Passage One
As any homemaker who has tried to keep order
at the dinner table knows, there is far more to a family meal than food.
Sociologist Michael Lewis has been studying 50 families to find out just how
much more。
Lewis and his co-workers carried out their
study by videotaping the families while they ate ordinary meals in their own
homes. They found that parents with small families talk actively with each
other and their children. But as the number of children gets larger,
conversation gives way to the parents’ efforts to control the loud noise they make. That can have an
important effect on the children. “In general the more question-asking the parents do, the higher the
children’s IQ scores,” Lewis says. “And the more children there are, the less
question-asking there is. ”
The study also provides an explanation for
why middle children often seem to have a harder time in life than their
siblings. Lewis found that in families with three or four children, dinner
conversation is likely to center on the oldest child, who has the most to talk
about, and the youngest, who needs the most attention. “Middle children are invisible,” says Lewis. “When you see someone get up from the
table and walk around during dinner, chances are that it’s the middle child. ” There is, however, one thing that stops
all conversation and prevents anyone from having attention: “When the TV is on,” Lewis says, “dinner is a non-event. ”
21. The writer’s purpose in writing the text is to 。
A. show the relationship between parents
and children
B. teach parents ways to keep order at the
dinner table
C. report on the findings of a study
D. give information about family problems
22. Parents with large families ask fewer
questions at dinner because 。
A. they are busy serving food to their
children
B. they are busy keeping order at the
dinner table
C. they have to pay more attention to
younger children
D. they are tired out having prepared food
for the whole family
23. By saying “Middle children are invisible” in paragraph 3, Lewis means that middle
children 。
A. have to help their parents to serve
dinner
B. get the least attention from the family
C. are often kept away from the dinner
table
D. find it hard to keep up with other
children
24. Lewis’ research provides an answer to the question 。
A. why TV is important in family life
B. why parents should keep good order
C. why children in small families seem to
be quieter
D. why middle children seem to have more
difficulties in life
25. Which of the following statements would
the writer agree to?
A. It is important to have the right food
for children。
B. It is a good idea to have the TV on
during dinner。
C. Parents should talk to each of their
children frequently。
D. Elder children should help the younger
ones at dinner
参考答案及解析
21. [答案]C
[解析]主旨大意题。
22. [答案]B
[解析]文章第二段提到conversation gives
way to the parents’ efforts to control the loud noise
they make. 故正确答案应该选择B。
23. [答案]B
[解析]文章第三段提到 Lewis found that in
families with three or four children, dinner conversation is likely to center
on the oldest child, who has the most to talk about, and the youngest, who
needs the most attention. 可以看出老大和老小都是谈话的焦点,只有中间的孩子是被人忽视的。
24. [答案]D
[解析]推理判断题。Lewis的研究表明中间的孩子不受重视,可以推断出这对他们将来的生活会造成一定的影响。
25. [答案]C
[解析]对错判断题。A原文没有提到,B和D可以用排除法排除。

下面小编为大家准备了 研究生入学 的相关考题,供大家学习参考。
B.插入
C.点突变
D.重排
由于密码子的连续性,在开放阅读框中发生插入或缺失1个或2个碱基的基因突变,都会引起mRNA阅读框架发生移动,称为移码,使后续的氨基酸序列大部分被改变,其编码的蛋白质彻底丧失功能,称为移码突变(A、B错)。重排使氨基酸序列整体发生变化,不可能仅改变一个氨基酸(D错)。点突变即单个碱基置换可以造成改变氨基酸编码的错义突变(C对)。
A.少突胶质细胞围绕变性神经细胞 B.小胶质细胞吞噬变性神经细胞
C.小胶质细胞和中性粒细胞吞噬变性神经细胞 D.淋巴细胞围绕小血管浸润
B.人与自然界是两个完全分离的世界
C.人类世界是人的实践活动在自在世界基础上建造的属人世界
D.人与自然的关系是思维与存在的关系
【正确分析】人类世界与人的活动不可分离:人化自然是被人的活动改造过的自然,它体现了人的需要、目的、意志和本质力量;人的社会关系则是人的活动的对象化。人不断通过自己的实践活动在自在世界的基础上建造属人世界,属人世界是人的实践活动的对象化,是人的对象世界。马克思原文强调的是,与人的实践活动无关的自在世界,对人类来说是毫无意义的,人是生活在自己创造的属人世界之中。当然,这并不意味着马克思否定自然界的先在性,这个命题是建立在物质第一性原理基础之上的。因此,本题的正确答案是C选项。
【干扰分析】A选项自然界具有客观实在性。B选项人与自然不相分离,人在遵循自然规律的基础上认识和改造自然。D选项把人与自然的关系看作是思维与存在的关系不正确。
