Unit22 A world of fun
· 重点句型解析 ·
1．What do you think you can see in a theme park?
你认为在主题乐园你能看到什么呢?
英语的疑问句通常有四种，即一般疑问句、特殊疑问句、反意疑问句和选择疑问句．但还有一种特殊形式，如What do you think I should do?这一句型，就被称为混合疑问句．这种疑问句由两个疑问句组成，句型为：疑问词+do you think+其他(正常语序)．常用于这种结构的动词有think，guess(猜)，suggest(建议)，suppose(认为)，hope，say，believe等．
e．g．What do you think has happened to him?你认为他出了什么事?
How many people did you say were present at the meeting?你说有多少人出席了会议?
此类句型常用来征询对方对某一疑问点的判断、认识、看法、猜测等，或者请求对方重复一遍．
e．g．How old did you say you were?你刚才说你多大了?(多少岁)
What did you say was the matter with him?你说他怎么啦?
注意：不能说What did you say the matter was with him?在口语中，可以把do you think一类的插入语放在句末带有补叙的性质．
e．g．When the meeting will be held，do you think?会议什么时候举行你说呢?
这种表示看法的插入语：I think，I guess等也常用在陈述句中．
New York，I think，is too noisy．纽约，我认为太吵了．
I think New York is too noisy．我认为纽约太吵了．
插入语在句首，则变成了主句，后面接宾语从句．
e．g．Who did it，do you think? Who do you think did it?你认为是谁干的?
2．At the Lowland，they can explore the past at the discovery of the Ancient World and examine giant footprints at the dinosaur exhibition．在低地，人们能够在“远古世界的发现”里探索过去，在恐龙展览厅里研究恐龙巨大的脚印．
(1)explore the past意思是“探索过去”．past在句中用作名词，意思是“过去，昔日”，如in the past在过去．用作形容词，意思是“过去的”，如the past year去年．用作介词，意思是“过”，如ten past eleven 11点过10分．pass用作动词，意思是“走过，经过，度过，通过”等，过去式是passed，过去分词是passed或past．
e．g．Please let me pass．请让我走过去． A week passed quickly．一个星期很快过去了．
(2)ancient用作形容词，意思是“古代的，古老的”(常用来指古老的文明或其产品)．
e．g．ancient civilizations古代的文明
(3)giant用作形容词，意思是“巨大的”．
e．g．What a giant panda!多大的熊猫!
3.Many people come to theme parks looking for thrills and entertainment.
很多人来到主题公园寻找快乐和刺激。
looking for thrills and entertainment. 在句中作状语。这种-ing form 作状语时，通常都表示主语正在进行的另一动作，来对谓语表示的主要动作加以修饰或作为陪衬。如：
They stood there for an hour watching the game.他们在那儿站了一个钟头看比赛。
Please fill in this form, giving your name, address, etc.
请把这份表填一下，写下你的姓名、住址等。
注意：（1）-ing form 表示的必须是主语的一个动作；
（2）-ing form表示的是较次要的动作，对谓语表示的动作或状态加以说明；
（3）-ing form表示的动作和谓语表示的动作（或状态）是同时发生的，如果表示的动作在谓语动作之前发生，就需要用完成时。例如：
They sat facing each other.他们面对面地坐着。
Working this way, they greatly reduced the cost.用这种办法他们大大降低了成本。
Having never handled a machine, she met with a lot of difficulties at first.
由于她从来没开过机器，一开头她碰到很多困难。
如果谓语动作和-ing form表示的动作是完全同时发生的。分词用when或while加-ing form：
Be careful when crossing the street.过街时要小心。
She got to know them while attending a conference in Beijing.她是在北京开会时认识他的。
Don't mention this while talking to him.和他谈话时不要提这件事。
4．Theme parks also try to make sure that visitors have knowing more about their theme.

make sure that / wh- 确定，查明，弄清楚
