A.when B.while C.until D.though
3.( ) the temperature falling so rapidly,we couldn't go on with the experiment.
A.Since B.For C.As D.With

1个人觉得选A,about 后面跟名词,没见过跟从句,再说there be something 本身是倒装,正过来就是something is there,所以no on had told smith about a lecture being there the following day.2选A表示突然状况3选D,前...第3题再详细解释一下,可以吗?第三题,如果用FOR,SINCE 或者AS 的话,那么句子就是since/for/as the temperature fell so rapidly, we couldn't go on with the experiment. 因为他们是连词,必须跟一个完整的从句,用with 的话,可以把前半部分当成名词结构,with the temperature falling so rapidly,... 这里falling 后面的作定语修饰temperature.
