在SAT考試當(dāng)中，很多同學(xué)都會遇到很多關(guān)于考試的內(nèi)容，特別是想閱讀和文法的題目，讓很多同學(xué)在備考SAT的過程當(dāng)中非常的苦惱，今天我們給大家分享一下SAT考試當(dāng)中文法部分的一些知識，包含了一些解答方式，大家可以了解一下哦。

平行結(jié)構(gòu)含義：兩個(gè)或兩個(gè)以上句法、功能相同的詞，詞組或句子，通過并列連詞、并列詞組連接起來而構(gòu)成，共同承擔(dān)句子的某一成分的結(jié)構(gòu)叫做平行結(jié)構(gòu)。

2.類型：

(1) 比較平行

1)  A than B

2) (not) as A as B

3) (not) so A as B

4) (not) such much as A as B

3. 用法

（1）比較對象前后的形式和功能完全一致。

例如1

It is far easier to ride a bicycle than to explain in words exactly how a bicycle is ridden.

解析：than之前是to ride，根據(jù)前后一致的原則，than后面應(yīng)該也是to do的形式，所以用to explain。

（2）對于前面出現(xiàn)的不可數(shù)名詞或單數(shù)名詞，用that代替；可數(shù)名詞用those代替。

例如1

The title of this book is more interesting than that of that book.

解析：比較的是這本書與那本書的title，是單數(shù)名詞，所以用that代替。

例如 2

The contents of this book are more interesting than those of that book.

解析：比較的這本書與那本書的contents，是復(fù)數(shù)名詞，所以用those代替。

題目檢測
題目檢測 1

At that time, chopsticks—which were then called “Zhu”— were used for cooking rather than to eat.

A. NO CHANGE

B. The purpose of eating

C. when one ate

D. eating

解析：通過題中的than看出是比較平行的考點(diǎn)，根據(jù)“比較對象形式和功能完全一致”的原則，than前面是cooking，所以than后面需要是動名詞的形式，A的to eat、B的the purpose和C項(xiàng)when從句都與之前不一致，所以排除A、B和C項(xiàng)，所以選D。

題目檢測 2

It was said that Mary could classify three group of ants a minute and, using a magnifying glass, could classify group of ants down to the 9th magnitude-sixteen times fainter than humans.

A. NO CHANGE

B. the human eye.

C. that of the human eye

D. what can be seen by the human eye.

解析：通過題中的than看出是比較平行的考點(diǎn)，題目說瑪麗用放大鏡識別不同族群的螞蟻，根據(jù)“比較對象形式和功能完全一致”的原則，than前面使用一種方式識別螞蟻，所以than之后也需要另一種方式，而無論是humans, the human eye還是that of the human eye都不能表達(dá)到位，所以排除A/B/C選項(xiàng)，所以選D。

題目檢測 3

The equipment of this building, which has been 400 years old, is so much complicated as that building.

A. NO CHANGE

B. as one building.

C. as that of that building.

D. as this building.

解析：通過題中的than看出是比較平行的考點(diǎn)，題目比較的是這個(gè)大樓的設(shè)備和那個(gè)大樓的設(shè)備，根據(jù)“不可數(shù)名詞或單數(shù)名詞，用that代替”的原則，than后面應(yīng)該用that替換，而A項(xiàng)的that building對應(yīng)than之前的this building，所以需要另外一個(gè)that代替equipment，而無論是that building, one building還是this building都不能表達(dá)到位，所以排除A/B/D選項(xiàng)，所以選C。
