句子补充专项训练

修改病句句子专项训练的方法有检查句子结构是否完整，是否符合语法规则、保持原意不变，不要改变句子的主题和核心意思、修改病句需要综合考虑语法、逻辑和表达方式等多个方面，其相关内容如下：

1、检查句子结构是否完整，是否符合语法规则：检查句子中的词语搭配是否恰当，是否有歧义；检查句子中的逻辑关系是否清晰，是否存在矛盾或错误；检查句子的表达方式是否准确、简洁、通顺。

2、保持原意不变，不要改变句子的主题和核心意思：使用简洁明了的语言，避免冗长复杂的句子结构；注意词语的准确性和恰当性，避免使用模糊或不恰当的词语；注意句子的连贯性和流畅性，避免出现断句或突兀的表达方式。

3、修改病句需要综合考虑语法、逻辑和表达方式等多个方面：通过细致的分析和修正，使句子更加准确、清晰、通顺。原理是通过对句子的语法、逻辑和表达方式进行分析，找出其中的错误或不合理之处，并进行修正。

病句的相关信息

1、主谓不一致、词序不当：主语和谓语在人称、数等方面不一致，如“他们都喜欢音乐”中的“他们”应改为“他们中的每个人”。词语的顺序不符合语法规则，造成句子不通顺，如“他喜欢跑步和游泳”中的“和游泳”应改为“游泳和跑步”。

2、搭配不当、成分残缺或赘余：词语之间的搭配不符合习惯用法，如“我喜欢吃水果沙拉”中的“吃”应改为“喝”。句子缺少必要的成分或者有多余的成分，如“他昨天去了北京，参观了故宫。”中的“了”应去掉。

3、结构混乱、表意不明：句子的结构不清晰，难以理解，如“因为我喜欢所以买了这本书。”中的因果关系不明确。句子的意思不清楚，容易产生歧义，如“他告诉我一个好消息。”中的“一个”可以修饰“好消息”，也可以修饰“他告诉我”。

A. that B. when C. where D. why

考点考查表语从句。

2.（2011山东卷 33﹚We’ve offered her the job, but I don’t know______ she’ll accept it.

A. where B. what . whether D. which

考点此题考查宾语从句的引导词。

3.（2011上海卷 35﹚There is clear evidence _____ the most difficult feeling of all to interpret is bodily pain.

A. what B. if C. how D. that

考点考查名词性从句中的同位语从句。

7.（2011江苏卷 26﹚It was never clear _______ the man hadn’t reported the accident sooner.

A. that B. how C. when D. why

考点考查主语从句。

解析句意：这名男子没有早点报告这次事故的原因根本没有搞清楚。It在句中是形式主语，真正的主语是why引导的主语从句。

8.（2011辽宁卷 23﹚Twenty students want to attend the class that aims to teach ______ to read first.

A. what B. who . how D. why

考点考查名词性从句。

解析句子意思：20个学生想要去听旨在教授如何快速阅读的课程。根据句子结构可知，that aims to teach ______ to read first.是定语从句，修饰先行词class，在此定语从句中，teach后接的宾语从句中缺少表示方式的连接词，故how正确。此处为“连接词+to do”结构。

9.（2011辽宁卷 32﹚When the news came _____ the war broke out, he decided, to serve in the army.

A. since B. which C. that D. because

考点考查同位语从句。

12.（2011重庆卷 22﹚It is still under discussion __________the old bus station should be replaced with a modern hotel or not.

A. whether B. when C. which D. where

考点考查名词性从句。

14.（2011湖南卷)31﹚Before a problem can be solved, it must be obvious ______the problem itself is.

A. what B. that C. which D. why

考点本题考察的是名词性从句中主语从句。

17.（2010天津﹚As a new graduate, he doesn’t know it takes to start a business here.

A. how B. what C. When D. which

考点考查名词性从句。

解析句意：作为一名新毕业生, 他不知道需要什么才能在这里开始经营。空格后的从句中takes是动词, 其后缺少宾语, 所以引导该宾语从句的连接词要用what。

18.（2010北京﹚ some people regard as a drawback is seen as a plus by many others.

A. Whether B. What C. That D. How

考点本题考查主语从句。

解析句意：一些人眼中的缺点是别人眼中的优点。从句中缺宾语, 只能用B. what来引导. C.中的That引导主语从句不做成分。

19.（2010浙江﹚—How about camping this weekend, just for a change?

20.（2010浙江﹚It is uncertain side effect the medicine will bring about, although about two thousand patients he taken it.

