Babies born in summer are more likely to become short-sighted in late life, a study has shown.
As many as a quarter of all cases of short-sightedness are caused by too great an exposure to sunlight in the first weeks of life, say eye experts.
They are advising all parents to put sunglasses on their babies during the first weeks.
Scientists had already established that over-exposure to sunlight caused shortsightedness in animals.
Researchers who compared the months in which babies were born with whether they needed glasses later on say the principle also applies to humans.
A study of almost 300,000 young adults-the largest of its kind-showed that those born in June and July had a 25 per cent greater chance of becoming severely short-sighted than those born in December or January.
Research leader Professor Michael Belkin, of Tel Aviv University, said it was because prolonged illumination(光照) causes the eyeball to lengthen-causing short-sightedness.
Hence the more light a newborn is exposed to, the more the eyeball lengthens and the worse the short-sightedness will be.
The mechanism which lengthens the eyeball is associated with levels of melatonin(褪黑激素), a pigment (色素) which protects the skin against harmful rays of the sun.
In young babies not enough melatonin is released as protection, meaning they are more vulnerable to sunburn and changes to eyeball shape.
Sight expert Professor Daniel O’Leary, of Anglia Ruskin University in Cambridge, said “At the moment we don’t know the precise cause of why light exposure affects sight, but the evidence seems to prove that it is one of the reasons for people becoming shortsighted.”
67. Babies born in summer are more likely to be shortsighted ____________.
A. because the summer sun is too strong for babies
B. because babies born in summer have lengthened eyeballs
C. if they are exposed to much sunlight in the first weeks after they are born
D. if parents don’t know a proper way to protect their babies’ eyes
68. Melatonin is a kind of material to ___________.
A. prevent the eyes from becoming near-sighted
B. protect the skin from harmful sun rays
C. make our body strong
D. protect babies’ eyes from summer sun
69.From what Professor Daniel O’Leary says we can conclude that ___________.
A. there is no evidence that shortsightedness is related to exposure to sunlight
B. whether light exposure affects sight still needs to be further proved
C. he believes that light exposure can cause shortsightedness
D. he tries to give the cause of why light exposure affects sight
70.The underlined word “vulnerable” in the passage probably means __________.
A. easy to be harmed B. resistant
C. protective D. changeable
“Just take a deep breath.” “Don’t think about it.” “You’re more likely to die in a car wreck on the way to the airport than you are in a plane crash.” These are just some words given to people with a fear of flying. But as Tom Cruise, playing Lt. Daniel Kaffee in the movie A Few Good Men, said, “I get sick when I fly because I’m afraid of crashing into a large mountain. I don’t think Daniel will help.”
But there’s a new application that just may. Today, the VALK Foundation, a Dutch group that’s a partnership between KLM Royal Dutch Airlines and the University of Leiden, launches the app in the US. The VALK Foundation was one of the first centers for research and fear-of-flying treatment in the world and is the organizer of three world conferences on fear of flying.
The foundation said the app, called Flight App VALK, is the first scientifically-developed, web-based treatment for people who suffer from mild to moderate fear of flying.
“The fear of flying application we have created aims to transfer all of the knowledge we have developed through our program into a mobile application that will help ease travelers’ fears,” said Dr. Lucas van Gerwen, director of the VALK Foundation. Dr. van Gerwen is also a psychologist and professional pilot with more than 30 years experience.
The foundation said up to 30% of adults are fearful fliers. The Flight App is designed to help relax passengers before and during flights by educating users about flight safety and turbulence. It explains the sounds and sensations they can expect during departure, flight and landing. And, if a passenger’s flight stress reaches a panic level, they press a special panic button which provides audio and written information to help decrease stress levels. Most importantly, the Flight App can be used during the flight in the airplane mode. Once downloaded, the program does not require Internet connection in the air.By saying the words at the beginning of the passage, people are expected to ______.
A.decrease their fear of flying |
B.get rid of their doubt about plane |
C.have a good time on their flight journey |
D.use some medicine to cure their fear of flying |
Flight App VALK is aimed to ______.
A.help passengers experience the fear of flying |
B.help relax passengers before and during flights |
C.treat people who suffer from mild fear of flying |
D.teach people the basic knowledge of taking flight |
According to the passage, the VALK Foundation ______.
