We shouldn't make noise here.(改成肯定陳述句)
We should keep quiet here.
肯否定變化規(guī)律：
先找到句子的謂語動詞,含有情態(tài)動詞、助動詞、be動詞時,可用該動詞形式的合適形式；不含有時,需根據(jù)謂語動詞判斷出所需要的情態(tài)動詞、助動詞、be動詞形式,然后變化.例如：
Tom 【works hard單三式謂語,表明助動詞用does】 at his lessons.變?yōu)榉穸ň?br/>——Tom 【doesn't 】work hard at his lessons.
這里原句中有【shouldn't make 】,表明要用情態(tài)動詞【should】.
He doesn't know how to get to the cinema.(改為同義句)
He doesn't know how he can get to the cinema.
or
He doesn't know the way to the cinema.
