阅读材料，回答题。Trees are useful to man in three important ways: they provide him with woo

阅读材料，回答题。

Trees are useful to man in three important ways: they provide him with wood and other products; they give him shade; and they help to prevent droughts and floods.

Unfortunately, in many parts of the world, man has not realized that the third of these services is the most important. In his eagerness to make money from trees, he has cut them down in large numbers, only to find that without them he has lost the best friends he had. And besides, he is usually too careless to plant and look after new trees. So the forests slowly disappear.

This does not only mean that man will have fewer trees. The results are even more serious for where there are trees, their roots break up soil allowing the rain to sink in and also bind the soil, thus preventing it from being washed away easily; but where there are no trees, the rain fall son hard ground and flows away, causing floods and carrying away the rich topsoil. When all the topsoil is gone, nothing remains but worthless desert.

Two thousand years ago a rich and powerful country cut down its trees to build warships, with which to gain itself an empire. It set up the empire but, without its trees, its soil became poor and it grew weak. When the empire fell to pieces, the home country found itself faced with floods and starvation.

What is the most important service of trees to man according to the passage？查看材料

A.They help him make money

B.They give him wood and other products

C.They help him prevent droughts and floods

D.They give him shade

第6题

The garbage does not simply disappear.It may go on to a transfer station.Since it is

difficult and expensive to dispose at landfill sites and incinerators .People are encouraged to recycle and compost (堆肥) picked up and taken and will be carefully buried or burned.The problem with these methods othey cost money, take up land and cause pollution.

One solution to the problem of solid waste disposal is composting.Some things that can beand vegetable peels.People can compost these food products by placing them in an outdoor decompose(分解 ) into a substance called compost.Compost, which contains plant nutrients, cto help other plants grow.

Within a large concrete room, cut out of a mountain on a freezing-cold island just 1,000 k

ilometers from the North Pole, could lie the future of humanity.

The room is a vault (地下库) designed to hold around 2 million seeds, representing all known varieties of the world's crops. It is being built to safeguard the world's food supply against nuclear war, climate change, terrorism, rising sea levels, earthquakes and the collapse of electricity supplies. "If the worst came to the worst, this would allow the world to reconstruct agriculture on this planet," says Cary Fowler, director of the Global Crop Diversity Trust, an independent international organization promoting the project.

The Norwegian (挪威的) government is planning to create the seed bank next year at the request of crop scientists. The $3 million vault will be built deep inside a sandstone mountain on the Norwegian Arctic island of Spitsbergen. The vault will have metre-thick walls of reinforced concrete and will be protected behind two airlocks and high-security doors.

The vault's seed collection will represent the products of some 10, 000 years of plant breeding by the world's farmers. Though most are no longer widely planted, the varieties contain vital genetic properties still regularly used in plant breeding.

To survive, the seeds need freezing temperatures. Operators plan to replace the air inside the vault each winter, when temperatures in Spitsbergen are around -18℃. But even if some disaster meant that the vault was abandoned, the permanently frozen soil would keep the seeds alive. And even accelerated global warming would take many decades to penetrate the mountain vault.

"This will be the world's most secure gene bank," says Fowler. "But. its seeds will only be used when all other samples have gone for some reason."

The project comes at a time when there is growing concern about the safety of existing seed banks around the world. Many have been criticized for their poor security, ageing refrigeration (冷藏) systems and vulnerable electricity supplies.

The scheme won UN approval at a meeting of the Food and Agriculture Organization in Rome in October 2005. A feasibility study said the facility "would essentially be built to last forever".

The Norwegian vault is important in that ______.

A．the seeds in it represent the rarest varieties of world's crops

B．the seeds in it could revive agriculture if the worst thing should happen

C．it is built deep in a mountain on a freezing-cold Arctic island.

D．it is strong enough against all disasters caused by man and nature

第10题

Most animals have little connection with animals of different kind, unless they hunt t

hem for food. Sometimes, however, two kinds of animals come together in a partnership (伙伴关系 ) which does good to both of them. You may have noticed some birds sitting on the backs of sheep. This is not because they want a ride, but because they find easy food in the parasites (寄生虫 ) on sheep. The sheep allow the birds to do so because they remove the cause of discomfort. So although they can manage without each other, they do better together.

Sometimes an animal has a plant partner. The relationship develops until the two partners cannot manage without each other. This is so in the corals (珊瑚 ) of the sea. In their skins they have tiny plants act as "dustman", taking some of the waste products form. the corals and giving in return oxygen which the animal needs to breathe. If the plants are killed, or are ever prevented from lighting so that they cannot live normally, the corals will die.

1、Some birds like to sit on a sheep because ().

A、they can eat its parasites

B、 they depend on the sheep for existence

C、 they enjoy traveling with the sheep

D、 they find the position most comfortable

2、The underlined word "they" in the last sentence of the first paragraph refers to ().

A、birds and parasites

B、birds and sheep

C、parasites and sheep

D、sheep, birds and parasites

3、What does the second paragraph mainly discuss？ ()

A、Some animals and plants depend on each other for existence.