A.is a group focusing on psychology on the flight |
B.was the first center to do research into fear of flying |
C.organize the world conferences on fear of flying annually |
D.focuses on researching and offering treatment on fear of flying |
What does the last paragraph mainly tell us?
A.Many adults are suffering from fear of flying |
B.It’s convenient for people to use the Flight App |
C.Many planes will be installed with the Flight App. |
D.The Flight App can decrease stress levels effectively |
In which column of a newspaper can we read this passage?
A.Culture | B.Entertainment | C.Technology | D.Education |
Folklore is the branch of the study of man which deals with local customs, tales and traditions. Everybody is a storehouse of folklore, though not everybody realizes it. Often, in deed, those who have never heard the word folklore have the greatest store of it, for the people with least book education commonly cherish most firmly old ideas and superstitions (迷信) which have been passed on by word of mouth for generations. Everyone has heard stories of ghosts, witches, fairies, and giants. We all know some proverbs and have come across such ideas as, for example, that it is lucky to see black cat and unlucky to see a single magpie (喜鹊). We keep certain seasons of the year as festivals, such as Christmas, and we are familiar with the special customs connected with weddings and funerals. All such things are of interest to those who study folklore.
People who study folklore won’t criticize the old beliefs and practices they come across as silly, childish, or old-fashioned. Instead, they will try to collect accurate records of them and then see how these are connected with other ideas and customs of other places or times. By comparing with what is known of olden times or the folklore of other countries, they try to discover how certain beliefs and practices came into being, and what purpose they serve now or used to serve in the past.
Often we find that the beliefs which seem most peculiar and unreasonable, and the customs which appear least practical, are of the greatest interest and importance because they are commonly the oldest. Sometimes they were part of an ancient ritual (惯例) or served a useful purpose when people’s way of life was different from what it is now. So we not only learn about what people thought and did in the past but are better able to understand present customs. People often keep up customs when they have forgotten the original reason for them, and in the course of time a fresh reason gets attached to the custom. Thus, when some joker ties an old shoe to the back of the taxi taking the bride and bridegroom to the station for their honeymoon, he would say it was “for luck”, but actually a shoe is an old fertility (繁殖力) symbol and has a place in the wedding customs of China and Palestine.The underlined word “they” (in Para.2) most probably refers to _________.
A.practices and beliefs | B.customs and traditions |
C.records and tales | D.places or times |
It is most unlikely for people who study folklore to _________.
A.collect as many records of old beliefs and practices as possible |
B.compare the present customs with those of the olden times |
C.criticize the old beliefs and superstitions as silly or childish |
D.find out the purpose the certain beliefs and practices serve or used to serve |
Which of the following statements is true about customs?
A.The customs which do not appear practical mean nothing to most people. |
B.The reasons for certain customs may change in the course of history. |
C.People who practice customs are quite familiar with their origins. |
D.The wedding customs in China and Palestine are of great similarity. |
What would be the best title for the passage?
A.What Does Folklore Really Mean? |
B.How Do People Keep Up Customs? |
C.Who Studies Tales And Traditions? |
D.When Did Some Old Beliefs Begin? |
Recently I spoke to some of my students about what they wanted to do after they graduated, and what kind of job prospects they thought they had.
Given that I teach students who are training to be doctors, I was surprised to find that most thought that they would not be able to get the jobs they wanted without “outside help”. “What kind of help is that?” I asked, expecting them to tell me that they would need a relative or family friend to help them out.
“Surgery(外科手术)”, one replied. I was pretty alarmed by that response. It seems that the graduates of today are increasingly willing to go under the knife to get ahead of others when it comes to getting a job. One girl told me that she was considering surgery to increase her height.“They break your legs, put in special extending screws, and slowly expand the gap between the two ends of the bone as it regrows, you can get at least 5cm taller!”
At that point, I was shocked. I am short, I can’t deny that, but I don’t think I would put myself through months of agony(痛苦) just to be a few centimeters taller. I don’t even bother to wear shoes with thick soles, as I’m not trying to hide the fact that I am just not tall! It seems to me that there is a trend toward wanting “perfection”, and that is an ideal that just does not exist in reality.
