We must do what we can to protect the plants because plants are very important for living things. Life could not go on if there were no plants. This is because plants can make food from air, water and sunlight. Animals and man cannot make food from air, water and sunlight. Animals get their food by eating plants and other animals. Therefore animals and man need plants in order to live. This is why we find that there are so many plants around us.
If you look carefully at the plants around you, you will find that there are two kinds of plants: flowering plants and non-flowering plants. Flowering plants can make seeds. The seeds are protected by the fruits. Some fruits have one seed, some have two, three or four, and some have many seeds. But a few fruits have no seeds at all. An example of a fruit without seeds is the banana fruit. Most non-flowering plants do not grow from seeds. They grow from spores（胚芽）. Spores are very small. Some spores are so small and light that they can float in the air. We may say that spores are quite the same as seeds. When these spores are all on wet and shady places, they usually grow into new plants.

| A．flower, water and air | B．water, sunlight and air |
| C．air, water and soil | D．air, sun and light |

【小題1】B
【小題2】A
【小題3】D
【小題4】C
【小題5】D
解析【小題1】細節理解題。根據第一段的第三句話：“plants can make food from air, water and sunlight. ”可知，答案選B。
【小題2】主旨大意題。根據第一段的前兩句話可知植物對于生命是很重要的，接著給出了原因，動物不能制造食物，只能吃掉植物或動物，只有植物能夠利用空氣、陽光和水制造食物，所以答案選A。
【小題3】推理判斷題。通讀全文可知，植物能夠利用空氣、陽光和水制造食物，動物不能制造食物，只能吃植物或動物，離開了植物，動物包括人類都要死亡，故選D；文中沒有突出動物的重要性，故A是錯誤的；孢子和種子是兩種不同的繁殖方式，故B是錯誤的；香蕉這種開花植物的果實就沒有種子，故C是錯誤的。
【小題4】推理判斷題。本文講述的是植物的重要性以及繁殖方式，很顯然是一篇科普文章，故選C。
【小題5】推斷詞義題。結合常識可知，有果實的植物種子往往在果實內部，果實起著保護種子的作用。所以protected應是“保護”的意思，有guarded相近。

1970 was World Conservation Year. The United Nations wanted everyone to know that the world is in danger. They hoped that governments would act quickly in order to conserve nature. Here is one example of the problem. At one time there were 1,300 different plants, trees and flowers in Holland but now only 866 remain. The others have been destroyed by modern man and his technology. We are changing the earth, the air and water, and everything that grows and lives. We can’t live without these things. If we continue like this, we shall destroy ourselves.
What will happen in the future? Perhaps it is more important to ask “what must we do now?” the people who will believe in the world of tomorrow are the young of today. A lot of them know that conversation is necessary. Many are helping to save our world. They plant trees, build bridges across rivers in forests, and so on. In a small town in the United States a large group of girls cleaned the banks of 11kilometers of their river. Young people may hear about conservation through a record called “no one’s going to change our world.” It was made by the Beatles, Cliff Richard, and other singers. The money from it help to conserve wild animals.
There are fewer plants, trees and flowers in Holland now because________
A. There has been a lot of conservation in Holland
B. Holland does not need so many plants, trees and flowers
C. many plants, trees and flowers do not grow there any more
D. some plants, trees and flowers are dangerous
We shall destroy ourselves if we don’t change_______
A. The United Nations
B. modern technology
C. our rivers and forests
D. the government of Holland
“No one’s going to change our world” was________
A. an important book published in 1970
B. an idea that nobody would accept
C. a record calling all people to conserve nature
D. a rule worked out by the United Nations
What is the most important thing for us to do to save our world?
A. we should plant more trees and flowers
B. we should clean the banks of our rivers
C. we should know what will happen in the future
D. we should know what we must do and begin to do now

“People should have one meat-free day a week if they want to make a personal and effective sacrifice that would help deal with climate change,” the world’s leading authority on global warming has told The Observer.
Dr Rajendra Pachauri, chair of the United Nations Intergovernmental Panel on Climate Change, said that people should then go on to reduce their meat consumption even further.
Pachauri, who was re-elected the panel’s chairman for a second six-year term last week, said diet change was important because of the huge greenhouse gas emissions (排放) and other environmental problems associated with raising cattle and other animals. “It was relatively easy to change eating habits compared to changing means of transport,” he said.
The UN’s Food and Agriculture Organisation has estimated that meat production accounts for nearly a fifth of global greenhouse gas emissions. These are produced during the production. For example, ruminants (反芻動物), particularly cows, give off a gas called methane, which is 23 times more effective as a global warming agent than CO2.
Pachauri can expect some opposite responses from the food industry to his advice, though last night he was given unexpected support by Masterchef presenter and restaurateur John Torode. “I have a little bit and enjoy it,” said Torode. “Too much for any person is bad. But there’s a bigger issue here: where the meat comes from. If we all bought British and stopped buying imported food, we’d save a huge amount of carbon emissions.”
Professor Robert Watson, the chief scientific adviser for the Department for Environment Food and Rural Affairs, said government could help educate people about the benefits of eating less meat, but it should not regulate. “Eating less meat would help, there’s no question about that,” Watson said.
However, Chris Lamb, head of marketing for pig industry group BPEX, said the meat industry had been unfairly targeted and was working hard to find out which activities had the biggest environmental impact and reduce them. “Some ideas were contradictory,” he said. “For example, one solution to emissions from cattle and other animals was to keep them indoors, but this would damage animal welfare. Climate change is a very young science and our view is there are a lot of simple solutions being proposed.”
1.What is directly related to global warming?
|
A．Consumption of meat. |
B．Growth of cattle. |

2.Who holds a view opposite to the others’ in the passage?
|
A．Rajendra Pachauri. |
B．John Torode. |
C．Robert Watson. |
D．Chris Lamb. |
3.It is implied in the passage that _____.
|
A．we should try to keep away from cattle |
B．ruminants should not be left outdoors |
|
C．the meat industry will soon close down |
D．we must do our duty to save the earth |
4. Which of the following might be the best title for the passage?
|
A．Less meat, slower global warming |
|
B．More animals, more greenhouse gas |
|
C．Less imported food, better our environment |
|
D．Greater diet change, smaller climate change |
