1. potato chips were invented by mistakes. mistake 作名詞 “錯(cuò)誤” make a mistake 出錯(cuò)e.g. you have made a mistake here. mistake…for… 錯(cuò)把……當(dāng)作…… they mistook him for his brother. by mistake 錯(cuò)誤地 e.g. they sent the letter to me by mistake. 2. geroge wanted to make the customer happy. make表示“使……怎么樣”，其后常帶復(fù)合賓語(yǔ)。常見(jiàn)結(jié)構(gòu)為：主語(yǔ)+make+賓語(yǔ)+名詞/形容詞(做賓補(bǔ)) water (產(chǎn)生) a p smell . 典型例題解析：1. did you know that tea…was invented by accident? by accident “偶然地，碰巧”。同義詞組 是by chance，同義詞是accidentally, 反義 詞組是on purpose. e.g. he found a new way to solve the problem by accident. 2. although tea wasn’t brought to the western world until 1610, …(1) although 作連詞, 意為 “雖然,盡管”,引導(dǎo)讓步狀語(yǔ)從句, 我們不能根據(jù)漢語(yǔ)習(xí)慣, 在后面使用連詞but, 不過(guò)它可以與yet, still連用;若主從句的主語(yǔ)相同, 且從句謂語(yǔ)含有動(dòng)詞be, 可將從句主語(yǔ)和動(dòng)詞be省略。e.g. although he is very busy, he always talks with us. (2) not…until 意為 “直到……才”until 引導(dǎo)一個(gè)時(shí)間狀語(yǔ)從句。 i did not go to bed until i finished my homework. 3. according to an ancient chinese legend， the emperor shen nong discovered tea…(1) according to 是個(gè)短語(yǔ)介詞,意為 “根據(jù)……;依照……”后接代詞,名詞或由疑問(wèn)詞以及whether引出的名詞性從句。e.g. according to the radio, it will rain tomorrow. (2)discover意為“發(fā)現(xiàn)”，指發(fā)現(xiàn)的對(duì)象是 本來(lái)存在的。 find意為“找到”，強(qiáng)調(diào)結(jié)果。 invent意為“發(fā)明”，發(fā)明的對(duì)象是以前沒(méi) 有的東西。3. some leaves from a nearby bush fell into the water and remained there for some time. (1) nearby adj. “附近的“，e.g. he works in a nearby factory. (2)leaf 的復(fù)數(shù)形式為leaves (3)remain 表示 “繼續(xù)留在某處” e.g. how long will you remain here? (4) fall into “落入, 陷入”e.g. he was drunk and fell into the water.
