短文填空
Before Einstein，scientists believed that light travelled through
space in a straight line.But Einstein was able to prove that light
coming from the stars were bent as it passed the sun.As aresult，
it appeared to scientists on earth that the stars had moved.He
worked out just how much the light would be bent；he could also
work out how far the stars would appear to have moved.His
discovery was completely new；it was said that only three people
could understand it at that time.The difficulty was how he could
prove his ideas to other scientists.

疑难语句细解

few days.

【要点指南】 此处Worried about the journey是形容词短
语作原因状语，相当于从句Because I was worried about
the journey。形容词短语作原因状语时，通常放在句首。

well.

and a table and some chairs rose from under the floor as

来。
【要点指南】 句中的as if by magic是as if they were raised
by magic的省略形式。as if是连词，一般引出方式状语从
句，但如果主句的主语与从句的主语一致时，从句常省略
主语和谓语，特别是从句的谓语含有be动词时，因此也可
以说as if后可接介词短语、动词不定式、现在分词或过去
分词等。
He glanced about as if (he was) in search of something.
他扫视着四周，像是在找什么东西似的。
He shook his head as if (he wanted) to say “no”．
