【題目】 The world uses about a thousand million (百萬) tons of water a day. Water is a human right and everyone should have their share. Yet more than 700 million people around the world have trouble getting clean, safe water.

Treating waste water is a good way to provide fresh water for us. And it also helps the environment by keeping waste out of rivers and oceans. 80% of waste water around the world is not treated at all, and it is running into oceans. But now we have got the technology to treat and reuse the waste water. While 75% of our planet is covered with water, only about 2% is freshwater- that comes from rivers, lakes, ice and snow. The rest, 98% of the water, is in seas and oceans. It is too salty to drink. Then desalination businesses come in. More than 19000 factories have been built around the world, mostly in coastal countries. They process (加工) more than 92 million tons of water every day. But the technology they use requires a lot of energy.

Scientists are working to create a less costly technology. They want to produce 20 times more clean water and make sure everyone has enough. But for now, the world still faces each day with not having enough water for everyone.

【1】How many people have trouble in getting clean water around the world?

A.Under 700 million.B.Over 700 million.C.About 92 million.

【2】Treating waste water helps the environment by________.

A.storing waste in ice and snow

B.letting waste run into oceans

C.keeping waste out of rivers and oceans

【3】What does the underlined word "desalination" in Paragraph 3 mean?

A.遠(yuǎn)洋運(yùn)輸B.食鹽銷售C.海水淡化

【4】At present, the technology to process water________.

A.needs much energyB.saves much moneyC.satisfies everyone

【5】What can we infer from the last paragraph?

A.Everyone has enough clean water.

B.The water problem is still serious.

C.Our planet is covered with water.

【答案】

【1】B

【2】C

【3】C

【4】A

【5】B

【解析】

“水是生命之源”，我們的生活離不開水。但地球上的水資源是有限的，全世界很多地方的人們?nèi)匀粵]有辦法獲得干凈、安全的水。現(xiàn)在我們有了一項(xiàng)新的技術(shù)，可以處理和再利用廢水，但它需要大量的能源，因此科學(xué)家們正在努力創(chuàng)造一種成本更低的技術(shù)。

【1】

細(xì)節(jié)理解題。根據(jù)第一段中“Yet more than 700 million people around the world have trouble getting clean, safe water.”可知，全世界有7億多人難以獲得干凈、安全的水。故選B。

【2】

細(xì)節(jié)理解題。根據(jù)第二段中“Treating waste water is a good way to provide fresh water for us. And it also helps the environment by keeping waste out of rivers and oceans.”可知，處理廢水是為我們提供淡水的好方法，它還有助于保護(hù)環(huán)境，使廢物遠(yuǎn)離河流和海洋。故選C。

【3】

詞義猜測題。根據(jù)單詞所在的上下文語境“The rest, 98% of the water, is in seas and oceans. It is too salty to drink. Then desalination businesses come in.”可知，地球上98%的水在海洋里，是咸水不能喝，然后下文“More than 19,000 factories have been built around the world”有很多工廠被建。由此可推測desalination的意思應(yīng)該是“海水淡化”，故選C。

【4】

細(xì)節(jié)理解題。根據(jù)第二段中“But the technology they use requires a lot of energy.”可知，現(xiàn)在處理海水的技術(shù)需要大量的能量。故選A。

【5】

推理判斷題。A：每個(gè)人都有足夠的干凈的水。B：水的問題仍然很嚴(yán)重。C：我們的星球被水覆蓋著。根據(jù)短文最后一句話“But for now, the world still faces each day with not having enough water for everyone.”可知，現(xiàn)在，世界每天仍然面臨著沒有足夠的水供每個(gè)人使用。由此可知現(xiàn)在水問題仍然非常嚴(yán)重，故選B。

【題目】 How much do you know about the North Pole(北極) and the South Pole? They are both places with very cold temperatures and few people live there. However, the North and South Poles are not much alike as people may imagine.

The North Pole has no land, only thick ice. Temperatures seldom go above 32°F, at which water turns into ice. Most of the time, it stays below zero. In winter temperatures are usually as low as-30°F.

Although conditions were very poor, people tried for many centuries to reach the North Pole. Over 100 years ago, two men, Robert Peary and Mathew Henson, were able to get to this environment full of troubles and difficulties. They reached the North Pole on March 8th, 1909. It was really a hard trip for them.

