[单项选择]Gravity is a slippery beast. We don’t know how strong it is, how it works or how fast its effects move. But this year we made progress.
October saw the most accurate measurement yet of Newton’s gravitational constant(引力常数 ), G, a measure of the strength of the gravitational interaction between two objects. A Swiss team calculated G’s value by measuring how the gravitational pull of two huge tanks of mercury affected the weights of test masses.
However, there are discrepancies between measurements of G made in different labs. This year a highly contentious(有争议的) explanation for this was proposed. A group of string theorists proposed that gravity is subtly affected by magnetic fields, and that G should be larger near Earth’s poles where the magnetic field is stronger. Sure enough, this fits with the measurements so far. So G’s varying values might just be the first proof of the hidden dimensions predicted by string theory.
Equally tantalising is possible evidence for the e
A. Because it gives people so much trouble.
B. Because it is much stronger than expected.
C. Because no progress has been made about it.
D. Because it remains largely unknown to peopl

[单项选择]We don’t know how the first fire was made. Early fires on the earth were certainly caused by nature, not by man. Some were caused by lightning in a storm; others, perhaps by one hot material which came out of a volcano (火山). Quite possibly, at times, the heat of the sun set light to some dry grass or leaves. At first, man like other animals, was probably afraid of fire. He saw that fire could destroy a forest; he knew that fire could hurt his body. So great was the power of fire that he feared it and worshipped it. Gradually, however, with his better powers of thinking, he overcame his fear. Probably he overcame most of his fear when he discovered how to make fire for himself, but, undoubtedly, he learned some of the uses of fire before he could make one when and where he wished. Throughout the ages he has learned more about fire, how to control it, and how to use it in many ways. Now fire is no longer a master or a god, it is a servant.
Again, at some early date, Man found how fi

[单项选择]

I don’t know how I became a writer, but I think it was because of a certain force in me that had to write and that finally burst through and found a channel. My people were of the working class of people. My father, a stone-cutter, was a man with a great respect and veneration for literature. He had a tremendous memory, and he loved poetry, and the poetry that he loved best was naturally of the rhetorical kind that such a man would like. Nevertheless it was good poetry, Hamlet’s Soliloquy, Macbeth, Mark Antony’s “Funeral Oration”, Grey’s “Elegy”, and all the rest of it. I heard it all as a child; I memorized and learned it all.
He sent me to college to the state university. The desire to write, which had been strong during all my days in high school, grew stronger still. I was editor of the college paper, the college magazine, etc. , and in my last year or two I was a member of a course in playwriting which had just been est
A. when he was in high school
B. when he was studying at Harvard
C. when he lived in London
D. after he entered college
