　　⑥ at an end (1) Be patient, his speech will be at an end soon.

　　(2) The war was finally at an end.

　　根据语境，at an end意思是： ________________________________________________________________________ at an end ＝ finished结束，终止(常作表语)

　　⑥ at an end 短语 at the end of 在……尽头(末)(指时间和空间) by the end of 到……末为止(与过去完成时连用) in the end 最后，终于 at a loose end 无所事事，处于杂乱状态 make ends meet 收支相抵 come to an end结束(用作谓语) draw to an end 接近尾声 bring…to an end使……终止 put an end to 使……终止

　　⑥ at an end 用at the end of, by the end of 和 in the end填空 (1) How many English words have you learned ______ last term? (2) He became an outstanding doctor ______.

　　(3) My uncle will fly to China ______ this year.

　　(1) by the end of　(2) in the end　(3) at the end of

　　⑥ at an end

　　你知道这道题的正确答案是什么吗？为什么？ ()They walked and walked until they came ______ the end of the stream.

　　A. at

　　B. by

　　C. in

　　D. to

　　D　首先我们知道by the end of后不跟地点；in the end是一个独立使用的短语；虽然at the end of 后接地点，但它所表示的是“在……的尽头或末尾”，表示状态。而本题的语境所表示的是“来到了溪流的尽头”，所以答案是D。

　　⑥ at an end

　　⑦

　　农家大院里的鸡，甚至猪都紧张得不想吃食。 (1) too…to…太……以至不能……

　　The boy is too weak to lift the heavy box.

　　这男孩太虚弱，举不起那个重箱子。 (2)当too…to…跟少数形容词(如ready，glad，pleased，apt，willing，inclined，eager, easy, satisfied等)搭配时，不定式无否定意义。

　　He is too ready to promise. 他轻于许诺。

　　Beginners are too apt to make mistakes. 初学者极易出错。

　　⑦ too … to … (3) too…to…的否定形式not too…to…的意思是“不是太……而不能”。

　　⑦ too … to … ⑧

　　It seemed as if the world was at an end! (P26) 世界似乎到了末日！ ⑧ as if

　　当as if引导从句时，我们一定要根据语境判断语义是否符合客观实际，符合客观实际就用陈述语气，即：该用什么时态就用什么时态；不符合客观实际就用虚拟语气，即： ⑧ as if

　　as if ＋ 主语 ＋ had done sth.

　　(从句谓语动词发生在过去) did / were

　　(从句谓语动词发生在现在) would do sth.

　　(从句谓语动词发生在将来) 巧记： had done　did/ were　would do

　　之前　谓语动词　

　　之后 链接 (1)

　　as if/as though (似乎是，好像是)的功能

　　① 引导表语从句，常和动词look / seem 连用：

　　She looks as if she were ten years younger.

　　她看上去好像年轻了10岁。

　　It seems as if our team is going to win.

　　好像我们队会赢。

　　② 引导方式状语从句：

　　He treated her as if she were his daughter.

　　他对待她好像是自己的女儿。 ⑧ as if

　　(2)

　　as if (as though)可用于省略句中：as if 引导的从句常可省略主语和系动词，这样其后就只剩下名词、不定式、形容词(短语)、介词短语或分词(如文中例句)。

　　He acts as if (he were)a fool / mad.

　　他做事像个傻子 / 像疯了一样。

　　Tom raised his hands as if (he were going) to say something.

　　汤姆举起手好像要说什么。

　　⑧ as if

　　根据汉语提示完成句子 (1) There are masses of dark clouds in the sky. It seems as if it ______(将要) rain.

　　(2) He talked as if he ______(知晓) everything in the world.

　　⑧ as if

　　(1)is going to　从“天空中乌云密布”，我们就可以判断出天要下雨的可能性相当大，所以我们用陈述语气，因是客观推测的将来，所以答案是is going to。

　　(2) had known　从语境：他说起话来就好像他穷知世界一切似的。“穷知世界”这是不可能的，所以我们要使用虚拟语气。根据本句语境know的动作应发生在talk之前，所以用had known。 ⑧ as if

　　⑨ All hope was not lost. (P26)

　　并不是所有的希望都破灭了。

　　　All the students do not know how to deal with the problem.

　　＝ Not all the students know how to deal with the problem.

　　并非所有的学生都知道如何解决个问题。 ⑨ All … not …

　　1. all, both, each, every, everyone, everything, always, whole, wholly, entirely, altogether等表示“全体”意义的代词、副词或形容词与否定词not连用时，一般都表示部分否定。

　　巧记：

　　只要表示“全体”意义的词与否定词连用，都是部分否定。 ⑨ All … not …

　　2. 如果句子中出现下列词或短语则该句为全部否定：

　　none of＋n./pro.;

　　neither＋n./pro.;

　　no＋n.;

　　nothing; nobody; neither; never; nowhere;

　　neither…nor等。 ⑨ All … not …

　　翻译句子
