6、, 這在英語里被稱為“主將從現(xiàn)”。 主句的將來時態(tài)并不僅限于我們這一課里所學習到 的will動詞原形構成的一般將來時, 還包括be going to動詞原形、be doing所表示的一般將來時 以及我們以后會學到的其它的將來時態(tài)。例如,what is he going to do when he grows up? 他長大了想干什么？ we are leaving for amoy tomorrow if it doesnt rain. 如果明天不下雨, 我們就去廈門。 we will buy that microwave next week if its price keeps going

7、down. 如果價格持續(xù)下降, 下個禮拜我們就買那臺微波爐,if +, ill / youll +,條件,結(jié)果,for example: if you study, ill be happy. wear jeans to school , youll be sorry. get up late, youll be late. eat too much, youll be fat. wash your clothes yourself,1. structure,這里if所引導的是真實條件句(real conditional), 即所 假設的條件有可能成為現(xiàn)實, 表達假定所假設的條件 實現(xiàn)時會出現(xiàn)

8、的情況或會采取的行為。有時, 我們 可以使用并列結(jié)構的祈使句來表達這種類型的條件句。 e.g. if you set your alarm clock, you wont oversleep. 如果你上鬧鐘, 你就不會睡過頭了。 set your alarm clock, and you wont oversleep,if you give him an inch, he will take a mile. 他會得寸進尺。 give him an inch, and he will take a mile. if you dont give him some food, he will sta

9、rve. 如果你不給他一點吃的, 他就會餓死。 give him some food, or/else he will starve,1)條件狀語從句通常由連詞if引導, 意為“如果、假如”, 主句不能用be going to表示將來, 而應該用shall、will。e.g. if you leave now, you are never going to regret it. (錯誤) if you leave now, you will never regret it. (正確) (2) if “如果”, 引導條件狀語從句, 主句用一般將來時， 從句則用一般現(xiàn)在時，如：if it rain

10、s tomorrow, i shant climb the hills,2. 用法,注意: 賓語從句中的if與條件狀語從句if的區(qū)別。 賓語從句中的if “是否”相當于whether, 引導 賓語從句, 時態(tài)需根據(jù)語境確定。i dont know if it will rain tomorrow. 我不知道明天是否會下雨,在閱讀英文文章時, 我們有可能看到這樣的句子： if my father will give me permission, i shall spend a few months abroad. 如果我父親同意, 我將在國外待幾個月。 if you will take the

11、trouble to read his letter carefully, you will see what he means. 如果你肯花一些時間來認真讀他的信，你就會明白 他是什么意思了。 在if-分句中中用“will動詞原形”并不單純表示將來意義， 這里的will是個表示“意愿”的情態(tài)動詞, 相當于be willing to (愿意,要注意這種帶“will動詞原形”的if-分句在某些場合 是不可以隨便用的, 比如我們可以說： if he gets my letter in time, hell be able to change his plans. 如果他及時收到我的信, 他就能改變

12、他的計劃。 卻不可以說成： if he will get my letter in time, hell be able to change his plans,另外, 在if-分句中還可能使用“would動詞原形”的結(jié)構， 這種用法還是表示“意愿”, 常用于表示客氣的請求, 這時 主句動詞既可以用will/ shall動詞原形, 也可以用would/ should/ could/ might動詞原形。如： if you would try italian food, you would like it. 如果你愿意嘗嘗意大利食物, 你會喜歡它的。 if you would reserve t

13、he seats, we would be sure of a comfortable journey. 如果你愿意訂座, 我們將肯定會有一個舒適的旅程,1.如果你不趕快走, 你就會遲到。 2 .如果你愛你的父母, 你應當幫他們做做家務。 3. 如果你更友善一些, 你會教上很多好朋友,exercise,if you dont go soon, youll be late,you should help do the housework if you love your parents,you will make lots of friends if you are more friendly,

14、4.如果你帶外校的朋友來, 老師會讓他們離開。 5. 如果你不完成作業(yè), 媽媽不會讓你玩電游。 6. 當你看到bill gates, 你會對他說些什么,if you bring friends from other schools, the teacher will ask them to leave,if you dont finish your homework, your mother wont let you play computer games,what will you say to bill gates when you see him,for more exercises,

15、click here,1. bedoing形式: 用現(xiàn)在進行時態(tài)表達將來， 主要意義是表示按計劃、安排即將發(fā)生的動作， 常用于位置轉(zhuǎn)移的動詞, 如go、come、leave， start、arrive等, 也可用于其它動態(tài)動詞。如： the president is coming to the un this week. 總統(tǒng)這周將到聯(lián)合國來。 we are moving to a different hotel the day after tomorrow. 我們后天將換一家賓館,language points,在現(xiàn)在英語中, 有相當多的動態(tài)動詞都可以用 現(xiàn)在進行時表示將來。例如： dinn

16、er is ready. were having fish for dinner. 晚飯好了, 今晚我們吃魚。 im spending my holidays in singapore this year. 今年我要去新加坡度假。 tom isnt finishing his high school until next year. 湯姆明年才高中畢業(yè),advice意為“勸告；建議”是不可數(shù)名詞，不能說 a advice, 而是a piece of advice,也因為advice是不可 數(shù)名詞。“兩個（則）建議”，我們通常說 two pieces of advice。注意piece要采用復數(shù)

17、， advice不可數(shù)，但piece可數(shù)。我們也可以說為 some pieces of advice一些建議。 如：can you give me some advice? 你能給我一些建議嗎,2. can you give me some advice please,與advice有關的一些詞組： ask advice of 向.征求意見, 請教 by sb.s advice 依某人勸告 on sb.s advice 依某人勸告 follow sb.s advice 接受某人意見 give advice 勸告, 忠告,dear su mei, i dont _ (know) what to
