例如:

【拓展】

例如:
We can’t go out as a result of the heavy rain. 因为下大雨,我们不能出去。
2. waste
(1) waste 作不可数名词,意为“浪费,废物,垃圾”。
例如: I hate waste. 我讨厌浪费。
(2) waste 作形容词,意为“无用的,浪费的,荒废的”。
例如: We shouldn’t throw waste paper about. 我们不应该乱扔废纸。

(2) pass 作名词,意为“关口,通过”。

例如: I often borrow books from the library. 我经常从图书馆里借书。
(2) “lend…to”意为“把……借(出)……”。
例如:I lend my book to Lily. 我把我的书借给莉莉了。
5. depend
depend意思为“依靠、依赖、取决于”等,只用作不及物动词,通常与介词 on, upon 连用,主要用法有:
(1) depend on/upon+某人或某物
例如:
Whether we’ll go camping depends on the weather.我们是否去野营要看天气。
有时可在某人或某物后用介词for。
例如:
Children depend on their parents for food and clothing.儿童的衣食靠父母。
(2) depend on [upon]+从句
例如:
Our success depends on whether everyone works hard or not.我们的成功取决于每个人是否努力。
The amount you pay depends on where you live.你付多少钱要看你住什么地方。
(3) 口语中说 It (all) depends. /That depends.意为“那要看情况”。
例如:
——Are you going too 你也去吗
——That depends. 那要看情况。
(4) depend on意为“视……而定;取决于;依靠”,其后可跟名词、代词或从句作宾语,on也可以换为upon。
例如:
——When shall we start 我们什么时候动身?
——It depends on(upon) the weather. 依天气情况而定。
6. while
(1) while作连词时,可以意为“当……时候, 和……同时”。

7. provide
provide为及物动词,意为“提供”,常和with搭配。provide sb. with sth.表示“为某人提供某物”,其同意表达为 provide sth. for sb.。
例如:
The Sun provides us with light and heat.太阳给我们提供光和热。
Sheep provide us with wool. /Sheep provide wool for us.羊供给我们羊毛。
8. since

例如:

