几个关于英语的问题-初中英语
for many reasons这种搭配存在吗?A computer can do_____problems a few seconds.
填with on at 还是in?use of computers_____(is/are)growing.,
打错了 抱歉 应该是A computer can do millions of problems________a few seconds.这个填什么呢

Answer 1

for many reasons  由于种种理由/原因
直接填with就可以了,do with=deal with 解决 的意思
选is.这题的主语是use,所以用单数
