【題目】— Do you know each other?

— Of course. We________friends for almost twenty years!

A.areB.wereC.have beenD.be

【答案】C

【解析】

句意:——你們認(rèn)識嗎?——當(dāng)然。我們做朋友快二十年了!

考查動詞時態(tài)。are一般現(xiàn)在時;were一般過去時;have been現(xiàn)在完成時!for+時間段”表示做某事做了多長時間,時態(tài)使用一般過去時或用現(xiàn)在完成時。一般過去時表示過去某個時間里發(fā)生的動作或狀態(tài),與現(xiàn)在毫無關(guān)系;現(xiàn)在完成時動作(瞬間動詞)發(fā)生在過去,對現(xiàn)在有影響或結(jié)果,或動作(延續(xù)性動詞)發(fā)生在過去,且一直持續(xù)到現(xiàn)在。根據(jù)“for almost twenty years”和語境(20年前認(rèn)識一直持續(xù)到現(xiàn)在)可知此句時態(tài)是現(xiàn)在完成時;故選C。

【題目】 Astronauts (宇航員) have very busy lives. Each day they are carefully planned by mission (任務(wù)) control. The 12-hour working day on the International Space Station (ISS) begins with a wake-up call. After a quick wash with a wet cloth, the crew (全體乘務(wù)員) have breakfast and run through the jobs for the day.

Space stations are like large houses that need much care and attention. Much of the crew’s time is spent preparing and carrying out scientific experiments.

At least two hours each day is spent on exercise. It is necessary to keep the crew healthy. In some ways, living in a space station is like being on a deserted island. A crew of two or three astronauts has to survive far from home for weeks or months.

If their mission is to be a success, they have to learn to live and work together as a team. Crew members have to learn to share jobs, such as cleaning and repairs. They also have to talk about problems and discuss how to deal with them.

Astronauts first feel the influence of weightlessness (失重) when the rocket engines are turned off. Straight away, they begin to float (漂浮), held down only by seat belts. Weightlessness allows astronauts to appear. superhuman strength. They can lift objects that would be far too heavy to move on the earth.

Without the influence of gravity (重力), astronauts become weak. To stay fit, they have to exercise several hours each day. In a space station, there is no up or down. There is no difference between a floor and a ceiling (天花板). This can make astronauts feel sick until they get used to this strange environment.

根據(jù)短文內(nèi)容,從A、B、C、D四個選項中選擇一個最佳答案。

【題目】 It has been nearly two months since the first case of novel coronavirus was found in Wuhan. As most people stay at home and many industries delay(延遲) their work, some people worry that this might affect China’s economy.

As China Daily reported, the epidemic has directly harmed some of China’s main industries. For example, the tourism industry has been affected, as some foreign countries have set restrictions(限制) to people traveling from China and many airlines have canceled flights to and from China. Also, since many Chinese factories, such as those that make car parts, have delayed their work, companies that rely on their products have been affected as well.

“Despite the temporary(臨時的) influence on the Chinese economy, the outbreak won’t affect the economy’s mid-to long-term fundamentals(基礎(chǔ)),” said Tang Jianwei, chief researcher at the Financial Research Center of the Bank of Communications.

China is making efforts to step up production and resume(恢復(fù)) work. As of Feb 10, 94.6 percent of food-producing and processing(加工) companies in China had resumed work, according to Cong Liang, secretary-general of the National Development and Reform Commission.

Moreover, the digital(數(shù)字的) economy is becoming more active. As people are unable to go outdoors, they are turning to digital entertainment by watching films and TV shows online.