There are few things more dangerous than crossing the Arctic(北極圈) on foot. People who stayed there may face many problems: very cold temperatures, sudden storms, and even hunger. Most of the area is uninhabited, few people can live in such a difficult place.

People might think that with such low temperatures for most of the year, the ice would be thick and hard. However, this is not true in the Arctic. The movement of the ocean water under the ice may often cause many different changes on the surface. Sometimes the ice breaks into two opening lanes of water(水道) called "leads". Anyone who falls into a lead can be frozen to death in a few minutes.

【1】This passage is probably from ___________________.

A.a book review

B.a science book

C.a school report

D.a computer magazine

【2】According to the passage, what happened over 100 years ago ?

A.Two men succeeded in getting to the North Pole.

B.Temperatures in the North Pole went above 32°F.

C.The environment in the North Pole suddenly became worse.

D.The North Pole changed into thick ice because of the temperatures.

【3】What does the underlined word "uninhabited" mean in Chinese?

A.氣候惡劣的

B.充滿危險(xiǎn)的

C.困難重重的

D.無人居住的

【4】The reason for the ice to break into two opening lanes of water is that __________________.

A.the temperature suddenly drops

B.the water under the ice is frozen

C.the ocean water under the ice moves

D.the surface is covered with lots of ice

【5】What does this passage mainly talk about?

A.The thick ice in the North Pole

B.A difficult trip to the North Pole

C.The real situation in the North Pole

D.The differences between the North Pole and the South Pole

【題目】 Norm Pethrick, a 36-year-old man in Australia’s northern city Darwin, was praised on Thursday for jumping onto a crocodile’s back to save his wife Wendy at Litchfield National Park, a popular tourist spot southwest of Darwin, a local newspaper reported.

【題目】 A long time ago, Roman soldiers came to make war to Scotland. The Scots(蘇格蘭人) loved their country very much. They fought hard against their enemy(敵人), but there were too many of the Romans. It looked as if the Romans would win.

One night, the leader of Scots took his soldiers to the top of a hill. “We will rest here tonight, my men.” he said. “Tomorrow we will fight against the Romans again.

【題目】 How do you deal with plastic bags from the supermarket? Throw them away or recycle them? How about eating them?

The bags are no harmful to the environment. Humans and animals can safely eat them. Indian company EnviGreen has made a bag with natural material. It looks and feels just like plastic, but can break down （分解）easily.

Ashwath Hedge who set up the EnviGreen company spent four years doing experiments with 12 natural material. They include potato, corn, vegetable oil and banana. He made the material into liquid and used the liquid to make the bag.

Although the EnviGreen bag is more expensive than a common plastic bag, but it has many advantages. According to the Wall Street Journal, it takes 1, 000 years for common plastic bags to break down. But an EnviGreen bag can naturally break down in less than 180 days. It also breaks down in less than a day in water, and in less than a minute in boiling water. Hedge was happy to show it in his interview with The Better India. In the interview, he put an EnviGreen bag in water and ate it with a smile.

There are more than 15, 000 tons of plastic waste every day. But only 9, 000 tons are processed. In China, 3 billion plastic bags are used every day. Maybe the EnviGreen hag could be a solution to the world problem of plastic pollution.

【1】According to paragraph 2, we can know the following EXCEPT ________.

A.the EnviGreen bag can break down easily

B.the EnviGreen bag is made from natural material

C.the EnviGreen bag can be eaten by humans and animals

D.the EnviGreen bag is a little harmful to the environment.

【2】Then main idea of the third paragraph is “_________”.

A.What Hedge think of the new bagB.How Hedge makes the EnviGreen bag

C.Who sets up the EnviGreen companyD.How long it takes Hedge to make the bag

【3】The underlined sentence in paragraph 4 shows that the EnviGreen bag _______.

A.is safe and can break down quicklyB.is useful although it is more expensive

C.looks and feels like a common plastic bagD.will be used more widely than a common bag

【4】The Envi Green bag breaks down fastest in _________.

A.hot airB.cold waterC.boiling waterD.natural air

【5】From the last paragraph, we can infer（推斷）_______.

A.all of India`s public waste is processed

B.India has the most plastic waste in the world

C.China produces more plastic waste than India

D.the Envi Green bag may help solve the problem of plastic pollution