No one is born perfect, yet magazines, TV shows and movies present images of thin, tall, beautiful people as being the norm. Advertisements for slimming aids, beauty treatments and cosmetic surgery clinics fill the pages of newspapers, further creating an idea that “perfection” is a requirement, and that it must be purchased, no matter what the cost. In my opinion, skills, rather than appearance, should determine how successful a person is in his chosen career.We can know from the passage that the author works as ______.
A.a doctor | B.a model | C.a teacher | D.a reporter |

D.it is one’s appearance instead of skills that really matters in one’s career |
What does the author think of his height?

We use both words and body language to express our thoughts and opinions and to communicate with other people. We can learn about what a person is thinking by watching his or her body language. Words are important, but the way a person stands, folds his or her arms, or moves his or her hands can also give us information about his or her feelings.
Just like spoken language, body language varies from culture to culture. Making eye contact —looking directly into someone’s eyes — is in some countries a way to show interest. In other countries, however, eye contact is rude or disrespectful. The gesture for Ok, making a circle with one’s thumb and index finger, has different meanings in different cultures. In Japan, someone who sees another person making the gesture will think it means money. In France, a person seeing the same gesture will think it means zero. In Brazil and Germany, however, the gesture is rude. The thumbs-up gesture, meaning “great” or “good job” in the US is rude in Nigeria, but in Germany and Japan it means the number one. The “crazy” gesture, moving the index finger in a circle in front of the ear, means “you have a phone call” in Brazil.
Even the gesture we use for “yes” and “no” are different around the world. In many countries, shaking one’s head means “no”, and nodding means “yes”. In Bulgaria, parts of Greece, and Iran, however, the gestures have the opposite meaning. There are also differences as to how often we touch each other, how close we stand to someone we are talking to, and how we act when we meet or part. In some countries, for example, France and Russia, a visiting friend is greeted with a kiss on the check, in other countries people greet each other with a firm handshake, a loving hug, a bow or a simply a nod of the head.
While there are many different interpretations of our body language, some gestures seem to be universal. Pressing one’s palms together and resting one’s head on the back of one’s hand while closing the eyes as if sleeping means “I am tired.” A good way of saying “I am full” is moving the hand in circles over the stomach after a meal. If a person pats his or her stomach before a meal, it usually means “ I’m hungry.”
Perhaps the best example of universally understood body language is the smile. A smile can help us get through difficult situation and find friends in a world of strangers. A smile can open doors and tear down walls. It can be used to express almost any emotion. We can use a smile to apologise, to greet someone, to ask for help or to start a conversation. We can smile at ourselves in the mirror to make ourselves feel happier and stronger. And if we are feeling down or lonely, there is nothing better than to see the smiling face of a good friend.In our daily life, which of the following do we use to communicate with each other?
A.gestures | B.words | C.smiles | D.all above |
As a Chinese , if you are lost in Germany, without knowing German, you’d better---- to ask for help?
A.use eye-contact | B.thumb-up |

A.wide | B.common | C.not similar | D.in space |
When something goes wrong,it can be very satisfying to say, “Well, it’s so-and-so’s fault.” or “I know I’m late,but it’s not my fault; the car broke down.” It is probably not your fault,but once you form the habit of blaming somebody or something else for a bad situation,you are a loser. You have no power and could do nothing that helps change the situation. However, you can have great power over what happens to you if you stop focusing on whom to blame and start focusing on how to remedy the situation. This is the winner’s key to success.
Winners are great at overcoming problems. For example, if you were late because your car broke down, maybe you need to have your car examined more regularly. Or, you might start to carry along with you the useful phone numbers, so you could call for help when in need. For another example, if your colleague (同事) causes you problems on the job for lack of responsibility or ability, find ways of dealing with his irresponsibility or inability rather than simply blame the person. Ask to work with a different person, or don’t rely on this person. You should accept that the person is not reliable and find creative ways to work successfully regardless of how your colleague fails to do his job well.
This is what being a winner is all about—creatively using your skills and talents so that you are successful no matter what happens. Winners don’t have fewer problems in their lives; they have just as many difficult situations to face as anybody else. They are just better at seeing those problems as challenges and opportunities to develop their own talents. So, stop focusing on “whose fault it is.” Once you are confident about your power over bad situations, problems are just stepping stones for success.According to the passage,winners______.
A.deal with problems rather than blame others |
B.meet with fewer difficulties in their lives |
C.have responsible and able colleagues |
D.blame themselves rather than others |
