改错三练
答题步骤:
1、一般来说,做题时千万不要拿起来就改。先花一、两分钟从头到尾通读全文,对文章大致内容有所了解,做到心中有数。
2、然后把重点放在有错误项的标题号行,寻找较容易辩认的语法错误,如主谓不一致、时态、语态使用错误、非谓语动词错误等等。
3、如果错行中不存在上述明显错误,则应查看是否有词语搭配错误,易混词错误、词性错误等等细节错误。
4、如果错行中既不存在语法错误,也不存在词汇错误,则从整体上查看上下文意思是否连贯,连接词是否使用正确,是否有逻辑混乱的现象,如否定句误用成肯定句造成句意不通等。注意:有时没有错项的行对改错很有帮助。
5、找到错误项之后,按要求形式进行改正、删去或增添,并设法找到一个正确项使句子在语法、语义和逻辑上都成立。
The hunter-gatherer tribes that today live as our prehistoric 1.______
human ancestors consume primarily a vegetable diet supplementing 2._____
with animal foods. An analysis of 58 societies of modem hunter-
gatherers, including the Kung of southern Africa, revealed that one
half emphasize gathering plant foods, one-third concentrate on fishing
and only one-sixth are primarily hunters. Overall, two-thirds
and more of the hunter-gatherer’s calories come from plants. Detailed 3.______
studies of the Kung by the food scientists at the University of
London, showed that gathering is a more productive source of food
than is hunting. An hour of hunting yields in average about 100 4.______
edible calories, as an hour of gathering produces 240. 5.______
Plant foods provide for 60 percent to 80 percent of the Kung 6._______
diet, and no one goes hungry when the hunt fails. Interestingly, if
they escape fatal infections or accidents, these contemporary
aborigines live to old ages despite of the absence of medical care. 7._______
They experience no obesity, no middle-aged spread, little dental
decay, no high blood pressure, on heart disease, and their blood
cholesterol levels are very low( about half of the average American 8._______
adult), if no one is suggesting what we return to an aboriginal life 9.________
style, we certainly could use their eating habits as a model for 10.________
healthier diet.

The grammatical words which play so large a part in English
grammar are for the most part sharply and obviously different 1._______
from the lexical words. A rough and ready difference which may
seem the most obvious is that grammatical words have“ less
meaning”, but in fact some grammarians have called them 2._______
“empty” words as opposed in the “full” words of vocabulary. 3.________
But this is a rather misled way of expressing the distinction. 4._________
Although a word like the is not the name of something as man is,
it is very far away from being meaningless; there is a sharp 5._________
difference in meaning between “man is vile and” “the man is
vile”, yet the is the single vehicle of this difference in meaning. 6.________
Moreover, grammatical words differ considerably among
themselves as the amount of meaning they have, even in the 7.________
lexical sense. Another name for the grammatical words has been
“little words”. But size is by no mean a good criterion for 8._________
distinguishing the grammatical words of English, when we
consider that we have lexical words as go, man, say, car. Apart 9.________
from this, however, there is a good deal of truth in what some
people say: we certainly do create a great number of obscurity 10.________
when we omit them. This is illustrated not only in the poetry of
Robert Browning but in the prose of telegrams and newspaper headlines.

8. 答案:mean → means
9. 答案:∧ lexical → such 或在words后加such,或把改成like
10. 答案:number → deal / amount
During the early years of this century, wheat was seen as the
very lifeblood of Western Canada. People on city streets watched
the yields and the price of wheat in almost as much feeling as if 1._______
they were growers. The marketing of wheat became an increasing 2._______
favorite topic of conversation.
War set the stage for the most dramatic events in marketing
the western crop. For years, farmers mistrusted speculative grain
selling as carried on through the Winnipeg Grain Exchange.
Wheat prices were generally low in the autumn, so farmers could 3._______
not wait for markets to improve. It had happened too often that
they sold their wheat soon shortly after harvest when farm debts 4.________
were coming due, just to see prices rising and speculators getting rich. 5._______
On various occasions, producer groups, asked firmer control, 6._______
but the government had no wish to become involving, at 7.______
least not until wartime when wheat prices threatened to run
wild.
Anxious to check inflation and rising life costs, the federal 8.______
government appointed a board of grain supervisors to deal with
deliveries from the crops of 1917 and 1918. Grain Exchange
trading was suspended, and farmers sold at prices fixed by the
board. To handle with the crop of 1919, the government appointed 9.______
the first Canadian Wheat Board, with total authority to 10.______
buy, sell, and set prices.
