動(dòng)詞要加“s”.
順便給你講一下一般現(xiàn)在時(shí)的用法
1) 經(jīng)常性或習(xí)慣性的動(dòng)作,常與表示頻腮度的時(shí)間狀語(yǔ)連用.
時(shí)間狀語(yǔ)：every…,sometimes,at…,on Sunday
I leave home for school at 7 every morning.
2) 客觀真理,客觀存在,科學(xué)事實(shí).
The earth moves around the sun.
Shanghai lies in the east of China.
3) 表示格言或警句中.
Pride goes before a fall.驕者必?cái)?
注意：此用法如果出現(xiàn)在賓語(yǔ)從句中,即使主句是過(guò)去時(shí),從句謂語(yǔ)也要用一般現(xiàn)在時(shí).
例：Columbus proved that the earth is round..
4) 現(xiàn)在時(shí)刻的狀態(tài)、能力、性格、個(gè)性.
I don't want so much.
Ann Wang writes good English but does not speak well.
比較：Now I put the sugar in the cup.
I am doing my homework now.
第一句用一般現(xiàn)在時(shí),用于操作演示或指導(dǎo)說(shuō)明的示范性動(dòng)作,表示言行的瞬間動(dòng)作.再如：Now watch me,I switch on the current and stand back.第二句中的now是進(jìn)行時(shí)的標(biāo)志,表示正在進(jìn)行的動(dòng)作的客觀狀況,所以后句用一般現(xiàn)在時(shí).
