几道高中英语语法填空?
1,she was offered a job in another town ,which is about 120km away .she __（move ）there after a week or so .
这题的答案是would move ,为什么我的was moving 不行呢?move 不是要用现在时表将来吗?
2,in June,2010,intense heat was blamed __about eighty deaths in India.
这里用哪个介词?为什么?
3,several hot days __follow each other are considered a heat wave.
这里应填什么?我一点头绪都没有.
还有,像这些没单词只有一个空的语法题怎么分析阿?我总是错这些题.
万分感谢您给具体的答复!快期末了,上次英语第一次上130,这次不想又跌120.
