Ⅱ.阅读理解
A
Brian Greene, a professor of physics and mathematics at Columbia University, has created an online science education platform. He tries to “build a bridge” with things you know about, and then “bring you across that bridge to the strange place of modern physics”．
Recently I had a chance to ask Greene about wormholes (a hole which some scientists think might exist, connecting parts of space and time that are not usually connected), time travel and other mysteries of the universe. I asked him a million­dollar question：W hat if I went through a wormhole and prevented my parents from meeting? “Most of us believe that the universe makes sense，” Greene said. Although there are several interesting theories about time travel, he added, the laws of physics would probably prevent something so illogical from taking place. The good news is that the time paradox (悖论) is open for future physicists to solve.
When asked how physics could become more exciting for kids, Greene said that books by Stephen Weinberg, Leonard Susskind, and other physicists, “make it a great time for people who want to learn about big ideas but aren't yet ready，perhaps, to learn math. ”
When I pointed out that some students still might find physics boring, Greene said that the key is to teach them about things that are strange. “The basic stuff is important，” Greene said. “But I think it's really important to also describe the more modern ideas, things like black holes and the Big Bang. If kids have those ideas in mind, then at least some of them will be excited to learn all the details. ”
Greene has followed Albert Einstein's lead in trying to solve the mysteries of the universe. Now he wants kids to do the same. As Greene said, physics is “not just a matter of solving problems in an exam”. It's about experimenting, showing an interest in strange phenomena (现象)—and having fun!

物理学家Brian Greene希望更多的孩子能够对现代物理学感兴趣。

1．A million­dollar question is probably very ．
A．direct B．difficult
C．personal D．long
B[细节理解题。

根据第二段Greene对这个问题的解释以及他说需要未来的物理学家去解决可知，这个问题可能非常难。

2．The books by Weinberg and Susskind ．
A．are boring to read
B．are mainly about math
C．are popular science books
D．are only popular among kids
C[推理判断题。

根据第三段的“...books by...make it a great time for people who want to learn about big ideas but aren't yet ready, perhaps, to learn math”可知，Greene认为Weinberg和Susskind等物理学家写的书浅显易懂，适合大众阅读，故这些书属于科普读物。

3．According to Paragraph 4, which of the following does Greene agree with?
A．Modern physics is a boring subject.
B．Interest plays an important role in studying.
C．It is not necessary to learn all about physics.
D．It is easy to describe black holes and the Big Bang.
B[推理判断题。

根据第四段可知，当作者指出一些学生觉得物理无聊时，Greene说重要的是向孩子们讲述一些稀奇古怪的事，并描述一些诸如黑洞和宇宙大爆炸的现代物理现象，如果孩子们知道了这些，他们就愿意了解更多详细的内容。

因此他认为兴趣在学习过程中起着非常重要的作用。

4．In the last paragraph，Greene hopes that ．
A．kids can love science and physics
B．kids can do well in physics exams
C．kids can have fun with experiments
D．kids can find more strange things in life
A[推理判断题。

根据最后一段的“Greene has followed Albert Einstein's lead in trying to solve the mysteries of the universe.Now he wants kids to do the same.”可知，Greene希望孩子们可以像他一样对科学和物理感兴趣，去探索宇宙的奥秘。

B
Sir John Gurdon, a British scientist, who won the Nobel Prize in Physiology or Medicine in 2012，said he had predicted at the time of his frog experiments that the successful cloning of a mammal would happen within 50 years, and that “maybe the same answer is appropriate” for the step to human cloning. Parents who lose children in accidents may be able to clone “copies” to replace them then.
Although any attempt to clone an entire human would raise complex moral issues, the biologist claimed people would soon overcome their concerns if the technique became medically useful. Cloning was regarded with extreme doubts when it was first developed but became widely accepted after the birth of Louise Brown, the first “test­tube baby”. He said，“When my first frog experiments were done, an American reporter asked how long it would be before these things could be done in mammals or humans. I said,‘Well, it could be anytime between 10 years and 100 years—how about 50 years？’ It turned out that it wasn't far off the mark as far as Dolly was concerned. Maybe the same answer is appropriate. ” Sir John added that cloning a human being effectively means making an identical twin, and doctors would therefore simply be “copying what nature has already produced”．
The average vote on allowing parents of deceased children, who are no longer fertile (能生育的), to create another by using the mother's eggs and skin cells from the first child, thinking the technique was safe and effective, is 60 percent in favor. The reasons for “no” are usually that the new children would feel they are some sort of replacements for something.

诺贝尔生理学或医学奖得主、英国科学家约翰·格登爵士称，那些在事故中失去子女的父母将能在未来50年内借助克隆技术，让他们的子女得到“重生”。

5．Sir John predicted the human cloning would be a reality in at most.
A．about 100 years B．about 60 years
C．about 50 years D．about 10 years
C[细节理解题。

根据文章第一段可知，格登爵士表示，在未来50年内，那些在事故中失去孩子的父母将有可能通过克隆技术得到孩子的“复制品”。

]
6．According to the text, which statement is NOT true?
A．Louise Brown is the first “test­tube baby”．
B．Human cloning is still a controversial topic.
C．Sir John is positive about the future of human cloning.
D．Human cloning is creating something that didn't exist before.
D[细节理解题。

根据第二段中的“after the birth of Louise Brown，the first‘test ­tube baby’”可排除A项；文章尾段说明赞成者占六成，故排除B项；根据第二段中格登爵士的话可知，他对克隆人充满了希望，故排除C项；根据第二段的尾句可知，D项表述不正确。

] 7．The underlined word “identical” probably means“”
A．same B．special C．new D．clear
A[词义猜测题。

根据画线词后的“twin”和“doctors would therefore simply be ‘copying what nature has already produced’”可知，A项正确。

]
8．It can be inferred from the passage that ．
A．most people cast doubt on John's experiments
B．human cloning is and will be only a dream
C．few children love to be cloned in the future
D．human cloning may be realized someday
D[推理判断题。

根据文章第二段的第一句可知，虽然克隆人类的尝试将引起复杂的道德问题，但是生物学家声称如果克隆技术变得有医学价值，人们很快就会消除他们的担心。

] Ⅲ.阅读七选五
There is an old Spanish proverb which states, “Tomorrow is often the busiest day of the week. ” 1 Too many. But our dreams should not and cannot wait.
Tomorrow is not promised.
Nobody likes to talk about death, but the reality is that everybody will die some day. None of us know the day. 2 Don't go to your grave with unfinished dreams. Make the decision to go after every dream, big or small, right now.
The world is waiting for your gift.
The world is waiting for you. 3 Sure, other people may be able to sing, but they'll never be able to sing exactly like you. Sure, other people can write, but they'll never be able to write from the same point of view in which you write.
4
You can dream about writing a great novel, but it's never going to happen unless you actually put your pen to paper. You can dream about finding a cure for cancer, but it will never happen unless you actually go to school to become equipped with the necessary tools to find that cure.
You can't let fear wi n.
One of the biggest dream killers is fear. There are so many people who could have achieved amazing things if they weren't afraid. Just think about all the things you've wanted to do, but allowed fear to convince you that you weren't capable or good enough.
5 You can choose not to let fear stop you from achieving your dreams.
