四、阅读理解

Imagine a mass of floating waste is two times the size of the state of Texas.Texas has a land area of more than 678,000 square kilometres.So it might be difficult to imagine anything twice as big.

All together,this mass of waste flowing in the North Pacific Ocean is known as the Great Pacific Ocean Garbage Patch.It weighs about 3,500,000 tons.The waste includes bags,bottles and containers—plastic products of all kinds.

The eastern part of the Great Pacific Ocean Garbage Patch is about 1,600 kilometres west of California.The western part is west of the Hawaiian Islands and east of Japan.The area has been described as a kind of oceanic desert,with light winds and slow moving water currents.The water moves so slow that garbage from all over the world collects there.

In recent years,there have been growing concerns about the floating garbage and its effect on sea creatures and human health.Scientists say thousands of animals get trapped in the floating waste,resulting in death or injury.Even more die from a lack of food or water after swallowing pieces of plastic.The trash can also make animals feel full,diminishing their desire to eat or drink.

The floating garbage also can have harmful effects on people.There is an increased threat of infection of disease from polluted waste,and from eating fish that swallowed waste.Divers can also get trapped in the plastic.

Its existence first gained public attention in 1997.That was when racing boat captain and oceanographer Charles Moore and his crew sailed into the garbage while returning from a racing event.Several years earlier,another oceanographer learnt of the trash after a shipment of rubber duckies got lost at sea.Many of those toys are now part of the Great Pacific Ocean Garbage Patch.

1.The first paragraph is written to 　　　. 

A.introduce the topic of the text

B.inspire readers’ imagination

C.develop readers’ interest in Texas

D.talk about reasons for water pollution

答案:A

解析:推理判断题。根据第一段“Imagine a mass of floating waste is two times the size of the state of Texas.Texas has a land area of more than 678,000 square kilometres.So it might be difficult to imagine anything twice as big.”可知,作者拿得克萨斯州与大量的垃圾漂浮物进行比较从而引出本文话题。故选A项。

2.What does the underlined word “diminishing” in paragraph 4 mean?

A.Increasing.　　　　　　　B.Determining.

C.Weakening. D.Reserving.

答案:C

解析:词义猜测题。根据第四段倒数第二句“Even more die from a lack of food or water after swallowing pieces of plastic.”和下句中的“also”可知,垃圾也能使动物感到饱,减少它们吃东西的欲望。由此可知,画线词的意思是“减弱”。故选C项。

3.What can we infer about the floating garbage according to the text?

A.It gives rise to various diseases.

B.It does great harm to sea animals.

C.Causes of it still remain unknown.

D.Efforts to clear it have been made.

答案:B

解析:推理判断题。根据第四段第一句“In recent years,there have been growing concerns about the floating garbage and its effect on sea creatures and human health.”可知,漂浮垃圾会对海洋生物带来很大的危害。故选B项。

4.What is the author’s purpose in writing the text?

A.To warn people about dangers of diving in the ocean.

B.To explore the future of the North Pacific Ocean.

C.To give advice on how to recycle waste in the ocean.

D.To introduce the Great Pacific Ocean Garbage Patch.

答案:D

解析:作者意图题。本文通过介绍太平洋上漂浮的大量的塑料垃圾废物的情况,指出了它们对海洋中的生物以及人类的影响。故选D项。

五、七选五阅读理解

People have been curious about the oceans.Thousands of years ago,people started building boats to help them explore the watery parts of the world.Boats let people find new hunting grounds and discover new lands.　1　 The earliest boats were probably logs that people sat on as they floated downstream.Later,people made these logs more useful and comfortable by burning and scraping(刮) away the insides to make dugout boats and canoes.　2　 They tied logs together to make rafts.They wove reeds and branches to make tidy little boats that are still used in many parts of the world today.They sewed animal skins together and filled them with air—like a float you might use in a swimming pool.They used paddles,poles,and oars to help steer,or to more upstream.Boats like the Greek trireme were big and heavy and hard to steer.　3　 Soon people figured out how to use sails to catch the wind.Sailboats might only have one or two sails.But more sails meant more power,and fast tall ships could have dozens.People still use sailboats today,for cruising and racing.When steam engines were invented many years ago,boating became easier than ever.　4　 As engines got bigger and better,so did boats. 

Over the years,boats have been used for fishing,for fighting,for carrying goods,for fun—even for living on.　5　 

A.The world is a watery place.

B.It took hundreds of rowers to move a boat like that.

C.People experimented with different kinds of floating boats.

D.Boats have turned the world’s waterways into highways.

E.Until people learned to build boats,all this water was a barrier.

F.They carried people and goods farther than they’d ever gone before.

G.Ships with steam engines could sail long distances,even if there was no wind.

答案:1~5 FCBGD
