【题目】根据短文理解,选择正确答案。
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 (量子计算) and nanotechnology (纳米技术).
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 (电器), 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】本文描述了将来电脑技术的发展,尤其指出在量子计算和纳米技术方面的应用。

(1)D细节理解题。根据第一段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.可知将来的电脑会更小,更快,更强大,同时价值更高,表现会更好。所以更没价值是不对的,故正确答案为D。

(2)D细节理解题。根据文章的第三段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,量子计算可以使用晶体管做现代超级计算机不能做的事。故选D。

(3)A推理判断题。根据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.可看出纳米技术会让电脑的尺寸更小。故选A。

(4)C 主旨大意题。通读全文可知,本文主要描述将来的电脑会是什么样的,故选C。

【题目】Choosing the right college for you is not so easy. You should have a general idea of what you want and don’t want. The idea can guide you to find what fits your needs best.1

Think about what major you want to study in college. If you know that, just look at colleges that have your major.2So think carefully about your major and interests before choosing one.

Where the college is located matters. Anyone who tells you the location isn’t important is lying.3If you look forward to working in the publishing industry, New York may be your best bet. If your parents want you to stay close to home, please don’t consider anywhere that requires a plane ticket to get to.

Think about how much you can afford. Are your parents paying for your education? If so, how much are they willing to spend? Do you have to contribute anything? Financial aid and scholarships exist, but don’t count on anything. 4These are all things to consider before you fall in love with a college.

Make sure you’re going to spend time with the right people. The cool thing about college is that each different one attracts different kinds of people. For the first thing in your life, you get to choose where you get to spend your time and who you get to spend it with. 5Make sure that the people you’re with for four years are your kind of people.

A. College is about learning what you love.

B. You’d better choose a major that is popular.

C. Go to the college with some people you like.

【题目】根据短文理解,选择正确答案。
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(婴儿)", 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.
