Ladies and gentlemen, I returned to this year in a time machine. In the year 2500, we are able to travel through time to any year in the history of the earth. This year is your last chance your lifestyle to save the earth.
Beginning in the middle of the 20th century, a few people were worried about polluting the earth’s water and air, but most people did not change their way of life. Instead, they continued to pour(倒) dangerous chemical(化學物品) and other waste into lakes and seas, to drive more and more cars and trucks, and to cut down trees.
By the year 2200, the earth’s water was completely polluted. People could no longer drink water, and they had to use other types of liquids(液體). Scientists said that in the future there might be too many people on the earth. But not enough was done.
So by the year 2300, there were so many people that food became scarce. There was no water to grow food and all of the fish in lakes and seas died because of pollution. Terrible wars broke out between the rich and the poor. Scientists were working very hard to find another planet in space where humans could live.
By the year 2400, the air was too polluted for humans to breathe. So we had to leave the earth. But only the rich were able to leave. Where did we go? Nowhere. And everywhere. You see scientists did not find another safe planet, so now we must travel around the universe in our space ships. We are still looking for a place to call our home.
So it is up to you to change history. There is still hope. You must change your lifestyle now, before it is too late.
小題1:Which problem is NOT talked about in Paragraph 2?
A．WaterB．AirC．LifestyleD．Food
小題2: The underlined word ‘scarce’ means ‘______’ in Chinese.

D．We found a new home in another planet by the year 2400.
小題4:What’s the best title of the passage?

試題分析：這篇短文主要以擬人的手法講述了環(huán)境污染的嚴重事實，作者通過時間隧道從2500年穿越回到了20到25世紀的不同時代，并描述了各個不同時代的污染的嚴重性，提醒人類保護環(huán)境，愛護人類自己。
小題1:細節(jié)理解題。根據(jù)短文第二段a few people were worried about polluting the earth’s water and air, but most people did not change their way of life.內(nèi)容可知，本段主要涉及到了空氣質(zhì)量、水資源和人類的生活方式，唯獨沒有提到食物方面的問題，故選D。
小題2:詞義猜測題。根據(jù)本句內(nèi)容So by the year 2300, there were so many people that food became scarce. 可知，本句中包含一短語so...that...，意為截止到2300年，地球上的人類是如此之多以致于食物變得太少。再加上下一句There was no water to grow food，可知食物應(yīng)該是不夠人類吃的，故選C。
小題3:推理判斷題。根據(jù)短文第二段but most people did not change their way of life.可知，A選項表述正確；第三段By the year 2200, the earth’s water was completely polluted. People could no longer drink water,可知，B項的描述也是正確的；第四段all of the fish in lakes and seas died because of pollution. 可知C項內(nèi)容正確；倒數(shù)第二段內(nèi)容說到了2400年，只有富人才有機會離開不適宜人類生存的地球，但是也沒有可以適宜人類其他星球供人類居住，可知D項內(nèi)容不正確；故選D。
小題4:主旨大意題�？v觀全文內(nèi)容可知本文主要描述的就是人類的污染環(huán)境極其嚴重，已經(jīng)嚴重威脅人類的生存，到了非停止不可的地步了，所以A項“停止污染”作為文章標題比較合適，故選A 。

A city in South Korea has added a new attraction to its cultural landscape(景觀)—the world’s first “Toilet Theme Park”. The Restroom Cultural Park in the city of Suwon is proving a huge hit with locals and tourists alike.
The park was built to memorize the former city mayor Sim Jae-duck, known as “Mr. Toilet”. He believed the toilet is a very important place and full of culture. Visitors to the park can enjoy its toilet- bowl- shaped exhibition hall as well as lots of bronze statues(銅像) in all kinds of toilet positions.

It famously hosts the Golden Poop Art Festival- a celebration of one of the calls of nature. The city also lists lots of its own public toilets as tourist attractions on its website. Sim Jae-duck’s toilet-shaped house, now a museum, should be the must-see for enthusiasts. It’s said that Mr. Sim was born in the loo of his mother’s house, so he loved toilets very much.

What is the sky？ Where is it？ How bright is it？ What lies above it？ These questions are difficult to answer, aren’t they？
　　Is the sky blue？ The sky has no color. We know that there is air around the world. When planes fly, they need air to lift their wings. Planes can’t fly very high because the air gets thinner when they go up higher. If we go up about 1,200 kilometers from the earth, we’ll find no air there.
　　When we talk about the sky, we usually mean the atmosphere around the earth. It is like a very thick “cover” over the earth and keeps it warm. Without the “cover”, the earth would be a very cold place and nothing could live on it.
　　Looking up above us, you will see the blue sky with white clouds. It is usually light blue, but the sky would be dark blue if you go to the top of the highest mountains. And you will see fewer clouds between you and the sun.
　　And if you sit in a spaceship high above the earth, there is no air at all. The sky would be so dark that its color would be black.
　　Sometimes the sky doesn’t look blue. When the sun rises and falls, you will see red, orange, and other colors in the sky. These are the most beautiful moments of the day.
　　Now you may understand that we see colors because the air scatters (散射) the sunlight. Light travels through the air. Without air, there would be no light and no colors.
小題1:Planes can’t fly very high because ____________.
A．there is air around the world
B．the air gets thinner when they go up higher
C．it’s warmer in the sky
D．the air gets thicker when they go up higher
小題2:We can see colors of the sky because ____________.
A．the sun rises and falls every day
B．the sky has lots of colors
C．the air scatters the sunlight
D．the sunlight has many colors
小題3:Which of the following is TRUE？
A．There is little air without light and colors in the sky.
B．The sky will look red, orange and other colors at noon.
C．The sky has only one color when the sun rises and falls.
D．The sky is dark blue if you go to the top of the highest mountains.
