GMAT语法有很多零散的知识点，这些知识点要求我们系统的掌握，从而了解GMAT语法的正确规则，今天我们就给大家说一下GMAT语法like的用法讲解。
一. Like 用法三原则
原则一：like比较的是名词和名词。要找准比较对象。
原则二：Just like 是wordy, like就可以了。Like**, **also 也是redundant。
原则三：要把like的句子改写成as(连词)引导的从句的话，要补上从句的谓语动词(或助动词)，并且该动词和主句的动词应该没有逻辑上的矛盾。
二. Like九条及例题
woodorstone总结得挺好。我自己也总结了9条，改了改发出来，一家之言，仅供参考。例子太长，没贴，可根据文中题号，到大全987和og里找到。
1. as作连词，like作介词时，才可表示”象...一样”
2. like 和 as 的优缺点
like优点是，直接接名词，简洁，比as灵活，象得没as那么象。但有时太灵活以至导致歧义(e.g.,og060.A)。相比之下as的优点是准确，缺点是过于死板，以致于有时导致逻辑上不通。(e.g.,og119.C)
3. like 常用于比较名词，作独立成分，大部分时候出现在句首。(e.g.,og091)但like+n.也可作表语 (looks like, reads like (e.g.,大全568))，或普通状语 (说普通是区分独立成分)(v.+like+n.,e.g., og119)。平时我们说“work like a dog”,即属此类。
4.当like+n.作状语时，象所有的介词短语作状语一样，要考虑它在句中的位置和用来修饰什么，不可导致歧义。
5. 当like+n.作状语时，感觉GMAT接受v.+like+n.，很少用v.+n.+like+n.,除非是固定用法(如：treat...like... (大全310))。例如下面的句子，GMAT会认为confusing：
Tom drives his car like a tank. (drive like a tank, or car like a tank?)
6. like, as, 和 as if。当用as和like都感觉不舒服时，用as if+虚拟语气，尤其用于和假设的事物或事实比较。
如上面的句子用as不行，因为Tom drives his car as he drives a tank。显然不妥，因为Tom未必开坦克。但可以这么说：Tom drives his car as if it were a tank。(大全310)
7. "n1, like n2" 和 "n1, such as n2"。表“比如...”，只能用such as;而表“象...”时，用like。或说，当n2是n1的子集时，用such as;当n1和n2为平行可比物时，用like。记住such as一般对，也小心“大全229”那样的陷阱。
8. "like this/these" 和 "sth. of this kind"，改成"such+n." (e.g.，大全792)
9. like和unlike。unlike只作独立成分和表语，没见过unlike作普通状语。He works unlike a dog (别扭)。注意 "is not unlike" 表强调，不要改成"is like"。 (e.g., og051)

OG对like的讲解
1.Like many self-taught artists, Perle Hessing did not begin to paint until she was well into middle age.
(A) Like
(B) As have
(C) Just as with
(D) Just like(A)
(E) As did
Choice A, the best answer, is concise and grammatically correct, using the comparative preposition like to express the comparison between many self-taught artists and Perle Hessing. Choices B and E, which replace A’s prepositional phrase with clauses introduced by as, use auxiliary verbs that cannot properly be completed by any part of the verb phrase in the main clause: neither have... did not begin nor did... did not begin is logically or grammatically sound. In C and D, Just as with and Just like are both unnecessary wordy.
以上就是关于GMAT语法like的用法讲解的内容介绍，希望考生通过以上内容，不断夯实自己的知识点，熟练做题技巧，提升解题能力以及分析能力，争取都能取得理想成绩。
