　　12. unlike 这个结构的平衡.

　　考点：1. 平行 2.unlike的比较结构

　　平行，简单过一遍，大家有不会的地方请对应的翻笔记哦

　　1. 做题步骤：1.找平行marker 2. 看相互平行的成分是否在描述同一件事?(语意平行)3. 看是否结构平行

　　2. 结构平行

　　1. 名词:

　　实意名词//实意名词(i.e. holiday, time)

　　动作名词//动作名词

　　动作名词//复杂动名词(a, the, an + ving or ving+prep介词)

　　复杂动名词//复杂动名词

　　简单动名词//简单动名词

　　1. 动词

　　动词//动词

　　不定式//不定式(i.e. to run and to play)

　　3. 分词//分词-现在分词可以和过去分词平行

　　Fatigued AND dreaming

　　1. 介词短语//介词短语

　　2. 句子//句子(clause//clause)

　　**注意：平行不要求主动-被动一致，即可以一个是主动语态一个是被动语态

　　**注意：现在时和过去时可以平行

　　i.e. She eats apples all the time AND drank some apple juice yesterday

　　**也有不完美平行的情况存在

　　i.e. They argue just as frequently and about the same topics as the couple living next door to them.

　　但是由于frequently和about the same topic都是描述“argue”的修饰语，所以可以接受该平行。

　　2.UNLIKE/ LIKE*五星级

　　a. like、unlike只能加名词，动名词，代词，短语

　　不能加句子和介词短语!什么?想加句子?那就用AS吧。

　　b. like只能作比较讲，不能用来举例，作比如讲用such as

　　like比较的必须是同类，特别注意所有格与名词的比较形式

　　c. like、unlike不加逗号容易产生歧义：

　　Ambiguous: I want to coach divers LIKE Greg Louganis.

　　Unambiguous:

　　加逗号比较主语：

　　I want to coach divers, LIKE Greg.

　　=Like Greg, I want to coach divers.

　　Shoppers in sporting goods stores, unlike in department stores, do very little impulse shopping, not buying a pair of skis and a boomerang when they come in for a basketball, but they leave with a basketball only

　　A. in department stores, do very little impulse shopping, not buying a pair of skis and a boomerang when they come in for a basketball, but they leave with a basketball only

　　B. in department stores, shop impulsively very little; someone who comes in for a basketball will leave with a basketball only and not also buy a pair of skis and a boomerang as well

　　C. those in department stores, do very little impulse shopping, do not buy a pair of skis and a boomerang when they come in for a basketball, but leave with only a basketball

　　D. those in department stores, do very little impulse shopping; someone who comes in for a basketball will leave with a basketball only and not buy a pair of skis and a boomerang as well (D)

　　E. department stores, shop impulsively very little; someone will not buy a pair of skis and a boomerang when they come in for a basketball but will leave with only a basketball

　　选项分析：

　　A. Unlike后面不可以加介词短语，即便省略也不能省去those;not…but…不平行，应改为but leaving with a basketball only，但这样改了也有but leaving修饰they come in for a basketball的歧义，还是不好

　　B. Unlike后面不可以加介词短语，即便省略也不能省去those;shop impulsively very little有另一个含义：冲动地买一些小东西(little可以作为adj.，不一定是adv.)，所以还是do very little impulse shopping更明确;also和as well重复;leave with only a basketball强调的是带走的是一个篮球，而不是两个或者更多，而leave with a basketball only强调的是带走的只是篮球

　　C. do very little impules shopping和do not buy a pair of skis一个是概括，一个是细化，功能不同无法平行，而且but不能连接三个并列成分，只能连接两个，所以即便不考虑逻辑上的层次，do not buy之前也要加上and

　　D. correct;两个不同层次却有联系的句子用semicolon连接是最合适的。And…as well在此并不重复， as well修饰的是and后面的谓语动词buy(类似见prep 2-166补充说明中对but instead的说明);Only做adj.修饰basketball

　　E. shoppers和department stores不对等;shop impulsively very little错误同B;they没有指代;only放在a basketball前强调含义改变，同B
