I am writing in the hope that I may obtain an opportunity to further my study in Applied Physics toward master degree in your unversity.
My name is Li Jin, an undergraduate student of the Department of Applied Physics, Tsinghua University(China). Next year in the summer, I will graduate and get my BS degree. I plan to continue my study and research in this field under the insructions of first-class professors and in a dynamic academic atmosphere. I chose Boston University because there are a congenial team of researchers, an array of databases and research projects in your School of Physics. I believe my interests are extremely congruent with the strengths of the School. And my solid academic background will meet your general entrance requirements for graduate study.
I will appreciate it very much if you could send me the Graduate Application Forms, the Application Form for Scholarships/Assistantships, a detailed introduction to the School of Physics, and other relevant information. My mailing address is shown on the top of this letter.
I am looking forward to hearing from you soon. Sincerely yours, Li Jin
part 2環境保護
大氣汙染：關鍵詞：sulfur dioxide(二氧化硫，一氧化碳)
Although substantial progress had been made, sulfur dioxide and monoxide levels were up 25 percent nationally and particulates were increased by more than 14 percent. What is more, pollution levels in a dozen cities were higher than those of 1970. Of 20,000 major stationary sources of air pollution, about 5,000 failed to meet the schedules, and well over half the steel plants and nonferrous smelters in the United States continued to be in violation of federal regulations.
核汙染(Chernobyl: 切爾諾貝利核事故)
On April 26, 1986, another serious incident alarmed the world. One of four nuclear reactors at Chernobyl', about 130 km (about 80 mi) north of Kyiv (now in Ukraine) in the USSR, exploded and burned. Radioactive material spread over Scandinavia and northern Europe, as discovered by Swedish observers on April 28. According to the official report issued in August, the accident was caused by unauthorized testing of the reactor by its operators. Radiation about 50 times higher than that at Three Mile Island exposed people nearest the reactor, and a cloud of radioactive fallout spread westward. Unlike most reactors in western countries, including the United States, the reactor at Chernobyl' did not have a containment building. Such a structure could have prevented material from leaving the reactor site.
動物保護(關鍵詞：bald eagles, wildcats, buffalos)
More animals have been found on the verge of extinction. Recently, the Federal Government has put wild cats, bald eagles on the list. And buffalos had almost been erased from the American continent.
沉迷網路(關鍵詞：boost self-confidence增強自信, take refuge：逃避現實，stress:壓力，withdraw: 離群
According to psychologists, many young people suffering from shyness also risk becoming addicted to computers. Success with computers provides them with the self-confidence they lack in their personal lives. Zimbardo fears that shy youngsters who take refuge in the computer may fail to learn and practice important social skills needed later in life.
盜版產品(safeguard intellectual property，CD, videos, CD-ROMs, counterfeit trademarks)
In March, China and the United States averted a trade war when they reached an agreement to safeguard U.S. intellectual property rights and ban the sale of pirated compact disks, videos, CD-ROMs, and counterfeit trademark goods including jeans, jackets and T-shirts. .
交通堵塞(關鍵詞：Tokyo, narrow lanes, radiating highways, overcrowded, parking, blaring vehicles.)
Much of the street pattern of Tokyo dates to historic times and is made of narrow, crooked lanes that are unsuitable for heavy use by automobiles. The radiating highways and expressways that were put in to modernize the road network are usually badly overcrowded, and traffic moves at a slow pace. Parking is a major problem. A person must provide proof of an off-street, overnight parking space to own a car in Tokyo.
