全套2016年秋人教版八年級英語上冊Unit 10同步練習(xí)題及答案.rar,全套2016年秋人教版八年級英語上冊Unit,10同步練習(xí)題及答案,全套,2016,年秋人教版八,年級,英語,上冊,Unit,10,同步,練習(xí)題,答案 單元語法小專題(Grammar Focus) 語法精講 if引導(dǎo)的條件狀語從句 條件狀語從句通常由連詞if引導(dǎo)，意為“如果；假如；倘若”，表示在某種條件下，很可能會發(fā)生某種事情或不發(fā)生某種事情。 1．if條件狀語從句的位置 在 if 引導(dǎo)的條件狀語從句中，if 條件句位置比較靈活，可放在主句前面也可放在主句后面。若放在主句前，從句后面要用逗號和主句隔開。如： If he doesn't feel tired，he will visit the museum.＝He will visit the museum if he doesn't feel tired.如果他不感覺累，他就去參觀博物館。 2．if條件狀語從句的時態(tài)搭配 (1)當(dāng)主句用一般將來時，if 引導(dǎo)的條件狀語從句要用一般現(xiàn)在時。如： If it rains tomorrow，I won't climb the hills.如果明天下雨，我就不爬山。 (2)當(dāng)主句中含有can，may，must等情態(tài)動詞時，if 引導(dǎo)的條件狀語從句要用一般現(xiàn)在時。如： We can win the basketball game if he joins us.如果他加入我們，我們就能贏這場籃球賽。 (3)當(dāng)主句是祈使句時，if 引導(dǎo)的條件狀語從句要用一般現(xiàn)在時。如： Help your mom with the housework if you finish your homework early.如果你完成作業(yè)早，就幫你媽媽做家務(wù)。 if條件狀語從句用法歌訣： if 條件句不一般，幾個要點記心間； 條件句，放在前，逗號要放句中間； 條件句，表可能，主句多用將來時； 條件句，表事實，主句常用現(xiàn)在時。 3．與其他句式之間的轉(zhuǎn)換 (1)借助“祈使句 ＋ and/or ＋ 一般將來時的句子”這一句型來轉(zhuǎn)換。and在句意上表示順承關(guān)系，or表示轉(zhuǎn)折關(guān)系。如： If you get up early，you'll get there on time.＝ Get up early，and you'll get there on time.＝Get up early，or you won't get there on time.早點起床，你就會準時到那里。 (2)借助介詞without或with來轉(zhuǎn)換條件狀語從句。如： If there is no water，fish will die.＝Fish will die without water.如果沒有水，魚就會死。 If you help me，I'll finish the work soon.＝With your help，I'll finish the work soon.如果你幫助我，我就會快點完成工作。 (3)if … not引導(dǎo)的條件狀語從句，可以借助連詞unless來改寫。如： You will be late if you don't go there by bus.＝Y(jié)ou will be late unless you go there by bus.如果你不乘公共汽車你就會遲到。 語法精練 　　　　　　　　　　　　　　　　　　　 Ⅰ.用括號內(nèi)所給單詞的適當(dāng)形式填空。 1．If it rains tomorrow，I ________(stay) at home. 2．He will take a trip to Beijing if he ________(be not) busy next week. 3．Please tell Li Jun about it if he ________(come) back. 4．If you don't wear your school uniform to the party，the teachers ________(not let) you in. 5．She ________(not go) shopping with her parents if it snows this afternoon.
