It’s normal for teens to want to stay connected with friends and social circle, but what about that happening in the middle of the night? The Journal of Youth Studies recently published new research showing that one in five teens from 12 to 15 regularly wake to spend all night on social media (社会媒体). Not surprisingly, the research also showed that these social night owls were three times more likely than others to feel tired at school and that girls were more likely than boys to be called to office.
The blue light produced by cell phones and computers makes the brain to stay awake, so it's easy to see why a teen might be up all night. A study in Psychological Science showed the same brain reaction: when teens saw large numbers of “likes” on their posts, they stayed awake with excitement as if they had eaten chocolates or won money. Besides not catching up on sleep and interrupting their sleep cycle, teens may never fully enter deep sleep that may be responsible for brain development and learning.
Considering about 72 percent of children from 6 to 17 sleep with some electronic media in their bedrooms, parents need to set rules sooner rather than later.
“Providing access (使用机会) to social media is a favor that children can earn and also lose,” Janie Feldman, an expert who treats sleep disorders (紊乱), reminds parents, “The bad effect is clear. So teens and parents should discuss and agree on its use, timing and access. When teenagers agree to the rules, it’s easier for parents to control how much time they use the phones or computers.”

Scientists say only enlarging the world’s nature reserve to help protect plants and animals may be useless. The main reason is that levels of human activity are rising in and around the nature reserves. In fact, recognizing spaces as protected areas is not reducing human activity there.
The researchers found that a lack of money to pay for land conservation (保护) is affecting conservation efforts. And it is a lack of communication between people who live in protected natural areas and outsiders. About 17 percent of the world is within protected areas, including the national parks, nature reserves and wilderness areas. Protected areas are important for supporting environments with many different kinds of plants and animals.
The researchers again found increasing human activity in most protected areas in every country. However, they said that human activity appeared to be more of a problem in nations with fewer roads and lower life standards on the Human Development Index (指数). The index uses information about life length, education and earnings to grade countries on human development.
Across the northern Australia, protected areas often proved effective at slowing human activity when compared with unprotected areas. But in South America, Southeast Asia and African countries, pressure from human activity inside protected areas was higher.
Experts say governments need to provide fund support to help protected areas. Simply recognizing a place as a protected area can’t be the beginning and the end of a conservation effort. Working with local people to take efforts is also important. If they’re not partners in the protected areas, then wildlife conservation is much more difficult.
1.What are protected areas mainly affected by according to the text?
A.Human activity. B.Climate change.

2.What’s the Human Development Index used to do?

3.What do experts advise governments to do for protected areas?
A.Enlarge protected areas.
B.Offer extra money and work with locals.
C.Attract more people to travel there.
D.Allow local people to farm there.
4.What can be the best title for the text?
A.People May Cause Harm to Plants and Animals
B.Local People Should Focus on the Natural Environment
C.Nature Reserves in the World Should Be Increased

For the first time since my open-heart operation, I have the energy to take my harp (竖琴) to the hospital rooms and play for anyone who likes it.
I checked in with two nurses and they gave me a list of rooms. The first man I played for was a patient who found it difficult to sleep. He smiled and with his eyes closed, he reached out to my harp. He was not interested in my voice, but he appreciated the harp. In the next room was a woman patient. I played some soft music for her and then she slept soundly.
Then I found a lovely elderly woman who was awake. There were flowers everywhere and photos of her and her husband at her bedside. She held my hand and talked for some time and was pleased to receive harp music. Playing for her was a special pleasure. She asked me how long I had been playing the harp, how much the harp weighed, how I learned it and why I wanted to learn it and so on.
We talked about books for a bit as well. I played until her grandson came in and he came back from overseas to see her. This woman was deeply loved—you could see that. She was beautiful and kind. I learn so much from these beautiful people who are brave to face their illnesses. It is always such a great honor to play for them.

More and more students are doing part-time jobs today. There are many advantage in students doing part-time jobs. Except earning some money to support themselves, they can learn stuff what cannot be learned from textbooks. We will learn to get along with different kinds of people, get useful working experience and to learn the value of labor.
Therefore, there are also some disadvantages. For example, too much work may take up much of the students’ study time and affected their studies. Another disadvantage is that money earned, if not proper used, may lead to some bad habits, or even greed.
Good or bad, it is not easy for students to getting part-time jobs in China now. To change the situation, people should develop fresh look at students doing part-time jobs and provide them with opportunities.
