However, many advantages the industrial society brings us also have a down side. One of the adverse effects of industrialization is acid deposition due to power plants, fossil fuels and automobile emissions. Acid rain is the popular term but the scientists prefer the term acid deposition. Acid rain can have adverse effects on the environment by damaging forests and lakes, making it too difficult for many plants and animals to live.
Charles Angus Smith, an Englishman, was the first to suggest, in 1852, that sulfuric acid in Manchester, England, was causing metal to rust and dyed goods to fade. One source that causes acid rain is fossil fuel. This energy source contributes 23.1 million tons of sulfur dioxide and 20.5 million tons of nitrogen oxides to our atmosphere worldwide. When fossil fuels are ignited, such as oil and coal, they release carbon dioxide, a so-called greenhouse gas that traps heat within the earth's atmosphere, which causes global warming. Also, they release sulfur dioxide, nitrogen oxide and metals such as mercury, aluminum into the atmosphere, which later can be carried a long distance from their source and be deposited as acid rain.
Forests are a complex ecosystem that involves trees, soil, water, the air, climate and other living organisms that support the community of wildlife: animals, birds, insects and plants. The countries most affected by acid rain are in Europe. Central Europe faces a much greater threat since it has a large amount of forest area and about 8% of German's forest face the lethal effect of acid rain. Acid rain kills about 50 million hectares of forest. Acid rain does not kill trees outright but weakens them to the point where they become susceptible to extremes of heat or cold, attacks from blight-causing or from inserts, and other environmental stresses.
When acid rain falls into lakes and rivers, it destroys all living things and populations of fish, aquatic plant life and microorganisms decline. Fish just goes extinct because they simply fail to reproduce and become less and less abundant, until they die out.
The result of acid rain is not only the destruction of forests and lakes, but also the corrosion of buildings and monuments. Almost every building of a major urban or industrial centre may be at risk from the corrosive effects of acid deposition and the rate of corrosion has increased dramatically in many urban areas. The Athenian monuments have got worst in the past 20～25 years as a result of pollution. Acid attack can also lead to stone decay through the creation of salt, which can crystallize and force apart mineral grains, causing the stone to disintegrate.
As our society gets more advanced, there is also the rising effect of pollution. To stop the effect we need to find alternative ways to remove or replace fossil fuel that is responsible for acid rain. The government needs to put stricter laws on the industries that pollute. People should find an efficient and alternative way to stop the pollution, because the effects of acid rain can be seen all round us, starling with forests and lakes, and in the heart of a city where the buildings and monuments are being eaten away by pollution.
According to the passage, acid rain is ______.
A．a source of pollution
B．an effect of industrialization
C．an advantage of industrial society
D．a deposition of fossil fuels
A．the growing seriousness of the pollution
B．the alarming effect of increased pollution
C．the result of the air pollution caused by acid rain

听力原文： Official Iranian news agency quoting a senior Foreign Ministry official has said preparations were being made for the Foreign Minister Dr. Ali-Ahbar Veliatti to visit Iraq.

In an interview carried on Teheran Radio, Ali Korum said an Iraqi delegation will be traveling to Teheran shortly to follow up on the talks.

M: Yeah, I' m going to discuss robots.
W: Robots？ You mean those machines that walk and talk like in the movies？
M: No, industrial robots like those used in the automobile and electronic industries.
W: I saw an article about that kind of robot the other day. There were pictures of robots welding cars, but they certainly didn’t look the way I thought robots should look.
M: The robots we usually imagine are made up in science fiction. In industry, robots are designed to do a specific set of operations, such as welding car frames. They are rarely built to resemble humans.
W: Actually, all they need is a kind of brain to give signals, and a mechanism, such as an arm, to carry out instructions, right？
M: Right. Tiny computers become the brain of these robots. The computer sends signals, in the form. of electronical impulses, and move an arm and a claw. The claw is the hand that does particular kinds of work.
W: OK. But we' ye had machines on assembly lines doing work for people for years. That’s what started the industrial revolution, remember？
M: But each of those machines can only perform. a single operation and it takes months to modify them. The new industrial robots can each do a number of tasks. And it’s easy to reprogram them to perform. totally different operations. That’s one reason why they're becoming so popular.
W: They increase productivity too, don't they？ I read that even though they're still quite expensive, they often cost less per year than a worker doing the same job. I imagine robots will be used more and more.
M: Exactly. So now that you know all about the next industrial revolution, you don’t have to come to Speech Club tonight.
What kind of robots does the man refer to？
A．Agricultural robots.
B．Industrial robots.
C．Computers.
D．Electrical robots.

听力原文： When John Milton, writer of Paradise Lost, entered Cambridge University in 1625, he was already skilled in Latin after seven years of studying it as his second language at St. Paul’s school, London. Like all English boys who prepared for college in grammar school, he had learned not only to read Latin but also to speak and write it fluently and correctly, His pronunciation of Latin was English, however, and seemed to have sounded strange to his friends when he later visited Italy.
Schoolboys gained their skill in Latin the hard way. They memorized rules to make learning by heart easier. They first made a word-for-word translation and then an idiomatic translation into English. As they increased their skill, they translated their English back into Latin without referring to the book and then compared their translation with the original. The school master was always at hand to encourage them. All. schoolmasters believed Latin should be beaten in.
After several years of study, the boys began to write compositions in imitation of the Latin writers they read. And as they began to read Latin poems, they began to write poems in Latin. Because Milton was already a poet at ten, his poems were much better than those painfully put together by other boys. During the seven years Milton spent at the university, he made constant use of his command of Latin. He wrote some excellent Latin poems which he published among his works in 1645.
Which of the following is the best title for the passage？
A．How John Milton Wrote Paradise Lost.
B．How John Milton Became a Poet.
C．How John Milton Studied Latin.
D．How John Milton Became Famous.
A．It had a strange accent.
B．It was difficult to understand.
C．It had a strong Italian accent.
D．It was easy to understand.
