五、句子的結(jié)構(gòu)來源：考試大
句子的結(jié)構(gòu)主要考查四個(gè)出題方向。
(一) 主語的重復(fù)來源：考試大
名詞+代詞+謂語，這個(gè)代詞永遠(yuǎn)是重復(fù)的主語，永遠(yuǎn)是錯(cuò)的
例：Woodrow Wilson he was an idealist who refused to make any
A B
compromises concerning the establishment of the
C D
League of Nations.
分析：代詞he不是同位語，主語重復(fù)；如果是下面這樣的主語，那么便是主語同位語
A prolific writer, Woodrow Wilson
例：Two unique features of the Arctic they are
A B
lack of precipitation and permanently frozen ground.
C D
分析：選項(xiàng)B中的they和前面的主語two unique features重復(fù)
(二)謂語的重復(fù)來源：考試大
完整的句子后面又多了一個(gè)謂語，往往改為定語從句
例：A paragraph is a portion of a text consists of 來源：考試大
A B
one or more sentences related to the same idea.
C D
分析：B錯(cuò)，應(yīng)改為consisting of或which consists of。句中有兩個(gè)無法連接的謂語動(dòng)詞，而且前一個(gè)謂語動(dòng)詞下面沒有劃線，故改consists為非謂語動(dòng)詞形式或在它前面加which使之成為從句謂語動(dòng)詞。
(三)謂語的缺少來源：考試大
例：Most mammals to maintain a relatively constant body
A B
temperature, regardless of what the air temperature might be.
C D
分析：A錯(cuò)，應(yīng)改為maintain。句中缺謂語動(dòng)詞，故去掉不定式符號(hào)to 使maintain變成謂語動(dòng)詞。
(四)主句的重復(fù)
主句的重復(fù)總是考even, instead, during, despite等引導(dǎo)的句子, 但是實(shí)際上它們無法把兩個(gè)句子連接起來，因?yàn)樗鼈兌际歉痹~或者介詞，連接兩個(gè)句子應(yīng)該用連接詞連接
例：Salmon spend most of their adult lives in salt water, despite
A B C
they return to their freshwater birthplaces to spawn and die.
D
分析：C錯(cuò)，應(yīng)改為though。despite是介詞，后面一般接名詞作賓語，而在句中它后面卻跟著一個(gè)完整的句子，所以改為連詞though。
例：Solar eclipses occur during the Moon's shadow 來源：考試大
A B
sweeps across the face of the Earth.
C D
分析：B錯(cuò)，應(yīng)改為when或as。介詞不能引導(dǎo)條件狀語從句，根據(jù)題意改為從屬連詞when或as。
例：Even many early leaders of the United States have provided
A B
names for towns, only George Washington來源：考試大
C
is remembered in the name of a state.來源：考試大
D
分析：A錯(cuò)，應(yīng)改為Even though。even為副詞，不能引導(dǎo)從句，根據(jù)題意，改為引導(dǎo)讓步狀語從句的Even though。