Since you are so sure of it he’ll believe you.既然你对此这么有把握, 他会相信你的。
四、重点句型解析
1. Could you please clean your room
“Could + 主语 + please + 动词原形 + 其他?”这一句型相当于“Could + 主语 + 动词原形 + 其他,please?”意为“请……,好吗?”。这两种句型均表示礼貌的请求,语气委婉,客气。其中could在此句中不表示过去,而表示说话人的语气委婉。因此回答时,不能用could回答。
例如:
Could you please help me with my English = Could you help me with my English, please 请你帮我学英语好吗?
——Could I have a look at it, please 请让我看一看它好吗?
——Certainly!当然可以。
2. They should …in order to get good grades and get into a good university.
(1) 本句中的in order to是一个固定搭配的短语,意思是“为了”,后接动词原形构成不定式结构在句子中作目的状语,否定形式是在to前面加not。in order to可以和so as to 互换,但后者不能放在句首。
例如:
In order not to be late, you should go now.为了不迟到,你现在应该走。
(2) in order to+动词原形和so as to+动词原形可以转换成in order that+从句和so that+从句。
例如:
He did anything in order to make money.= He did anything in order that he could make money.为了赚钱,他什么都做。
Please go in quietly so as not to wake the baby.=Please go in quietly so that we won’t wake the baby.请不声不响地进去以免弄醒孩子。
3. For one week, she did not do any housework and neither did I.
“neither +be动词/助动词/情态动词 + 主语”表示“……也不”,指后者与前者具有相同的情况,但是表示的是否定意义的相同。相当于一个主谓倒装的否定句。neither 此处意为“也不”,是副词。
例如:
Mary doesn’t like singing. Neither do I.玛丽不喜欢唱歌,我也不喜欢。(我和Mary 有相同的情况,前句是否定句,下文用neither开头,主谓倒装)
如果上文是肯定句,下文表示与上文有相同情况时,用“so+ be动词/助动词/情态动词 + 主语”。
例如:
Mary likes singing. So do I.玛丽喜欢唱歌。我也喜欢。(我和Mary有相同情况,前句是肯定句,下文用so开头,主谓倒装)
【拓展】
当表示对上文所讲内容的赞同时,可以用“so + 主语 + be动词/助动词/情态动词”或者“neither + 主语 + be动词/助动词/情态动词”来表示。前者用于肯定句,后者用于否定句。
例如:
Mary plays the piano well. So she does.玛丽钢琴弹得很好。她确实弹得好。(表示对上文所讲内容的赞同,前句是肯定句,下文用so开头,主谓不倒装)
Mary doesn’t play the piano well. Neither she does.玛丽钢琴弹的不好。她确实弹得不好。(表示对上文内容的赞同,前句是否定句,下文用neither开头,主谓不倒装)
4. And she won’t be happy if she sees this mess.
(1) 本句中if后面的部分是这个句子中的条件状语从句。在以when,after,as soon as等引导的时间状语从句以及以if,unless等引导的条件状语从句中,如果主句是一般将来时,从句则用一般现在时表将来。
例如:
I’ll tell her the good news when she comes back.当她回来的时候,我将把这个好消息告诉她。
If it doesn’t rain, he will come here on time.如果不下雨,他会按时来这儿的。
* 常见的“主将从现”有以下三种情况:
1)条件状语从句的主句是一般将来时,那么从句常常用一般现在时。
例如: When I grow up, I’ll be a nurse and look after patients. 我长大后要当一名护士,照顾病人。
2)如果主句是祈使句,那么从句通常要用一般现在时。
例如:Don’t laugh at me when I make a mistake. 我犯错误的时候不要笑话我。
3)如果主句是含有情态动词的一般现在时,根据需要从句多用一般现在时。
例如:You should be quiet when you are in the reading room. 在阅览室时应保持安静。
5. I do not understand why some parents make their kids help with housework and chores at home.
本句中的make作使役动词,意为“使……;让……”讲时,常构成make sb. do sth. 意为“使/让某人做某事”,类似的动词还有let,have等。
例如:
The boss made them work for long time. 老板让他们长时间工作。
They made us forget past. 他们使我们忘记了过去。
Their boss often let them work long hours every day. 他们老板经常让他们每天工作很长时间
【拓展】
make作使役动词,还可以构成:make + 宾语(sb./sth.) + 形容词/名词(作宾补),即make sb. / sth. + adj./n.。
例如:
What he said makes us happy. 他所说的话使我们很高兴。
We made John our monitor. 我们选约翰当班长。
五、语法
宾语从句
1. 疑问词引导的宾语从句
当宾语从句是特殊疑问句时,疑问词就是引导词,这时疑问词不可省略,而且宾语从句要用陈述语序,即:疑问词+主语+谓语+其他?
Where will we have a meeting 我们将在哪儿开会?→ Could you please tell me where we will have a meeting 你能告诉我我们将在哪儿开会吗?
What should I do next 下一步我该做什么?→ I wonder what I should do next. 我想知道下一步我该做什么。
2. 含有宾语从句的复合句与简单句的转换
含有宾语从句的复合句在一定条件下可以转换为简单句。若主句的主语或宾语与从句的主语一致,则由疑问词引导的宾语从句可以变成“疑问词+动词不定式”的复合结构。我不知道下一步应该怎样做。
I don’t know how I should do it next. → I don’t know how to do it next.
3. 当主句谓语动词是see, hear, watch等时,其后的that从句常简化为“宾语+动词原形/动词-ing形式”。
I saw some boys were playing basketball on the playground just now.→ I saw some boys playing basketball on the playground just now.刚才我看到一些男孩正在操场上打篮球。
4. 当主句的谓语动词是hope, agree, wish等,主句的主语或宾语与从句的主语一致时,其后以that引导的宾语从句可简化为动词不定式结构。
He agreed that he could help me with my English.→ He agreed to help me with my English.他同意帮我学习英语。

Dear Mom and Dad,
Thanks for your e-mail. I'm glad you are getting on well with your work. Now let me tell you something about us. We are doing quite well at home. On the first day, we got up early. We both did some chores. Tina made the beds andswept the floor. I made breakfast and did the dishes. Though I broke a dish, we were very happy doing the chores. After breakfast, we did our homework together. After lunch, we watched TV and played games. We played very happily.Don't worry about us. I can look after myself and Tina well.
I think we will do better next time. Have a good time!
Yours,
Mary
