Question

1．一有人求助，他就會(huì)伸出援手．
He will give a handas soon as someone asks for help．

Answer 1

分析 as soon as someone asks for

解答 答案：as soon as someone asks for．表示一…就用as soon as引導(dǎo)的條件狀語(yǔ)從句，遵循主將從現(xiàn)的規(guī)則，從句主語(yǔ)someone，謂語(yǔ)動(dòng)詞用單數(shù)，ask for help求助，故答案是as soon as someone asks for．

點(diǎn)評(píng) as soon as 的用法一般是兩種情況：
1、指未發(fā)生的動(dòng)作，規(guī)律是：主句一般將來(lái)時(shí)，從句用一般現(xiàn)在時(shí)代替一般將來(lái)時(shí)
如：I will tell him the news as soon as he comes back．
注：有時(shí)，為了特意表達(dá)剛剛完成某事就如何如何，需要用現(xiàn)在完成時(shí)．
如：I will go with you as soon as I have washed my face．
2、指緊接著發(fā)生的兩個(gè)短動(dòng)作，主從句都用一般過(guò)去時(shí)
如 He took out his English books as soon as he sat down
不過(guò)，我也見過(guò)從句和主句都用一般現(xiàn)在時(shí)的情況．
