1..You aren't a stranger,are you 你不是一個陌生人,是嗎?
肯定回答,我是一個陌生人.yes,i am.
否定回答,我不是一個陌生人.no,i am not.
記住,回答反義疑問句,按實際情況回答,和怎么問的沒關(guān)系.
變式：you are a stranger,aren't you
回答也是一樣的,按實際情況回答.
肯定回答,我是一個陌生人.yes,i am.
否定回答,我不是一個陌生人.no,i am not.
2..why not do sth,why don't you do sth
例句why not go for a movie?why don't you go for a movie?
3.contribution to ding .to是介詞,后跟動名詞.
拓展：contribute to sth.=contribute to dong.=make a contribution to sth.=make a contribution to dong
4.speaking是主動的,動名詞兼現(xiàn)在分詞.spoken是被動的,過去分詞.
典例：Speaking English is very important.( 動名詞做主語）
Native speakers speaking English know the saying( 諺語)well.(現(xiàn)在分詞人作主語）
English spoken in Canada is quite different from that spoken in America.(過去分詞物作主語）
