比较
1. more + …rather than/ instead of/ compare with/ comparison with …错，有more有比较 就有than，T254; 有than 就有比较T106
2. 注意比较的对象T268
3. 要么as...as..要么more than而不要混用
4. 主句从句对比时，尽量保持平行T188
5. 名词1+动词+介词+名词2的结构，如果有对比，如higher than…/ in the same way as …/instead off…+ X，其中X部分通常有两种形式：名词3+动词以表示名词3与名词1对称; 或介词+名词4以表示名词4与名词2对称.
…formulas for cash flow and the ratio of debt to equity do not apply to them (指new small business) in the same way as to established big business
6. than usual/ than ever before(T98)为习惯表达，如 the weather is wetter than usual.. fficeffice" />

2. 代词要有明确的指代对象T35，T42，T43
3.there，where，those，these，they，its，出现时，也要有明确的指代对象，并且该对象不能出现在定语成分中T38，T80，T181
4. 动词后面用来指代一个动作只能用so，如think so，do so. T41, T215
6. 注意复数对应复数T61，T97. eg. Iguanas are still prized as game animals
7. 指代前面提及的examples or instances时，用such而非theseT116.
8. do 可以代替动词不定式，如 T129，their wines are priced to sell and they do (代替sell)

还是有一定价值的

61. 定语从句尽量紧跟被修饰成分，T113，T117 A of B + 定语从句/过去分词短语(C)做定语结构中，首先考虑C修饰紧接着在其前面的名词，即C从语法上首先考虑修饰B，再则考虑修饰A，T109, T229
The colorization of black-and-white films by computers is defended by those who own the film rights, for the process can mean increased revenues for them; many others in the film industry, however, contend that the technique degrades major works of art, which they liken to putting lipstick on a Greek statue.

62. 注意词序对句意的影响：more gasoline –efficient cars / cars more gasoline-efficient T112
66. unlike，besides，other than 位于句首，则修饰主句主语.
68. 比较develop independently from a 与develop independently of a 之间的区别T143.
69.句子强调的重心应该保留T153
70. a of b，中心词为a
71. 介词短语放在一个名词之后，则直接修饰该名词
72. 注意定冠词与不定冠词、物主代词的区别
仔细体会：50 genes in a cell/ 50 genes in the cell/ the 50 genes in cells/ 50 genes in cells T176
注意the hands 与his hands的区别，一般表达使用所有格形式T86. the 表示上文已经提及的对象（体会a man 与the man的区别T54），such也表示上文已经所有提及T106，T181
75. as…as 位于句首应与主句主语一致，且表现前后比较，as…as 表示让步，如：as ill-prepared as they are，they nevertheless find good jobs. T177
76. 现在分词与过去分词做定语时候的区别，现在分词表示一个正在进行或持续进行的动作，而过去分词表示一个已经结束或被动状态的动作：T210 that 从句与现在分词短语修饰，区别在于一次性/ 多次性，连续性T178；that 从句与过去分词短语修饰，无意义差别，一般选用过去分词
One of Ronald Reagan’s first acts as President was to rescind President Carter’s directive that any chemical banned on medical grounds in the United States be prohibited from sale to other countries.
(A)that any chemical banned on medical grounds in the United States be prohibited from sale to other countries

79. since (then …) 要用完成时态
80. yet，but 等连词连接独立句子时，前应该有分号T184
81. 多动词结构，特别是有被动语态时，应该保证最后一个动词的逻辑主语明确 T171，T181，T183
82. 被动语态加动词不定式，则不定式逻辑主语为被动语态动作发出者 T183.
85. 动词 + 宾语 +that从句为错误的表达，应为动词+that从句 T61 fficeffice" />

frankdong

简洁
1. never regain again重复错误.T246
2. 虚拟语气中的should一定要省略
3. 句子中不得有重复的成分，如soaring与rise/ increase/ grow/ raise等，amount to a sum 其中a sum就多余 T101，annual 与a year重复T110
4. n + that is + adj. 为wordy的表达，正确的是：过去分词/ adj.+ 名词，T34，T151. 如dioxins that are currently uncontrolled 应为currently uncontrolled dioxins
5. not any 应改为no，T59
6.主语加两个动作，如果两动作有同一主语，则两个动作并列，不能在第二个动作前重复主语 T65
84. at one time -> onceT188fficeffice" />

没有歧义
1. A+修饰短语（如现在分词短语）+B，如果修饰短语既可以修饰A又可以修饰B，则有歧义，错.T245，T179
34. sb.1 and sb. B + 定语从句，要明白定语从句到底修饰哪个，可以考虑使用sb.1 +定语从句 and sb.2的形式来解决.T27
53. increase twice有歧义T72 (两倍/两次)
64. a of b and c ，有歧义，T128.

(A)in part that their steers should acquire certain characteristics
(B)in part for the acquisition of certain characteristics in their steers
(C)partly because of their steers acquiring certain characteristics
(D)partly because certain characteristics should be acquired by their steers
(E)partly to acquire certain characteristics in their steers
5. 从划线部分推断未划线部分的结构/意义/形式，如系平行结构T8，T169
6. 需要用平行结构的短语：rather than (其后不定式to 可以省略)，instead of..，as …，or ..(T138)，not X but (rather) Y (T172)，more X than Y
