13.People born in winter are more likely to suffer mental health disorders,according to a recent study carried out by researchers at Vanderbilt University in Tennessee.
Researchers raised baby mice from birth to weaning (断奶) in either"summer"light cycles of 16 hours of light and 8 hours of dark or"winter"cycles of 8 hours of light and 16 hours of dark.A third group experienced 12 hours of light and 12 hours of dark a day.
Then half the winter mice stayed in a winter cycle,while half switched to a summer schedule.The summer mice were similarly split.The mice raised in equal periods of light and dark were split into three groups,one of which stayed on the 12hour schedule,one of which joined the winter group,and one of which joined the summer group.
After 28 days,it turns out the summerborn mice behaved the same whether they stayed on the summer cycle or switched to winter.But among the winterborn mice,those stayed in winter kept their previous schedule,while those that switched to summer stayed active for an extra hour and a half,which indicates that mice born and weaned in a winter light cycle showed dramatic disruptions in their biological clocks.
The finding is the first of its kind in mammals,and it could explain why people born in winter are at higher risk for mental health disorders including bipolar depression,schizophrenia and seasonal affective disorder.
"We know that the biological clock regulates mood in humans,"said study researcher McMahon."If the mechanism (机制) similar to the one that we found in mice operates in humans,the n it could not only have an effect on a number of behavioral disorders,but also have a more general effect on personality."
32.How many groups of mice are there finally in all in the experiment?
A
A.Seven.B.Six.C.Five.D.Four.
33.What's the main idea of the text?D
A.The biological clock regulates mood in humans.
B.People born in winter are at higher risk for physical health disorders.
C.The length of light will influence the behavior of the mice.
D.Being born in winter has a negative effect on people's mental health.
34.The underlined word"split"(Paragraph 3)can be replaced byB.
A.ended              B.divided            C.hit               D.torn
35.Who is the appropriate reader of the passage?C
A.A jobhunter.B.A student in the university.
C.A newlymarried couple.D.An experienced dentist.
A.A jobhunter.B.A student in the university.
C.A newlymarried couple.D.An experienced dentist.

1.The writer Margaret Mitchell is best known for writing Gone with the Wind,first published in 1936.Her book and the movie based on it,tell a story of love and survival during the American Civil War.Visitors to the Margaret Mitchell House in Atlanta,Georgia,can go where she lived when she started composing the story and learn more about her life.
Our first stop at the Margaret Mitchell House is an exhibit area telling about the writer's life.She was born in Atlanta in 1900.She started writing stories when she was a child.She started working as a reporter for the Atlanta Journal newspaper in 1922.One photograph of Ms.Mitchell,called Peggy,shows her talking to a group of young college boys.She was only about one and a half meters tall.The young men tower over her,but she seems very happy and sure of herself.The tour guide explains:"Now in this picture Peggy is interviewing some boys from Georgia Tech,asking them such questions as"Would you really marry a woman who works?"And today it'd be"Would you marry one who doesn't?"
The Margaret Mitchell House is a building that once contained several apartments.Now we enter the first floor apartment where Ms.Mitchell lived with her husband,John Marsh.They made fun of the small apartment by calling it"The Dup".
Around 1926,Margaret Mitchell had stopped working as a reporter and was at home healing after an injury.Her husband brought her books to read from the library.She read so many books that he bought her a typewriter and said it was time for her to write her own book.Our guide says Gone with the Wind became a huge success.Margaret Mitchell received the Pulitzer Prize for the book.In 1939the film version was released.It won ten Academy Awards,including Best Picture.

18.So much to do,so little time.So much information,so little time to read it.In this age there is more information than ever before.There is not enough time to read everything we want to read.However,you can consume more information in shorter time through speed-reading.
The first thing about speed-reading is looking at the word and recognizing it.Don't say the word in your mind,just look at it and recognize its importance.Later you will recognize clumps of four words or more to increase your speed.This is the first and most important step in speed-reading.
The next step is technique.As with any other skill,speed-reading requires technique.You should first be sitting up straight with your book flat on a horizontal (水平的) surface such as a table or a desk.Next,you should be able to see the entire page.This is necessary if you want to recognize clumps of words.Lastly,you should be focused.It is hard to read with a lot of noise.Find a quiet place to read.This will help your understanding of the text.
You need something to guide your eyes while reading.You should use your finger.Move your finger smoothly across the page.Keep your eyes focused on the words as you recognize them while using your finger as a guide.This will increase your speed.
The third step is practice.Practice makes perfect.Read using different techniques,but make sure you understand what you are reading.

28.From the first paragraph,we know thatB.
A.there is more limited information than ever before

c.Practise more.
A.c,a,b       B.c,b,a

C.a person should forget his difficulties while reading

5.As we know,it is common for people to catch a cold in winter and most people believe they know the reason for colds.However,scientists say people have some wrong beliefs about the cause of colds.
Many people think that once you get infected by colds,you will not be easy to be attacked by colds for the rest of your life.That's not the case.There are about 200 different viruses that cause the common cold.You catch a cold because of one kind of them this time,but you might catch a cold next time because of another.
Others believe that people get sick just because of the cold weather in winter.That is also wrong.
It's because people tend to stay closer in winter and the cold virus is transmitted from one person to another through handshakes,sneezing,or coughing.
While there is no actual cure for the common cold,scientists say there are still a few things you can do to help you.Some experts say honey and chicken soup are effective against colds.Especially honey.There is increasing evidence that it helps shorten the duration of the common cold sometimes even by two to three days particularly in children.Chicken soup also helps reduce the duration of the cold.
In addition,if you do have a cold and you don't feel like eating anything,it's not going to hurt you but you have to drink a lot and you can drink water or tea because doctors say the water cycle in your bodies helps to cure colds.That's very important.Though there is more than one way to deal with colds,doctors say the best advice is to continue using whatever works best for you.
61.We know from the second paragraph thatA.
A.colds can be caused by different viruses
B.there are people who never catch a cold
C.the common cold is caused by only one virus
D.all people are easily attacked by colds
62.The underlined word"transmitted"in the fourth paragraph means"C".
A.cured            B.changed      C.passed           D.caused
63.If you have a cold,you can do the following exceptB.
A.drinking a lot of water                 
C.forcing yourself to eat
C.eating honey                        
D.drinking chicken soups
64.It can be inferred from the passage thatA.
A.different people may have different ways to fight against colds
B.now scientists have found out practical treatment for colds
C.working in freezing weather is the main reason for colds
D.colds can be passed from animals to human beings.
