二、 Important Sentences structures
1. Birds start singing and making their nests.
鸟儿开始歌唱和筑巢。
(1) start doing something意为“开始做某事；着手做某事”。
She started playing / to play the piano when she was six. 她六岁开始学弹钢琴。
(2) make one's nest是“（鸟儿）筑巢”的意思。
Birds usually make their nests in the trees.鸟儿通常在树上筑巢。
2. The holodays are ending. 假期就要结束。
上述句子用现在进行时表将来。现在进行时除了描述正在发生的动作之外，还常常用来描述即将发生的事情，与be going to do something的含义接近。
试比较：
-Where are Sue and Caroline 苏和卡洛琳在哪儿？
-They're playing tennis in the park. 她们正在公园里打网球。（表示正在发生的事情）
Alice is going to see the dentist on Friday. 艾丽斯星期五要去看牙医。（表示对将来的安排或计划）
我们也可使用一般现在时表示将来的含义，不过仅限于一些时间表、节目单、列车的出发或到达时间等，用于通常都有固定时间安排的情况。
The train arrives at 7:30 p.m. 列车将于晚上7点半到达。
What time does the film finish 电影几点结束？
3. -What does spring make you think of
春天使你们想起了什么？
-Spring makes me think of rain. 春天使我想起了雨。
make somebody do something
意为“使某人做某事”，make后接动词不定式时，不能带to。如：
My boss makes me work 12 hours a day. 我的老板让我每天工作12个小时。
4. It’s interesting to see them flying around the flowers.
能看到它们（指蝴蝶）飞舞在花丛中真是很有意思。
本例中的it是句子的形式主语，“It is+形容词十to do something”的结构用来表示“做某事怎么样”。
It is dangerous to play in the street. 在街上玩耍很危险。
【友情提示】 如果要说明动词不定式表示的动作是谁做的，动词不定式之前的形容词是表示事物性质的（如：easy，difficult，important等）。可以在动词不定式前加一个for引导的短语。
It is not hard for one to get up early. 一个人早起并不难。
如果be动词后面接指有关人的赞美或批评的形容词（如：clever，kind，foolish等）时，动词不定式前常加一个of引导的短语来说明动词不定式所指的对象。
It is very kind of you to come and meet us. 你来接我们真好。
指点迷津：see sb. do sth. 与see sb. doing sth.
(1)see somebody do something意为“看见某人做了某事”，表示动作的整个过程。
(2)see somebody doing something意为“看见某人正在做某事”，表示动作正在进行。
5. All summer, the grasshopper sat in the sun and sang happily all the time. 整个夏天，蚱蜢一直晒着太阳，开心地唱着歌。
all summer意为“整个夏天”。all后加表示一段时间的名词常常作为句子的时间状语。
I did my homework all evening. 我一晚上都在做家庭作业。
【友情提示】 “all+名词”构成的时间状语前不能加任何介词。
in the sun意为“在太阳底下；在阳光下”，不可以说under the sun。
The leaves become dry in the sun.叶子在骄阳下都蔫了。
6. He collected food and took it into his house. 他到处找食物，并把食物搬进自己的房子。
take something into some place意为‘‘把……搬入……中”。
Would you please take the suitcase into my room for me 你可以帮忙把行李箱搬到我房间去吗？
【拓展】 take还有如下含义：
(1)拿；取：I want to take some books to the classroom. 我想拿些书到教室去。
(2)吃；喝；服用；添加：Take this medicine three times a day. 这种药每天吃三次。
(3)乘车（船）等：They usually take a bus to work. 他们通常乘公交车上班。
(4)花费（时间、金钱）等（常常和it连用，it在句子中作形式主语，真正的主语是后面的不定式）：
How long will it take you to do your homework every day 你每天做作业要花费多长时间？
(5)“做……事情”，常和名词连用，表示与该名词意义相关的动作。
如：take a walk（散步），take a rest(休息一下)，take a look(看一看)等。
7. There will be plenty of food in the forest in winter.
冬天，森林里会有很多食物的。
这是there be句型的一般将来时用法。There be句型常见于一般现在时、一般过去时、一般将来时和现在完成时中。
There is a train every hour. 每小时都有一班火车。(一般现在时there is/are)
There was a good film on TV last night. 昨晚电视里放了一部很不错的电影。(一般过去时there was/were)
This road is very dangerous. There have been many accidents.
