专题：比较结构
总原则：比较对象要对等

在比较结构中，助动词的补出问题：语义来看补不补
1.        只有当比较对象是主语时才涉及助动词的补出问题，比较对象是宾语不补
Tom often eats more apples than Jerry dose 不补产生歧义
Tom often eats more apples than pears
2.        在比较的as/than后主语可直接跟助动词=倒装
Y plays tennis better than dose Z
3.        有可能引起误会要补助动词  
Y plays tennis better than Z 产生歧义tennis better than Z
Y plays tennis better than Z dose
4.        误会：前句有宾语或类宾语，不同时间比较 例题:p11/14
They will expect to live better than their parents did
做题步骤：先判断是不是主语的比较，不是不补；再看不补助动词有没有误会，误会就补
例题:p245/19 74/1

s

专题：状语从句
状语从句中 although, if, when后面发生省略(S +be)的条件：
        从句是(S +be)结构
        从句主语S’ =主句主语S
例题:p20/6

s

比较语法点
More …than…/as…as…/more than比较
More …than…/as…as…
        倍数后面两者通用
        非倍数后面只能用more…than…
        不可以混搭
more than   例题: p15/8
        more than= over 用在数字前
        more than + adj = very
        more than + n =not only
        more than + v =greatly
Double /twice比较
Two times——100%错 语义重复
Twice = adv  
Double 可以乱用
例题: p259/72  例题: OGp681/125

s

Like /as比较 必考
GMAT中：Like =像  prep+ n/doing （举例用such as） A与主句主语B对应
        B V C ,LIKE A
        B ,LIKE A, V C
        LIKE A, B V C
As  连词conj + 句子SVO
Likely   adv/adj   eg. Tom is likely to kill you
例题:OGp659/9、p672/82、p661/20 例题:p263/91、p245/16、p257/64
And/also/together with/along with比较
And 连词，可以使得N个并列对象从语法到语义都成为完整的意思
Also 副词，可有可无，作状语，不影响句子结构
Together with = Along with 介词短语，语义上并列前面的中心词，语法上没有任何并列作用
Eg. A of B, together with C —— A是中心词  例题:OGp681/130
“能力”比较
能力一定是主动的；can be done可能正确，因为can 可以不表能力
1.        Can
2.        Be able + to do
3.        The ability + to do
4.        Be capable + of doing
5.        The capability + of doing/to do
例题:OGp663/34 669/62
As well as/not only…but als比较
As well as并列V时，用作介词; 介词省略的平行——介词尽量保留
Eg. She sings as well as playing piano.  例题:p278/149
A as well as B = not only B, but also A
强调重心不一一样as well as强调重心在前面——A
So…that /so…as to比较
S + be + so…that /so…as to do如此以至于  例题:OGp660/174例题:p263/88 103
这类题出现ENOUGH选项——100%错
Such的表达一般不选
S（sb）+ be + so…as to do  to do的逻辑主语必=S（sb）
允许、禁止比较
Allow, permit/forbid + sth/sb to do
Prohibit + sb from doing

s

固定搭配/常用语法点
Being对的情况
        被动的动名词作主语宾语或介宾
I hope to get out without being seen 被动动名词（主动doing）
        Be + being done 进行时的被动语态
Tom is kicking jerry = jerry is being kicked
例题:p247/24
“，”特殊用法
        adj, adj + N条件：2个adj修饰同一个N，2个adj排序
        adv, adj
例题:OGp664/40 例题:p250/37
所有格 ” ’s”
A’s B = B of A’s  A的B中的一个
B of A         A的B（这时的B不能有很多）eg. The size of C——C只有一个size
例题:p241/2
As
Depict, view, regard, use, cite, think of, conceive of + A + as + B
Function, serve, act + as 作为
例题:p274/134
While
当SVO while SVO时，常见省略SVO while doing
The more
The more 结构中 be + verb可省略  例题:p241/7,10
Try
Try to do/try doing尝试做
Not….but….
1.        词组：不一定在助动词后，X、Y要平行  eg. M is killed not by Tom/ not X but Y
2.        不做词组：各自独立 s is not a book, but composes
例题:p246/22
Distinguish
Distinguish A from B  例题:p224/15
Distinguish between A and B

s

一定错！
Do it 改成do so
Maybe改may be perhaps probably   例题:OGp658/4
There be 罗嗦
There be/such + 别的选项的同根N——100%错   例题:p241/20
逻辑主语：（Being）adj + prep +n，SVO选项中有being——100%错
Consider + as/to be——100%错
Being——95%错
Two times——100%错
分词的完成式作后定N+ having done/N+ having been done——100%错
