Humankind has tried to improve its standard of living since the very beginning of civilization. Back then, as well as today, providing food and security was the basic task for a person. However, nowadays the range of required goods has expanded significantly. People feel the need for not only some primary things, such as a piece of bread and a roof over their heads, but also for various facilities and luxuries. Providing humanity with these things is connected to the use of natural resources, which requires energy. In turn, the common sources of energy we use today cause pollution, so economic growth is almost inevitably associated with environmental damage.

Economic growth is the increase in numbers of goods and services produced over time by an economy, and it's calculated in terms of real Gross Domestic Product (GDP). Before growth is calculated, inflation(通货膨胀) is adjusted in order to take into account its misleading effect on the price of goods and services. Economic growth can also be explained as the increase in expected output, which results from an increase in actual output, or total demand.

There are certain aspects of economic growth which affect the environment. The first of these is the fact that in order to produce more goods and products, at a faster rate, the construction of large industrial plants is required. These plants produce a lot of waste, leading to the pollution of water and the atmosphere, which may cause negative long- term health effects to nearby populations of animals, or people. They also lead to global warming.

Industrial manufacturing leads to the constantly increasing energy consumption. The traditional energy sources, which are commonly used nowadays, are considered to be the greatest polluters to the environment. There also exist so-called eco-friendly sources of energy. They are sometimes preferred but replacing the traditional sources with them also requires time, during which people have to make some sacrifices to support these undertakings.

In order to produce economically practical energy, a sometimes significant transformation of the natural site is often inevitable. This is expensive and, has harmful effects on the environment. Application of wind energy would Block airflows' natural speed, which is the reason for their decrease in strength, after crossing the windmill. Consequently, the pressure balance that is brought about by this current will be affected, and it is important to remember that the environment and weather conditions are directly affected by atmospheric pressure.

For these reasons, bringing about economic growth without resulting in any environmental damage is impossible.

小题1:What does the passage mainly talk about?

A.Pollution caused by plant construction

B.Effects of windmills on the environment

C.Economic growth and human civilization

D.Economic growth and environmental damage小题2:According to the passage, the author holds the opinion that ____.

A.economic growth should be calculated in terms of GDP

B.use of natural resources causes no damage to the environment

C.industrial manufacturing may cause damage to the environment

D.a windmill is a perfect way to produce economically practical energy小题3:Which of the following shows the structure of the passage?

CP (Central Point)     P (Point)      Sp (Sub-point次要点)    C (Conclusion)

题型:单项选择题

文章Ⅲ 電車の中に立っている乗客が何か紙切れのようなものを広い、落とし主に渡したらしい。 こちらからは見えなかったが、受け取った人が「アリガト」といった。口の聞き方は男みたいだが、声は女性である。おやと思って、そちらへ目を向ける。56見たところではどちらとも決めかねる。こういう時、髪型で判断できることが多いが、この人は両性的なスタイルだ。決め手は声だけか。それで、いつかイタリア料理のレストランであったことを思い出した。そこは男性トイレがへやの左側、女性用は反対の右側にある。男性風の客が右の女性トイレへ入っていこうとした。見ていた店の女主人が後姿に向かって57「そちらは…」といいかけた。客が「え?」と聞き返す。女の声だ。店の人は慌てて「あっ、いいです」と言った。この客、後姿はもちろん、前から見ても男そっくりで、勘違いされてもしかたないと店の人に同情した。さっきの電車の乗客は「アリガト」の58男みたいな調子と女の声がじっくりしないので、気になったのである。この頃、男女の言葉の違いが少なくなってきた。女言葉があるのはおかしいとはっきり言う人もいる。わざと乱暴な言葉を使っているらしい女子高校生は別として、若い女の人がごく自然に「…したんだ」、「…なあ」と言う。それに周りもそれほど驚かなくなった。小説の中で男女2人の会話なら、いちいち話し手を示さなくても、言葉づかいでどちらが話しているのかがわかる。こういう手もだんだん通じなくなるだろう。メーキャップすれば、見た目はかなりごまかせる。テレビで時代劇に出てきたタレントが現代劇に登場すると、同じ人とは思えないことがある。59そういうときも声が結び付けてくれる。声はメーキャップできない。男女の区別は、声が一番確かな手がかりだと考えてきたが、この頃、男のような電話の声の女の人がちょいちょいいる。 注:メーキャップ/化粧。タレント/演员。問題

本文によると、男言葉、女言葉の使いわけはどんなときに役に立つのか。

A.女性は社会人になると、乱暴な男言葉を使わなくなるので、高校生か社会人か区別できる。

B.電話で男のような声の女性も、言葉づかいで女性だとわかる。

C.小説の中の会話で、男が言ったのか女が言ったのか書かなくても区別できる。

D.女言葉があるのは不合理だし、何の役に立たない。
