Pessimistic,anxious and depressed people may have a higher risk of dementia (痴呆),US researchers reported on Thursday.
A study of a group of 3,500 people showed that those who scored high for pessimism on a standardized personality test had a 30 percent increased risk of developing dementia 30 to 40 years later.
Those scoring very high on both anxiety and pessimism scales had a 40 percent higher risk,the study showed.
“There appears to be a dose­response pattern.That is,the higher the scores,the higher the risk of dementia,”Dr Yonas Geda,a neuropsychiatrist at the Mayo Clinic in Rochester,Minnesota who led the study,said in a statement.
Geda and his colleagues looked at the medical records of 3,500 men and women who lived near the clinic between 1962 and 1965.
They all took the Minnesota Multiphasic Personality Inventory,a standard personality and life experience test,Geda’s team told a meeting of the American Academy of Neurology in Miami.
In 2004,the team interviewed the participants or family members.
Those who scored higher for anxiety and pessimism on the test were more likely,as a group,to have developed dementia by 2004,including Alzheimer’s disease and vascular (血管的) dementia.
This did not mean a person who is pessimistic could assume he or she has a higher risk of developing dementia.
“One has to be cautious in interpreting a study like this,”Geda said.
“One cannot make a leap from group level data to the individual.Certainly the last thing you want to do is to say,‘Well,I am a pessimist;thus,I am doomed to develop dementia 20 or 30 years later,’because this may end up becoming a self­fulfilling prophecy (预言).”
And there is NOT any specific way to prevent dementia,although many studies have shown that a healthy diet,exercise,keeping active in other ways,doing puzzles and other activities lower the risk.
小题1:What is the passage mainly about?
A.It is impossible for people to avoid dementia.
B.People who always have negative feelings may have a higher risk of getting dementia.
C.If we have a healthy diet,we would have no chance of getting dementia.

小题2:According to the passage,which of the following is TRUE?
A.There are many ways to prevent dementia effectively.
B.A person who is pessimistic is sure to get dementia.
C.Those who lead a happy life will not get dementia when they are old.
D.Those who scored high for pessimism might have a higher risk of dementia.
小题3:Which of the following does NOT help reduce the risk of getting dementia according to the passage?
A.A healthy diet.B.Proper exercises.
C.Doing puzzles.D.Getting up early.
小题4:Which of the following words is not close to the meaning of the word “pessimistic”?
A.Cheerless.B.Optimistic.
C.Unhappy.D.Upset.

答案

小题1:B
小题2:D
小题3:D
小题4:B
解析

小题1: B
解析 主旨大意题。文章第一段就点明了主题,整篇文章都围绕悲观、压抑等情绪更容易使人患痴呆症这一论断展开。
小题2: D
解析 细节理解题。由最后一段可知A项错误;悲观者患痴呆症的可能性会更大而不是一定会患痴呆症,所以B项错误,D项正确;生活幸福的人也不一定就一定不会患痴呆症。
小题3: D
解析 细节理解题。最后一段提到健康饮食、常运动、猜字谜等有助于预防痴呆,而文中并没有涉及到有关“早起床”的信息。
小题4: B
解析 词义猜测题。由文章知,pessimistic与anxious和depressed意义接近,而A、C、D三项与这两个词的意思也接近,只有optimistic意为“乐观的”,与pessimistic意义相反。

The library is one of the most popular places at a western university.Students turn to it for research,conversations about class,and many other services.
Compared with Chinese libraries,college libraries in the US and UK tend to offer more resources.A postgraduate at Yale University can borrow as many as 225 books at a time.
In addition to borrowing books,there are online and electronic resources.These include a database search of popular and academic material,such as LexisNexis Academic,which offers items from newspapers and magazines.
Although books and articles are the items that students ask for most frequently,some libraries provide audio and video recordings,maps and sheet music(活页乐谱).At some schools,teachers and tutors put electronic copies of their teaching PPTs on the library web to give easier access for students.
Another useful service in western college libraries is the Interlibrary Loan.This allows a student at one school to borrow books from another school.The loan request is made through the student’s college library,which gets the book,gives it to the user,and arranges for its return.
Technology has brought more services to students and has made libraries attractive.Some universities have services for students to send messages through the computer or mobile texts to ask the library staff for information.
Earlier this year,Harvard University introduced a new Scan and Deliver service,allowing students to make requests for parts of books and articles.Requests made through the system are handled by library staff.The student receives an e­mail with an Internet link to the scanned pages.The service is free and all material comes within four days.
It used to be that libraries didn’t allow food or drinks.But that rule is changing and many of them now contain a café so students can spend as much time as they want in the library.
Actually,some US university libraries are now all­night affairs,or have at least one study room open all night.

