◆unit 1 Will people have robots?
知识点：
1． 形容词，副词的比较等级考查热点透视：
a) 表示A与B在程度上相同时， “as+形容词或副词的原级+as”结构。表示A不如B时，可用“not as/so+形容词或副词的原级+as”结构。
b) 表示A比B在程度上“更…..”时，可用“形容词或副词的比较级+than”结构
c) 表示三者或三者以上的比较，其中一个在程度上“最…..”时，常用“the+形容词或副词的最高级”结构，后面可带“of/in的短语”来说明比较的范围。（注意：副词的最高级在句中常省略“the”.）
d) 在形容词或副词的比较级前，可以用“a little, even, far, much,still”的等词语来修饰，以加强语气。
e) 表示“越来越….”时，常用“形容词或副词的比较级+and+形容词或副词的比较级”结构，但要注意，对于多音节和部分双音节形容词，副词而言，若要表达此意时，要用“more and more+形容词或副词的原级“结构。
f) 在表示“其中最….之一“的含义时，常使用 “one of+the+形容词最高级形式+名词复数”结构，其中的定冠词the不可以省略。
g) 如果强调“两者中比较…的（一个）”的意思时，可使用“the+形容词比较级+其它”结构。
h) 表示“越….越….”, 可使用“the+形容词或副词的比较级，the+形容词或副词的比较级”结构。
2 .一般将来时
a) 一般将来时的构成：由助动词shall或will加动词原形构成，shall用于第一人称。在口语中，will在名词或代词后常简略为’ll， will not常简略为won’t。这个时态的肯定，否定和疑问结构可表示如下：
肯定句 否定句 疑问句
I (We)shall(will) go.
You(He, She, They) will go. I(We)shall(will) not go.
You(He, She, They)will not go. Shall I(we) go?
Will you (he, she, they) go?
用”be going to +动词原形”也可表示将来时，表示将要发生的事，打算或决定要做的事。
b)一般将来时的用法：1）表示将要发生的动作或情况；2） 不以人的意志为转移，肯定要发生的事情。The day after tomorrow will be National Day.后天是国庆日。
3. in/after:in是指以现在时间为起点的“在一段时间以后”。也可以表示“在将来多少时间之内”，句子中的谓语动词要用一般将来时态；after常指以过去时间为起点的“一段时间之后”，所以它与过去时态连用。当after指某个特定的未来时刻或日期之后，或指以将来某一时间为起点的若干时间之后时，它可以与将来时态连用。
4.more, less, fewer的用法区别：more为many, much的比较级，意为“更多”，可修饰可数与不可数名词。Less是little的比较级，意为“更好，较少”，修饰不可数名词。Fewer是few的比较级，意为“更少”，修饰可数名词复数。
【注意】few, little表示否定“几乎没有”。a few, a little表示肯定“一点，几个”。
5.would like sth意思为“想要某物“； would like to do意思为”想要做某事“。回答would like句型的一般疑问句时，其肯定回答为 “Yes, please.”;否定回答“No, thanks”或 “I’d like /love to, but….”
6. Such作形容词，意思是“如此的”“这样的”，修饰各种名词。
? Such这样的。如It is such bad weather.天气如此恶劣。
? Such常和as搭配，表示一种类别。如We enjoy such a voice as hers.我们喜欢象她那样的嗓子。
? Such常和表示结果的that从句搭配，表示“如此….以至于…”如
It was such a hot day that we all had to stay at home.
