阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项。

Because of the energy crisis(危机), scientists in the oil-consuming nations(石油消费国) have become increasingly interested in the potential(潜能) of solar energy. Some experts think that the present supply of fuel(燃料) will not last until the middle of the next century. The problem that solar energy researchers face is how to make use of the sun's energy effectively and inexpensively. One of the most popular methods being tested at present uses roof-top solar collectors and underground storage tanks(罐). An advantage of properly working system of this type is that it will not create any environmental pollution. Another advantage of using solar energy is that the cost of the fuel, the sun's rays, is zero.

1.The main topic of this passage is ________.

[  ]

A.the shortage of fossil(化石) fuel

B.the problems that energy researchers face

C.an environmental pollution problem

D.an inexpensive energy source

2.Which of the following describes an advantage of using solar energy?

[  ]

A.There is little or no environmental pollution.

B.Solar energy can easily be stored.

C.Fossil fuels will become more plentiful(丰富的).

D.The oil-consuming nations will not have to import oil.

3.The cost of using the sun's rays for heating is ________.

[  ]

A.about the same as the cost of fossil fuels

B.several hundred dollars per year

C.negligible(可以忽略的) compared with other energy sources.

D.more than the lost of fossil fuels

阅读理解,阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项。

  Believe it or not, in the near future people won't just wear a chicken feather suit at Halloween or for fancy dress.Chickens, which have long provided food for dinner, will also be used to make our clothes as well.Last Monday, a report by the University of Nebraska in the US said in the future it should be possible to use chicken feathers and rice straw to make clothes.

  “All those wasted agriculture products don't have to be wasted anymore, ” researcher Yiqi Yang said.

  New technology will change these by-products into something similar to wool, linen, or cotton.Because producing synthetic fabrics(合成纤维)causes pollution, scientists wanted to find a cheaper and environmentally friendly replacement.They turned their eyes to the millions of tons of rice straw and chicken feathers that are widely and cheaply available worldwide.Moreover they don't cause pollution like petroleum-based fibers(石油合成纤维).

  Chicken feathers are mostly made up of the same kind of protein found in wool.A sweater made from chicken feathers would feel just like a wool sweater.It would be lighter in weight and warmer, too.

  According to Yang and his team, rice straw, on the other hand, can produce a fabric that looks and feels similar to cotton or linen.The process is also environmentally friendly.The total production cost of rice fiber is about 50 cents per pound, while cotton now sells for about 60 cents a pound.

  Maybe some day in the future you will wear fabulous clothes like these.

(1)

Which of the following is true according to the passage?

[  ]

The environmentally friendly products will take the place of the non-environmentally friendly ones.

D.

Scientists have not made any progress in the environmentally friendly products.

(2)

What are the main advantage of the new clothes made of chicken feathers and rice straw?

[  ]

A.

They are mostly made up of the same kind of protein found in wool.

B.

The clothes will be widely used in every field in our daily life.

C.

The process of producing the clothes does not cheap at all.

D.

A sweater made of the new clothes would be lighter in weight and warmer.

(3)
