1、阅读理解-练习十一及答案解析(总分：40.00，做题时间：90 分钟)一、Test 1(总题数：0，分数：0.00)二、TEXT A(总题数：1，分数：6.00)The word “laser“ was coined as an acronym for Light Amplification by the Stimulated Emission of Radiation. Ordinary light, from the Sun or a light bulb, is emitted spontaneously, when atoms or molecules get rid of exces
2、s energy by themselves, without any outside intervention. Stimulated emission is different because it occurs when an atom or molecule holding onto excess energy has been stimulated to emit it as light.Albert Einstein was the first to suggest the existence of stimulated emission in a paper published
3、in 1917. However, for many years, physicists thought that atoms and molecules always were much more likely to emit light spontaneously and that stimulated emission thus always would be much weaker. It was not until after the Second World War that physicists began trying to make stimulated emission d
4、ominate. They sought ways by which one atom or molecule could stimulate many others to emit light, amplifying it to much higher powers.The first to succeed was Charles H. Townes, then at Columbia University in New York. Instead of working with light, however, he worked with microwaves, which have a
5、much longer wavelength, and built a device he called a “maser“, for Microwave Amplification by the Stimulated Emission of Radiation. Although he thought of the key idea in 1951, the first maser was not completed until a couple of years later. Before long, many other physicists were building masers a
6、nd trying to discover how to produce stimulated mission at even shorter wavelengths.The key concepts emerged about 1957. Townes and Arthur Schawlow, then at Bell Telephone Laboratories, wrote a long paper outlining the conditions needed to amplify stimulated emission of visible light waves. At about
7、 the same time, similar ideas crystallized in the mind of Gordon Gould, then a 37-year-old graduate student at Columbia, who wrote them down in a series of notebooks. Townes and Schawlow published their ideas in a scientific journal, Physical Review Letters, but Gould filed a patent application. Som

Before
24、 journalists could reach the town, Wang was operating like a one-man news agency, jotting down what he saw with his phone and digital camera.

Despite its fast growth over t
39、he past three decades, China remains a developing economy. Economists have so far described Chinas overtaking of Japan as “just symbolic“.Early Monday, the Japanese government estimated its gross domestic product (GDP) at $1.286 trillion (8.74 trillion yuan) in the April-to-June quarter, compared to
40、 Chinas $1. 335 trillion.China has surpassed Japan in quarterly GDP figures before, but this time it is unlikely to be a temporary switch. China is growing at about 10 percent a year, while Japan is forecast to grow at 2 to 3 percent this year.Despite emerging as an economic power, China remains far
41、 behind many countries if per capita GDP is taken into account.In 2009, China reported a per capita GDP of $3, 687, as compared to $ 37,800 for Japan and $ 46,436 for the U. SAs a result, Kyohei Morita, chief economist at Barclays Capital in Tokyo, described Chinas overtaking of Japan as “Just symbo
42、lic-nothing more than that.“Commenting on the situation, a New York Times report said China is “a country burdened with a fifth of the worlds population and insufficient resources. Its per capita income is more on a par with those of impoverished nations like Algeria and Albania.“Cui Peng at CBN Wee
43、kly wrote that “theres no reason to get excited just because China has surpassed Japan in GDP“. By way of explanation, he compared GDP to a companys turnover.“A high turnover doesnt always bring high profits; the high costs behind the turnover might make the company lose money,“ he explained.Also, C
44、hina is still facing domestic problems like poverty and a widening wealth gap.“China is a developing country. The quality of Chinas economic development still needs to be raised. It needs more effort to improve economic quality and peoples lives,“ said Yao Jian, Commerce Ministry spokesman, on Tuesd

It was the governments first public reaction to the news.（分数：4.00）(1).Why have economists described Chinas overtaking of Japan as “just symbolic“?（分数：1.00）A.Because according to GDP, China is still behind the U. SB.Because China reported a per capita GDP of $ 3,687 in 2009.C.Because China has be
