SAT語(yǔ)法考試選擇題解題技巧

一、改進(jìn)句子(Improving Sentences)

這部分常見(jiàn)考察點(diǎn)：

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

2.沒(méi)有用標(biāo)點(diǎn)符號(hào)來(lái)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(hào)切割句子。例如： Alex finished her homework early, after that she drove to Maria’s house.

4. 邏輯錯(cuò)誤，如該使用but連接卻使用了and。邏輯指代錯(cuò)誤等。

5. 修飾詞位置不當(dāng)

6. 結(jié)構(gòu)不對(duì)稱等。有些連接詞后要對(duì)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(cuò)誤。

還有使用and 連接兩個(gè)沒(méi)有直接關(guān)系的兩個(gè)句子。請(qǐng)看如下幾個(gè)例子：

1. Nineteenth-century nihilists were concerned with neither the origins of philosophical thought nor how societal laws developed. (x) (結(jié)構(gòu)不對(duì)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(gè)沒(méi)有直接關(guān)系的兩個(gè)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(zhuǎn)折關(guān)系，連接詞使用不當(dāng))

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(yǔ)和謂語(yǔ)，看完全句會(huì)發(fā)現(xiàn)這是個(gè)用逗號(hào)分隔的句子，顯然不符合要求。但因標(biāo)點(diǎn)處沒(méi)有劃線，所以不能改動(dòng)。根據(jù)兩句的意思可以看出應(yīng)該是轉(zhuǎn)折關(guān)系，所以B既解決了邏輯問(wèn)題，有避免了逗號(hào)切割句子的問(wèn)題。A構(gòu)成句子碎片，所以不正確。C和E沒(méi)有解決逗號(hào)分隔句子的問(wèn)題。 D邏輯關(guān)系不對(duì)。

二、改進(jìn)段落(Improving Paragraphs)

改進(jìn)段落的題型一般是一篇含有語(yǔ)法和邏輯錯(cuò)誤，多由15個(gè)到20個(gè)句子組成的文章。一般這種題型有四大類問(wèn)題：

1. 改正句子中的語(yǔ)法錯(cuò)誤，和改進(jìn)句子題的考察點(diǎn)基本一致；

2. 把兩句句子結(jié)合成一個(gè)句子；

3. 在段落中插入句子；

4. 文章分析問(wèn)題。后者多考察邏輯關(guān)系，即根據(jù)文章語(yǔ)境選擇正確的句子。

在做改進(jìn)段落題時(shí)由于文章篇幅比較長(zhǎng)，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(diǎn)閱讀，以便了解文章的大意，其它段落僅看首尾句即可。對(duì)于此類題型中的改正句子語(yǔ)法錯(cuò)誤題，在多數(shù)情況下，可以不看原文即可做出正確判斷。
