The car knocked the bike over.汽車把自行車撞倒了。 The child knocked his head against the wall.那小孩把頭撞在墻上了。 The cow knocked down a small tree and ate the leaves.那頭牛把一棵小樹撞倒了,把樹葉吃了。 3.The soil should also be turned over with a fork so that the weeds would be de-stroyed.還應當用耙子翻地,以除掉雜草。 1)turn over的意思是“翻轉(zhuǎn)”。例如: The doctor turned him over and looked at his back.醫(yī)生把他翻轉(zhuǎn)身來看看他的背部。 When the telephone rang,he just turned over and went to sleep again.電話鈴響的時候,他翻了一下身,又睡著了。 2)關(guān)于turn的用法小結(jié)。 A.不及物動詞,作“轉(zhuǎn)動、轉(zhuǎn)身、拐彎”解。例如: The wheel turned slowly.車輪慢慢地轉(zhuǎn)動。 B.及物動詞,作“轉(zhuǎn)動、翻動”。例如: He turned his car to the left.他把汽車向左開。 C.連系動詞,作“變得”。例如: The leaves turn yellow in autumn.樹葉在秋天變黃。 D.構(gòu)成短語。 turn on/off開/關(guān)(電燈,收音機);turn into變成,譯成;turn out關(guān)掉,熄滅;turn to翻動,轉(zhuǎn)向 4.Do not plant,for example,rice year after year in the same field.例如,在同一塊地里,不要年復一年地種稻谷。 year after year是“年復一年地”意思,表示每年重復。例如: We used to go to the mountain village for a holiday year after year.我們以前年年都去那個山村度假。 Year after year we have had a Christmas card from Dick.我們年年都收到迪克寄來的圣誕卡。 注意,還有一個詞組year by year的意思是“逐年(變化)”。例如: The boy grows taller year by year.這男孩長得一年比一年高了。- 1.請仔細閱讀文檔,確保文檔完整性,對于不預覽、不比對內(nèi)容而直接下載帶來的問題本站不予受理。
