It （This / That） is the first （second， third ） time + that从句（从句要用现在完成时）。这（那）是某人第一（二、三）次干某事。如主句谓语动词是过去时，则that从句要用过去完成时。5. by the time引导的时间状语从句。若从句用一般现在时，主句要用将来完成时；若从句是一般过去时，主句要用过去完成时。6. each time（每次），next time（下次）， any time（任何时候）等词组引导的时间状语从句。7. the first / second / third time 可以引导时间状语从句。14 neverseldomsometimesoften14 right adj.（形容词） 1.正当的，正直的：与正义，法律或道德相符合的或可相符合的： do the right thing and confess. 做正确的事并进行忏悔 .正确的：与事实，常理或真实情况相一致的；正确的： the right answer. 正确的回答 .合适的：适宜的，合适的，恰当的： It is not right to leave the party without saying goodbye. .顺利的，有利的：最有利的，最需要的或最方便的： the right time to act. 采取行动的最佳时间 .好的，正常的：处于令人满意的状态或情况： put things right. 把事情办好 .健康的，健全的：在神志上或身体上健康的或健全的 .正面的：需要面向外或面对观察者穿着或放置的： the right side of the dress; made sure that the right side of the fabric was visible. 右方的，右侧的，右的adv.（副词） Toward or on the right. 向右，右边 In a straight line; directly: 直接地：以直线地；直接地： went right to school. 直接去学校 In the proper or desired manner; well: 好：以正确的或需要的态度地；好地： The jacket doesnt fit right.

(2) spend time money (in) doing sth. 花费时间（金钱）做某事。They spent two years (in) building this bridge. cost的主语是物或某种活动， 还可以表示“值”， 常见用法如下：(1)sth. costs (sb.) 金钱,某物花了（某人）多少钱。例：A new computer costs a lot of money.

Ill pay it back next week. （6） （6）pay off ones money还清钱。16 no longer=not any longer, no more=not any more no more 和 not any more 可以做宾语，no longer 不可以 No longer意思是“不再”，其确切含意为某状态在某个时刻之后不再继续下去了。有两个短语和no longer同义，即notany longer和notany more，但他们侧重的方面不同。前者侧重时间，比如： He no longer lives here. = He doesnt live here any longer. You can drink no more. = You cant drink any more. 要注意的是：由于no longer本身就带有否定的含义，即表示“再也不”，所以不能在同一个句子中加入否定词，比如： Ill come here no longer. 17 chat with sb= have a chat with sb18 bring/ take/carry/fetch(1) bring一般是指拿来，即从别处往说话人这里拿，翻译成“带来”。Please dont forget to bring your homework tomorrow.(2) take一般是指从说话人这里往别处拿，翻译成“带走”。Please take the umbrella with you.

Hardly did I believe what you said. 句子中有 hardly 时,其反意疑问句的疑问部分应该 用肯定形式. He can hardly understang it ,can he ? hardly ever其实是表示一种否定的频度，相当于rarely, seldom, almost never等。My mother lives so far away that we hardly ever see her.在hardlywhen before（一就）这一句式中，原则不能用hardly ever，因为这里的hardly并不表频率。如：I had hardly closed my eyes when the telephone rang.20 miss v. 想念，错过，未察觉 I miss you very much. I missed the most exciting part of the film. missing: lostmissing通常看作是现在分词变过来的形容词，意思是”失踪的，不见的“，和lost意思和词性相接近，My wallet is missing.21.in the last few years = in the past few years 与现在完成时连用22. make的用法 make +sb +adj. 使得某人 make sb+ do sth 使得某人做某事 make sb/sth + doing 使某人一直做某事 make sb + n. 使某人成为 make sb/sth +done 使某人/某事被 The bad news made me sad.