A. that B. what C. how D. whether

考点本题考查主语从句的引导词。

解析根据句意：尽管大约有两千名病人服用过这种药物, 但是, 它会带来什么样的副作用还不确定。side effect意思是 “副作用”, 还原主语从句中的主干是the medicine will bring about ______ side effect。故选择what, 形容词 “什么样的”, 起修饰作用。

21.（2010上海﹚One reason for her preference for city life is she can he easy access to places like shops and restaurants.

A. that B. how C. what D. why

考点此处考查的是同位语从句。

22.（2010湖北﹚The news ________（房价将要下跌）has caused many people to sell their houses at lower prices. (fall)

答案that the housing price will fall

23.（2010山东﹚Before the sales start, I make a list of ______ my kids will need for the coming season.

A. why B. what C. how D. which

考点本题考查宾语从句的引导词。

解析句意应为 “在大甩卖开始前, 我把孩子们在下个季节里要用到的东西列了一个清单。”分析句式结构可知, 空格处在句中引导宾语从句且在从句中充当need的宾语, 所以B项结构正确。which 引导名词性从句时多表示疑问且要有一个明确的范围。

24.（2010上海﹚When changing lanes, a driver should use his turning signal to let other drivers know .

　A. he is entering which lane B. which lane he is entering

　C. is he entering which lane D. which lane is he entering

25.（2010四川﹚How much one enjoys himself trelling depends largely on he goes with, whether his friends or relatives. w_

A. what B. who C. how D. why

考点考查介词后的宾语从句。

26.（2010全国Ⅰ﹚We hen’t discussed yet ______ we are going to place our new furniture.

　A. that B. which C. what D. where

考点根据选项此题考查从句。题

解析句意：我们还没有讨论把我们的新家具放在哪里。干中空格划在动词discuss的后面, 因此考查宾语从句, 根据句意在宾语从句中缺少地点状语, 因此选择D。

27.（2010湖北﹚I want to be liked and loved for I am inside.

A. who B. where C. what D. how

考点宾语从句

解析我想别人喜欢我是因为我的内在。也就是我inside的品质。只有what可以指代是什么。很多同学误选A, 错误的用中文语言习惯去做英文题。

28.（2010全国Ⅱ﹚—He you finished the book?

---No,I’ve read up to_________the children discover the secret ce.

A.which B.what C.hat D.where

考点考查宾语从句。

解析Up to为介词结构, 后接宾语从句从句；而句意是 “读到孩子们发现秘密洞穴的地方”, 故用where引导这个宾语从句最合适。

29.（2010江苏﹚—I prefer shutting myself in and listening to music all day on Sundays.

—That’s_______I don’t agree. You should he a more active life.

A.where B.how C.when D.what

A. what B. that C. why D. whether

考点本题考查表语从句。

三年级修改病句专项训练题有用词不当、前后矛盾、重复累赘、成分残缺、语序不当等。

1、题目：用词不当。例句：我正在聚精会神地看**。解释：这个句子的用词不当。应该用全神贯注来替换聚精会神，因为全神贯注更准确地描述了看**时的专注状态。

2、题目：前后矛盾。例句：我非常喜欢踢足球，一有时间就去踢球。解释：这个句子前后矛盾。前面说非常喜欢踢足球，但后面说一有时间就去踢球，时间上存在矛盾。可以改为我非常喜欢踢足球，一有时间就会去踢球。

3、题目：重复累赘。例句：我非常喜欢唱歌，每天早上都唱一次歌。解释：这个句子重复累赘。每天早上都唱一次歌，可以改为每天早上都唱歌。

4、题目：成分残缺。例句：今天我们全家去公园玩，我很高兴。解释：这个句子缺少主语。可以改为：今天我们全家去公园玩，我很高兴。

5、题目：语序不当。例句：我最喜欢的水果是苹果、香蕉和橙子。解释：这个句子的语序不当。可以改为：我最喜欢的水果是苹果、橙子和香蕉。

修改病句的技巧：

1、读懂原句意思：在修改病句之前，要先读两遍原句，了解句子的原意。如果读不懂句子的意思，就难以判断出哪里有问题。

2、找准病因：在理解原句意思之后，要仔细分析句子中存在的病因。常见的病因包括用词不当、前后矛盾、重复累赘、成分残缺和语序不当等。

3、对症下药：根据找出的病因，取相应的修改方法。如果是用词不当，可以替换掉不合适的词语；如果是前后矛盾，可以调整句子的逻辑顺序；如果是重复累赘，可以删去多余的词语；如果是成分残缺，可以补充完整缺少的成分；如果是语序不当，可以调整句子的语序。

4、仔细检查：修改完病句之后，要再读一遍句子，检查修改后的句子是否通顺、合理，是否符合原意。如果发现问题，要及时进行修改。

5、多练习：修改病句需要多加练习。可以找一些病句练习题来做，通过反复练习，逐渐掌握修改病句的方法和技巧。
