Question

【題目】 A material is what something is made of. There are 5 basic materials. Most things are made with these materials. Some things are made of metal. Some things are made of glass. Some things are made of wood. Some things are made of cloth. And some things are made of plastic.

There are some other materials. But they are not used as much as these 5 materials.

Let's talk about metal first. Metal is very heavy. And it is very hard and strong. It usually feels cool if you touch it. We use metal to make lots of things. We use it for forks and knives. We use it for keys. We use it for cars. We use it for these things because it is very strong.

Next, let's talk about glass. Glass is very smooth. It feels cool to touch. It is not as heavy as metal. It is hard. But it is not strong. It breaks very easily! Then why do we use it? We use it because it is clear! You can see through glass! That's why we use it for windows. That's also why we use it for glasses.

Now, let's talk about wood. Wood is lighter than metal and glass. It is not as strong as metal. But it is much stronger than glass. We use wood to make lots of things. Things made of wood are usually light and hard and strong. Chairs and tables are made of wood. Pencils are made of wood.

Now let's talk about cloth. Cloth is very light. It is much lighter than wood. And it is very soft. We use cloth to make lots of things. For example, it is used to make clothing. And it is used to make blankets.

Last, let's talk about plastic. Plastic is also very light. But it is different from cloth.

Sometimes it is soft. And sometimes it is hard. Plastic can be used to make thin plastic bags. These are light, soft, and strong. But plastic can also be used to make bicycle helmets. These are light, hard, and strong. A helmet and a bag seem different. But they are both made from plastic.

【1】Which sentence from the passage best describes the main idea?

A."We use cloth to make lots of things.”B."Metal is very heavy."

C."There are 5 basic materials."D."A helmet and a bag seem different."

【2】In Paragraph 5, the passage says, "Wood is lighter than metal and glass." What is the main purpose of this sentence?

A.To explain something.B.To recommend something.

C.To compare something.D.To demonstrate something.

【3】Which material would you use if you wanted to make something that was strong and very light?A.Plastic. B.Wood. C.Metal. D.Glass.

【4】In this passage, the author talks about ______________.

A.hard things first, then soft thingsB.heavy things first, then light things

C.strong things first, then weak thingsD.cool things first, then warm things

Answer 1

【答案】

【1】C

【2】C

【3】A

【4】B

【解析】

本文主要講述了生活中制作東西時(shí)使用得較多的5種基礎(chǔ)材料，并對(duì)他們的用處和優(yōu)缺點(diǎn)進(jìn)行了闡述。

【1】主旨大意題，通看全文可知，全文在討論5種基本的材料的優(yōu)缺點(diǎn)，并且他們可以用來做什么，故選C。

【2】細(xì)節(jié)理解題，Wood is lighter than metal and glass.木材比金屬和玻璃要輕得多。根據(jù)句意可知是把木材的特點(diǎn)與金屬和玻璃的進(jìn)行對(duì)比，故選C。

【3】細(xì)節(jié)理解題，題意為想要輕且堅(jiān)固的材料做東西。Metal is very heavy. And it is very hard and strong. 金屬非常重，并且它是非常硬的、堅(jiān)固的。Glass is very smooth.It is not as heavy as metal. It is hard. But it is not strong.玻璃是很光滑的。它不像金屬那樣重。它較硬但不堅(jiān)固。Wood is lighter than metal and glass. It is not as strong as metal 木材比金屬和玻璃都要輕，但是它不像金屬那么堅(jiān)固。Cloth is very light. And it is very soft. 布料很輕，也很軟。 But plastic can also be used to make bicycle helmets.These are light, soft, and strong但是塑料也能被用來做自行車頭盔，這些都很輕、軟和堅(jiān)固。因此對(duì)比5種材料，只有塑膠符合這些特點(diǎn)。故選A。

【4】細(xì)節(jié)理解題，根據(jù)題意是想知道作者是根據(jù)什么順序來寫的這篇文章。通觀全文可知在討論每種材料的時(shí)候都是按照輕重的順序來寫的。故選B。
