10．instead与instead of
（1）作为副词，instead的含意是“代替，顶替”，表⽰前⾯的事情没做，⽽是做了后⾯的事。

如：
He wanted to be a great singer, but he became a doctor instead.他想当名歌唱家，但他却成了⼀名医⽣。

（2）instead of是介词词组，后接⼀个并列成分，可能是名词、代词、介词短语、副词等。

接动词时，应该⽤-ing形式。

instead of短语具有否定意义，后⾯跟没有做的事情。

如：
He answered this question instead of that.他没回答那个问题，⽽是回答了这个问题。

11．a number of与the number of
（1）a number of意为“⼤量的”、“许多的”，后接复数名词，作主语时谓语动词⽤复数形式。

如：
A number of books were stolen from the library.图书馆遗失了很多书。

（2）the number of意为“……的数量”，作主语时谓语动词总是⽤单数形式。

如：
The number of students in our school is about two thousand.我们学校的学⽣⼈数⼤约是两千。

⼆、例句解析
1．What should I get my mom for her birthday?我应该为我妈妈的⽣⽇买点什么礼物呢？
（1）句中should为情态动词，意为“应该”、“应当”，其后接动词原形，⽤于各种⼈称和数。

如：
You should finish your work first.你应该先完成⼯作。

2．－How about a scarf? / －No, that's too boring.
（1）How about意思是“……怎么样”，具体含义要紧扣上⽂去理解。

也可以说What about。

值得注意的是about是介词，所以其后只能接名词、代词、动名词等具有名词性质的词。

如：
－When shall we meet tomorrow? －How about 8∶00?⼋点钟怎么样？
3．What's the best gift Joe has ever received?乔曾经得到的最好的礼物是什么？
句⼦中Joe has ever received是⼀个定语从句，修饰the best gift。

该从句⽤现在完成时，表⽰“到⽬前为⽌乔得到过的（礼物）”。

如：
This is the most boring film I've ever seen.这是我曾经看过的最乏味的⼀部电影。

4．Dogs are too difficult to take care of.狗太难照料了。

（1）too＋形容词或副词＋to＋动词原形，意为“太……⽽不能……”。

如：
You speak too fast to be followed.你讲话太快了，以致让⼈跟不上（听不懂）。

（2）take care of意为“照顾，照料”，与look after意思相当。

表⽰“照顾好”则说take good care of。

如：Please take good care of your sister.请照看好你妹妹。

5．enough作名词时，表⽰“⾜够的⼈或物”，代替可数名词或不可数名词；enough⽤形容词时，表⽰“⾜够的”，修饰名词作定语，放在名词前；enough 作副词修饰形容词、副词等时，放在它所修饰的词的后⾯。

常⽤的句型是；形容词／副词＋enough to do sth．意思是“⾜够……于某事”。

My brother is old enough to go to work on farm.
My sister is too young to go to school
6.However，life with a pig isn’t always perfect.不管怎样和猪⼀起⽣活总不是完美的。

▲however这是⼀个合成词，“⽆论如何”，“不管怎样”，仍是⼀个副词，⽤来强调句⼦的语⽓。

⼀般⽤做插⼊语，放在句⾸。

如：
However，I must go back today.我今天⽆论如何要回去。

However hard he tried，he didn’t catch up with the bus.
⽆论他怎样努⼒，他还是没能赶上车。

Whenever you come，we will welcome you.⽆论你什么时候来，我们都欢迎你。

⽆论我们来⾃何⽅，我们都应该成为好朋友。

8.辨析：some time，some times，sometime与sometimes
①some time⼀些（点）时间。

此时time为不可数名词“时间”。

Don’t worry，there is some time.（⼀般⽤a little time）
②some times⼏次，⼏倍。

这⼉time为可数名词“次”，“倍”。

The number of the students in our school is some times over that in theirs.
③sometime adv.（将来）某个时候。

I believe they will come sometime.我相信他们不定什么时候能来。

We will go to plant trees sometime next week我们下周某个时候要去植树。

④sometimes adv.有时候，多⽤于⼀般现在时。

My father sometimes comes back from work very late.
9.fell为动词fall的过去式。

fall asleep意为“睡着、⼩睡”。

例如：I fell asleep while watching TV．我在看电视时睡着了。

asleep形容词。

意为“睡着的”，以a-起⾸的形容词在句中只能作表语，不能放在名词前作定语。

例如：Is he sleeping? 他正在睡觉吗？
Yes，he is asleep．是的，他睡着了。

The baby is asleep in the bed.婴⼉在床上睡觉了。

sleeping呵作为“睡眠中的”，⽤在名词前作定语。

例如：a sleeping dog．⼀只熟睡的狗。

10．Have you ever been to an amusement park?你曾去过娱乐圈吗？
Have you ever been to…?意为“你曾去过……吗？”，其中have been to属现在完成时的⼀种⽤法。

ever⽤于疑问句中，表⽰“曾经”，常与现在完成时连⽤。

如：Have you ever been to Wuhan?你曾到过武汉吗？
Have you ever spoken to a foreigner?你曾和外国⼈谈过话吗？
⼆、重点句型：
表⽰提建议的句⼦
Why don't you…?＝Why not…?你为什么不……呢？如：
Why don't you /Why not get a computer?你为什么不买台电脑呢？
How about…?＝What about…?……如何？……怎么样？后⾯跟sth.或doing sth.。

如：
How about /What about a dress?⼀条裙⼦怎么样？
