A. formingB. to formC. to be formingD. have formed思路解析：promise后接不定式作宾语。and连接两个宾语，要保持它们在结构上的一致，根据to revise可判断出应该用不定式形式作宾语。答案：B黑色陷阱易误选A项。错误地认为此处应该和existing并列了。绿色通道句子中的同等成分应该在结构上保持一致，否则会使句子失去平衡和协调。这种现象称之为同等成分的一致。判断同等成分的关键是读懂句子意思，找出并列的成分是什么。【例2】 Im afraid Mr. Wood cant see you until 4 oclock. Oh, _ I wont wait. A. no doubtB. after allC. in that caseD. in this way思路解析：in that case如果那样的话。题意“恐怕伍德先生要到四点才能见你。”“唉，要是那样的话我就不等了。”no doubt 无疑地；after all 毕竟；in this way 用这种方法。答案：C黑色陷阱误选其他选项的原因是没有搞清题干意思，没有掌握词组的意义。绿色通道case 可构成许多词组：in any case 无论如何，总之；in case 如果，以防；免得；in case of 要是，万一；in no case 决不；in some cases 有时候；in the case of 至于；提到；in this/that case 既然是这/那样；假若是这/那样【例3】 Last month, part of Southeast Asia was struck by floods, from _ effects the people are still suffering. A. thatB. whoseC. thoseD. what思路解析：whose 引导定语从句，表示effects与part of Asia是所属关系。whose 即指洪水的。答案：B黑色陷阱受汉语习惯的影响，本题易错选C项。绿色通道whose引导定语从句，既可以表示“某人的”，也可以表示“某物的”，用于表示被修饰的名词与先行词是所属关系。当表示“某人的”时，可以用of whom代替whose; 表示“某物的”时，用of which 代替。【例4】 Father _ for London on business upon my arrival, so I didnt see him. A. has leftB. leftC. was leavingD. had left思路解析：根据所提供的情景“so I didnt see him”可以判断出父亲出发去伦敦发生在my arrival 之前，所以用过去完成时，表示“过去的过去”。答案：D黑色陷阱容易误选B项。看到so后面的句子用了一般过去时，所以错选了B项。绿色通道时态的选择关键是搞清楚是什么时间段，相关动作的先后。【例5】 No one helped me. I did it all _ myself. A. forB. byC. fromD. to 思路解析：by oneself表示“独自一人”。题意 “没人帮助我。一切都是我自己做的”。答案：B黑色陷阱误选其他选项是没有记清与oneself构成短语的意思。绿色通道与oneself构成的短语有：for oneself 亲自； of oneself 自动地；to oneself 独享的，自给；in oneself 本身。【例6】 _ I explained on the phone, your request will be considered at the next meeting. A. WhenB. AfterC. AsD. Since思路解析：as引导定语从句，意思是“正如”。表示正如我在电话里解释的那样。when引导时间状语从句，意思为“当的时候”。after引导时间状语从句意思为“在之后”。since引导原因状语从句，意思为“因为”。答案：C黑色陷阱误选其他选项是因为没有正确把握主从句的关系。绿色通道as 引导非限制性定语从句，代替整个主句，对其进行说明。但一般用于像as we all know, as is known to all, as it is, as is said above, as is reported in the newspaper, as mentioned above, as is usual, as is often the case等句式中。as在非限制性定语从句中作主语、表语或宾语，且引出的从句位置比较灵活，可位于句首或句末，也可插入主句中间。通常均由逗号将其与主句隔开。【例7】阅读短文，完成表格：Most hens live on farms.

Most hensLive on 1Have a 2 in a barnBabyA lucky 3, who has her own house;There are lights, a 4 , a fireplace, and a radio in her house;She can lay 5 .参考答案：1. farms2. nest3. pet hen4. doorbell5. eggs巧学园地巧记be going to 的用法be going to，表打算，准备、计划将来干。表可能，有必然，通过现象来推断。使用它，要注意，疑问形式be提前。否定句，更简单，not放在be后边。to之后，动原形，be的形式看人称。下列词，要注意，come，go和离去(leave)，进行时，表将来，牢牢记住莫忘记。客服唯一联系qq 1119139686 欢迎跟我们联系
