in fact “事實(shí)上”，符合題意。故答案為fact。

【2】句意：然而水母沒有那些身體部位也活得很好。

do為謂語動詞，副詞修飾動詞，故答案為well。

【題目】 If you are in Shanghai and want to throw away a cup of milk tea, be careful. You need to follow these steps: first, pour out any milk tea left into a wet waste bin; second, put the paper wrapper (包裝材料) into a recyclable waste bin; third, throw the single-use cup and straw (吸管) into a dry waste bin.

Sounds complex ? You’ll have to get used to it. From July 1 on, people in Shanghai are required to separate their garbage according to strict rules. Many other cities in China are planning to create similar garbage -separating rules.

Why should we separate our garbage? The answer lies in the increasing of waste we are producing. Chinese cities produce over 200 million tons of waste each year, according to Chinese Economic. Most of this waste is buried (填埋), which may pollute water and soil! In addition, we are running out of space.

In fact, more than half of our waste can be recycled. Recyclable garbage can be made into new materials, while wet garbage can be used to make gas, heat and fertilizer (肥料). So in order to recycle better, we need to separate our garbage.

Can’t garbage-processing companies do the separating job for us? They can. But that requires a lot of work and costs lots of money. Things will become much easier if each of us can separate our own garbage. Besides, the hard task of separating might encourage people to produce less waste. Do you still want to buy that milk tea?

根據(jù)短文內(nèi)容選擇最佳答案。

【1】The underlined phrase “complex” in the passage means “_______” in Chinese.

A.復(fù)雜的B.容易的C.高級的

A.similar garbage-separating rulesB.strict garbage- separating rules

C.old garbage- separating rules

【3】According to the passage we know that recyclable garbage ______.

A.can be used to make gas, heat and fertilizer

B.can be buried

C.can be made into new materials

【4】Which of the following is TRUE according to the passage?

A.The hard task of separating might encourage people to produce more waste.

B.Chinese cities produce over 200 million tons of waste each year.

C.The garbage-processing companies can’t do the separating job for us.

【題目】 Today more and more people want to live in big cities, but what can be done to help them live in crowded cities like Tokyo? Many architects( 建 筑 師 ) are looking for ways to solve this problem. 25-year-old Haseef Rafiei has caught the world’s attention because of his special skyscraper concept(摩天大樓概 念)—“Pod Vending Machine” skyscraper.

Haseef comes from Kuala Lumpur, Malaysia. He is now a student of Manchester School of Architecture. He got his idea form a trip to Japan. He noticed vending machines are popular in Japan. He said, “Vending machines make buying easy and interesting.” After seeing vending machines have made such a difference to people’s lives, Haseef thought, “Why not build skyscrapers that act the same way?”

Haseef’s “Pod Vending Machine” skyscraper can act as a home vending machine. If people want to buy houses in the skyscraper, they can choose the types of pods(吊艙) they’d like to live in and what the inside of the pods looks like. Then the large 3D printer at the top of skyscraper can get the pods printed and then cranes ( 起 重 機(jī) ) can get the pods placed. A smart system inside the skyscraper decides the best place for every pod. If a person doesn’t want to live in his pod any more, the pod will be returned to the 3D printer to get recycled. How amazing it is!

【1】判斷正誤（“T”表示正確，“F”表示錯(cuò)誤）；

A 3D printer at the top of the “Pod Vending Machine”skyscraper can help people print the pods they choose.
