【題目】根據(jù)短文理解，選擇正確答案。
Computer technology is still developing rapidly. The computer of the future will continue to increase in value and performance while decreasing in cost. It will become smaller, but faster and more powerful.
It is possible to make some guesses about what the future of the computer will look like, based upon the types of technologies that are being developed now. A lot of progress has already been made in some of these new technologies, but some are still in their earliest stages and may not be ready for use for years. Two of the most interesting areas of computing that are currently being developed are quantum computing (量子計(jì)算) and nanotechnology (納米技術(shù)).
Quantum computing is one possibility for the future of the computer that could make computers run far faster than even the quickest computers do today. Quantum computers could be able to do what modern supercomputers are unable to do by using transistors that are able to take on many states at the same time.
Nanotechnology could also change the face of computing, by creating computers that could be very powerful, though they are tiny in size. These computers could be incorporated (并入) into everyday objects, including electrical appliances (電器), clothes and even the human body. We will be able to use computers in new and unimaginable ways. They will become a part of our lives rather than simply being a box that is used only for specific purposes, such as work.
Quantum computing and nanotechnology will be able to play new roles, which will make us live greener lives, as well as enjoy better health and happier lives.
（1）Which of the following can NOT describe the computer of the future properly?
A.Much smaller.
B.Much faster.
C.More powerful.
D.Less valuable.
（2）According to the text, quantum computing _____.
A.has been put in use so far
B.can make computers run by themselves
C.can reduce the cost of computers
D.will work by using transistors
（3）We can learn from the text that nanotechnology will _____.
A.create much smaller computers
B.be used in electrical appliances and clothing
C.change the structure of computers
D.make computers just serve specific purposes
（4）The text is mainly about _____.
A.what nanotechnology is
B.what quantum computing is
C.what the future of the computer is
D.what future computers can bring us

【答案】
（1）D
（2）D
（3）A
（4）C
【解析】本文描述了將來電腦技術(shù)的發(fā)展，尤其指出在量子計(jì)算和納米技術(shù)方面的應(yīng)用。

（1）D細(xì)節(jié)理解題。根據(jù)第一段The computer of the future will continue to increase in value and performance while decreasing in cost. It will become smaller, but faster and more powerful.可知將來的電腦會更小，更快，更強(qiáng)大，同時價值更高，表現(xiàn)會更好。所以更沒價值是不對的，故正確答案為D。

（2）D細(xì)節(jié)理解題。根據(jù)文章的第三段Quantum computers could be able to do what modern supercomputers are unable to do by using transistors that are able to take on many states at the same time可知，量子計(jì)算可以使用晶體管做現(xiàn)代超級計(jì)算機(jī)不能做的事。故選D。

（3）A推理判斷題。根據(jù)文章第四段的第一句Nanotechnology could also change the face of computing, by creating computers that could be very powerful, though they are tiny in size.可看出納米技術(shù)會讓電腦的尺寸更小。故選A。

（4）C 主旨大意題。通讀全文可知，本文主要描述將來的電腦會是什么樣的，故選C。

【題目】根據(jù)短文理解，選擇正確答案。
Scientists in Argentina have created the world's first cow with two human genes that will enable it to produce human-like milk.
Genetic engineering was used to introduce the "mothers'milk" genes into the animal before birth, according to the National Institute of Agribusiness Technology in Buenos Aires.
As an adult, the cloned cow "will produce milk that is similar to that of humans", which will prove "a development of great importance for the nutrition of infants(嬰兒)", said the institute. "The cloned cow, named Rosita ISA, is the first in the world with two human genes that contain the proteins present in human milk," said the statement.
In April, scientists in China published details of research showing that they had created dairy cows which produced milk containing proteins found in human breast milk. But the Argentine team said the Chinese only introduced one human gene, while their research involved two, meaning the milk will more closely resemble that of humans.
“Our goal was to raise the nutrition value of cows'milk by adding two human genes, which do good to the immune system of infants,” said Adrian Mutto, from the National University of San Martin which worked with the institute.
Cristina Kirchner, President of Argentina, said that the scientific institute made all Argentines proud. She also said that she had rejected the "honor" of having the cow named after her. "They came to tell me that the name is Cristina, but what woman would like to have a cow named after her? It appeared to me to be more proper to call it Rosita.”
（1）What is the passage mainly about?
A.The importance of genetic engineering.
B.Ways to improve mothers' milk.
C.A cloned cow to produce human-like milk.
D.Advanced agricultural technology in Argentina.
（2）Which of the following can best replace “more closely resemble” in Paragraph 4?
A.have more varieties than
B.be more similar to
C.have more nutrition than
D.be more different from
（3）What can be inferred from Cristina Kirchner's statements?
A.She was quite satisfied with the research done by the institute.
B.She considered it an honor to name the special cow.
C.She felt it improper to be named after the cow.
D.She refused to give a name to the cow out of self-respect.
