6. manage to do sth
manage to do sth.暗含succeed in doing sth.之意,指"(经过努力和克服困难之后)将某事做成",即经过努力达到了目的,重点在于结果,后接动词不定式,没有manage doing的用法。 manage to do=try to do sth sucessfully 试发成功做某事 。
7. at a time
作"一次,每次"讲,常用于"数词+at a time"的结构中。
例:Enter two at a time.每次进来两人。
He checked them off one at a time as they came in.。他们进来时,他一个一个地核对。
二、语法精讲
1. 疑问词+动词不定式的用法
1).疑问词+不定式结构中的疑问词,包括疑问代词who, what, which和疑问副词how, when, where等.这些疑问词和不定式一起构成了不定式短语,这种结构可在句子中作主语、宾语、表语等.例句:
How to do it is a question.
该怎样做倒是一个问题。(作主语)
I really don't know what to write about.
我实在不知道该写些什么。(作动词宾语)
We must first solve the problem of whom to serve.
我们必须首先解决为谁服务的问题。(作介词宾语)
The question is where to put it.
问题是该把它放在哪儿才好。(作表语)
I asked him how to learn English.
我问他如何学习英语。(作宾语补足语)
2). 疑问词+不定式结构相当于一个名词性从句,常常可用同等成分的从句代替。改写时只需在疑问词后加一适当主语,并将不定式改成适当形式的谓语。上述例句可以分别改写成:
How we should do it is a question.
I really don't know what I should write about.
We must first solve the problem of whom we should serve.
The question is where we should put it.
I asked him how we should learn English.
3).疑问词+不定式结构经常放在tell, show, teach, learn, know, wonder, discuss, remember, forget, find out等动词(词组)之后作宾语。
例句:
The teacher told the students how to do the experiment.
老师教学生如何做实验。(句中 told含有taught的意思)
The young woman doesn't know what to do.
那位年轻女子不知道怎么办。(句中what不能改换成how)
He tells me how to answer all the questions in English.
他告诉我怎样用英语回答所有的问题。(句中的how不能省去)
另外,这种结构可以构成独立问句。
例:What to do 怎么办
How to get rid of the trouble 如何摆脱困境
2. must和have to的用法区别
1). 强调重点不同
两者都表示必须,但must 侧重于说话者的主观看法,认为有必要或有义务去做某事;have to 则重于客观需要,含有不得不或被迫之意。
例:We must go at once. 我们必须马上就走。
If I buy that car, I have to borrow some money. 如果我要买那辆汽车,我得借些钱。
2). 时态形式不同
must 只有现在时一种形式(在宾语从句中可以表示过去),而 have to 则有多种时态形式。
例:She said that she must go with me. 她说她一定要同我一起去。
They have had to buy a car. 他们不得不买了辆小汽车。
3). 非谓语形式不同
have to 可以有分词、动名词、不定式等形式,而 must 则没有这些形式。
例:He only saw her in the evening, having to be away all day. 他整天得外出,只能晚上见她。
I regret to have to trouble you again. 我很抱歉不得不再麻烦你一次。
4). 否定式的意义不同
must 的否定式 mustn't 意为一定不要、不允许;
而 have to 的否定式 don't have to 意为不必(=needn't)。
例:You mustn't tell him about it. 你一定不要告诉他这件事。(可能是秘密)
You don't have to tell him about it. 你不必告诉他这件事。(他可能知道了)

16.答案:B
解析:细节理解题。根据"He owned all that everyone hoped to have. However, he had no friends and he wasn't happy."可知,他拥有每个人都希望拥有的一切,然而,他没有朋友,也不开心,所以这位身材魁梧的人虽然拥有一切,但他感觉不开心。故选B。

解析:推理判断题。根据"He picked up his violin and played as loudly as he could. The music woke up the sleeping people. All of them ran to the safe place quickly."和"The next day, all the people in the town thanked the huge man. He suddenly had more friends than he could count."可知,他拿起小提琴尽可能大声地演奏,音乐把睡着的人吵醒了,他们所有人都迅速跑到了安全的地方。第二天,镇上所有的人都感谢这位身材魁梧的人。他突然有了数不清的朋友。所以可推断出巨人突然有了更多的朋友是因为他及时挽救了人们的生命。故选C。
18.答案:B
