【题目】The new machine, according to the report, will work twice as fast, ______ greatly reducing costs.

A.soB.evenC.yetD.thus

【答案】D

【解析】

考查词语辨析。句意:据介绍,这台新机器的工作速度将是原来的两倍,从而大大降低了成本。A. so因此;B. even甚至;C. yet但是,然而;D. thus因此,从而。根据前后两句的内容可知,前面的新机器工作效率是以前的两倍,导致后面的结果,sothus都有“因此”之意,但so是连词,后面跟句子,而thus是副词,后可以跟动词-ing形式。本句空格后是动词的-ing形式作结果状语,因此要用thus。故选D

【题目】请阅读下面文字, 并按照要求用英语写一篇150词左右的文章。

This week should have seen the beginning of a new semester. Instead, China has been witnessing a different kind of new semester because of the novel coronavirus outbreak. Many Chinese schools have suspended the new semester and moved the classrooms online, leading to an explosion of viewings on online educational platforms,

On the first day of school, DingTalk, a virtual workplace developed by Alibaba Group, held online classes for an estimated 50 million students nationwide, from primary to high school level.

The huge demand led many to assume that online classrooms are the source of future prosperity. But according to a guideline issued by the Ministry of Education on Feb 12, “postponement of school without suspension of learning” is not equal to learning through online courses. As the education authorities have said, it is unnecessary for every teacher to record online courses to be evaluated for quality. Also, kindergarten classes cannot be held online.

【题目】 Pillow fighting in its natural state is a display of chaos, a safe-ish outlet to most children. You grab the nearest pillow and whip it at the nearest body.1

But pillow fighting has been appropriated for high school students as a real sport in Ito, Japan with the set rules. The All-Japan Pillow Fighting Championship consists of two teams of five players each side. Before the match begins, all team members pretend to sleep beneath the quilt on individual futons (垫子).2They cross the dividing line, grabbing a pillow as they go.

3The pillows are thrown, not swung. Any team member struck by a pillow is knocked out of play. A designated player can bring the quilt along and hold it up as a shield for teammates. A second player is appointed "king." When one team strikes the other's king, that team wins the match.

The pillows are designed and produced specially according to strict size and weight regulations. They're filled, not with feathers, but with rubber to achieve the required weight and bounce.4The youngest player so far recorded was 9, the eldest 75.

Two one-minute matches make up a game. As a sport, it's speedy, zany and growing fast. No word yet on its Olympics prospects. But with skateboarding officially in, 5.

E. it is uncertain whether it'll have a promising future
