精英家教網 > 高中英語 > 題目詳情

Since many of you are planning to study at a college or university in this country, you may be curious to know what you usually do in a typical week, how you can get along with your fellow students, and so on. These are the questions I want to discuss with you today.

First, let’s talk about  what your weekly schedule will look like. No matter what your major may be, you can expect to spend between four and six hours a week for each class attending lectures. Lectures are usually in very large rooms because some courses such as introduction to sociology or economics often have as many as two or three hundred students, especially at large universities. In lectures, it’s very important for you to take notes on what the professor says because the information a lecture is often different from the information in your textbooks. Also, you can expect to have exam questions based on the lectures. So it isn’t enough to just read your textbooks; you have to attend lectures as well. In a typical week you will also have a couple of hours of discussion for every class you take. The discussion section is a small group meeting usually with fewer than thirty students where you can ask questions about the lectures, the reading, and the homework. In large universities, graduate students, called teaching assistants, usually direct discussion sections.

If your major is chemistry, or physics, or another science, you’ll also have to spend several hours a week in the lab, or laboratory, doing experiments. This means that science majors spend more time in the classroom than non science majors do. On the other hand, people who major in subjects like literature or history usually have to read and write more than science majors do.

1.The main purpose of this text is       .

A.to persuade the students to attend lectures

B.to encourage the students to take part in discussions

C.to advise the students to choose proper majors

D.to help the students to learn about university life.

2.We can learn from the passage that university professors       .

A.spend about 5 hours on lectures each week

B.must join the students in the discussion sections

C.require the students to read beyond the textbooks

D.prefer to use textbooks in their lectures

3.A discussion section does NOT include       .

A.talking over what the students have read about the courses

B.working under the guidance of university professors

C.discussing the problems related to the students’ homework

D.raising questions about what a professor has said in a lecture

4.According to the author, science majors       .

A.read and write less than non science majors

B.have to work harder than non science majors

C.spend less time on their studies than non science majors

D.consider experiments more important than discussions

科目:高中英語 來源:2015屆遼寧省錦州市高一12月月考英語試卷(解析版) 題型:閱讀理解

The poorer mental function seen among alcoholics,many of whom also regularly smoke cigarettes,may be partly due to the long term effects of nicotine(尼古丁),new research suggests.

“People who are also smokers are at a much higher risk,” Dr.Jennifer  M.Glass of the University of Michigan's Addiction Research Center said. In her study,“Cigarette smoking has a bad effect on IQ and thinking,” she said.

This finding may seem counterintuitive(違反直覺的),since many smokers show that they feel quicker and focused after smoking. Indeed,research shows that improved mental functioning is one of the immediate effects of nicotine exposure. Chronic(慢性的)smokinghoweveris known to have the opposite effect. Studies show that up to 87 percent of alcoholics smoke cigarettes.

Yet,few studies have looked into cigarette smoking as a factor that might explain the cognitive(認知的)lack reported among alcoholics. To search for that association,Glass and her colleagues examined brain function among 172 men from the same area,including 103 men who abused alcohol. The team found that men with higher scores on the lifetime alcohol problems scale(LAPS)and those who reported a higher number of pack years of smoking both had lower IQ scores.

Upon further research,the researchers found that smoking also appeared to be independently associated  with weaker word and space reasoning.

Thus,though smoking did not account for all of the decreased mental functioning observed among the alcohol abusers,it did seem to account for some of the effects,the report indicates.

1.What is the passage mainly about?

A.Cigarette smoking contributes to decreased IQ and thinking.

B.Alcohol abuse is to blame for the poorer mental function.

C.Most of the alcoholics are also heavy smokers.

D.Non-smokers mostly have higher IQ scores.

2.The underline sentence “Chronic smoking, however, is known to have opposite effect” in paragraph 3  suggests:

A.Chronic smoking can improve mental functioning.

B.Chronic smoking has an immediate influence on mental functioning.

C.Chronic smoking has side effect on mental functioning improvement.

D.Chronic smokers feel quicker and focused after smoking.

3.From the passage we can learn that .

A.cigarette smoking is not related to reasoning

B.nicotine exposure can improve mental functioning temporarily

C.the long term effects of nicotine cause alcoholics

D.men with lower scores on the LAPS have lower IQ scores

4.It can be inferred from the passage that .

A.many alcoholics suffer a great deal from smoking

B.giving up smoking is significantly challenging for the alcoholics

C.alcoholics who do not smoke much have higher IQ scores

D.other factors can cause the poorer mental functioning besides smoking

5.The purpose of this passage is .

A.to warn us of the bad effects of smoking on IQ and thinking

B.to tell us why people are addicted to smoking

C.to give us some advice on how to improve IQ and reasoning

D.to compare the bad effects of alcohol and cigarette

Three—quarters of a million tourists flock to the white beaches every year,but this booming industry has come at a price.Poisonous smoke rising from open fires,rubbish made up of plastic bottles,packets…it’S a far cry from the white sands,clear waters and palm trees that we associate with the Maldives(馬爾代夫),the paradise island holiday destination set in the Indian Ocean.

of its 200 inhabited islands,which are spread across an area of"35,000 square miles,99 are good resorts(旅游勝地).So many tourists come every year,more than double the local population.Of these,over l 00,000 travel from the U K.The capital,Mal6,is four times more densely populated than London.Given these facts,it’S hardly surprising that the Maldives has a waste disposal problem.

Y ears a90,when the tourists left,the government had to deal with a stream of rubbish.Their solution was to turn one of the islands into a dumping ground.Four miles west of Mal6 is the country’s dumping ground,Thilafushi.What you are seeing here is a view of the Maldives on which no honeymooners will ever clap eyes.Each visitor produces 3.5 kg of waste per day.The country dumps more than 330 tons of rubbish on the island every day.

Now,since many waste boats,fed up with waiting seven hours or more,directly offload their goods into the sea,the government of the Maldives has banned the dumping of waste on the island.S0,the waste boats ship the rubbish to India instead.

1.What is the main cause of the waste disposal problem?

A.The big local population.                B.Too many waste boats.

C.The large number of tourists.             D.Open fires on the islands.

2.The underlined part can probably be replaced by“——”.

A.it’s quite similar to                     B.it’S a long distance from

C.it’s a loud shout from                   D.it’S totally different from

3.What can we learn from the text?

A.It iS much more crowded in Mal6 than in London.

B.Another island will be used as a dumping ground.

C.No honeymooners are willing to visit the Maldives.

D.Waste on islands will be offloaded directly into the sea.

4.What’S the author’S purpose in writing the text?

A.To attract more tourists to the Maldives.

B.To state the waste disposal problem in the Maldives.

C.To call on us to protect the environment.

D.To explain the causes of pollution in the Maldives.
