Passage One

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 A. magnetic fields affect gravity subtly B. G is larger near the Earth’s poles C. G has a number of hidden dimensions D. discrepancies emerge between measures of G 查看答案 更多"Passage One Gravity is a "的相关试题: [单项选择] Passage One Gravity is a slippery beast.

Because it remains largely unknown to people. 查看答案 [单项选择]Passage One One hundred and thirteen million Americans have at least one bank-issued credit card. They give their owners automatic credit in stores, restaurants, and hotels, at home, across the country, and even abroad, and they make many banking services available as well. More and more of these credit cards can be read automatically, making it possible to withdraw or deposit money in scattered locations, whether or not the local branch bank is open. For many of us the "cashless society" is not on the horizon-it’s already here. While computers offer these conveniences to consumers, they have many advantages for sellers too. Electronic cash registers can do much more than simply ring up sales. They can keep a wide range of records, including who sold what, when, and to whom. This information allows businessmen to keep track of their list of goods by showing which items are being sold and how fast they are moving. Decisions to reorder or return goods to su A. withdraw as much money from the bank as he wishes B. obtain more convenient services than other people do C. enjoy greater trust from the storekeeper D. cash money where he wishes to 查看答案 [单项选择] Passage One Passage One I have an infatuation(迷恋)with autumn. The colors of the season, and the smells, have always thrilled me. I have always found joy in this time of year. The last few autumns of my life, however, I recollect in shades of gray rather than cheerful oranges and yellows. When I became a single mother, every aspect of life took on new meaning. Since I was used to carrying out most of the parental duties without much help during my marriage, I truly did not foresee how different parenting would become after the marriage was over. But suddenly I realized I was a statistic. The daily routine was not changed so much; it was the angle at which I had begun to look at life. I believed my ex-husband’s lawyer was tracking every grade the children made, and I was under a microscope in this new town where the children and I A. The author moved to a new place. B. The climate changed greatly in the last few years. C. In the last few years, the author’s mood changed. D. There were some natural disasters. 查看答案 [单项选择]Passage One A.
