c里的having down 有错吗，是用完成时吗

就这样默默地被迷惑了，选了C.....

B 需要和and前面部分并列，最后不能有it，而且没有先行词。

也就是从that开始到pronounced之前，都是从句。把从句去掉就是a work pronounced....

以前一直不明白OG里面无关的意思.....今天终于终于弄懂了......感谢老师！！！！！

C累赘但是没有错呀。而且A看起来还缺少一个in，but sales (In) this past Nov

答题关键：others of the closely related group of plants 根据原文来看是只其他也在重金属土壤中存活的植物，其实此题相当于变相考察了定语从句修饰问题。

在E中 “The greatest road system built in the Americas prior to the arrival of Christopher Columbus was the Incan highway” 是不是 “ the Incan highway” 的同位语？

(B)news of these shots that was sent by swift messenger took four days
took的动作发起者是不是歧义？（news／messenger）
能否当成错误原因？

a.b.c是overseas的定语，d.e是状语修饰这个register的动作显然不对；a.b.选项里的their显然不对，这里的逻辑应该指代company是单数。

(C) "had been released": passive voice, which could be OK, but we don’t really need it here. Generally, stick with active unless you need passive voice, or unless the other choices all have other errors.

The form of the word "release"
(A) "the release": This is OK, as it is a noun. "...35 years after noun (the event, in this case the release of bees)
(B) "releasing": The -ing form makes the entire phrase a modifier. It forces us to ask and answer the question "WHO released the bees?" The answer must follow the comma after the modifying phrase, but instead of a logical bee releaser (people), we find the bee’s descendents after the comma.

请问为什么A不对呢？他说V卖出4000，然后租的比卖的多，那不就说明V 的租赁抢了C的租赁吗？

prospect约束力强，所以用to do 对吗？

E选项省略了啥。。。

a b c 的of being为什么错了呢

F物质最初是在实验室里发现的，但后来在自然界的某石头S的缝隙里也发现了F物质。
因为在实验室合成F物质需要特殊的温度和压力，所以能以此来推断自然界当年形成F物质的地质状况。

Records from ancient Athens indicate
that each year young Athenian women collaborated to weave a new woolen robe with
which they dressed a statue of the goddess Athena and that this robe depicted scenes of a battle between Zeus, Athena's father, and giants.

it 指代的是什么呢
