赞同两位的解答。对于网友的追问,再提供一个例句:The effect on our blood chemistry is such that it produces physical changes in our entire body.我们血液的化学成分所受影响很大,致使全身都发生变化。▲再作一点补充。such用作代词位于句首作表语时,其谓语动词的单复数形式须根据主语而定。例如:Such is the texture of Persian history.这就是波斯历史的梗概.Such are the most powerful voices of our times! 这些就是我们时代的最有力的声音!
