一、分析2019年高考英语全国卷的七选五

所谓信息词，就是能够给做题者提供一定信息的词，那么信息词主要有哪些呢？

以2019年高考英语全国卷Ⅲ为例：

1.原文再现

In an online class，developing healthy patterns of communication with professors is very important. 36While I have only listed two of each， there are obviously many other situations that can arise. Students should be able to extend the logic（逻辑）of each to their particular circumstance.

Dos

37 Questions about subject content are generally welcomed. Before asking questions about the course design， read the syllabus（教学大纲）and learning mana-gement system information to be sure the answer isnt hiding in plain sight.

Participate in discussion forums（論坛），blogs and

other open-ended forums for dialogue. 38 Be sure to stay on topic and not offer irrelevant information. Make a point， and make it safe for others to do the same.

Donts

Dont share personal information or stories.Professors are not trained nurses， financial aid experts or your best friends. If you are in need of a deadline extension， simply explain the situation to the professor. 39

Dont openly express annoyance at a professor or class.40 When a student attacks a professor on the social media， the language used actually says more about the student. If there is truly a concern about a professors professionalism or ability， be sure to use online course evaluations to calmly offer your comments.

A. what  are for.

B.urn to  online instructor for help.

C.If more information is needed，  will ask.

D.Remember that online professors get a lot of emails.

E. are some common dos and don ts for online learners.

F.Everyone has taken a not-so-great class at one time or another.

G.Ask questions，but make sure they are good，thou-ghtful questions.

2.做题技巧解答

（1）先看选项，找出信息词。（如上文所划）

在此七选五中，如学生做题之前先浏览七个选项，且把其中的信息词画出来，根据信息词判断所选的答案是否正确，则准确率就会提高了。

（2）利用选项中的信息词进行解题。

如A项中有两个信息词，一个为that，指示代词，其作用是代替前文提到的名词（如人或物）;另一个为they，人称代词，指代前面提到的复数名词（人或物均可）或不止一样东西。那么这两个词所给出的信息就是如果选了此选项，则前面必须有一个名词是that指代的内容，而同时也要有一个复数名词或名词组合是they指代的内容，否则不能选A。显然，只有38空适合选A（那就是它们的作用），其中，that指代前面的dialogue，而they指代 discussion forums， blogs and other open-ended forums这个名词组合。其次看B选项中an也属于信息词，它是不定冠词，作用是泛指第一次出现的人或物，所给的信息是如果选了此选项，则前面一般不会出现它所修饰的online instructor这个名词词组，虽然这篇文章没有要选B的空，但可利用此信息来排除。……
