【題目】—Molly has changed so much! She ________ be shy and quiet.

—Yeah. But now she________ speaking in front of class.

A.is used to; is used toB.used to; is used to

C.used to; used toD.is used to; used to

【答案】B

【解析】

句意：——Molly變了好多！她以前靦腆又文靜�！堑�。但是現(xiàn)在她習(xí)慣了在全班同學(xué)面前發(fā)言。

考查used的慣用法。is used to to為介詞，意為“習(xí)慣做”；used to 過去常�！�。used to do sth. 意為“過去常常做某事”；be used to doing sth. 意為“習(xí)慣做某事”。根據(jù)標(biāo)志詞But now可知，前一句說的是過去的情況，后一句說的是當(dāng)下的情況。故選B。

【題目】 Every day, the world uses about a thousand million tons of water. Water is a human right and everyone should have their share. Yet more than 700 million people around the world have trouble getting clean, safe water.

Treating（處理）wastewater is a good way to provide fresh water for us. And it also helps the environment by keeping waste out of rivers and oceans. 80% of wastewater around the world is not treated at all, and it is running into oceans. But now we have got the technology to treat and reuse the wastewater.

While 75% of our planet is covered with water, only 2% is fresh water—that comes from rivers, lakes, ice and snow. The rest, 98% of the water, is in seas and oceans. It is too salty to drink. Then desalination businesses come in. More than 19,000 factories have been built around the world, mostly in coastal（海岸的）countries. They process（加工）more than 92 million tons of salty water every day. But the technology they use requires a lot of energy.

Scientists are working to create a less costly technology. They want to produce 20 times more clean water and make sure everyone has enough. But for now, the world still faces each day with not having enough water for everyone.

A.By letting waste run into oceans and rivers.

A.遠(yuǎn)洋運(yùn)輸B.潮汐發(fā)電

C.海水淡化D.食鹽銷售

【4】At present, the technology to process water .

A.causes pollutionB.saves much water

C.wastes much moneyD.needs much energy

【5】What can we know about from the passage?

A.Thanks to the technology, people have enough clean water now.

B.75% of our planet is covered with water, and most is fresh water.

C.Though we have tried many ways, water problem is still serious.

【題目】 English playwright Arthur Wing Pinero said, “Where there’s tea, there’s hope.” Similarly, a Chinese saying goes that “Firewood, rice, cooking oil, salt, sauce, vinegar and tea are the seven necessities to begin a day.”

Tea is, without doubt, welcomed all over the world. According to Statista, a German website for statistics(數(shù)據(jù)）, global tea production reached about 5.8 million tons in 2018. It has become the most consumed beverage(飲品） in the world – after water, of course.

According to the UN, tea is much more than just a hot drink. It’s a big part of many cultures around the world. You probably know that people in China use top-grade tea to show respect when receiving important guests. Meanwhile, the British tradition of afternoon tea is an important part of that country’s identity. Making Malaysia’s pulled tea has become a sort of art form, where drinkers take pride in its entertainment aspects.

Apart from its cultural significance（意義）, tea is also a medicine, used from ancient times to modern day. “Tea is cold and lowers the fire,” Chinese Ming Dynasty herbalist Li Shizhen once said. The health benefits of tea are still being discovered today: preventing heart disease, obesity and cancer have all been linked to drinking green tea, according to the National Center for Biotechnology Information in the US.

Hot or cold, bagged or loose-leaf, tea is more than a drink – it’s a social custom and also a magic medicine, a link to the past and a way of life. (改編自 21 世紀(jì)英語網(wǎng)站）