Boiler rooms are often dirty and steamy,but this one is clean and cool.Fox Point is a very new 47­unit living building in South Bronx,one of the city’s poorest areas.Two­thirds of the people living there are formerly (以前) homeless people,whose rent is paid by the government.The rest are low­income families.The boiler room has special equipment,which produces energy for electricity and heat.It reuses heat that would otherwise be lost to the air,reducing carbon emissions(碳排放)while also cutting costs.
Fox Point is operated by Palladia,a group that specializes in providing housing and services to needy people.Palladia received support from Enterprise Community Partners (ECP),which helps build affordable housing by providing support to housing developers.
ECP has created national standards for healthy,environmentally (环境方面) clever and affordable homes which are called the Green Communities Standards.These standards include water keeping,energy saving and the use of environmentally friendly building materials.Meeting the standards increases housing construction costs by 2%,which is rapidly paid back by lower running costs.Even the positioning of a window to get most daylight can help save energy.
Michael Bloomberg,New York’s mayor,plans to create 165,000 affordable housing units for 500,000 New Yorkers.Almost 80% of New York City’s greenhouse gas emissions come from buildings,and 40% of those are caused by housing.So he recently announced that the city’s Department of Housing and Preservation and Development (DHPD),whose duty is to develop and keep the city’s supply of affordable housing,will require all its new projects to follow ECP’s green standards.
Similar measures have been taken by other cities,such as Cleveland and Denver,but New York’s DHPD is the largest city developer of affordable housing in the country.(2010·四川,B)
小题1:What is the purpose of describing the boiler rooms in the first paragraph?
A.To explain the measures the city takes to care for poor people.
B.To suggest that affordable housing is possible in all areas.
C.To show how the environment­friendly building works.
D.To compare old and new boiler rooms.
小题2:What is an advantage of the buildings meeting the Green Communities Standards?
A.Lower running costs.
B.Costing less in construction.
C.Less air to be lost in hot days.
D.Better prices for homeless people.
小题3:It can be learned from the text that________.
A.New York City is seriously polluted
B.people’s daily life causes many carbon emissions in New York City
C.a great number of people in New York City don’t have houses to live in
D.some other cities have developed more affordable housing than New York City
小题4:What is the main purpose of this text?
A.To call on people to pay more attention to housing problems.
B.To prove that some standards are needed for affordable housing.
C.To ask society to help homeless people and low­income families.
D.To introduce healthy,environmentally clever and affordable housing.

Almost every machine with moving parts has wheels,yet no one knows exactly when the first wheel was invented or what it was used for.We do know,however,that they existed over 5,500 years ago in ancient Asia.
The oldest known transport wheel was discovered in 2002 in Slovenia.It is over 5,100 years old.Evidence suggests that wheels for transport didn’t become popular for a while,though.This could be because animals did a perfectly good job of carrying farming tools and humans around.
But it could also be because of a difficult situation.While wheels need to roll on smooth surfaces,roads with smooth surfaces weren’t going to be constructed until there was plenty of demand for them.Eventually,road surfaces did become smoother,but this difficult situation appeared again a few centuries later.There had been no important changes in wheel and vehicle design before the arrival of modern road design.
In the mid­1700s,a Frenchman came up with a new design of road—a base layer(层) of large stones covered with a thin layer of smaller stones.A Scotsman improved on this design in the 1820s and a strong,lasting road surface became a reality.At around the same time,metal hubs (the central part of a wheel)came into being,followed by the pneumatic tyre(充气轮胎) in 1846.Alloy wheels were invented in 1967,sixty years after the appearance of tarmacked roads(柏油路).As wheel design took off,vehicles got faster and faster.                          (2013·重庆,C)
小题1:What might explain why transport wheels didn’t become popular for some time?
A.Few knew how to use transport wheels.
B.Humans carried farming tools just as well.
C.Animals were a good means of transport.
D.The existence of transport wheels was not known.
小题2:What do we know about road design from the passage?
A.It was easier than wheel design.
B.It improved after big changes in vehicle design.
C.It was promoted by fast­moving vehicles.
D.It provided conditions for wheel design to develop.
小题3:How is the last paragraph mainly developed?
A.By giving examples.
B.By making comparisons.
C.By following time order.
D.By making classifications.
小题4:What is the passage mainly about?
A.The beginning of road design.
B.The development of transport wheels.
C.The history of public transport.
D.The invention of fast­moving vehicles.

