4．重读
英语的重读现象同样可以分为单词重读和句子重读。单词
重读其实就是指重音，这个可以在平时学单词时多加留意，但
也可以掌握一些规律，这样即使遇到新单词也可以根据发音规
则正确读出来。
单词重读的一般规则：实词重读，虚词不重读。
(1)名词、动词、数词、形容词、副词是实词，一般要重读。
从句子入手写好文章
文章是由句子构成的，要写好文章，首先要写好句子。句
子至少应具备下列几点才能有效地表情达意——正确、一致、
明晰、连贯、有力。然而考生受其英语基础和母语的影响，总
是会犯这样那样的错误。现将句子写作中应该注意的事项和可
能出现的错误介绍如下：
1．内容要明晰
句子表达的内容必须清楚，不能造成歧义。如：
模糊：He told his father that he was wrong.
他告诉父亲是他错了。(从句中的 he 指代不清)
清楚：He told his father that his father was wrong.
他告诉父亲是父亲错了。
清楚：He told his father that he himself was wrong.
他告诉父亲是他自己错了。
2．句子结构要对等
句子中的并列成分之间在结构上应该对等。如：
误：You may either ask your brother or your sister.
正：You may ask either your brother or your sister.
你可以问一下你的哥哥或姐姐。
3．句子要合乎逻辑
(1)句子中的名词和代词的数前后应保持一致。如：
误：Being a student, we all wish to learn English well.
正：As students, we all wish to learn English well.
作为学生，我们都希望能学好英语。
(2)句子中的语气、语态和句法结构应一致。如：
误 ： Thinking of his son, who died a week ago, tears came
down from the old man's face.
正 ： Thinking of his son, who died a week ago, the old man
burst into tears.
一想到一周前去世的儿子，老人就潸然泪下。
4．避免断句
句子结构要完整，避免写成一个短语或从句。如：
断句：How we should write.我们应该怎样写。
修订句：That is how we should write.
这就是我们应该怎样写。
修订句：How should we write？我们应该怎样写呢？
5．避免碎句
一个连贯的信息不宜用若干短句表达，改正方法主要有并
列法、从属法，也可将那些不太重要的句子缩成短语。如：
碎句：He is our English teacher.His name is Wang Bin.He has
taught us for two years.
他是我们的英语老师。他的名字叫王滨。他教了我们两年。
连 贯 ：Wang Bin, our English teacher, has taught us for two
years.王滨，我们的英语老师，已经教了我们两年。
连贯：Wang Bin has taught us English for two years.
王滨已经教了我们两年英语。
6．避免混杂句
混杂句是指句子与句子之间缺少必要的标点和连词，也指
误用连词，通常是千篇一律地使用 and, but, so 这样几个并列连
词。如：
混杂句：You enter the city and you will see the tower.
修订句：If you enter the city, you will see the tower.
如果你进了城，你就会看到那座塔。
7．避免累赘
所谓累赘是指句中使用了不必要的词。如：
累赘：The student put a letter that came from Fujian on my
desk.
简洁：The student put a letter from Fujian on my desk.
学生把一封来自福建的信放在我桌上。
与累赘相反的情况是缺词。如：
缺词：Our country is larger than any country in Asia.
完整：Our country is larger than any other country in Asia.
我们国家比亚洲其他任何国家都大。
8．避免中式英语
中式英语指句子表达不符合英语句型或英语习惯，或是书
写时只根据汉语意思选择词汇，而忽视该词在英语中的特定含
义和用法。如：
误：Tomorrow will be fine.
正：It will be fine tomorrow.明天天晴。
