the same decade that plastic packaging began gaining in popularity in the United States.This growth has happened so fast that science is still catching up with the change.Plastics pollution research，for instance，is still a very early science.‎ We put all these plastics into the environment and we still don't really know what the outcomes are going to be.What we do know，though，is disturbing.Ocean plastic is estimated to kill millions of marine animals every year.Nearly 700 species，including endangered ones，are known to have been affected by it.One in three leatherback turtles，which often mistake plastic bags for jellyfish，have been found with plastic in their bellies.Ninety percent of seabirds are now eating plastics on a regular basis.By 2050，that figure is expected to rise to 100 percent.‎ And it's not just wildlife that is threatened by the plastics in our seas.Humans are consuming plastics through the seafood we eat.I could understand why some people see ocean plastic as a disaster，worth mentioning in the same breath as climate change.But ocean plastic is not as complicated as climate change.There are no ocean trash deniers(否认者)，at least so far.To do something about it，we don't have to remake our planet energy system.‎ This is not a problem where we don't know what the solution is.We know how to pick up garbage.Anyone can do it.We know how to dispose (处理)of it.We know how to recycle.We can all start by thinking twice before we use single—use plastic products.Things that may ordinary，like using a reusable bottle or a reusable bag— when taken collectively，these choices really do make a difference.‎ ‎1．Why is plastics pollution research still a very early science?‎ - 8 -‎ A．The plastics pollution research is too difficult.‎ B．Plastics have produced less pollution than coal.‎ C．The world couldn't possibly function without plastics.‎ D．Plastics have gained in popularity too fast for science to catch up.‎ ‎2．How did the author support his opinion in Paragraph 3?‎ A．He presented statistics.‎ B．He cited quotes from leading experts.‎ C．He used examples from his own experience.‎ D．He used the strategy of comparison and contrast.‎ ‎3．What can we infer about climate change?‎ A．Climate change is caused by human activities.‎ B．Some people cast some doubts on climate change.‎ C．Climate change is less important than ocean pollution.‎ D．Ocean plastic is more complicated than climate change.‎ ‎4．What is the main idea of this passage?‎ A．Ocean plastic is a global issue.‎ B．The oceans become choked with plastic.‎ C．Blue Planet Ⅱ has left viewers heartbroken.‎ D．Plastics gain in popularity all over the world.‎ ‎【语篇解读】　塑料给海洋以及海洋中的生物造成了灾难性的影响，同时，也对人类的身体造成了影响。但是，塑料是可以降解的废物，人类只要注意自己的行为，并对塑料做无害化处理，这一污染问题是可以解决的。‎ ‎1．解析：细节理解题。根据第二段中的“The first plastic bags were introduced in the 1950s...Plastics pollution research，for instance，is still a very early science.”可知，第一批塑料袋出现于20世纪50年代，同一时期美国的塑料包装开始流行起来，这一发展是如此之快以至于科学仍在努力赶上这一变化，而对于塑料污染问题的研究仍然还是一个非常早期的科学。故选D项。‎ 答案：D ‎2．解析：推理判断题。根据本段信息可知，环境中的塑料每年杀死上百万只海洋动物，近700个物种，包括濒危物种在内，都受到了影响；90%的海鸟在吃塑料，而到2050年，这一数额会达到100%。由此可知，作者通过列举具体的数据来说明塑料的危害。故选A项。‎ 答案：A ‎3．解析：推理判断题。根据第四段中的“I could understand why some people see ocean plastic as a disaster，worth mentioning in the same breath as climate change.But ocean - 8 -‎ ‎ plastic is not as complicated as climate change.There are no ocean trash deniers，at least so far.”可知，有人视海洋中的塑料为灾难，认为可与气候变化问题相提并论。但是，海洋中的塑料并不像气候变化那样复杂。而且至少到目前为止，还没有海洋垃圾的否认者。也就是说，一些人对气候变化问题提出了质疑。故选B项。‎ 答案：B ‎4．解析：主旨大意题。本文介绍了塑料自从被人类发明以来，给人类带来便利的同时，也在污染着环境，尤其是海洋，目前很多物种因塑料污染而受到威胁。故选B项。‎ 答案：B Ⅱ.完形填空 Paul looked out of the window of the classroom and sighed.The driveway was still 1 and it was getting dark.His dad had said that he would 2 him up by 5：30，but it was almost seven and Paul hadn't heard a word from him.Paul 3 to do some of his reading homework. 4 ，he couldn't help thinking of his dad.He knew that his dad had a 5 and a life，but he couldn't 6 why he was always breaking his 7 ．‎ The next day at school，Paul didn't 8 his maths homework.Paul's teacher noticed his unusually 9 performance and asked him why.Paul didn't want to 10 him.He knew that if he started talking，a flood of 11 would pour out.He just wanted to be alone with his 12 ，so he sat there 13 ，not even looking at the teacher.“Well Paul，you can't have this thing eat you up.The sooner you get it off your 14 ，the sooner you can 15 ．”‎ As Paul walked home from school，he 16 the things the teacher had told him.Paul knew that he hadn't 17 himself recently.Maybe he stopped doing his work because he was looking for 18 from his father.He knew his teacher was 19 and decided to take the teacher's advice.When Paul got home，by a heartto heart talk with his dad，he 20 his feelings and finally understood his dad.‎ ‎1．A.dusty　　　　 B．noisy ‎ C．empty D．leafy ‎2．A.lift B．pick C．call D．put ‎3．A.tried B．seemed C．preferred D．pretended ‎4．A.Undoubtedly B．Honestly C．Thus D．However ‎5．A.job B．problem -