When you consider what subject to study in college, chances are that you and your parents will think about what you can make out of it after graduation. You will likely ask the question: “Can I find a well-paid job or simply a job with a degree in this in the future?”
This consideration also influences students when they come to choose between studying science or humanities (人文学科) at college. People generally believe that the humanities, which include literature ,  history, cultural studies and philosophy,  do not prepare students for a specific vocation (职业). Science subjects, however, are considered vocational courses that produce scientists, engineers and economists (经济学家).
“I"ve decided to take finance as my college major. My parents and I think this subject will help me get a good job or start a business,” said Huachen Yueru, 17, a science student at Wuxi No. 1 High School.
Even those who choose a liberal arts (文科) education often pick the humanities subject which they think will best help them later find a job.
“I"m going to study Spanish in college, which I believe will open doors to a high-paying job for me,” said Liu Chao, 18, a Senior 2 student at Dalian No 20 High School. He said few of his classmates show interest in subjects like philosophy and history, which are seen as “less promising” in job markets.
The popularity of liberal arts subjects among college students has also been decreasing in the United States. American scholars (学者) and universities are concerned that in the ongoing economic crisis (经济危机) liberal arts subjects will be hit hardest. As money tightens (紧缩), they worry that the humanities may become “a great luxury (奢侈品) that many cannot afford”, according to the New York Times.
小题1: When you consider what to study in college, what does you and your parents usually think about ?
A.whether you are interested in the subject.
B.if you can lead a happy life.
C.what you can make out of it after graduation.
D.How much you can learn in the college.
小题2:Why do students show little interest in the subjects, like philosophy or history ?
A.Because they are not interested in them.
B.Because they think these subjects are useless.
C.Because they see these subjects as less-promising in job market.
D.Because they like the science subjects.
小题3: What can we infer from the passage ?
A.Humanities are becoming less and less popular with the students.
B.Studying science subjects is sure to find a well-paid job.
C.The humanities in college should be cancelled.
D.The writer thinks those who choose the liberal arts education will choose their favorite subjects.
小题4: What does the underlined word “it” refer to in the first paragraph ?
A.the subject you study in collegeB.scienceC.humanitiesD.liberal arts

Disposing(处理)of waste has been a problem since humans started producing it.As more and more people choose to live close together in cities,the waste-disposal problem becomes Increasingly difficult.
During the eighteenth century,it was usual for several neighboring towns to get together to select a faraway spot as a dump site.Residents or trash haulers(垃圾拖运者)would transport household rubbish,rotted wood,and old possessions to the site.Periodically(定期的)some of the trash was burned and the rest was buried.The unpleasant sights and smells caused no problem because nobody lived close by.
Factories,mills,and other industrial sites also had waste to be disposed of.Those located on rivers often just dumped the unwanted remains into the water.Others built huge burners with chimneys to deal with the problem.
Several facts make these choices unacceptable to modern society.The first problem is space Dumps,which are now called landfills,are most needed in heavily populated areas.Such areas rarely have empty land suitable for this purpose.Property is either too expensive or too close to residential(住宅区的) neighborhoods.Long-distance trash hauling has been a common practice but once farm areas are refusing to accept rubbish from elsewhere,cheap land within trucking distance of major city areas is almost nonexistent.
Awareness(意识) of pollution dangers has resulted in more strict rules of waste disposal. Pollution of rivers,ground water,land and air is a price people can no longer pay to get rid of waste. The amount of waste,however,continues to grow.
Recycling efforts have become commonplace,and many towns require their people to take part.Even he most efficient recycling programs,however,can hope to deal with only about 50 Percent of a city’s reusable waste.
小题1:The most suitable title for this passage would be _______.
A.Places for Disposing WasteB.Waste Pollution Dangers
C.Ways of Getting Rid of WasteD.Waste Disposal Problem
小题2:During the 18th century,people disposed their waste in many ways EXCEPT for _______.
A.burying itB.recycling it
C.burning itD.throwing it into rivers
小题3:What can be inferred from the fourth paragraph?
A.Farm areas accept waste from the city in modern society.
B.There is cheap land to bury waste in modern society.
C.It is difficult to find space to bury waste in modern society.
D.Ways to deal with waste in modern society stay the same.
小题4:The main purpose of writing this article is to _______.
A.draw people’s attention to waste management
B.warn people of the pollution dangers we are facing
C.call on people to take part in recycling programs
