3 . Last night, I found my mother sit with her legs crossed on the sofa, looking through her iPhone with her glasses. This is not the first time I have caught her like this. My father once tapped (敲) away on his phone with a serious look on his face, saying the “I’ll be with you shortly” line. I have learned by now that this is to tell me to leave him alone for the next 10 minutes. Although they don’t like admitting it, both of my parents                    couldn’t go without their phones as I do.

Growing up, we are repeatedly reminded that we are those who prefer to text our friends in the same room rather than make eye contact with them. We are ruining the English language because we like using heart-eyes emojis (表情符号) instead of spelling it out. And even though I can recognize myself as a social media (媒体) addict, I think parents should at least consider that not only the young generation (代), but also they like phones.

I get upset when I receive the “I’ll be with you shortly” line from a parent. But, at the same time, leaving the room to wait until my father is finished with his “serious business” has now become the norm.

Whether you want to escape your noisy children for a while, or want to stay up late tapping through Twitter, all of these are common. But you should fully understand it. We—your children—know how addictive it can be and how difficult it is to turn it off. So before calling us out and telling us to “put our phones away at the table” or even worse, saying how damaging social media can be to us, maybe you should lead by example and consider how much time you spend on the phone as well as how this is influencing your children and your relationship with them. Maybe in this way we can work on our addiction together.

4 . Hundreds of children are being treated for sleep problems in Wales every year. In some cases，babies，infants (婴儿)and teenagers have been admitted to hospital in north Wales alone.

The Children’s Sleep Charity said many children were suffering from lack of sleep mainly because of technology use. Public Health Wales said sleep was as important to a child’s health as healthy eating and exercise，and children with poor sleep patterns were more likely to be fat.

Statistics obtained (获得) under the Freedom of Information Act by BBC Wales found at least 408 children have been admitted to hospitals across Wales suffering from sleep disorders since March 2013.

Children aged between 0 and 4 made up the highest number of inpatients (住院病人)，with some newborns being treated for sleep-related problems from the day of birth.

Vicki Dawson，who set up the Children’s Sleep Charity (CSC)，said sleepless nights were putting both children and parents in anxiety. “Their weight and growth may also be affected as well as their mental health，”she said.

Teachers said children showing signs of sleep shortage and tiredness in class were a concern as they couldn’t concentrate for long periods.

Psychologist Amy McClelland，of Sleep Wales，saida common problem was that children were “over excited”before bed and that families should get back to basics. “Think 1950s family home. Dinner as a family，read，chat，a film maybe，lights off and then bed. ”She added.

Nowadays, it is common that more and more high school students open their own micro- blogs on the Internet. For one thing, it can provide a colorful platform to show their talent. For    1    , it is a useful way to release their     2     （press）. And all these make it more and more popular with high school students.    3     many parents and teachers hold a different view. They think that managing a microblog will take a lot of time and energy,    4    should be used to study.

I am greatly in favor     5    this activity. Today the Internet     6    (play) an important role in our life. Therefore, as high school students of the Information Age, we need to learn to make use of this     7     (mean) tool to communicate and display ourselves. What’s more, opening and organizing microblogs need various abilities such as writing, designing, being good at computer skills and so on. Only if we master those abilities can we make a successful microblog. As a result, we improve ourselves while     8     (organize) our microblogs.

In fact, the microblog     9     (oneself) is of little harm. It is your attitude towards it    10    matters. We should take the advantage of it and avoid some bad effects.

6 . It has long been believed that the smart phones in our pockets are actually making us duller； but now there is evidence for it.

Researchers at the University of Texas discovered that people are worse at conducting tasks and remembering information if they have a smart phone within eye shot. In two experiments they found phones sitting on a desk or even in a pocket or handbag would distract users and lead to worse test scores even when it was set up not to disturb test subjects. The effect was measurable even when the phones were switched off, and was worse for those who were more dependent on their mobiles.

The researchers tested 520 university students on their memory and intelligence when in the presence of a smart phone to see how it affected them. Participants were told to complete tests in mathematics, memory and reasoning with their smart phones either on their desk, in their bag or pockets，or in another room. Those who had their phones on the desk recorded a 10 per cent lower score than those who left them in a different room on operational tasks, which measures working memory and focus. Those who kept their phones further out of sight in their pockets or their bags scored only slightly better than when phones were placed on desks.

The researchers found that the negative effect of having a phone within eye shot was much greater among those who said they were dependent on their smart phones. Participants who had expressed sympathy with phrases such as “I would have trouble getting through a normal day without my cellphone” and “using my cellphone makes me feel happy” performed as well as others when their phone was in a different room，but worse when it was placed on their desk.

The researchers said the effect arises because part of a smart phone users’ mind is devoted to trying not to think about distractions such as whether they have any messages when the smart phone is in their sight.

When Li Ming was a primary school student,he had to wearing glasses.Now he is becoming more and more near-sighted.The more he reads,the thick his glasses become.As far as I know it,more and more students have poor eyesight in China.

Why did so many students have to wear glasses?Sometimes they read in strong sunlight and sometimes they read in places which the light is too poor.Some watch TV too many.Some even have a bad habit of reading in bed.As result,their eyesight becomes poorer and poorer.

I think students should know the importance of protecting their eye.They should read in places with enough light.Look out of the window or just go out before reading for a while.In a word,we should relax our eyes as often as possibly.

8 . The Indian government may use 3D paintings as virtual speed breakers（减速带） on major highways and roads, in order to check speeding and careless driving, and finally make its deadly roads a little safer. "We are trying out 3D paintings used as virtual speed breakers to avoid unnecessary requirements of speed breakers," India's transport minister Nitin Gadkari wrote.

The optical illusions(视觉错觉) are supposed to encourage drivers to slow down automatically. Earlier, India had ordered the removal of all speed breakers from highways, which are considered to be a safety hazard for high-speed vehicles. India has the highest number of road accident deaths in the world. According to the World Health Organisation, over 200,000 people are killed by road accidents.

The use of optical illusions as speed breakers was first pioneered in the American city of Philadelphia in 2008, as part of a campaign against speeding motorists. The technique has also been tried out in China to create floating 3D crossings. In India, cities such as Ahmedabad and Chennai have already experimented with 3D zebra crossings in the last one year. In Ahmedabad for instance, a mother and her daughter, both artists, have painted 3D crosswalks in the first few months of 2016. The artists say their motto is "to increase the attention of drivers", and that the concept has been successfully tested in accident-prone zones on a highway.

However, critics argue that once drivers know that these speed breakers are visual illusions, they may ignore them. Others also point out that India's decision does not consider the safety of a large number of pedestrians. In the end, the new policy may be just one step towards improving road safety.

Jimmy is one of my closely friends. Two months ago, his mother bought a computer to him as a birthday present. She hoped Jim will study hard with the help of the computer. To his surprise, Jimmy just wasted plenty of time play computer games every day. Now she regrets buying the computer. As matter of fact, a computer can do a lot of everyday jobs for us. It is wide used in factories, hospitals, banks and so on. Many computers scientists are now trying to make the computer to “think” like a man. In my opinion, the key is what we should use it wisely.
