题目内容

【题目】—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变了好多！她以前腼腆又文静。——是的。但是现在她习惯了在全班同学面前发言。

考查used的惯用法。is used to to为介词，意为“习惯做”；used to 过去常常……。used to do sth. 意为“过去常常做某事”；be used to doing sth. 意为“习惯做某事”。根据标志词But now可知，前一句说的是过去的情况，后一句说的是当下的情况。故选B。

【题目】 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（处理）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.

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.

【题目】 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(数据）, global tea production reached about 5.8 million tons in 2018. It has become the most consumed beverage(饮品） 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（意义）, 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. (改编自 21 世纪英语网站）
