三、知识点解析

(1)What do you want to be when you grow up? 你长大后想成为什么?

①这是一个含有时间状语从句的主从复合句。主句含有want to be结构,从句是when引导的时间状语从句。

一般情况下,若主从句的动作均未发生,则主句用一般将来时或主句为祈使句或含有情态动词的句子,从句都用一般现在时代替一般将来时。

I’m going to play basketball when I finish my homework. 我完成作业后,打算去打篮球。

②grow up常用来指人或动物长大、成年或成熟。

She is growing up fast. 她成长得很快

还可以引申为“发展”的意思。

A close friendship gradually grows up between them. 他们之间的友谊日益深厚。

(2)—How are you going to do that? 你打算怎样去做?

—I’m going to practice basketball every day. 我打算每天练习打篮球。

①“be going to+动词原形”在句中作谓语,是一般将来时的一种表达形式,表示主语打算、准备或有信心去做某事,其中going并不表示“去”;

We are going to play tennis this afternoon. 今天下午我们要打网球。 而以前学过的“be going to+表示地点的名词”表示主语打算、准备去某地,其中going表示“去”,to是介词,后跟表示地点的名词。

We are going to Beijing this afternoon. 今天下午我们要去北京。

②practice的用法

名词,练习;训练(通常指经常反复的练习)

Playing the piano well needs more practice. 弹好钢琴需要多练。

动词,常用短语:practice doing sth. 练习做某事

She is practicing singing the new song. 她正在练习唱这首新歌。

③辨析:everyday, every day

everyday adj.每天的,在句中作定语,位于名词前。

This is our everyday homework.这是我们每天的作业。

every day 每天,副词短语,在句中作状语,位于句首或句末。

He reads books every day. 他每天都读书。

(3)Well, I’m going to keep on writing stories, of course. 哦,我当然会继续坚持写故事。

keep on doing sth. 强调反复性和决心,既可接瞬间动作(表示反复),又可接持续动作。

Mr. Wang kept on explaining until the students understood. 王老师反复地解释直到学生们听懂了为止。

(4)My parents want me to be a doctor, but I’m not sure about that. 我的父母想要我成为一名医生,但是我还没有确定。

be sure of/ about意为“确信.... ,对...有把握”。

I’m sure of his honesty. 我肯定他是诚实的。

If you are not sure about the situation in the world , you can read the newspaper every day.

如果你对世界形势不大了解,你可以每天看看报纸。

拓展

be sure to do sth.务必做某事,请一定做某事,(多用于祈使句)

Be sure to telephone me and give me all the news.请一定要给我打电话,让我知道所有的消息。

还可表示一种推断,意为“一定做某事,肯定做某事”

The child is sure to be a teacher. 这孩子一定会成为一名教师。

You are sure to win. 你们肯定会赢。

be sure+从句,确信

I’m not sure whether he will come. 我不确信他是否会来。

(5)Just make sure you try your best. 只要确保你尽力了就行。

make sure意为“确保,查明”,后可接宾语从句,也可接of (doing) sth.结构。

You must make sure of the time and the place.你必须把时间和地点弄清楚。

Make sure at least two people from the marketing team can attend. 要确保销售团队至少有两个人来参加。

(6)Were you able to keep them? 你能履行它们吗?

be able to意为“能够”,后接动词原形,相当于情态动词can。

He was able to/ could speak French very well. 他法语讲得很不错。

辨析:can, be able to

相同点: can与be able to均可表示某人做某事的能力,常可互换。

Please let us know if you cannot/ aren’t able to come. 你若不能来,请通知我们。

不同点:

can只有现在式和过去式(could)两种,用于现在时,can泛指一般的能力;在表示过去的一般能力时,两者没有很大差别。

You can/could do it. 你可以做到。

He can swim. 他会游泳。

I could /was able to play the piano when I was young. 我小的时候就会弹钢琴了。

be able to可根据需要使用多种时态,还可以和一些情态动词连用,或用作动词不定式等非谓语形式。

用于现在时,be able to指具体做某件事的能力:

The baby will be able to walk in a few weeks.这个宝宝再过几个星期就能走路了。

I am able to express my idea in a clear way. 我能清楚地表达自己的想法。

在表示过去的一般能力时,两者没有很大差别。但如果要表示“一时的能力”,即“在过去某时有某种能力,并顺利地完成某事”,则要用was/ were able to, 而不能用could。

Though he was sick, he was able to swim across the river. 虽然他病了,但他还是游过了河。

(7)Most of the time, we make promises to other people. 大多数时间,我们向其他人作出承诺。

①“most of+限定词+名词”=“most+名词”,表示“大多数.......”。

Most students go to school by bike.= Most of the students go to school by bike. 大多数学生骑自行车去上学。

②promise作名词,意为“承诺,诺言”。

常见短语有:

keep a promise遵守诺言

make a promise作出承诺

Give me your promise that you’ll never be late again. 答应我你绝不再迟到了。

拓展

promise to do sth.答应做某事

He promised to help us.他答应要帮助我们。

promise sb. sth.答应某人某事

He promised me the book. 他答应给我这本书。

promise that从句,答应/许诺...

I promised that I would give it to Susan. 我答应过把它给苏珊了。
