　　1.Thismuseumis()youvisitedtheotherday.

　　A.thatB.whichC.whereD.theone.

　　这道题为啥不能选D,而一定要选A?

　　2.Itisthethirdtime()latethismonth.

　　A.thatyouarrived.B.whenyouarrived

　　C.thatyou'vearrivedD.whenyou'vearrived.

　　我选的是D,但为什么正确答案是C呢?

　　3.Itwasin1969thattheAmericanastronautsucceededinlandingonthemoon.

　　这句句子是不是强调句的句型呢?为什么句中的that不能换成when?

　　暂且就问这三个问题了~虽然解释起来挺麻烦的,还是希望英语高手帮帮忙拉~明天纠错本就要上交了..
