那个新东方和石林语法什么的怎么讲的有些都是不一样啊。。。
那个石林语法说try to错，但是下面这道题？
1.SC大全补充题250中的31题：
31.It may someday be worthwhile to try to recover uranium from seawater, but at present this process is phohibitively expensive.
A. It may someday be worthwhile to try to recover uranium from seawater.
B.Someday, it may be worthwhile to try and recover uranium from seawater.
C.Trying to recover uranium out of seawater may someday be worthwhile.
D.To try for the recovery of uranium out of seawater may someday be worthwhile.
E.Recovering uranium from seawater may be worthwhile to try to do someday
我选的是D,因为考虑了不能用try to。可是答案是A。。。求解
2.还有那个adj.+n>n.+that is adj.吗？为什么下面这道题不是啊？
补充题中的33题
33.The spraying of pesticides can be carefully planned, but accidents, weather conditions that could not be forseen, and pilot errors often cause much larger deposits of spray than thet had anticipated.

C.unforeseeable weather conditions, and pilot errors are the cause of much larger deposits of spray than they had.
D.weather conditions that are not foreseeable, and pilot errors often cause much larger deposits of spray than.
E.unforeseeable weather conditions, and pilot errors often cause much larger deposits of spray than they had.
我选的是E。可是答案是B。为什么啊？

try to 是错吗？石林我也看过，不过没有记得这么说过；倒是try for ，考试的时候看到那是必错无疑
C和A哪个好是个问题，我觉得C看起来也不错啊
2.还有那个adj.+n>n.+that is adj.吗？为什么下面这道题不是啊？
这个规则基本没什么用了，很多情况下都是用后者来避免歧义产生的
补充题中的33题
33.The spraying of pesticides can be carefully planned, but accidents, weather conditions that could not be forseen, and pilot errors often cause much larger deposits of spray than thet had anticipated.
A.weather conditions that could not be forseen, and pilot errors often cause much larger deposits of spray than they had.
B.weather conditions that cannot be foreseen, and pilot errors often cause much larger deposits of spray than.
C.unforeseeable weather conditions, and pilot errors are the cause of much larger deposits of spray than they had.
D.weather conditions that are not foreseeable, and pilot errors often cause much larger deposits of spray than.
E.unforeseeable weather conditions, and pilot errors often cause much larger deposits of spray than they had.

3.如果题目中出现的情态动词是perhaps,选项中出现may.是错的么？
4.read of 还是read about？

我觉得E的they had anticipated缺少一个宾语，应该为what they had anticipated才完整
read about 固定搭配
perhaps不是情态动词，而是副词；它和may同时出现的时候基本可以排除
一点拙见 希望有帮助 白林语法我也曾经研读过 期望走捷径 但是捷径的路是死路 现在的XDF应该已经不用石林的那套讲课了吧 不知道放在网上做什么用；反正我现在不太敢用石林里的语法规则做题了 不过不同的人不同看法
1.SC大全补充题250中的31题：
31.It may someday be worthwhile to try to recover uranium from seawater, but at present this process is phohibitively expensive.
A. It may someday be worthwhile to try to recover uranium from seawater.
B.Someday, it may be worthwhile to try and recover uranium from seawater.
C.Trying to recover uranium out of seawater may someday be worthwhile.
D.To try for the recovery of uranium out of seawater may someday be worthwhile.
E.Recovering uranium from seawater may be worthwhile to try to do someday
我选的是D,因为考虑了不能用try to。可是答案是A。。。求解
这里someday(at some times in the future)为副词,若放句首则改变句意所以B删
It虚主词放句首指代的是to recover动作
句意表述:从seawater recover uranium可能将来有一天是值得去尝试
Try to是错的????………PS我没看过这条规则…
至于D的错误:
1.有动词recover没必要用名词
2.犯了头重脚轻原则…ets还是偏爱小巧可爱的It做虚主词指代to的动作
Open to discuss…..
请问LS前辈
31题C的问题是？
31.It may someday be worthwhile to try to recover uranium from seawater, but at present this process is phohibitively expensive.
A. It may someday be worthwhile to try to recover uranium from seawater.
B.Someday, it may be worthwhile to try and recover uranium from seawater.
C.Trying to recover uranium out of seawater may someday be worthwhile.
D.To try for the recovery of uranium out of seawater may someday be worthwhile.
E.Recovering uranium from seawater may be worthwhile to try to do someday
我的理解：
1、C、D主语过长，应该用形式主语it来简化，然后用从句来详细阐述，这样的句子比较清楚
2、E里面最后的they指代不清
2.
they指代应该有歧义吧
另外,我在B跟D间犹豫,还是选了错误的D
是因为原句有could所以不能选D吗?
我看D有个foreseeable也带有可能的意思,所以选了他
可以指点一下D不优于B的理由吗?
补充一点:查了一下try惯用确实没看过try to的用法,
字曲上也普通使用to try的方式至于idiom: try on\for\out
我認為第一個問題除了大家討論的issue以外，是考recover from，我自己選的時候，是靠著這個線索
先刪除C,D.E錯的原因是worthwhile to try to do.wordy，可以直接說worthwhile to try to recover
所以剩下A,B.B由於someday在原句中是修飾be worthwhile,B把它提到句首變成時間副詞,有改變句意的嫌疑，加上it is...to指代清楚，it是指後面to ....所以我選A
想請教第二題為何不能選D?是wordy嗎？
