Batteries can power anything from small sensors to large systems. While scientists are finding ways to make them smaller but even more powerful, problems can arise when these batteries are much larger and heavier than the devices themselves. University of Missouri (MU) researchers are developing a nuclear energy source that is smaller, lighter and more efficient.

“To provide enough power, we need certain methods with energy density (密度),” said Jae kwon, assistant professor of electrical and computer engineering at MU. “The radioisotope (放射性同位素) battery can provide power density that is much higher than chemical batteries.”

Kwon and his research team have been working on building a small nuclear battery, recently the size and thickness of a penny, intended to power various micro/nano-electromechanical systems (M/NEWS). Although nuclear batteries can cause concerns, Kwon said they are safe.

“People hear the word ‘nuclear’ and think of something very dangerous,” he said. “However, nuclear power sources have already been safely powering a variety of devices, such as pace-makers, space satellites and underwater systems.”

His new idea is not only in the battery’s size, but also in its semiconductor (半导体). Kwon’s battery uses a liquid semiconductor rather than a solid semiconductor.

“The key part of using a radioactive battery is that when you harvest the energy, part of the radiation energy can damage the lattice structure (晶格结构) of the solid semiconductor, ” Kwon said. “By using a liquid semiconductor, we believe we can minimize that problem.”

Together with J. David Robertson, chemistry professor and associate director of the MU Research Reactor, Kwon is working to build and test the battery. In the future, they hope to increase the battery’s power, shrink its size and try with various other materials. Kwon said that the battery could be thinner than the thickness of human hair.

Which of the following is true of Jae Kwon?

A. He teaches chemistry at MU.

B. He developed a chemical battery.

C. He is working on a nuclear energy source.

D. He made a breakthrough in computer engineering.

Jae Kwon gave examples in Paragraph 4 ________.

A. to show chemical batteries are widely applied

B. to indicate nuclear batteries can be safely used

C. to describe a nuclear-powered system

D. to introduce various energy sources.

Liquid semiconductor is used to ________ .

A. get rid of the radioactive waste

B. test the power of nuclear batteries

C. decrease the size of nuclear batteries

D. reduce the damage to lattice structure

According to Jae Kwon, his nuclear battery ________.

A. uses a solid semiconductor B. will soon replace the present ones

C. could be extremely thin D. has passed the final test

The text is most probably a ________.

A. science news report B. book review

C. newspaper ad D. science fiction story

It happened to me recently. I was telling someone how much I had enjoyed reading Barack Obama’s Dreams From My Father and how it had changed my views of our President. A friend I was talking to agreed with me that it was ,in his words, “a brilliantly（精彩地）written book”. However, he then went on to talk about Mr Obama in a way which suggested he had no idea of his background at all. I sensed that I was talking to a book liar.

And it seems that my friend is not the only one. Approximately two thirds of people have lied about reading a book which they haven’t. In the World Book Day’s “Report on Guilty Secrets”, Dreams From My Father is at number 9. The report lists ten books, and various authors, which people have lied about reading, and as I’m not one to lie too often (I’d hate to be caught out ),I’ll admit here and now that I haven’t read the entire top ten . But I am pleased to say that, unlike 42 percent of people, I have read the book at number one, George Orwell’s 1984. I think it’s really brilliant.

The World Book Day report also has some other interesting information in it. It says that many people lie about having read Jane Austen, Charles Dickens, Fyodor Dostoevsky(I haven’t read him, but haven’t lied about it either )and Herman Melville.

Asked why they lied, the most common reason was to “impress” someone they were speaking to. This could be tricky if the conversation became more in –depth!

But when asked which authors they actually enjoy, people named J. k. Rowling, John Grisham, Sophie Kinsella (ah, the big sellers, in other words). Forty-two percent of people asked admitted they turned to the back of the book to read the end before finishing the story(I’ll come clean: I do this and am astonished that 58 percent said they had never done so).

1.How did the author find his friend a book liar?

A．By judging his manner of speaking.

B．By looking into his background.

C．By mentioning a famous name.

D．By discussing the book itself.

2.Which of the following is a “guilty secret” according to the World Book Day report?

A．Charles Dickens is very low on the top-ten list.

B．42% of people pretended to have read 1984.

C．The author admitted having read 9 books.

D．Dreams From My Father is hardly read.

3.By lying about reading, a person hopes to.

A．control the conversation

B．appear knowledgeable

C．learn about the book

D．make more friends

4.What is the author’s attitude to 58%of readers?

A．Favorable.

B．Uncaring

C．Doubtful

D．Friendly

It happened to me recently that I was telling someone how much I had enjoyed reading Barack Obama’s Dreams from My Father and how it had changed my views of the current US president. The person I was talking to agreed with me that it was, in his words, “a wonderfully written book”. However, he then proceeded to talk about Mr. Obama in a way that suggested he had no idea of his background at all. I sensed that I was talking to a book liar.

And it seems that he is not the only one. Clearly two thirds of people have lied about reading a book which they haven’t. In the World Book Day survey, Dreams from My Father is at number 9. The survey lists top ten books, and various authors, which people have lied about reading. As I’m not one to lie too often, I’ll admit here and now that I haven’t read the entire ten books. But I am pleased to say that I have read the book at number one, George Orwell’s 1984. I think it’s absolutely outstanding.

Asked why they lied, the most common reason was to impress someone they were speaking to. This could be difficult if the conversation became more in depth!

The World Book Day survey also has some other interesting information in it. It shows that many people lie about having read classical works by Jane Austen, the Bronte sisters, Charles Dickens and so on. But when asked which authors they actually enjoy, they named J.K. Rowling, Jilly Cooper, and Stephen King (ah, the big sellers, in other words). Forty-one percent of people asked admitted they turned to the back of the book to read the end before finishing the story.

So which books have you lied about reading — if any — and which is your favourite?

1．The main reason why people lie about reading is to _________.

A. make fun of the listener B. impress the listener

C. please the listener D. interest the listener

2．The underlined word “proceeded” in the passage probably means “_________”.

A. wanted B. happened C. continued D. stopped

3．What does the World Book Day survey show?

A. Nearly half of the people surveyed didn’t read through a whole classical book.

B. People don’t like Dreams from My Father and George Orwell’s 1984.

C. Few people lie about having read classical works by Jane Austen.

D. People usually enjoy reading books by Charles Dickens.

4．What is the best title for the passage?

A. Are You a Book Liar? B. Readers Are All Liars

C. World Book Day D. Dreams from My Father
