分享ACT语法常见错误及例题

　　英语并非是我们的母语，所以想要提升ACT语法是相当有难度的，学好语法的关键就是及时纠正学习中的错误，为了帮助大家更好的复习ACT语法，下面小编就为大家分享ACT语法常见错误及例题！

　　1. 要素完整

　　出题形式：

　　主语和谓语被修饰成分隔开，主语和修饰成分划线

　　定语从句中主语和谓语被修饰成分隔开，定从主语和修饰成分划线

　　两个并列谓语必须要用连词连接

　　解题思路：

　　一定要找出划线部分句子的所有谓语。如果主语和谓语之间被修饰成分隔开，修饰成分前后必须保持一致。

　　例题：

　　1）Company, wantingto boost its sales of bacon, hired a reputable expert in public relations named Edward Bernays.

　　NO CHANGE

　　Company wanting

　　Company wanted

　　Company wants

　　解题思路：第一步，先找出主语和谓语。主语是 “company”, 谓语是 “hired”. 第二步，发现主语和谓语被修饰成分隔开，那么修饰成分“wanting to boost its sales of bacon” 前后标点必须保持一致。因为题中修饰成分后用逗号隔开，所以修饰成分前也必须有逗号。所以直接选A

　　2）Without the tree, the front yard changed. Somecacti, whichI’d never givenmuch attention to went wild, blossoming in crimson flowers.

　　A. NO CHANGE

　　B. cacti, that

　　C. cacti,

　　D. cacti

　　解题思路：第一步，找出划线部分句子的主语和谓语。主语是 “some cacti”, 谓语是 “went”. 第二步，发现主语和谓语被修饰成分隔开，那么修饰成分前后标点必须保持一致。因为题中修饰成分后没有用逗号隔开，所以修饰成分前也不用逗号隔开。最后只有D满足条件。

　　3）Bernays gained fame from his application of psychology to businessstrategy;after being hired by varied groups and corporations, became known as “thefather of public relations.”

　　A. NO CHANGE

　　B. strategy and,

　　C. strategy; and

　　D. strategy,

　　解题思路：第一步，找出划线部分句子的主语和谓语。主语是 “Bernays”, 谓语是 “gained” 和 “became”。因为两个并列谓语必须要用连词连接，V1 and V2. 所以最后只能选B。B选项中 “and” 和 “became” 之间插入了修饰成分，前后都要用逗号隔开。这道题错误率非常高，所以大家切记找谓语时一定要把题中所有的谓语动词都找出来。

　　4）One of the liveliestfolk music forms to develop in the twentieth century is Tejano music.

　　A. NO CHANGE

　　B. One of the most liveliest

　　C. The most lively

　　D. The liveliest

　　解题思路：第一步，找出主语和谓语。主语是 “One of the liveliest folk music forms”, 谓语是 “is”. 第二步，发现主语和谓语被修饰成分隔开，修饰成分前后标点保持一致。所以直接选A。这道题很多人错的原因是把 “forms” 误认为谓语动词。如何避免这种错误呢？一定要把句中所有的谓语动词都找出来。发现两个谓语动词没有用连词连接，肯定只能有一个谓语动词了。

　　5)The morning sunshinesthrough wind-whipped branches create an odd effect in the artist’s studio.

　　NO CHANGE

　　shone

　　shining

　　shined

　　解题思路：这道题和上一题是同一种出题形式。很多人误选A的原因都是没有找到句中真正的谓语动词 “create”。一旦找到谓语动词 “create”，那主谓之间的成分只能是修饰成分，所以只能选C

　　6）Banneker’s grandmother was an indentured servant from Englandwhom,aftercompleting the term of her contract, bought some land and then married a freedslave.

　　A. NO CHANGE

　　B. who,

　　C. which,

　　D. OMIT the underlined portion.

　　解题思路：定语从句里面的主语和谓语被修饰成分隔开，修饰成分前后标点也必须保持一致。所以直接选B。

　　2. 句子连接

　　出题形式：

　　S1,S2两句话之间划线

　　S1, 修饰成分, S2  划线部分在S1最后和修饰成分之间

　　解题思路：

　　两句话只能用连词或者分号，冒号，破折号连接

　　例题：

　　1）This knowledge reassures and inspiresme. WhenI remember that human beingsshare many of he same hopes, and fears, dreams and disappointments, then Ican help my relationship.

　　A. NO CHANGE

　　B. myself when

　　C. me, when

　　D. me when

　　解题思路：看到两句话之间划线，马上联想句子连接这个考点。前面是一个简单句。后面是“when”连接的一个主从句。两句话用句号连接，所以正确，直接选A。很多人误选其他选项是把副词“then”误认为连词。“thus, therefore, thereafter, however, nonetheless, then, also, meanwhile” 这些词都是常考的副词，不能连接两个句子。

　　2）A horse-in-motion provides steady sensory input to the patient,and thenthewalking speed of the horse can be controlled, so can the level of sensory input.

　　A. NO CHANGE

　　B. this means

　　C. and because

　　D. DELETE the underlined portion.

　　解题思路：看到连句话之间划线，马上联想句子连接这个考点。一共有三个句子，第三个句子是一个难点。第三句中的 “so” 并不是连词，而是代词。是一个倒装句。所以三个句子需要有两个连词连接，只能选C。“and” 连接S1和S2. “because” 连接S2和S3.

　　3）In the 1960s, she moved into the White House with her husband, PresidentLyndonJohnson, bythen widely known as “Lady Bird” Johnson, this crusadertook a stand for native plants and the wildlife that depend on them.

　　A. NO CHANGE

　　B. Johnson. By

　　C. Johnson by

　　D. Johnson by，

　　4）A forest crowded in on all sides as if trying to smother thecastle, likea dragon’s tongue, a red flag snapped in the March wind.

　　NO CHANGE

　　castle. Like

　　castle like

　　castle,

　　解题思路：第三题和第四题出题形式完全一样。都是在第一句话最后和修饰成分之间划线。马上联想句子连接考点。一般都是直接把修饰成分前面逗号改成句号，修饰成分大写。ACT常出现的修饰成分包括 doing, done, 介词短语。这种题每次考试都会出现，本书并不难，难在很多同学并不能马上识别句子连接这个考点。

　　3. however

　　出题形式：

　　S1. However, S2

　　S, however, VO

　　解题思路：

　　however是副词，可以作插入语，通常插在一句话主语和谓语之间。前后用逗号隔开。

　　一定不能连接两个句子，所以如果在两句话之间，必须将“however”前面的逗号改成句号。

　　1）In college, she explored and refined thisfascination, however,her personal life would not sit still for her art.

　　NO CHANGE

　　fascination, however

　　fascination however

　　fascination; however,

　　解题思路：划线部分在两句话之间，马上联想句子连接考点。however是副词，不能连接两句话，所以直接选一个能够连接两句话的选项，最后选D

　　2）He foundout, however,that the public preferred live magic acts to filmed version.

　　NO CHANGE

　　out, however;

　　out, however

　　out however,

　　解题思路：“however” 在谓语和宾语从句之间作插入语，所以前后要用逗号隔开。直接选A

　　4. must do VS must have done

　　出题形式：

　　must后面划线

　　解题思路：

　　must do: 意思是必须

　　must have done: 表示推断，意思是一定

　　需要根据句意选择

　　例题

　　History stays alive in the telling, as previous keepers mustunderstandeachtime they looked at the pictures on their winter count and started to speak.

　　A. NO CHANGE

　　B. have understood

　　C. had understood

　　D. understood

　　解题思路：在句中表示的是意思是一定理解，而不是必须理解，所以直接选B
