3)promise + that 从句Tom promises that he can return on time.

promise n. 允诺，诺言

2.when 与while 的区别：

when 表示“ 当… 时候” ，既指时间点，又指一段时间，when 引导的时间状语从句中的动词可以是终止性的也可以是延续性的。When the teacher came in, the students were talking.

When she arrives, I’ll call you.

while 表示“ 当… 时候” ，仅指一段时间，从句中的动作必须是延续性的，一般强调主从句的动作同时发生，while 还可以作并列连词，意为“ 而、却” ，表示对比关系。

Lisa was singing while her mother was playing piano.

Tom is strong while his younger brother is week.

3. practice vt. 练习，后接名词，代词或v-ing 作宾语。

4 . everyday 与every day 区别

everyday adj. 每天的在句中作定语，位于名词前。This is our everyday homework.

every day 副词短语，在句中作状语，位于句首或句末。He reads books every day.

2. How are you going to do that? 你打算如何做？

3. I'm going to take guitar lessons. 我打算上吉他课。

4. I want to be a teacher. 我想成为一名教师。

五、语法：动词的一般将来时（be going to 的用法）

1 ）be going to + 动词原形——表示将来的打算、计划或安排。常与表示将来的tomorrow, next year 等时间状语或when 引导的时间状语从句连用。

各种句式变换都借助be 动词完成，be 随主语有am, is, are 的变换，

going to 后接动词原形。

肯定句：主语+ be going to + 动词原形+ 其他。He is going to take the bus there.

否定句：主语+ be not going to + 动词原形+ 其他I’m not going to see my friends this weekend.

一般疑问句：Be + 主语+ going to + 动词原形+ 其他

肯定回答：Yes, 主语+ be.

否定回答：No, 主语+ be not.

Are you g oing to see your friends this weekend? Yes ,I am. / No, I’m not.

特殊疑问句：疑问词+ be + 主语+ going to + 动词原形+ 其他？

What is he going to do this weekend? When are you going to see your friends?

2) 如果表示计划去某地，可直接用be going to + 地点

We are going to Beijing for a holiday.

3) 表示位置移动的动词，如go , come, leave 等常用进行时表示将来。

The bus is coming. My aunt is leaving for Beijing next week.

4) be going to 与will 的区别：

对未来事情的预测用“ will + 动词原形” 表达，will 没有人称和数的变化，变否定句要在will 后面加not, 也可用will 后面加not, 或者缩略式w on’t, 变一般疑问句将will 提至句首。

Will planes be large in the future? Yes, they will. / No, they won’t.

will 常表示说话人相信或希望要发生的事情，而be going to 指某事肯定发生，常表示事情很快就要发生。I believe Lucy will be a great doctor.

陈述将来的某个事实用will .

I will ten years old next year.

表示现在或将来要做的事情用will.

I’m tired I will go to bed.

表示意愿用will.

I’ll tell you the truth.

表示计划、打算要做的事情用be going to, 而不用will.
