走过路过的都来看看，OG13-sc-26

26. Tropical bats play important roles in the rain forest ecosystem, aiding in the dispersal of cashew, date, and fig seeds; pollinating banana, breadfruit, and mango trees; and indirectly help produce tequila by pollinating agave plants.

(A) pollinating banana, breadfruit, and mango trees; and indirectly help produce

(B) pollinating banana, breadfruit, and mango trees; and indirectly helping to produce

(C) pollinating banana, breadfruit, and mango trees; and they indirectly help to produce

(D) they pollinate banana, breadfruit, and mango trees; and indirectly help producing

(E) they pollinate banana, breadfruit, and mango trees; indirectly helping the producing of

关于E的解释不太明白，OG13认为此项是平行的，错点在help的用法上应该改成helping to produce。

为什么这项是平行的呢？ they pollinate banana没有破坏平行吗？ 困惑呀~

我觉得是(E)选项写错了，这题核心就是考平行，其他都是trivial。你看OG解释的第一段就详细说了为什么必须是(B).
btw: OG解释精华往往在第一段，关于错误选项的解释经常很敷衍

问题：

Only seven people this century have been killed by the great white shark, the man-eater of the movies—less than those killed by bee stings.

A. movies—less than those

B. movies—fewer than have been

C. movies, which is less than those

D. movies, a number lower than the people

E. movies, fewer than the ones

之前看了你的帖子，说，如果这里是作定语Killed应该是having been killed，还有下面这道

According to United States Air Force officials, a cannon shooting dead chickens at airplanes has proved helpful to demonstrate what kind of damage can result when jets fly into a flock of large birds.
(A) shooting dead chickens at airplanes has proved helpful to demonstrate
(B) shooting dead chickens at airplanes has proved itself helpful as a demonstration of
(C) shooting dead chickens at airplanes proves itself helpful as demonstrating
(D) that shoots dead chickens at airplanes proves itself helpful to demonstrate
(E) that shoots dead chickens at airplanes has proved helpful in demonstrating

看了您的讨论总结，说，A cannon shooting 实际上是 a cannon that is shooting

这里补充了that be，我不明白的是怎么确定补充的be动词的时态的？

希望能被看到！

"这里补充了that be，我不明白的是怎么确定补充的be动词的时态的？"


v-ing本身只是表示progressive，时态取决于所处的句子的时态，也就是“大环境”。


The man talking loudly was Mr. A.   (Mr. A was talking loudly)
The man talking loudly is Mr. A.   (Mr. A is talking loudly)
The man talking loudly will be Mr. A.   (Mr. A will be talking loudly)

"having been killed"道理一样的。
注意：句子的大环境是现在！即我们处在的time frame是现在。那么这句话咱如果正常说，会说：people have been killed ... （从现在的眼光看过去）
那么你把"have been killed"换成noun modifier，就成了"people having been killed"

yeah,明白了！ 一致忽略了分词还有不同时态形式。如果说修饰部分存在的时态与整个句子的环境不一致，就要改成that从句
还有像although+ving这样的形式，如果补上be以后，时态不合语境，就不能用ving，分词补上后都成了进行时~

ps：一上来就看到回帖，特兴奋！哈哈~太感谢了！

哪种苦不苦

问题：Only seven people this century have been killed by the great white shark, the man-eater of  ...

这道题的关键在于helpful的用法。be helpful in doing在某方面是有用的。be helpful for sb to do sth，而本题中并无forsb to do 这个意思

之前看过讨论贴说 noun having been done这种形式是不对的 having been done无法做noun modifier people having been killed是不是不正确呢？ 望解答~~~