这是一条很危险的道路，已经发生了很多事故。(现在完成时there have/has been)
I’ m going away tomorrow. I'll do my packing today because there won't be time tomorrow.
我明天要出差，今天我要打好包，因为明天没有时间。(一般将来时there will be)
8. He felt cold, hungry and disappointed.
他觉得冷得刺骨，又饿又失望。
felt是动词feel的过去式。feel是一个系动词，意为“感觉到”，后接形容词cold，修饰句子的主语he。类似的感官系动词有：look（看上去），sound(听上去)，smell(闻起来)，taste(尝起来)等。它们都可接形容词作表语，修饰句子的主语。
-You look tired. 你看上去很累。-Yes, I feel tired. 是的，我觉得很累。
George told me about his new job. It sounds very interesting. 乔治给我讲了他的新工作，听起来很有趣。
9. What's the matter, my friend 我的朋友，你怎么了啊？
What’s the matter 意为“怎么了？；出什么事情了？”，相当于What’s wrong ，What's the trouble 或What's the problem 等。
如果询问某人出了什么事情或某物出了什么问题，可以说：What's the matter with…？
10. When spring comes, I'll work hard like you.
等到春天来了，我也会像你一样勤奋地工作。
这是一句由when引导的时间状语从句。当它用来表示将来的含义时，主句部分需使用一般将来时，而从句部分应使用一般现在时表将来，简称为“主将从现”。
I will send you some postcards when I am in Australia next month. 下个月我去澳大利亚的时候会给你寄些明信片。
like在这里作介词，意为“像……”。
The boy looks quite like his father. 这个男孩跟他父亲长得很像。

三、语法讲解
1. It is+形容词+to…
It is+adj. +to do sth. 做某事…
例如：It’ s easy to learn swimming. 学游泳很简单。
It is+adj. +doing sth.
做某事很……（对话结束时使用）
例如：It was nice talking to you. 和你谈话很愉快。
It十is+adj. +for+sb. +to do sth. 对某人来说做某事真是太……了。
本句型中的形容词通常是表示客观情况的。
如：easy, hard, difficult, important, necessary, impossible, interesting等。
例如：

对他来说，按时完成这项工作真是太难了。
It is necessary for us to study English well.
对我们来说学好英语是必要的。
2. 使役动词make
“make+宾语+宾语补足语”的这一结构用得很多，其中宾语补足语部分可以用形容词、介词短语、名词、不定式、分词等充当。
“make+宾语+形容词作宾语补足语”。
例如：
We are working hard to make our country more beautiful. 我们正努力工作，使我们的国家更美丽。
“make+宾语+介词短语作宾语补足语”。
例如：
Mother made her coat into my skirt.
母亲把她的外套改成裙子给我穿。
“make+宾语+名词作宾语补足语”。
例如：
We made him our monitor. 我们都选他当班长。
“make十宾语十省略to的不定式作宾语补足语”，若将其改为被动语态，to须加上。
例如：
The boy makes faces just to make others laugh.
这个男孩做鬼脸的目的是让其他人笑。
【随堂小练】
【例1】 The workers were made___________12 hours a day at that time.
A. working B. work C. to work D. worked
【答案】 C
【名师点拨】 在被动语态中不定式作宾语补足语时，to不能省略。
【例2】 Every one of us knows some kinds of clothes______wood.
A. make of B.make from C.are made of D. are made from
【答案】D
【名师点拨】 语境表示“衣服是用木头做的”，看不出所使用的原材料，故用be made from。
