Now many cities in China ____ water pollutiona.are prohibited b.are warned of选B A错哪呢?

问题描述:

Now many cities in China ____ water pollution
a.are prohibited b.are warned of
选B A错哪呢?

B是被警告
A是被阻止
水污染不能阻止的,只能警告,这是根据意思选的题

b
a选项后面应该加to do sth.

如果想说水污染在城市中被禁止,应该这样说:
Water pollution are prohibited in many cities in China now.
如果用cities are prohibited,是“城市被禁止”的意思,不通.
B:现在中国的许多城市被警告存在水污染现象.

A是禁止
B是警告
当然,水污染是不能被禁止的,只能通过警告来最小化
