There are two factors which determine an individual's intelligence. The first is the sort of brain he is born with. Human brains differ considerably, some being more capable than others. But no matter how good a brain he has to begin with, an individual will have a low order of intelligence unless he has opportunities to learn. So the second factor is what happens to the individual—the sort of environment in which he is reared (培养). If an individual is handicapped (妨碍) environmentally, it is likely that his brain will fail to develop and he will never attain the level of intelligence of which he is capable.

The importance of environment in determining an individual's intelligence can be demonstrated by the case history of the identical twins, Peter and Mark X. Being identical, the twins had identical brains at birth, and their growth processes were the same. When the twins were three months old, their parents died, and they were placed in separate foster homes. Peter was reared by parents of low intelligence in an isolated community with poor educational opportunities. Mark was reared in the home of well-to-do parents who had been to college. He was read to as a child, sent to good schools, and given every opportunity to be stimulated intellectually. This environmental difference continued until the twins were in their late teens, when they were given tests to measure their intelligence. Mark's I.Q. was 125, twenty-five points higher than the average and fully forty points higher than his identical brother. Given equal opportunities, the twins, having identical brains, would have tested at roughly the same level.

1.This passage can be best titled_________.

A.Intelligence and Environment

B.Measuring Your Intelligence

C.The Case of Peter and Mark

D.How the brain Influences Intelligence

2.According to the passage, the average I.Q. is _____.

A.85 B.125 C.110 D.100

3.The case history of the twins appears to support the conclusion that _______.

A.individual with identical brains seldom test at same level

B.an individual's intelligence is determined only by his environment

C.changes of environment produce changes in the structure of the brain

D.lack of opportunity blocks the growth of intelligence

4.This passage suggests that an individual's I.Q.______.

A.can be increased by education

B.stays the same throughout his life

C.can be predicted at birth

D.is determined by his childhood

 

1.A 2.D 3.D 4.A 【解析】 本文是说明文。文章讲的是智力和环境的关系。同样智力水平的人,环境和教育不一样,智商也会有很大不同。 1.主旨大意题。从每段的段首,可以看出这篇文章讲的是智力和环境的关系。由此可知,A项Intelligence and Environment(智力与环境)可以做本文标题。故选A。 2.细节理解题。从最后一段的句子Mark's I.Q. was 125, twenty-five points higher than the average(马克的智商是125,比平均水平高出25分,比他的同卵兄弟整整高出40分)可知,平均智商是125-25=100。故选D。 3.推理判断题。从文章的最后一段的句子Given equal opportunities, the twins, having identical brains, would have tested at roughly the same level.(如果机会均等,这对拥有相同大脑的双胞胎的测试结果会大致相同)可推知,彼得比马克的测试结果低是因为彼得缺少机会。由此可知,缺乏机会阻碍智力发展。故选D。 4.细节理解题。根据第二段的句子Mark was reared in the home of well-to-do parents who had been to college. He was read to as a child, sent to good schools, and given every opportunity to be stimulated intellectually.(马克是在上过大学的富裕家庭中长大的。当他还是个孩子的时候,人们就给他读书,送他去好学校,给他一切机会来激发他的智力)可知,人的智商是可以通过教育提高的。故选A

    As the international demand for narrative(叙事的) film/TV content continues to increase with popular streaming services like Netflix and others the two questions then come: will the coming generations receive most of their entertainment through visual means rather than through the written word and will such an increase of narrative film/ TV reduce the importance of reading?

Growing examples of this trend include the diminishment(减少) of fiction in the common core (核心的)curriculum, the everrising culture of computer games, the wave of streaming services of wide international reach, and movies filled with special effects made for children and teenagers. Nor must we ignore the economic dangers that lie ahead for the written word. The narrative film industry is a moneymaker that dwarfs(使相形见绌) the publishing industry.

The other underlying question, of course, is “does it really matter if the written word bows to the world of film/TV?” From my point of view, any diminishment of fiction delivered by words is a loss for mankind.

There is no greater human feature than the imagination. It lies at the very soul of the human species. It is the brain’s most powerful engine. It is the essential muscle of life and like all muscles it must be exercised and strengthened.

Writing and reading are the principal tools that inspire, create and empower our imagination. Anything that diminishes that power is the enemy of mankind.

It should be known that I am not opposed to new media and technological advances. Instead, I have always felt it necessary to adapt to advancing technology. In fact, a number of my novels are in various stages of development for film, TV, and live stage productions. My hope is that the written word will only stand to be complemented(补充)by its visual counterparts(对应物), not pushed to the edge of extinction.

