介词的搭配是SAT语法答题原则中最重要的一项,也是大家在备考中一定要准备的。下面天道小编就从介词搭配原则中最常见的几条说起,为大家总结了相关的内容,希望这些能够帮助正在备考的考生们。
(1) 代词一定有它要指代的先行词,找不到先行词的说明代词用法错误
(2) 代词与先行词的数量上必须一致,例如:前面为boys 后面用they而非he
(3) 代词指代必须符合逻辑,例如:The term “computer killer” may sound exaggerated, but it indeed paralyzed many computers.
此处it 指代term,term使得电脑瘫痪,显然逻辑意思不正确。
(4) 代词指代不能同时指代两个不同意义的词语,否则为指代歧义
(5) 做主语的代词,优先指代主语
例如:Because it was robbed last month, the door to the house is locked.
此处it 在从句中做主语,此处它优先指代the door,把the door带入从句后,发现逻辑出现错误,因此指代错误,这个句子错误。
下面天道专家为大家总结的是经过考生反复实践之后得出的一些经典的结论,供大家参考。
1、one’s doing结构,如果不是想要表达它的动名词结构用法,则一般为错误的
例如:(1)After several years of rapid growth, the health care company became one of the largest health care providers in the metropolitan area, but proved unable to handle the increase in business, falling months behind in its paying to doctors and hospitals.
分析:后面 in its paying中,paying 想要做的是动词:pay to doctors and hospitals,在its paying中paying成为了动名词,是没有必要的,属于不简洁;另外the health care company 是这句话的主语,句子已经很清晰地表述了是the health company fell behind in paying to doctors and hospitals,所以不需要用its来进行强调“是谁fell behind in paying to doctors and hospitals”
因此 its 在此处是多余的
(2)By sucking sap from the young twigs of the hemlock tree, the woolly adelgid retards tree growth, causing the color of needles to change from deep green to grayish green, and the their dropping.
分析:their dropping中,dropping成为了动名词,使得句子成为cause the color of needles...........and their dropping. 显然使得句子的意思改变,原句想要表达的是cause the color of needles....and to drop。并且,color 和 dropping不平行。
2、同一句话中相同的代词优先指代相同的事物
例如:As a baby emerges from the darkness of the womb with a rudimentary sense of vision, it is legally blind if it were an adult with such vision, because it would be rated about 20/500.
分析:出现两个it,第一个it显然在指代a baby,根据同一句话中相同的代词优先指代相同的事物,第二个it也在指代baby,带入语义后逻辑意思错误,不是baby would be rated about 20/500,而是视力。因此此处it使用错误
3、代词不优先指代出现在前面介词短语或插入语中的名词
例如:Unlike more established industries, with clearly defined lines of competition, those of the Internet industry are blurred and indistinct, as competing companies one day maybe partners the next.
分析:those此处根据语义想要指代的是lines of competition,但此处lines of competition在两个逗号之间,视为插入语,为了方便考生,是可以删除理解的,因此不能成为被指代的内容。
所以大家在备考SAT语法中介词搭配原则的时候,一定要以最真实的SAT语法真题为基准,这样才能更加的有条理也能更加的准确。在这个过程中大家就会在掌握知识点的同时对相关的出题方法也有详细的掌握了。
