When we meet someone for the first time， we usually get an uncertain sense of what kind of person they are by the way they shake hands， talk， or walk． In the age of social networking， however， first impressions are sometimes made even before we actually meet someone in person - that is， by looking at their profile photos（头像）． 1.

In the study， a group of researchers from the University of Pennsylvania in the US used software to analyze the profile photos of 66，000 users of US social platform Twitter and 3，200 of their tweets． 2.The researchers wanted to find out if there was a relation between a person's profile photo and personality．

According to the results， open people are more likely to pose in an unusual way and use objects such as glasses or a guitar in their profile photo because they enjoy new and exciting experiences． Meanwhile， sensitive people often hide their negative emotions．3.Instead， they use an image of something like a pet， a car or a building． That's because sensitive people are strongly influenced by the strong social standard．

4.For example， outgoing people are found to have the most colorful profile images， as they want to emphasize their personality and show themselves off， the researchers wrote．

Although social media photos "usually represent oneself， they also allow a user to shape his or her own personality，" according to the researchers．5.After all， first impressions always last．

A．They want to show themselves off．

B．They try to avoid showing their faces．

C．We should make our profile photos available to others．

D．Some users were asked to complete a survey about their personality types．

E．According to a recent study， these social images say a lot about our personality．

F．When choosing a profile photo， we should think about what image we'd like to convey．

G．The colors used in profile photos also give us some information about the photo's owner．

Air pollution may be causing baldness, scientists have shown for the first time. A new study found that fine particulate matter emitted by cars would damage the skin that holds hair follicles (毛囊) in place. A series of laboratory tests on human cells showed that levels of the crucial proteins needed for hair to grow and be retained decreased when they were exposed to pollution particles. While there is a growing body of evidence showing how these tiny particles can damage internal health, including by entering the bloodstream through the lungs, this is the first to demonstrate such a risk to the surface of the body.

The study was conducted by exposing cells from the human follicle dermal papilla cells(HFDPCs), to various concentrations of PM10-like dust and diesel particles (柴油颗粒). After 24 hours the researchers performed a process, known as western blotting, to detect the levels of specific proteins in the cells.

The results showed that the presence of PM10 and diesel particles decreased levels of B-catenin, the protein responsible for hair growth. The study also revealed that the levels of three other proteins — cyclin D1, cyclin E and CDK2, which are responsible for hair growth and hair retention, were decreased by PM10-like dust and diesel particles in a “dose-dependent” manner.

Dr Hyuk Chul Kwon, who led the study at the Future Science Research Centre, said, “While the link between air pollution and serious diseases such as cancer and lung diseases is well established, there is little-to-no research on the effect of particulate matter exposure on the human skin and hair in particular. Our research explains the mode of action of air pollutants on HFDPCs, showing how the most common air pollutants lead to hair loss.”

Sources of PM include the burning of fossil fuels — petrol and diesel, as well as other solid fuels,and other industrial activities such as building, mining and the manufacturing of building materials like bricks.

“While it is difficult to escape from the surrounding pollution, limiting the time for walking in busy streets, especially during rush hour, should help reduce exposure,” said Dr Kwon. “If you are exercising outdoors, try to do so in areas that are less polluted and do not spend too much time waiting at traffic hot spots such as traffic lights.”

1.What did the new study find?

A.Air pollution can do great harm to our lungs.

B.The color of our skin can be influenced by air pollution.

C.Serious air pollution can probably prevent hair from growing.

D.Air pollution can affect hair growth by entering the bloodstream.

2.What is western blotting used to do?

A.To discover the protein helpful for hair growth.

B.To show the protein contents in the cells.

C.To compare different proteins in the cells.

D.To analyze the composition of hair cells.

3.What can we learn from Dr Hyuk Chul Kwon’s words?

A.His new research is superior to previous research.

B.The research he conducted is really of great importance.

C.The results of his new research need to be further improved.

D.A link between air pollution and diseases needs to be established.

4.What does Dr Kwon advise us to do?

A.To do as much exercise as possible.

B.To take action to reduce air pollution.

C.To avoid being exposed to air pollution.

D.To take public transport to avoid traffic jams.

Did you get a flu shot this year? For the first time, the Centers for Disease Control and Prevention in the US is recommending that all children ages 6 months through 18 years receive the flu vaccine.

Vaccines battle diseases caused by bacteria and viruses. A weakened form of the germ is introduced into the body. The body makes special substances called antibodies to fight the germs. If the actual germs were to attack, the antibodies would fight them.

Because there are many kinds of flu viruses, scientists must create a new vaccine formula (配方) each year. Researchers must make a prediction.

“The flu vaccine is not as effective as the polio (小儿麻痹症) vaccine or the measles(麻疹) vaccine,” says Dr. William Schaffner of Vanderbilt University School of Medicine.

“It’s not a great vaccine, but it is quite a good vaccine.”

But a flu vaccine doesn’t work for everyone. There are certain people who should be careful about taking it. Because the vaccine is produced from eggs, those who are allergic (过敏的) to eggs should not take it. If you have a fever, you should wait until you recover.

Some people are afraid that they might get the flu from the flu shot. Scientist say that it is not possible, because the viruses in the flu shot are inactivated (灭活的). But some minor side effects such as low-grade fever and body aches could occur. If they do, they begin soon after the shot and usually last only one to two days.

1.What is an antibody?

A. An antibody is a vaccine formula

B. An antibody is a germ that is introduced into the body

C. An antibody is a vaccine that fights diseases.

D. An antibody is a special substance to fight germs.

2.Which of the following statements is NOT true?

A. Not everyone is suitable for the flu vaccine.

B. The flu vaccine is not so effective as the measles vaccine

C. Flu viruses create new vaccine formulas each year.

D. People can’t take the flu vaccine at anytime.

3.It can be inferred from the text that _____.