Of course, there are those who will present arguments for the superiority of the moving image over the written word. Each has its place. My argument is for finding the right balance between it and the moving image.

1.In what way does narrative film/TV embarrass the written word?

A.Economic benefits B.International reach

C.Cultural influence D.Educational importance

2.Why does the author value the role of the written word?

A.It strengthens our muscles. B.It helps sharpen imagination.

C.It distinguishes man from each other. D.It paves the way for narrative film/TV.

3.What is the author’s attitude towards technology?

A.Cautious B.Skeptical

C.Positive D.Critical

4.What’s the author concerned about?

A.The fate of reading. B.The extinction of fiction.

C.The impact of the written word. D.The future of the moving image.

I went to Arizona earlier this month to see what the college of the future might look like. What I found is an exciting new era of higher education that will help more students get a great, personalized education at an affordable price.

This future may not always include the lecture halls, dormitories, and other features of the traditional college experience. Instead, the colleges I visited are experimenting with ways for students to get their degrees online, allowing them to take courses any place and at any time.

These “colleges without walls” as they are sometimes called, are at the forefront of the effort to broaden access to higher education, especially for low-income students with full-time jobs and families. During my visit, I heard encouraging stories of students who were taking advantage of these flexible learning models to pursue degrees that could put them on paths to new careers.

One of those students was Shawn Lee. He had a compelling story: After dropping out of college decades ago, he found himself in a series of low-paying, often back-breaking jobs. He recently decided to get his degree when he had his first child and wanted to start building a better life.

Tucked away in an industrial park in Tempe, Rio Salado didn’t look much like a traditional institute of higher education. There were no students running to class. Just a couple of glass-faced office buildings. The college had just 22 full-time faculty serving 60,000 students, with more than half of them attending classes online.

Several students I met during my visit said they liked learning online. “I’ve taken college classes in a big auditorium with herds of people. There was no personal connection,” one student said. “Now I can reach my teacher with the click of a mouse.”

After several days’ visit, I left Arizona feeling quite optimistic about what the future holds for higher education.

1.What does “colleges without walls” in the third paragraph refer to?

A.Colleges that have no walls around.

B.Colleges that students attend online.

C.Colleges that can be entered freely.

D.Colleges that give students more freedom.

2.What made Shawn Lee return to attend college again?

A.That he has nothing to do.

B.That he couldn’t find a job.

C.That the cost of the college is low.

D.That he wanted to find a better job.

3.How did the writer feel after the visit?

A.Hopeful. B.Dissatisfied. C.Disappointed. D.Upset.

4.What is the writer’s purpose by writing this passage?

A.To explain what “colleges without walls” are.

B.To advertise the colleges.

C.To encourage people to attend higher education.

D.To introduce a new model of education.

阅读下面短文,根据所给情节进行续写,使之构成一个完整的故事。

The canteen was crowded with summer campers from high schools across the city, all extremely hungry after a day's activities. I spotted an empty place and walked there. Just as I put my tray(餐盘) down, I felt a bump against my hip. The tray dropped on the table and the soup spilt all over my camp shirt and jeans. And I heard a burst of laughter.

"Can’t you look where you are going, you clumsy fool!" I shouted, glaring at the troublemaker, a tall boy with wild hair.

"Sorry! Can't help laughing! You look so funny!" said the boy, bending over with laughter. I was too annoyed to respond and just walked away to change my clothes.

The next morning, we were all assembled for roll call(点名), when I saw the same boy come running out of the dorm, his unbuttoned shirt flying behind him. Before he could slide into place, he was spotted by the Camp Commandant. As a punishment for being late, he was made to do a hundred pushups. As I walked past him later, I let out a loud laugh, saying "Sorry. I can't help laughing. You look so funny."

So the war of words continued in the following three days with the wild-haired boy, whose name, I found out, was Ben.

A mountain hike(远足) marked the last day of the camp. On the way back, I found myself left far behind my team. Soon, they were out of sight. The camp site was a long way away and I was getting anxious as evening fell. I risked taking a shortcut(近路) clung to the mountain side, but suddenly, I tripped off the path and slid right down the slope(斜坡).

Fortunately, my fall was stopped by a bunch of bamboo. I saw I was about ten meters below the track. There was no way I could climb up the slope as evidently I had my ankle broken. After making several vain attempts, I waited hopelessly. It got dark and I became afraid.

注意:

1.所续写短文的词数应为150左右;

2.应使用5个以上短文中标有下划线的关键词语;

3.续写部分分为两段,每段的开头语已为你写好;

Then, I saw a faint light, and heard a voice calling out my name.
