18. Out ________, with a ruler in his hand. A. did he rush B. rushed he C. h
China has already sent up three spacecraft, the most recent at the end of last March.
A. has been launched B. having been launched
C. being launched D. to be launched
为什么选B
18. Out ________, with a ruler in his hand. A. did he rush B. rushed he C. hChina has already sent up three spacecraft, the most recent at the end of last March. A. has been launched B. having been launchedȽ
第一个题目我已经给你解释了!答案 he rushed
第二题:
the most recent [ having been launched] at the end of last March
此结构是[ 名词+ 分词短语] 的"独立主格结构"
因为前面China has already sent up three spacecraft 是个完整的句子,所以,在没有连词的情况下,后面不能选A 而成为一个句子.如果选A,后面的句子和前面的既不构成并列关系,又不是主次从属的关系.
