About 97% of the world’s water is salty and is found in our oceans and seas. But, as we can’t drink sea water, how can it be important?
Every part of our seas and oceans contains an amazing number of animals and fish that live at different ocean depths. Most of the different species of animals and fish depend on simple plants for their food. These simple plants called algae (海藻) drift near the surface of the ocean and use sunlight to turn carbon dioxide and water into food and oxygen. In fact, algae produce over half of the oxygen people breathe. How important sea water is!
Each plant or animal in our seas and oceans is an important link in a food chain. The algae are eaten in large amounts by microscopic animals, which are in turn consumed by larger animals. These food chains are delicately balanced.
The bad news about the food chains in the oceans is that they are under threat because of man. People once thought that the oceans were so big that it didn’t matter if we dumped rubbish into them or caught huge quantities of fish and whales for food. But we now know this is not true and fish stocks in the oceans have started to drop.
Thankfully, the world is taking steps to protect the future of our oceans by introducing international agreements to protect marine habitats. Most countries have introduced fishing restrictions to protect fish stocks in the oceans and new techniques are being pioneered to cope with pollution. Finally, the importance of protecting oceans is being made known to more people. This is just the beginning of a long process to protect the oceans for our future. We depend on the oceans for fish which are an important part of the human diet. How important sea water is!
46. Which of the following is the proper order of the food chain?
A. small animals→algae→microscopic animals→large animals→man
B. algae→microscopic animals→large animals→larger animals→man
C. small animals→algae→large animals→microscopic animals→man
D. microscopic animals→algae→large animals →larger animals→man
47. People used to think that the rubbish thrown into the sea ________.
A. wouldn’t harm the fish in the sea B. would change the balance of the food chain
C. would be broken down in the sea D. wouldn’t do much harm to the sea

A. most fish and sea animals live at the surface of the seas
B. it is very difficult to break the balance of a food chain
C. excessive fishing has caused the decrease in fish stock
D. it won’t be long before the problems concerning oceans will be solved
49. Which of the following is NOT a way being used to protect oceans?
A. The use of international agreements.
B. Forbidding fishing to protect fish stocks.
C. The use of new techniques.
D. Raising people’s awareness of the need to protect oceans.
50. What would be the best title of the passage?

The world is not only hungry, it is also thirsty for water. This may seemstrange to you, since nearly 75％of the earth's surface is covered with water. But about 97％ of this huge amount is seawater, or salt water. Man can only drink and use the other 3％--the fresh water that comes from rivers, lakes, underground, and other sources. And we cannot even use all of that, because some of it is in the form of icebergs and glaciers. Even worse, some of it has been polluted.
However, as things stand today, this small amount of fresh water, which is constantly being replaced by rainfall is still enough for us. But our need for water is increasing rapidly almost everyday. Only if we take steps to deal with this problem now can we avoid a severe worldwide water shortage later on. A limited water supply would have a bad effect on agriculture and industry. Let me give you just one small example of how necessary water is to industry. Did you know that to produce a single ton of steel, it takes about 91000 litres of water?
We all have to learn how to stop wasting our precious water. One of the first steps we should take is to develop ways of reusing it. Experiments have already been done in this field, but only on small scale. The systems that have been worked out are similar to those used in spacecraft.
(1) “The world...is also thirsty for water.” this means that ________.
[ ]
A．the world has not enough fresh water to meet our future needs
B．people all over the world are thirsty for water now
C．we are now facing a serious problem of world-wide water shortage
D．we cannot make use of all the fresh water on earth
(2) According to the passage, only about ________ of the earth's surface is covered with fresh water that can be used.
[ ]
(3) We may face a severe worldwide water shortage in the future because ________.
[ ]
A．the small amount of fresh water is constantly being replaced by rainfall
B．some of it has been polluted
C．some of it is in the form of icebergs and glaciers
D．our need for fresh water is increasing rapidly
(4) According to the passage, one of the first problems is ________.
[ ]
A．to deal with water problem now
B．to have lectures on the water subject
C．to develop ways of reusing water
D．to work out systems that resemble those used in spacecraft
(5) This passage is mainly about ________.
[ ]

Muhammad Yunus and the bank he founded are honored for their work to help the word’s poor. Muhammad Yunus and the Grameen Bank he founded were awarded the Nobel Peace Prize on Friday. They won the award for their efforts to help bring millions of people, especially women, out of poverty.
“Every single individual on earth has both the potential and the right to live a decent life. Across cultures and civilizations, Yunus and Grameen Bank have shown that even the poorest of the poor can work to bring about their own development,” the Nobel Committee said in its citation.
The Peace Prize is one of the biggest honors in the world. Yunus is the first Nobel Prize winner from Bangladesh, a nation of about 141 million people. In 1983, Yunus and the Grameen Bank started a now worldwide system that lets people borrow small amounts of money to start business. Through these loans, called “micro-credit”, the world’s poor have been able to buy much needed to run an egg business, or a cell phone in places where there is on other access to a phone.
Yunus said he would use part of the $1.4 million award money to create a company that will make low-cost, high-nutrition food for the poor. The rest of his share will go toward setting up an eye hospital for the poor in Bangladesh. ”I’m so, so happy, it’s really great news for the whole nation,” Yunus said after hearing of his win.
Since the bank began, it has lent $5.72 billion to more than 6 million Bangladeshis. About 97% of the borrowers are women.
Why does Nobel Peace Prize come to Muhammad Yunus and the Grameen Bank?
A．Because they helped the rich become richer.
B．Because they helped children to finish their education.
C．Because they helped millions of people, especially women, out of poverty.
D．Because they helped millions of people, especially men, out of poverty.
What value have Yunus and Grameen Bank demonstrated to use according to the Nobel Committee’s praise?
A. Poor people have no right to live a rich life
B. Poor people can live a happier life by borrowing money from moneylenders.
C. The poorest of the poor can also have a happier life by working hard.
D. The poor people can only have a right to live a poor life.
It can be inferred that micro-credit system ____.
A. has made all the people in Bangladesh start their own business
B. has a history of about 23 years
C. only loaned money to the people of Bangladesh
D. has spread all over the world for thirty years
Which of the following do you think is true according to this passage?
A. The award money will be used in setting up an eye hospital and a food company for the poor.
B. All the $1.4 million award money will be shared by the poor in Bangladesh
C. Muhammad Yunus will loan the money to the poor women in Bangladesh
D. Muhammad Yunus will save the $1.4 million award money in Grameen Bank.

We all have to learn how to stop wasting our valuable water．One of the first steps is to develop ways of reusing it．
Today in most large cities，water is used only once and then sent out into a sewer system．From there it returns to the sea or runs into underground storage tanks．But it is possible to pipe used water to a purifying plant．There it can be treated with chemicals so that it can be used again，just as if it were fresh from a spring．
But even if every large city purified and reused its water，we still would not have enough．All we'd have to do make use of the vast reserves of sea water in the world is to remove the salt．
If we take these steps we'll be in no danger of drying up．
56．The world is thirsty for water because we can only use percent of the water covering the surface of the earth．
A．3 B．more than 3 C．less than 3 D．97
