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

Babies are born yogis. Once we were all able to pull our toes up by our ears and laugh about it. Then we aged, got injured, and began carrying stress in our shoulders and back. In short, we lost our balance.
Yoga(瑜伽) is an ancient practice that helps create a sense of union in body, mind, and spirit. It brings us balance. I was seriously out of balance when I started practicing yoga in 1999. I had plantar facilities in both feet, and my doctor had warned me against all the things I loved to do: walking, hiking, and playing tennis. I was desperate for exercise. Yoga became my salvation and even enhanced my other fitness activities. I practice yoga at least twice a week, but I consider yoga to be part of my daily life because after a while you no longer just practice yoga—you love it.
Yoga becomes part of your physical life. Your body grows stronger, more toned, and more flexible as you move from one pose to the other. I spent a week in Mexico at a yoga retreat, and it was the first vacation on which I lost weight. “Rather than building muscle, yoga builds muscle tone,” says Shakta Kaur Khalsa, author of the K.I.S.S. Guide to Yoga. “Because yoga helps maintain a balanced metabolism (新陈代谢), it also helps to regulate weight. Additionally, yoga stretches muscles lengthwise, causing fat to be removed around the cells.” I do yoga poses throughout the day. After hours at my computer, I stretch my stiff shoulders and arms. When I need a boost of energy, I do energizing poses. When I am feeling exhausted at the end of the day, I do restorative poses.
Yoga becomes part of your mental life. Yoga teaches you to focus on breathing while you hold the poses. This attention to breath is calming; it dissolves stress and anxiety. I use yogic breathing on the tennis courts, in the dentist’s chair, and in traffic jams. You should always leave a yoga practice feeling energized, not tired. If you feel tired after yoga, it means you spent the time “fighting” yourself, trying to force yourself into poses. In yoga, you “surrender” to the pose by letting go of the tension.
Yoga becomes part of your spiritual life. Yoga is practiced by people from all religions; it is not restricted to any religious group. Yoga teaches “right” living in how we deal with ourselves and others. As I work on a difficult pose, I learn patience, forgiveness, and the value of gentleness. Yoga advocates proper eating, but you don’t have to be a vegetarian to practice yoga.
1.What would be the best title for this passage?

Whether in the home or the workplace, social robots are going to become a lot more common in the next few years. Social robots are about to bring technology to the everyday world in a more humanized way, said Cynthia Breazeal, chief scientist at the robot company Jibo.
While household robots today do the normal housework, social robots will be much more like companions than mere tools. For example, these robots will be able to distinguish when someone is happy or sad. This allows them to respond more appropriately to the user.
The Jibo robot, arranged to ship later this year, is designed to be a personalized assistant. You can talk to the robot, ask it questions, and make requests for it to perform different tasks. The robot doesn’t just deliver general answers to questions; it responds based on what it learns about each individual in the household. It can do things such as reminding an elderly family member to take medicine or taking family photos.
Social robots are not just finding their way into the home. They have potential applications in everything from education to health care and are already finding their way into some of these spaces.
Fellow Robots is one company bringing social robots to the market. The company’s "Oshbot" robot is built to assist customers in a store, which can help the customers find items and help guide them to the product’s location in the store. It can also speak different languages and make recommendations for different items based on what the customer is shopping for.
The more interaction the robot has with humans, the more it learns. But Oshbot, like other social robots, is not intended to replace workers, but to work alongside other employees. "We have technologies to train social robots to do things not for us, but with us," said Breazeal.
1.How are social robots different from household robots?
A. They can control their emotions.
B. They are more like humans.
C. They do the normal housework.
D. They respond to users more slowly.
2.What can a Jibo robot do according to Paragraph 3?
A. Communicate with you and perform operations.
B. Answer your questions and make requests.
C. Take your family pictures and deliver milk.
D. Obey your orders and remind you to take pills.
3.What can Oshbot work as?
A. A language teacher. B. A tour guide.
C. A shop assistant. D. A private nurse.
4.We can learn from the last paragraph that social robots will _______.
A. train employees B. be our workmates
C. improve technologies D. take the place of workers
5.What does the passage mainly present?
A. A new design idea of household robots.
B. Marketing strategies for social robots.
C. Information on household robots.
D. An introduction to social robots.

One in five women and one in eight men are becoming more tired and less productive, according to a new Australian study on mobile phone use.
Led by the Queensland University of Technology in Australia, researchers surveyed 709 mobile phone users across the country aged 18 to 83 and asked them a series of questions based on a similar study 13 years ago. Identifying a phenomenon "technoference (科技干扰)", researchers discovered a significant increase in people blaming their devices for losing sleep, becoming less productive and even getting more aches and pains".
According to the study's lead author Dr Oscar, the issue is so bad that 24 percent of women and 15 percent of men are now considered to be " problematic mobile phone users". "When we talk about technoference, we're referring to the everyday intrusions (侵入)and interruptions that people experience due to mobile phones and their usage," he said. "Our survey found technoference had increased among men and women. For example, self-reports relating to the loss of sleep and productivity showed that these negative outcomes had significantly increased during the last 13 years. This finding suggests that mobile phones are potentially increasingly affecting aspects of daytime functioning due to lack of sleep. "
Compared to a 2005 study, "technoference" issues for 18 to 24-year-old experienced a surprising 40. 9 percent rise, while those aged 25 to 29 also recorded a dramatic increase of 23. 5 percent.
Oscar said that with the number of smartphone users around the world expected to surpass 2. 5 billion before the end of this year, the problem of "technoference" could get even worse. "The speed and depth of smartphone take-up makes our population particularly vulnerable to some of the negative consequences of high mobile phone use." he said. "Rapid technological innovations have led to dramatic changes in today's mobile phone technology, which can improve the quality of life for phone users but also result in some negative outcomes. "
1.How are people affected by technoference according to the text?
A.It makes people addicted to communicating online.
B.It pushes people to work at a fast pace.
C.It causes people to sleep less at night.
D.It brings negative outcomes to people of all ages.
2.Which group are most influenced by smartphones?
A.Young women. B.Young man
C.Children. D.Seniors.
3.What does the underlined word "vulnerable" in paragraph 5 probably mean?
A.Widely spread. B.Easily hurt.
C.Deeply devoted D.Absolutely accustomed.
4.What does the text mainly talk about?
A.The increasing side effects of smartphones.
B.Ways to solve technoference problem.
C.Smartphones and people's happiness.
D.The popularity of smartphones.
