1 The elephant that came from Africa is now used__the weather in the northA for B to C at D with2 Mary worked very hard,her boss made her__all the rooms in the house all day long.A clean B cleaning C to clean D cleaning3 He wanted to travel to Europe
1 The elephant that came from Africa is now used_B_the weather in the north
A for B to C at D with
be used to 适应了...；习惯了...
2 Mary worked very hard,her boss made her_A_all the rooms in the house all day long.
A clean B cleaning C to clean D cleaning
make sb.do sth,make是使役动词后应加动词原形````与它用法一样的是let.但如果是被动,则变为be made to do sth .所以这里选A
3 He wanted to travel to Europe when he finished__his second novel.
A to write B write C had written D writing
选D
finish doing sth 完成某事
而且这里是用现在时表示将来发生的事,这是英文的说话习惯
4 Since he said so,I_D_him.
A have believed B will have believed C must believe D have to believe
因为他这么说了,我不得不相信他了.
have to 不得不.只有D最合适.C must 表示需要做什么,但是是出于自身的原因；而have to 是由于外在的原因而不得不做什么事
5 Be quiet,I can't hear a sound.There_C_anybody else in the hall.
A mustn't be B can't be C shouldn't be D couldn't be
shouldn't 表示“本不该如何如何”.“安静点,我都听不到音乐了,本来不应该有其他人来这个礼堂的”
6 listen to the music.Someone_C_CD next door.
A must play B should play C must be playing D can be playing
“肯定是有人在放CD”,这里表示很肯定的推测语气,而且让别人去听,所以事情正在发生,所以选C
