Though subject to the same wild-animal control efforts that killed off almost all the wolves in North America over the past century,  the coyote’s amazing ability of adapting to the presence of humans has enabled it to expand its range into Alaska and Central America.1

请教为什么 coyote 前面though subject to 不是subjects to  ？

    我选C

    我想可能是因为be subject to，省略主胃

当然是这个原因了，否则怎么可以省略主语？

状语从句引导词词 + （主+系 － 可省略，但要省必须同时省）+ 形容词/分词，主+谓+宾。

噢~~~~~~~~~耶！

非常感谢。

be subject to

再问一句，好像也有subject to  这样用法的吧。 意思一样吗？

They denied a report that Egypt had agreed to a summit,subject to certain conditions. 介词短语：在...条件下。

google了一篇讲解，我想这里应取以下第一个意思：

"对中国学生来说，be subject to是个难点。它有三个意思。

　　1一是be likely to be affected by sth,especially sth bad or unpleasant，相当于“容易遭受…”和“容易受…影响”。例如：肥胖者容易得心脏病。Obese people are subject to heart attacks.

　　2 be subject to sth的第二个意思是be dependent on sth in order to be completed or agreed，相当于“取决于”和“视…而定”。例如：这篇文章准备好了，可以发表，就等你同意了。The article is ready to publish, subject to your approval.

　　3 be subject to sth的第三个意思是be under the authority of sth，相当于“服从于”、“受…支配”和“受…管辖”。例如：警察也须遵守法律。The police are also subject to the law."
