首先很抱歉几乎所有的题目答案我都不确定。大家见谅。

will add more if i can recall more.

RC:

1. black workers moved from rural south to urban north, joined union then quit. Mr. Grossman tried to use Mr. xxman's model to explain, but unwarranted. the central idea is: the unions were controlled by different ethnic groups, but not class-based. black workers joined but dissapointed.

old JJ.

2. drug delivery system: back to 1961 some guy used liposome to deliver drugs to the targeted cells.

remember: a. liposome is too large to pass the cycular wall(?). b. focus on the details, maybe take some quick notes along the way.

3. potatos cultivation in some south americas countries.

科学家们用了试验田方法鼓励农民们中新品种，但是农民伯伯们试了以后全都种回老品种（有题问what was the most likely happened when peasants tried the new variants)

解释了威慑么。高地农民比较富，大概以前中鸦片法了财，所以现在只中红皮的，价钱买的贵。但是投入也大。低地比较平穷所以大家要产量高的白皮。

题目忘了。不难。

forgot another RC. will add later.

SC: not much to say, plus SC is my worst i believe.

1. decide on...

in general, parrallelism is important.

CR:

1. bf: (under lab condition, fruit flies with certain enzyme can distinguish certain ordor which does not exist in the field). However mutant fruit flies cannot... Therefore (it is clear that enzyme cannot be the reason。。。余下记不清了）. most of the scientists agree that enzyme helps the memory buildup, but not specifically recognize the odor.

ask for relation, i chose the longest one, but don't know whether it's right or wrong.

still trying to recall more....
