More and more people are taking their iPads to bed with them to surf the web, check facebook or send e-mails before switching off the light. But researchers are warning that the blue light their screens give off can stop users getting a good night’s sleep. That is because this type of light is similar to daylight, convincing the brain that it is still daytime. Blue light prevents the production of a brain chemical called melatonin, which helps us fall asleep. By contrast, light which is more orange or red does not prevent melatonin production, perhaps because our brains recognize it as a cue that the day ends.
Scientists have known for years that staring at screens late in the evening can affect sleep ---- they are television screens, computer screens or mobile phone screens. However, because mobiles and iPads are by nature portable ---- not to say addictive ---- more people are taking them into the bedroom. Users also tend to hold them much closer to their eyes than a computer or television screen.
Researchers are warning that looking at iPad displays for more than two hours leads to lower natural melatonin levels as the devices give off blue light. They say, “Turning off the devices at night is the final solution. But if you have to use these devices at night, dim the display to cut down irritation of the eyes and limit the time you spend on them before bed.”
They wrote in the journal Applied Ergonomics(应用人类工程学) that iPad makers should adjust the spectral power distribution(光谱功率分布) of the devices so that they affect the sleep patterns of users less.
It is not just a good night’s sleep that could be harmed by too much late night screen time. Researchers know that long-term harm to sleep patterns can lead to an increased risk of obesity and even cancers.
1.Blue light prevents iPad users from sleeping well because ____.
A. it is the same as daylight which keeps people awake
B. it makes the brain more active
C. it is brighter than light that is more orange or red
D. it can help decrease the production of melatonin
2.The underlined phrase “dim the display” means ____.
A. keep away from the display
B. make the display less bright
C. clean the display carefully
D. turn off the display
3. In the last paragraph, the author intends to ____.
A. warn of the seriousness of long-term poor sleep
B. call on researchers to study sleep patterns
C. show the danger of obesity and cancers
D. show how sleep is harmed by using iPads too much
4.What’s the main idea of the passage?
A. Scientists are warning that blue light is bad for our health.
B. People should limit the use of electronic devices
C. Using iPads before bed can cause a poor night’s sleep.
D. Looking at screens of iPads increase chances of sleeplessness.

Almost two-thirds of children want their parents to spend more time reading to them before bed, and most prefer Mum’s storytelling to Dad’s, researchers said.
They carried out a study that showed younger children aged 3-4 were most hungry for more stories, with over three-quarters saying they wished their parents read to them more often.
More than half of all children aged 3-8 said story time was their favourite pastime with their parents.
"The results of our research confirm the traditional activity of storytelling continues to be a powerful learning and emotional resource in children's lives," said child psychologist Richard Woolfson.
Storytelling ranked higher than television or video games among pastimes for kids, and 82 percent said reading a story with their parents helped them sleep better, according the survey of 500 children aged 3-8 in Britain.
The best storytellers were mothers who used funny voices to illustrate different characters or made their own special sound effects to keep the story moving, researchers said.
When mum and dad are not at hand, celebrities(名人) will do: over 30 percent of children said they would like to hear a bedtime story from Harry Potter star Daniel Radcliffe, with teen idols(偶像) Zac Efron, Miley Cyrus and Emma Watson.
"It can be very difficult for parents to find the time to read with their children, but these moments can help build strong relations and play a vital part in their child's development," said Woolfson.
1.The underlined word “pastime” in the passage most probably means ________.
A.old time B.entertainment C.emotion D.character
2.The author develops the passage mainly by ________.
A.pointing out similarities and differences B.following the natural time order
C.comparing opinions from different fields D.providing examples and statistics
3.Reading a story with their parents helped most kids aged 3-8 ________.

With these increased pressures and difficulty in ensuring a graduate job, more people are turning to recruitment(招聘) agencies for help. Luke Harper wrote for the Independent warning students to be cautious when using graduate recruitment agencies in their job hunt. The article’s main argument against graduate recruitment agencies is that they are looking to sign people up to the agency and harvest data, without having any real intention to personally find them a job.
The fundamental problem with this approach is a basic misunderstanding of how the recruitment part works. One of the more common ways is that recruitment agencies aim to find you a job to secure a fee from their clients(客户). Recruitment agencies operate as a business, not a careers service and are not expected to find you a job while you wait around.
There is no denying that among the recruitment agencies, there are some CV(简历) hungry, cut and shut agencies that are uninterested in the candidates they have on their books. However, nowadays these are in the minority and don’t tend to last very long.
Paul Farrer, Chief Executive of a leading recruitment agency is worried that a few bad apples are ruining the reputation of what is an excellent part. Farrer said “The trouble with such an imbalanced and misleading article is that some graduates may now be put off approaching recruitment agencies who may well be able to help them.”
Professionals in the industry are cautious of how some of the less respectable agencies operate. Earnest(认真的) recruiters believe that graduates should be aware that some of these agencies will take on graduates for all their details rather than helping them find a job, like Harper mentioned. To fight this, Farrar advises that “Graduates should have a simple checklist before approaching any agency. Has the agency taken the time to talk to me? Have they invited me to a face-to-face meeting? Have they guaranteed not to forward my CV to any employer without my permission? These three steps will safeguard every application.”
Farrer also pointed out that that is not the only safety net that graduates can rely on. He said “Graduates can also check to see if the agencies are members of either APSC or the REC, the two trade bodies they can make an official complaint to. The vast majority of recruitment agencies are professional organizations that help place thousands of graduates every year and poorly researched articles help no one.”
1.The main purpose of this passage is _______________ graduate recruitment agencies.
A. to advise readers to be cautious of
B. to argue against some misjudgment against
C. to explain why there is a prejudice against
D. to seek the solutions to the problems caused by
2.Which of the following is right according to the passage?
A. Luke Harper holds the same idea about jobs with Paul Farrer.
B. Recruitment agencies actually do the same work as a careers service.
C. Job hunters’ detailed information is of value to recruitment agencies.
D. A member of APSC or the REC will not cheat its clients.
3.What advice does Paul Farrer give graduates to avoid less respectable agencies?
A. Consulting professionals before giving their personal details to an agency.
B. Making a face-to-face investigation into an agency before approaching it.
C. Guaranteeing that the agency will not forward their CV to any employer.
D. Selecting some agencies that are monitored by official trade bodies.
4.What is the author’s attitude towards graduate recruitment agencies?
A. Neutral. B. Positive.
C. Negative. D. Not Clear.

Kids are loveable. With them around, our lives are brighter and more fun. Also our kids change the atmosphere of our house. When they’re in the house, it appears that every negative thing seems to disappear, and brighter moments start to appear. If they aren’t around, our life seems dull and boring, which is why we miss them when they’re gone. Yes, kids can change our lives but the question is: what can we offer them in return? As parents, it is our duty and our responsibility to provide our kids with what they need.
Then what are the basic needs of our kids? Firstly, it’s important to give kids the right foods and nutrition they need. Keep in mind that these foods aren’t just those foods found in stores and other fast food restaurants. Instead, our kids need foods that are rich in nutrients.
Secondly, it’s our duty to make sure our kids are safe all the time. We can give our family a good and simple house depending on our money but the important thing is that they feel secure. Our kids will appreciate it very much if we give them their play room or bedroom.
The third basic need is clothing, which protects them from harsh weather conditions. They could die from coldness or heat if we don’t consider proper clothing. Education is also one of the important basic needs of our kids, because there is a need for them to know the things around them.
However, It isn’t enough to spend all your time working to provide whatever your family need and want, because then you’ll lose time for the family. Just remember to give love and attention to your family no matter how busy you are. Every effort is surely appreciated and loved.
