Forget the given answers to those SC.
1. A, 2.B, 3. E, 4. B

不是很明白这些选项为什么正确．

gigi

1,是属于习惯搭配，其他的既不简洁，也不符合习惯用法。

gigi

2、c. relations between nations that illustrate
关系是很多nations 之间的不能用between
d. relation of one nation with another and illustrate
twist了句子本身要表达的含义不应用and 连接
e. relations of nations that illustrates
没有b指代的意思清楚是一个国家和另一个国家之间的关系
你觉得选哪个好呢？

1. at the invitation of:应...邀请 (固定搭配)
2. A nations that illustrates单复数错,B relation...illustrates对,C between nations ...and treaties...不通,D recounted...and illustrate...错, E 同A
3. The Madagascar periwinkle ... is cultivated 对,derivative延生物,不能被cultivated
4.未画线部分有you,A错,B简洁

gigi

4、e. a written description of your purchase is what should be asked for
不好意思，要落俗套的说是要主动优先被动

THANKS!!
No.2: 是不是两个以上用AMONG,两个及以下用BETWEEN? 例如:The difference between these 2 guys is obvious. The difference among those three guys is obvious.
BTW, 你门是怎么一眼看出NATION和TREATY搭配不对?我一上来看到BTWEEN就去找AND,结果上当受骗.

jjjjjj

3. 为什么derivative延生物,不能被cultivated??
4. 因为句首有WITH　ＤＩＡＭＯＮＤ，　我怎么觉得和a written description （而不是正确答案里的ＹＯＵ）搭配更好呢？

gigi

JJJJ:2、你的理解是正确的。
4、吃的不是很准，WITH 在这作什摸成分，伴随吗？是不是建议的口吻“对于钻石，珠宝之类，你要要个描述的保证书之类”
3、我理解句子要说The Madagascar periwinkle,IS CULTIVATED NOT a derivative

3 E 是指一种植物(M)的衍生物对病人有好处,所以这种植物被种植.C 是说...,所以这种植物的衍生物被种植.不如E的意思好.有的时候语法上有难度就从意思上找一个说的顺的.
4 我看见过这里好象有一片文章是专门讲WITH的用法的,你不妨找一下看看.我也讲不明白,感觉就是B好
