SAT語法考試選擇題解題技巧

一、改進句子(Improving Sentences)

這部分常見考察點：

1.支離破碎的句子。 例如： Although he studies hard.

2.沒有用標點符號來分割句子。例如：In the past I worked at a language school in New Zealand now I am back in China.

3. 使用不正確的逗號切割句子。例如： Alex finished her homework early, after that she drove to Maria’s house.

4. 邏輯錯誤，如該使用but連接卻使用了and。邏輯指代錯誤等。

5. 修飾詞位置不當

6. 結構不對稱等。有些連接詞后要對稱，如： neither…nor…, either… or…, both… and…, the more… the more…, not only… but also… 特別是but also 部分經(jīng)常容易有錯誤。

還有使用and 連接兩個沒有直接關系的兩個句子。請看如下幾個例子：

1. Nineteenth-century nihilists were concerned with neither the origins of philosophical thought nor how societal laws developed. (x) (結構不對稱)

Nineteenth-century nihilists were concerned with neither the origins of philosophical thought nor the development of societal laws. (√)

2. The junior class built a homecoming float, and it had lights and a sound system that worked amazingly well. (x) (使用and 連接兩個沒有直接關系的兩個句子)

The junior class built a homecoming float. It had lights and a sound system that worked amazingly well. (√)

3. Ben Franklin was a respected and talented statesman, and he was most famous for his discovery of electricity. (x) (轉折關系，連接詞使用不當)

Ben Franklin was a respected and talented statesman, but he was most famous for his discovery of electricity. (√)

例題分析：

Credulous people believe in the existence of extra-terrestrial beings, most scientists and other informed students of nature do not。

A. Credulous people believing

B. While credulous people believe

C. Credulous people are always believing

D. Since credulous people believe

E. Credulous people tend to believe

解析：本句的主語和謂語，看完全句會發(fā)現(xiàn)這是個用逗號分隔的句子，顯然不符合要求。但因標點處沒有劃線，所以不能改動。根據(jù)兩句的意思可以看出應該是轉折關系，所以B既解決了邏輯問題，有避免了逗號切割句子的問題。A構成句子碎片，所以不正確。C和E沒有解決逗號分隔句子的問題。 D邏輯關系不對。

二、改進段落(Improving Paragraphs)

改進段落的題型一般是一篇含有語法和邏輯錯誤，多由15個到20個句子組成的文章。一般這種題型有四大類問題：

1. 改正句子中的語法錯誤，和改進句子題的考察點基本一致；

2. 把兩句句子結合成一個句子；

3. 在段落中插入句子；

4. 文章分析問題。后者多考察邏輯關系，即根據(jù)文章語境選擇正確的句子。

在做改進段落題時由于文章篇幅比較長，因此很多情況下，不需要通篇閱讀。一般可以開始的段落重點閱讀，以便了解文章的大意，其它段落僅看首尾句即可。對于此類題型中的改正句子語法錯誤題，在多數(shù)情況下，可以不看原文即可做出正確判斷。
