GMAT考试语法知识点-总结关于“THAN”的所有帖

linly

A,主谓宾结构的比较，than后的助词需补出

一A. than后补出完全不同的名词时(这种情况下也不需要考生考虑)

The pay of senior executives increased in 1990 by a larger percentage than did the wages of other salaried workers. （原句）

The pay of senior executives increased in 1990 by a larger percentage than the wages of other salaried workers did （请注意，倒装……）

一B. than后没有补出完全不同的名词时，需不需要that/those

1.当有限制的成分时，需要that/those。

In China fewer people will enter the force than will those who live in
            USA.

In China fewer people will enter the force than those who live in USA will.

（请注意，倒装……）

这两句的第一句是错误的，若是宾语比较，则不需要加do，若是主语比较，加 助动词，倒装与否只取决于“倒装是为了避免头重脚轻”。所以，根本没有加绿线句子的情况，且(I hate him more than you do)(I hate him more than do you)两句话是同一个意思。

2.当没有限制的成分时（暂且认为时间状语“没有限制能力”），不需要that/those



As a result of the continuing decline in the birth rate, fewer people
            will enter the labor force
            in the 1980’s than
                did
            in the 1960’s and 1970’s, a twenty-year period during which people born after the war swelled the ranks of workers.

二．OG中出现的特殊情况——主谓宾结构，却没有加助动词。

A study commissioned by the Department of Agriculture showed that if calves exercise and associate with other calves, they require less medication and gain weight more quickly than those
            raised in confinement.

less medication与more quickly一个充当宾语,一个充当状语.如果都是充当宾语,则助词不可少.希望楼主能更正一下,这样大家会更明白一些. 另外,如果前面两个比较成分都是充当宾语,则助词可以省略。

linly

B,比较不涉及主谓，只比较句子的附加成分，不补助动词.



介宾比较:A do sth of C1 by D1 than of C2 by D2.（C1C2，D1D2对等名词）



一，句子结构中只有主谓，没有宾语 的情况。



因为没有宾语，只可能有主语比较，因而不需要助动词。



I eat faster than you

二A，than后没有补出完全不同的名词时

In his eagerness to find a city worthy of Priam, the German archaeologist Schliemann cut through Troy and uncovered a civilization a thousand
                        years
                        more
                        ancient
                        than
                        the
                        city known to Homer’s heroes.

linly

二B，在than后没有补出完全不同的名词时，即前后名词类同，That/those的出现“与否”仍取决于限制性修饰成分的“有无”。

1.当有限制的成分时，需要that/those。

Domestic automobile manufacturers
                        have
                        invested millions of dollars in research to

                        cars even more gasoline-efficient

                        those at present on the road.

                        higher
                        quality
                        than
                        that

                        from source twenty times fainter than those that can be detected by ground-based instruments.

2.当没有限制的成分时（暂且认为时间状语“没有限制能力”），不需要that/those

***Although Napoleon’s army entered Russia
                                with far more supplies than for any previous campaign, it had provisions for only twenty-four days.

&如果时态不一致，则需补出助词。

                        diversified than it was
                            ten years ago.

linly

C,主系表结构，不补助动词

一，than后有完全不同的名词。

Even though Bela Bartok’s music has proved less popular than Igor Stravinsky’s and less influential than Arnold Schonberg’s, it is no less important.

二，than后没有完全不同的名词时

1.当有限制的成分时，需要that/those。

Several studies have found that the coronary patients who exercise most actively are at least fifty percent less
                likely
                than
                those

who对主语进行限制，必须有that/those。

Aging is a property of all animals that reach a fixed size at maturity, and the variations in life spans among different species are
                far
                greater
                than
                those
                among individuals of the same species: a fruit fly is ancient at 40 days, a mouse at 3 years, a horse at 30, a man at 100, and some tortoises at 150.

介词对主语进行限制，所以必须有that/those。
