【正文】 l snakes. 我所做的第一件事就是看看有沒有現(xiàn)成的產(chǎn)品能幫助我。但是，看來只有一種毒殺蛇的藥粉。在there be結(jié)構(gòu)中，be的人稱與數(shù)應(yīng)遵循就近原則。There was a bucket of water and two chairs in the corner of the house.在房子的角落里有一桶水和兩把椅子。There are two chairs and a bucket of water in the corner of the house.在房子的角落里有兩把椅子和一桶水。聯(lián)想拓展there be的常見形式有：there seems to be...／there happens to be...／there used to be ...etc.高手過招根據(jù)句意在橫線上填入適當(dāng)?shù)膯卧~①The child seems (be) healthy, but the doctor is concerned. ②It seems to me there161。175。s something funny about the case.③There doesn161。175。t seem (be) much hope that he161。175。ll e. 答案： ①to be ②that ③to be 12. ...but it was not until five days later that Bell sent his first telephone message to his assistant Watson. 161。173。161。173。但是貝爾是在五天以后才跟他的助手華生通了第一次電話。該句是161。176。It is/was not until+被強(qiáng)調(diào)部分+that+其他161。177。結(jié)構(gòu)。句中用了161。176。not ...until ...161。177。的強(qiáng)調(diào)句結(jié)構(gòu)，此句型只用until，不用till。但如果不是用在強(qiáng)調(diào)句型中，till與until可通用；另外主句中的否定詞not 要提出來，放在until之前一起強(qiáng)調(diào)，因此that后面的從句要用肯定句，不能再用否定句。He didnt go to bed until/till his wife came back.=It was not until his wife came back that he went to bed. 直到他的妻子回來他才睡覺。溫馨提示not until置于句首時(shí)，要用部分倒裝句型，這時(shí)要注意從句不倒裝，只倒裝主句。Not until last week did they find the lost bike. 直到上個(gè)星期他們才找到丟失的自行車。Not until my son had entered the university did he realize the importance of time.我的兒子直到上了大學(xué)之后才意識(shí)到時(shí)間的重要性。高手過招單項(xiàng)填空①It was midnight back home after the experiment. A. until。 that he wentB. until。 that he didnt goC. not until。 that he didntD. not until。 that he went②Not until I began to work realize how much time I had wasted. didn161。175。t I B. did I C. I didn161。175。t D. I ①解析：選D。從題干和選項(xiàng)很容易看出這是一個(gè)含有not until 的強(qiáng)調(diào)句?；揪湫蜑?61。176。It is/was not until+被強(qiáng)調(diào)部分+that+其他成分161。177。，故排除A、B兩項(xiàng)。否定詞not 已提前，故主句中為肯定句，故選D。句意為：直到半夜做完實(shí)驗(yàn)后他才回來。②解析：選B。not until的倒裝句型，用部分倒裝，助動(dòng)詞提到主語之前，而且not已經(jīng)移到句首，因此句中不能再出現(xiàn)，故選B。
