If引導(dǎo)條件狀語(yǔ)從句

語(yǔ)法專練：1/15位置：從句可放在主句之前或之后，不過(guò)放在主句之前須有逗號(hào)隔開eg:假如我有足夠錢，我就去周游世界定義：if

“假如,假如”它引導(dǎo)句子表示某事發(fā)生所需條件，即“在…條件下，某事才能發(fā)生”，在句子中充當(dāng)狀語(yǔ)，所以稱之為條件狀語(yǔ)從句。（If引導(dǎo)條件狀語(yǔ)從句表示假如有從句動(dòng)作發(fā)生，就會(huì)有主句動(dòng)作發(fā)生）IfIhaveenoughmoney,Iwilltravelaroundtheworld=IwilltravelaroundtheworldifIhaveenoughmoneyIfitrainstomorrow,Iwillstayathome.一、什么是條件狀語(yǔ)從句？2/15使用方法：1.
