例句：?Imissedtheschoolbusbymistakethismorning.

今天早上我無意中錯過了校車。?Itookyourpenbymistake.我錯拿了你的鋼筆。LanguagePoints【拓展】

mistake還可以構(gòu)成短語：

makeamistake/makemistakes犯錯誤；

mistake…for…把……錯認(rèn)成……。例句：?Don’tmakemistakesanymore.別再出錯了。?ImistookherforourEnglishteacher.

我把她錯認(rèn)成我們的英語老師了。2.Thecustomerthoughtthepotatoeswerenotthinenough.顧客認(rèn)為土豆不夠薄。單詞enough修飾名詞時，不需要倒裝.如:我有足夠的錢。餐廳里的食物不太夠。?Thereisn’tenoughfoodinthedinninghall.其修飾形容詞、副詞要倒裝。?Hewrotecarefullyenoughtogettheawardofthecompetition.Ihaveenoughmoney.enough常可以和詞組so-that，too-to轉(zhuǎn)換。如：他跑得不夠快，趕不上其他人了。用enough?Hedidn’trunfastenoughtocatchupwiththeothers.用so-that?Heransoslowlythathecouldn’tcatchupwiththeothers.用too-to?Herantooslowlytocatchupwiththeothers.3.Thecustomerwashappyintheend.
