1)If city noises ___from increasing,people will have to shout to be heard even at the dinner table 20 years from now.
A are not kept B do not keep
2)Jane was made ___the truck for a week as a punishment.
A to wash B to be washing（to be doing是什么意思）
看我说的对不对：keep from的被动是be kept from
be made to do 被要求做某事 be made to be doing被要求一直做某事，这里是for a week 持续的一段时间 所以用be made to be doing 所以选AB
答
1.a2.b噪音应该是人为的阻止增加，所以要用被动语态2.主动语态中省略的介词在被动语态中要还原
答
1.A
2.A
1.用被动语态
2.还是被动语态,made用被动语态要加to
to be doing是进行时，因为后面有for a week所以选A
答
1.A 噪音和制止是被动关系,A表示被动
2.B be made to do被指使作某事
be made to be doing是被指使一直坐某事
这里说洗一周卡车,表示持续,所以选B
答
a
be kept from 是远离 的意思。。被动
a
b语法不通 make to do 是让某人做某事
