八年级下册英语语法
  八年级下册英语语法:一般将来时

1. 表示将要发生的动作或存在的状态。本时态标志词:

① 含 tomorrow; next 短语;② in + 段时间 ;③ how soon;

④ by + 将来时间;⑤ by the time sb. do …;⑥ 祈使句句型中:or/

and sb. will do;

⑦ 在时间/条件状语从句中,如果从句用一般现在时,主句用将来时;⑧ another day 比较 be going to 与 will:

be going to 表示近期、眼下就要发生的事情,will 表示的将来时间则较远一些。 如:He is going to write a letter tonight. He will

write a book one day.

2. be going to 表示根据主观判断将来肯定发生的事情,will

表示客观上将来势必发生的事情。

He is seriously ill. He is going to die. He

will be twenty years old.

3. be going to 含有“计划,准备”的意思,而 will 则没有这个意思,如:

She is going to lend us her book. He will be

here in half an hour.

4. 在有条件从句的主句中,一般不用 be going to, 而多用 will。如:

If any beasts comes at you, I'll stay with you and help you.

掌握了它们的这些不同,你就能很好的区分 be going to 与 will 了。

一般将来时常见的标志词

① 含 tomorrow; next 短语; ② in + 段时间 ;

③ how soon; ④ by + 将来时间;

5. 祈使句句型中:or/ and sb. will do

例:Be quick, or you will be late = If you don't be quick, you will be late

6. 在时间/条件状语从句中,如果从句用一般现在时,主句用将来时

  八年级下册英语语法:过去进行时

句型 S + was/ were + V-ing …

例1:She was doing her homework at 8:30 yesterday

evening 昨天傍晚八点半她正在做家庭作业。

例2:We were having supper at that time 那个时候我们正在吃晚饭

解说:如例1所示,在单句中使用过去进行时来表达时必须把该动作正在进行中的时间表明清楚,否则就不合逻辑了。例如:I

was taking a bath yesterday. (错)

(昨天我正在洗澡——昨天24小时都正在洗澡吗?)

所以本句应该如例1来表达,或者用一般过去时表达如下:

I took a bath yesterday. 昨天我洗了澡

如果由上下文的文意,或者对谈中的话意可以了解“动作正在进行中的时间”,单句里就使用过去进行时来表达是很普通的,例如:

A:I called you up yesterday evening.

B:Did you? At what time?

A:At around ten o'clock. 大约在十点钟。

B:Oh, I was taking a bath then. 哦,当时我正在洗澡。

过去进行时在表达上常用的句式是如例2所示和另一个一般过去时的动作相搭配。请观察下面的图解说明: 过去有二动作A和B(如图示),在B动作发生时稍早发生的A动作正好在进行中,所以这种表达法通常都是复句(主句

+ 副词从句)。例如:

When I got up this morning, Mother was

preparing breakfast in the kitchen.

(今天早上我起床时妈妈正在厨房里准备早餐。“Mother ….”是主句,“when …,”是副词从句。)

常用于修饰过去进行时的时间副词:过去的某一定点时刻(at + 过去的时刻),then (=

at that time) (那时,当时),all + 时间,“When …/ While …/

As …”等副词从句,etc

  八年级下册英语语法:疑问句的间接引语

直接引语如果是疑问句,变成间接引语后,叫做间接疑问句。间接疑问句为陈述语序,句末用句号,动词时态等的变化与间接陈述句相同。引述动词常用

ask, wonder, want to know 等间接疑问句一般有三种:

(1) 一般疑问句由直接引语变为间接引语时, 由 whether 或 if 引导。 如: “Has he ever worked in Shanghai?”Jim

asked.“他在上海工作过吗?”吉姆问。

→Jim asked whether/ if he had ever worked in

Shanghai. 吉姆问他是否在上海工作过。

“Can you tell me the way to the hospital?”The

old man asked.

那个老人问:"你能告诉我去医院的路吗?

→The old man asked whether I could tell him the

way to the hospital.

那老人问我是否能告诉他去医院路。

(2) 特殊疑问句由直接引语变为间接引语时,仍由原来的疑问词引导。 如: “Which room do you live in?”He asked.

“你住哪个房间?”他问我。

→He asked me which room I lived in. 他问我住哪个房间。

“What do you think of the film?”She asked.

她问:“你怎么看这部电影?”

→She asked her friend what she thought of the

film. 她问她朋友怎么看这部电影。

(3) 选择疑问句由直接引语变为间接引语时,由 whether/ if … or 引导。 如: “Is it your bike or Tom's?”Mum asked.

妈妈问:“这是你的自行车还是汤姆的?”

→Mum asked whether/if it was my bike or Tom's.

妈妈问这是我的自行车还是汤姆的。

“Does your sister like blue dresses or green

ones?”Kate asked.

“你妹妹喜欢兰色的裙子还是绿色的?”凯特问。

→Kate asked whether/if my sister liked blue

dresses or green ones.

凯特问我妹妹喜欢兰色裙子还是绿色的。

3. 祈使句的间接引语当祈使句变为间接引语时,间接祈使句的引述动词常用 tell, ask, order, beg, request, order 等,而把直接祈使句变成带to的不定式短语。如: Jack said,“Please come to my house tomorrow,

Mary.”杰克说:“玛丽,明天请到我家来。”

→Jack asked Mary to go to his house the next day.

杰克请玛丽第二天到他家去。

The teacher said to the students,“Stop

talking.”老师对学生们说:“不要讲话了。”

→The teacher told the students to stop talking.

老师让学生们不要说话了。

“Don't touch anything.”He said. “不要碰任何东西。”他说。

→He told us not to touch anything. 他对我们说不要碰任何东西。

Unit 5 If you go to the party, you'll have a

great time!
