13.此狗主人740 语法只记得一个了， 是考 as much and more than 那个东西的，但是选项里没有at least as much as, 有的那几个都挺奇怪的，还有一个选项有破折号~

＊破折号的用法前面总结过咯，详见第6个语法狗 总结知识点：比较 坦白讲我没有看明白狗主人的as much and more than，但是先把比较拿出来帮大家回忆一下吧，反正比较的考点经常出现。 究竟什么东西在比较？？ 借助og上第18题 Plants are more efficient at acquiring carbon than are fungi,
in the form of carbon dioxide, and converting it to energy-rich sugars. (A) Plants are more efficient at acquiring carbon than are fungi,
不符合后面要修饰的东西 (B) Plants are more efficient at acquiring carbon than fungi,
同上＋than前后比较对象变成acquiring carbon vs fungi (C) Plants are more efficient than fungi at acquiring carbon, (D) Plants, more efficient than fungi at acquiring carbon,
缺少v (E) Plants acquire carbon more efficiently than fungi, 同B than前后比较对象变成acquire carbon vs acquire fungi （仔细体会） 正确答案C 这里给大家放个大知识点，也是从CD上摘录的，总结比较详细，就是有点多，大家选择着看。 比较总结 总结一下关于比较的结构考点 对主谓宾全的句型 主语比较：
A do sth
than B do.（AB为对等名词，加do是为了显示这是一个可以发出动作的名词，因而确定是主语，进而确定是主语对比） 介宾比较 A do sth of C1 by D1 than of C2 by D2.（C1C2，D1D2对等名词） 宾语比较 A do C1 than C2.(C1C2为对等名词） 状语比较A do sth than usual/everbefore/people expected(直接加状语） 按照这个原理，对下一种句型只有主谓，没有宾语的句子，因为没有宾语，只可能有主语比较，因而不需要重复do来确认这是一个可发出动作的主语，所以其比较形式如下： I eat faster than you.注意与下句区别 I eat apple faster than you do 如果写成 I eat apple faster than you 按ETS的理解，从语法上就变成我吃苹果比吃你快，成了宾语比较。逻辑上显然不通。 补充NN总结的more/ less/ adj+er than语法点： （1）主语比较 1.1
than前若有宾语，则其后的助词需补出，时态要据后定。主语相同可省 eg：The pay of senior executives increased in 1990 by a larger percentage than did the wages of other salaried workers. eg：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. (主语people相同且无定语成分则省之，但did不能省) eg：Several studies have found that the coronary patients who exercise most actively are at least fifty percent less likely than those who are sedentary to die of a heart attack.（主语相同且有定语成分，必须要that/those来指代） 1.2
than前只有BE + ADJ，则其后的主语无须补助词。 eg：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. eg：In 1982 the median income for married-couple families with a wage-earning wife was $9,000 more than that for families in which only the husband was employed. 1.3 than前有两个动词，比较主语无须补助词。 eg：A study commissioned by the Department of Agriculture showed that if calves exercise and associate with other calves, they have require less medication and gain weight more quickly than those raised in confinement. （2）than后名词前的介词要补出 eg： 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. 介宾的比较。 eg：The investor who is uncertain about the future is more likely to put money into blue-chip stocks or treasury bills than into gold. eg：Nowhere in Prakta is the influence of modern European architecture more apparent than in its government buildings.（倒装句） （3）宾语比较，一般加that/those eg：In addition to having more protein than wheat does, rice has protein of higher quality than that in wheat, with more of the amino acids essential to the human diet. (B-p106-19) （4）宾语补语，比较结构修饰宾语，无须补出助词； eg：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. （5）likely引导的表语比较 eg：St. John’s , Newfoundland, lies on the same latitude as Paris, France, but in spring St. John’s residents are less likely to be sitting at outdoor cafes than to be bracing themselves against arctic chills, shovelling snow, or seeking shelter from a raging northeast storm. （6）宾语+介词混合结构： eg：Although Napoleon’s army entered Russia with far more supplies than for any previous campaign, it had provisions for only twenty-four days. （7）句子的比较 eg：In Japan elderly people are treated with far greater respect than they are in most Western countries. eg：Dr. Hakuta’s research among Hispanic children in the United States indicates that the more the children use both Spanish and English, the greater their intellectual advantage in skills underlying reading ability and nonverbal logic. (B-p106-7) （8） than ever, than anticipated/ estimated… eg：The report on the gross national product—the nation’s total production of goods and services—showed that second-quarter inflation was somewhat lower than previously estimated and that the savings rate was slightly higher. （9） more than, less than 及其他。 视同副词 eg：Founded in 1983, the magazine has since more than doubled its circulation and its advertising. 视同形容词 eg: No less an authority than Walter Cronkite has reported that half of all Americans never read a book.
(10) 插入语 eg: The visiting pharmacologists concluded that the present amalgam of Chinese and Western medicine is probably as good as, or better than, any other system that might be devised for the patients treated at the Nan Kai hospital in Tian-jing. |
