question the notion that customer loyalty program are beneficial; the passage gives a lot of counterexamples which suggest that the program is not as beneficial as companies and advocates think
错选E：“定语从句that won the Nobel Prize for Literature应改为不定式短语to win the Nobel Prize for Literature，这点考查了不定式和从句的区别，用之于本题，“变成第一位女性和第一位瑞士作家”会直接影响“赢得诺贝尔奖”这一事件的发生与否，因此应该用不定式短语。”
turn away from... to ...不是turn away from...and...
要注意细小词汇的转换！！！
idiom: not so much X as Y
In A, D, and E “…not so much X but Y…” is not idiomatic.
Always use "like" as a preposition, never as a subordinating conjunction.
EXAMPLES:
错误：My face felt like it had been set on fire.
正确：My face felt as if it had been set on fire.
The use 不能 like electromagnetic waves
这句话的意思是重力波不和别的东西反应（which修饰的是重力波不是use），用like的意思是不和e波反应，用in balabala意思是是用这个e波的话e波会和别的东西反应
like 离 matter 太近了，产生 matter like electromagnetic waves的歧义
原文表达的是以什么方式 而不是像
it is hoped 表客观，ETS prefer
hopefully 表主观，GMAT中一般为错误选项
hopefully meaning "i hope that/let's hope that". This is an informal expression, and is generally avoided in writing.
contrary to：考点，强对比，取非：McKay's team has demonstrated that the concentration of PAH's increases as one looks deeper into ALH84001, contrary to what one would expect from terrestrial contamination.
错选B：“who plan on practicing in socioeconomically deprived areas是定语从句，修饰other graduates，其使得主干的结构变为：
minority graduates are nearly four times more likely than other graduates
这句话只讲了少数毕业生比其它毕业生有更大的可能性，但是可能去干什么呢？没有写明，所以本句是错误的，不能说“人”比“人”更可能，只能说什么事情发生的可能性。“
