雅思口语中用于过渡的万能犹豫句

　　在口语考试的时候,为了不影响流利渡,同时还不能出现silence挑战考官的耐心,而且要给自己思考留出喘息之机,我们往往需要一些话来过渡.这个话的长短视你需要思考的时间而定,下面这段大约30秒:
　　This is a tough question. I have never heard about it, nor have I ever read about it (倒装句丰富句型). Now you want me to talk about it. But I don't have too much to say. Give me a few seconds for me to search every piece of information in my head now.
　　它有一个变体,注意:突出标注的部分不同:
　　This is a tough question. I have never thought about it, nor have I ever read about it (倒装句丰富句型). Now you want me to talk about it. But I have too much to say. Give me a few seconds for me to organize my thougth a little bit.
　　你当然还可以自己根据上面的思路去编造一些其它的说法,以免雷同.