A. scientists should change the vaccine formula each year

B. vaccines can battle diseases caused by bacteria and viruses

C. all children ages 6 months through 18 years can receive the flu vaccine

D. scientists are responsible for the side effects of the flu vaccine

4.Which of the following would be the best title for the text?

A. The flu vaccine        B. Side effects of the flu vaccine

C. How to prevent the flu  D. Not everyone can get the flu shot

When you first arrive in Oxford，it may take a little while for you to find your way around. The university is a large organization that is fully integrated into the city and has been evolving for 800 years. Some of the first things our students do when they arrive include finding a bike ( most students in Oxford find cycling is the best way to go around), setting up a bank account , getting their computer and mobile phone working , finding their department, getting to know their college and working out the best places to socialize.

One of the major events you will experience shortly after "coming up" to Oxford is matriculation. Matriculation is held at the University's Sheldonian Theatre and is the ceremony at which you are formally admitted to the university.

International students are invited to an orientation day at the start of the academic year. Sessions run throughout the day that will give you practical information about living and studying in UK and introduce you to other graduate students from all over the world who are starting their studies at Oxford at the same time as you , as well as to current Oxford graduate students and staff who will be able to help and advise you . The day covers topics such as studying and learning in the Oxford system, University services, information on living in Britain and culture differences, as well as addressing practical issues such as employment, immigration and visas, health and safety. You can choose which talks to attend and at the end of the day there is a social hour so you can meet fellow student.

Another good thing to experience early on is college dining.

A good first impression is important. So, how do you, when you’re meeting someone for the first time, make certain he or she doesn’t get the wrong image of you?

A study concluded that the first 30 seconds make or break the connection between two people when they meet for the first time. Another study conducted by UCLA found that “people evaluate one another by using the three V’s: visual (appearance), vocal (voice) and verbal (what you say).”

Before you head out on your next date to meet someone new, let’s concentrate on these areas:

●How others will see you. (Visual) Are you dressed well? Do you look like this date is important to you? Did you take some time with your appearance? Watch your manners: people don’t like bad manners.

●How others will hear you. (Vocal) Is your voice too soft? You might come across as insecure. If you speak softly, make an effort to speak clearly — don’t make your date have to work to hear you.

●What others will hear you say. (Verbal) People have a natural desire to connect — let them know you’re interested in what they have to say by repeating it back to them. Don’t say the same thing everyone else is saying.

1.What would be the best title for the text?

A. How to make friends with others

B. How to enjoy yourself in your life

［1］When children go to camp, they are on their own, sometimes for the very first time in their lives. They have to decide what to wear, what to eat and which activities to participate in. As a result they develop confidence and independence.

［2］As self-respect develops from learning to be on their own, children continue to try new activities. Also it is possible that they will engage in what they are unfamiliar with. In school, children do not experience success in the same way. Camp can be a school without failure because just having fun makes them a success.

［3］One of the greatest benefits of a camp experience is that children develop social skills. In a camp setting, a good counselor will make sure that every camper is included in the activity and that each child interacts with the others in a positive way. They learn to give and take, and they learn how to work and cooperate. Something as simple as clean-up, is not only there to get the cabin clean, but to promote a team atmosphere of working together which in turn results in friendship.

［4］The obvious benefit of camp is that campers make long lasting friendships. These friendships can often be unique and special because campers are living with each other and see the true personalities. Chi1dren learn to see others from a different viewpoint. Children tend to be accepted for who they are and do not have to be concerned about what they wear, what they are good at and how they look. This is because in a camp setting, respect and caring finally win out over materialistic objectives.

［5］In a word, camp does give children fun, friends and fulfillment.

The next time you need to get somewhere, you may be able to follow your nose. A study has found that a strong sense of smell is associated with a strong sense of direction.

Researchers conducted an experiment at McGill University in Canada. Fifty-seven adults were invited to participate in a virtual"way-finding task"in which they had to make their way around a virtual environment. They were given 20 minutes to learn about the virtual city. After having passed by each of eight landmarks at least twice, the participants were placed in front of one of the landmarks and asked to find the most direct route to one assigned by the researchers.

The participants also smelled 40 scented（有香气的）pens one at a time. After a brief sniff, the participants chose one word that best identified the smell from four words on a screen.

An additional exercise used a virtual maze（迷宫）to determine if the participants were more likely to rely on landmarks to find the way or if they used a more habit-based method built over time as people travelled the same route over and over again.

What the researchers found was that those with the ability to correctly identify the smells of the pens also had the easiest time performing the way-finding task by way of landmarks. A strong sense of smell was not identified in the participants who used the more habit-based method.

The connection between the sense of smell and way-finding likely came about as a result of the evolution of the nervous system. The original function of the sense of smell in humans may have been intended to support our spatial memory.

Keep that in mind the next time you get lost going to the dentist. It won't prevent you from getting horribly lost, but it's good food for thought along the way.

1.How did the researchers carry out the study?

A.By using typical landmarks in a real city.

B.By combining virtual tests with real-life tests.

C.By testing different senses in a virtual environment.

D.By collecting routine observation data from the participants.

2.What were the participants asked to do after they smelled a scented pen?

A.Decide whether they liked the smell.

B.Use a sentence to describe the smell.

C.Choose a suitable word for the smell.

D.Find the landmark that featured the smell.

3.Which of the following factors is better related to a strong sense of direction according to paragraph 5?

A.The way of using landmarks.

B.More experience in describing things.

C.Quick adjustment to the virtual world.

D.A more habit-based way-finding method.

4.The meaning of the word "spatial" underlined in Paragraph 6 relates to _____.

A.the situation B.the position

C.the spirit D.the time
