科目:初中英語(yǔ) 來(lái)源:2012-2013學(xué)年浙江省桐鄉(xiāng)市九年級(jí)文理聯(lián)賽模擬英語(yǔ)試卷(解析版) 題型:閱讀理解
Air is a colorless, tasteless and invisible(看不見(jiàn)的)gas that is around us. An “empty” drinking glass and an “empty” room, in fact, are not really empty. Each is filled with air. When the glass is filled with water, the water pushes the air out of the glass.
Air, as a gas, has no definite shape, but because it is matter, it takes up space and it has weight. It is easy to prove that air is something that takes up space. Stuff a piece of dry cloth(布)into the bottom of a glass so that it will not fall out when the glass is turned upside down. Push the upside down glass, holding straight up and down, into a jar of water till the glass is completely covered. When the glass is taken out of the water, the cloth is still dry. The air inside the glass shows that it takes up space and keeps the water from coming in.
1.Since air is matter, it has ________.
A.room , and weight as well B.both room and shape
C.either room or weight D.neither shape nor weight
2.The word “Stuff” means ______ in Chinese.
A.撕 B.蓋 C.取掉 D.塞
3.The writer tells that the experiment(實(shí)驗(yàn))___________.
A.is carried out in the space B.must be done in the lab
C.is made in the room D.can only be done in the open air

閱讀下面短文,根據(jù)短文內(nèi)容回答問(wèn)題。
Recently, more and more people pay attention to eating healthily. Some food additives(添加劑) are used to make different kinds of foods. Some of them can make the food more delicious and some of them can make it colorful. But lots of chemicals are used to produce what we eat every day.
Sudan red is a kind of chemical that factories used it to dye cloth, make the shoes brighter. But some people produced salted duck eggs with it . However, it isn’t a kind of food additive. The food made from Sudan red makes it easier to cause cancer. Melamine(三聚氰胺) is another kind of chemical that are banned(禁止). It’s white crystal(晶體), which was discovered by a German chemist called Sustus Von Liebig in 1834. Melamine can be used to make paper, medicine and woods, ect. But nobody can imagine that some people used it as a material of milk powder(粉末). Because of melamine, it’s reported that 4 babies died and more than 50 thousand babies are affected since 2008. Sanlu, a famous milk powder factory was closed. What’s worse, milk powder with melamine appeared in 2011 again. Problems of food safety, for example, poisonous rice, lean meat powder(瘦肉精) and plasticizers(塑化劑) are becoming more and more serious.
Fortunately, lots of laws have been made to make the solution(解決方法) better. We think we will eat more healthily in the future.
1.Can the food additives make the food colorful and more delicious?
2.What is Sudan red?
3. When was melamine discovered?
4.請(qǐng)將劃線句子翻譯成漢語(yǔ)。
5.為了保證食品安全,避免類似事件發(fā)生,請(qǐng)你用英語(yǔ)給負(fù)責(zé)食品安全的相關(guān)部門提出建議(只需一條即可)。
