Questions 21 to 25 to 25 are based on the following passage.For a clearer picture of what the student knows, most teachers use another
kind of examination in addition to objective tests. They use essay tests,which require students to write long answers to broad, general questions
such as the following: Mention several ways I which Benjamin Franklin hasinfluenced the thinking of people in his own country and in other parts of
the world. one advantage of the essay test is that it reduces the elementof luck. The student cannot get a high score just by making a lucky guess.
Another advantage is that it shows the examiner more abort the studentsability to put facts together into a meaningful whole. It should show how
deeply he has thought about the subject. Sometimes, though, essay tests gave disadvantages, too. Some students are able to write rather good answers
without really knowing much about the subject, while other students whoactually know the material have trouble expressing their ideas in the essay
form.Besides, in an essay test the students score may depend upon the examiners
feelings at the time of reading the answer. If he is feeling tired or bored,the student may receive a lower score than he should. Another examiner
reading the same answer might give it a much higher mark. Because of this,the objective test gives each student a fairer chance, and of course it
is easier and quicker to score.Whether an objective test or an essay test it used, problems arise. When
some objective questions are used along with some essay questions, however,a fairly clear picture of the students knowledge can usually be obtained.

passage TwoQuestions 26 to 30 are based on the following passage.
Around the world two thirds of the people are farmers. Most of them engagein subsistence farming. This means that they raise plants and animals to
furnish their families with food and other supplies. They consume theirvariedoutput and have little to sell or to trade for other goods.
Subsistence farms were common in the United States at on time, but there arefew such farms today.
Two thirds of American farmers practice commercial farming. Commercial farmsproduce about 97 per cent of the countrys agricultural goods. These farms
are operated much like other industries. The members of the farm familyproduce the commodities(商品)that will be sent to the market. They sell their
products and buy the things they need.Some commercial farms are big factories in the field. They may be owned by
company or by an individual as an investment. Most American farms, however,are still operated by families. A farmer may own or rent his land.
In a country as large as the United States, farms vary widely in climate,land surface, soil, water supply, convenience to market, and other
characteristics. Different regions may have different kinds of specializedfarms. Specialized farmers concentrate on the kind of farming best suited to
the land and climate, to their technical skills, and to the money theyinvest in the farm.
However, no region is limited to a single type of farm. Indeed few farms arelimited to one crop or commodity. Where out put is varied and no one kind of
crop or commodity produces more than half of a farms income, it isclassified as a general farm. The general farmer grows varied crops to use
the efferent kinds of soils or surfaces on his land and to employ his timeand machinery most efficiently.

Questions 31 to 35 are based on the following passage.No one knows for sure why birds migrate(定期迁徙).one theory of migration
says that ancient birds of the northern part of the earth were forcedsouthward during the Ice Age, when ice covered large parts of Europe, Asia
and North America. As the ice melted, the birds came back to theirhomelands, spent the summer, and then went south again in winter. Gradually,
these comings and goings became habits, and birds now migrate though much ofthe ice has gone.
Another theory proposes that the ancient home of all modern birds was thetropic areas. There lived so well that the region became overcrowded. Many
species had to move northward. During the summer, these birds found plentyof room and food. In winter, however, food became scarce and they had to
return to the south.A newer theory is that increasing daylight stimulates certain glands(腺)in
the birds body and prepares it for migration. one scientist is able to makebirds migrate in midwinter by ex posing them for two months to artificial
daylight. Recoveries of marked birds indicate that they fly north as soon asthey are set free. The conclusion is that the urge to migrate is determined
by changes in the birds body which take place under seasonal changes in thelength of daylight.
This theory would account for the fact that not all birds migrate at thesame time. Each species seems to have its own schedule. The theory would
also account for the regular time and routes of migration. Birds arrive at agiven place year after year.
Unfavorable weather delays them only a few days. Total hours of daylight,rather than weather, start them on the way.
How birds find their way to the same place year and why they follow theirown particular route are still mysteries. They evidently do not follow known
landmarks(地面标志),for many young birds migrate alone without the help ofexperienced adults.
31.We can conclude from the first paragraph that ______.[A]during the Ice Age, the whole Europe was covered with ice
