Question

英语问题请教大家,请帮忙解释下,谢谢!

1.They fulfilled the task assigned by their boss earlier than they (expet)______

2.These are different types of buses(range)___from 11 seats to 44 seats.

3.另外问个问题,during这个单词做句首,句子是否是一般过去时?

Answer 1

1.expected 是过去曾经预期的，所以用一般过去时
2.ranging 动名词做状语
3.during位于句首时，做prep，不能引导从句，意为“在……的时候，在……期间”，后面一般跟一般过去时，因为表示的是已经发生的事情陈述一下。
eg：During the quake they were all self-possessed.
during位于句中时，可以用一般现在时，一般过去时，还可用于祈使句。
eg：I can hit the ball straight during practice。 一般现在时
Several buildings fell during the earthquake。 一般过去时
Wish you peace and happiness during the holidays.祈使句

Answer 2

1 expected
根据前面的fulfilled可知是过去时
不可能是were expected , 首先were 是be动词,而expect也是动词，在句子中不能同时出现两个动词，语法不对
2 ranging
ranging from 11 seats to 44 seats 这半句话是修饰buses的
3 一般来说是这样的，但也要根据具体情况而定

Answer 3

1)were expected. 你要注意他们完成任务不是自己想完成的，是老板要求完成的。所以他们完成的时间比老板所要求的早了一点。本来是the boss expected them to finish the task.但是they finished the task earlier than they were expected by the boss.
2)ranging 主语是buses主动表示这些车有各种各样的位置，从11座的到44座的。
例：
The fire cause 3 deaths,including 2 kids./2 kids included.
3）是。
During the war, many of our villages and towns were burnt down by the invaders。

Answer 4

1.expeted
2.ranged
3.大多数是这样， 根据语气判断是发生在过去就用过去时态
