1 . 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.”

A．Girls often called to office.

B．Teens who stay up late on social media.

3 . Three boys were enjoying themselves in their hometown of Bovina, Mississippi. However, their lives were turned upside down when they discovered the jawbone of a Mastodon (齿乳象).

Brothers Shawn and Caid Sellers and cousin Michael Mahalitc found the prehistoric bone in a piece of earth that was recently plowed (犁、耕). “I thought it was a log,” Caid said. “I tried to pick it up and it was really heavy and I saw teeth on it.” The bone weighed about 50 pounds. They eventually got the bone to their home and fitted it in their tub (浴盆), but it took their collective strength, might and a golf cart, to carry the large Mastodon bone.

“They didn’t expect to find that,” Michael’s mom said. “Now that they have, I believe that they will be more aware of their surroundings and what they’re digging up when they are digging and playing.”

“We’ve gotten a lot of petrified (石化的) wood and Civil War relics from the area and that’s what I thought it was,” the brothers’ mother said. “This is our first set of teeth we’ve found. So we thought it was their imagination. We were quite surprised to see that it was not their imagination.”

They were exploring near the brothers’ home. Lo and behold (真想不到), they saw what they thought resembled a fossil. It was the curator of paleontology (古生物负责人) of the Mississippi Museum of Natural Science, George Phillips, who first identified the bone as a “very mature individual.”

The Mastodon was a mammal who lived during the prehistoric times. They had long tusks and trunks, like elephants. They were clearly different from their modern-day counterparts, as well as woolly mammoths (猛犸).

1. How did they find the jawbone of a Mastodon?

A．With great efforts.	B．By chance.
C．Instructed by an expert.	D．Through imagination.

2. At first the brothers’ mother thought the jawbone was________.

A．from people who died in the Civil War	B．the bone from a very mature individual
C．like a log or something	D．the prehistoric bone

3. The discovery of the jawbone of a Mastodon is important mainly because it________.

A．helps people to know more about the Civil War

B．teaches kids to be more aware of their surroundings

C．promotes the research on more prehistoric creatures

D．attracts the Mississippi Museum of Natural Science

4. Which of the following can be the best title for the article?

A．Prehistoric Bones Recently Found in Mississippi

B．Not Petrified Wood Nor Civil War Relics

C．First Identifying Bone as a “Very Mature Individual”

D．Unexpectedly Discovering Mastodon Jawbone

4 . When I was in the fifth grade and Mr. Gardner asked a question, my hand would often shoot up in enthusiasm. After giving me a few opportunities, he would try to give other students a chance. My hand, though, would remain in the air, and after some time, I’d start waving it around. Then, there was the time I entered drumming classes. But all we were allowed to do in the first class was practice one beat over and over again. I never went back.

I would have done terribly in the Stanford Marshmallow (果浆软糖) Experiment. In this classic study, researchers gave children a choice between one marshmallow right away and two later. The results showed that those who could wait 15 minutes ended up scoring 210 points higher on the SAT, an examination that American high school students take before they go to college.

So clearly, delaying(延迟的) gratification or bearing up under pain have their benefits. It needs patience, which keeps us from being stuck to ideas formed previously, and helps us let go of our strong desire for consequences. We come to accept that we don’t always or immediately know what is best, and learn to recognize that our reality is in constant changes. Patience improves our understanding of deeper truths and helps us expand our views.

The journey of patience is rooted in knowing that our present reality will finally give way to changes. But changes won’t always happen when we think they should, and patience with ourselves comes from accepting that there are things we can control and things we can’t. And though we must make great efforts to keep pushing the boundaries of our awareness and to improve our ability to rest in comfort in the present moment, how fast we develop isn’t up to us.

That same fifth grader who couldn’t wait to speak out answers now sees the value of meeting questions with a heart of patience.

7 . 根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。While it is impossible to live completely free of stress, it is possible to prevent stress as well as reduce its effect when it can’t be avoided. The US Department of Health and Human Services offers the following suggestions for ways to deal with stress.·Try physical activity.When you are nervous, angry or upset, try releasing (释放) the pressure through exercise or physical activity.    1    ·Take care of yourself.You should make every effort to eat well and get enough rest. If you easily get angry and cannot sleep well enough, or if you’re not eating properly, it will be more likely that you will fall into situations of stress.    2    ·Make time for yourself.    3    Don’t forget, play can be just as important as work. You need a break from your daily routine to just relax and have fun. Go window-shopping or work on a hobby. Allow yourself at least a half hour each day to do something you enjoy.·    4    Stress can result from disorganization (杂乱无章) and a feeling that “there’s so much to do ,and not enough time.” Trying to take care of everything at once can be too much for you and, as a result , you may not achieve anything. Instead, make a list of everything you have to do, then do one thing at a time.    5    Set out to do the most important tasks first.

A．Bear in mind the most important task.

B．Schedule time for both work and play.

C．Check off each task as it is completed.

D．Make a list of the things you need to do.

E．For example, you could take your job as your hobby.

F．If stress repeatedly keeps you from sleeping, you should consult a doctor.

G．Running, walking, or playing tennis are just some of the activities you might try.

8 . Beneath our feet_____ that our lives depend on for food and clothing.

9 . Shackleton kept his promise ____he would return to Elephant Island ____the crew had been left.

10 . If you feel at present that you don’t have enough friends in your life, one reason may be that you have let yourself become too busy to make time for the relationships you already have. Starting and keeping friendship require effort and commitment (责任、义务、承诺).

Many of us let our lives become so busy with work and other commitments that we don’t get around to scheduling time for pleasure and renewal (叙旧) with the friends, relatives and acquaintances we already have.

Making the effort to call your friends more regularly and to accept more of the invitations you receive from others can improve your social life in a hurry!

Are there any people you could call right now and be assured of a pleasant welcome? Are there people that you could depend on to help you in time of difficulty? Can you have close talks with them? Do you have fun when you are together? Are you happy to have them in your life?

If you haven’t seen much of them lately, is it because you have become too busy? Have you grown apart? Was there an argument?

If the main reason you haven’t been getting together with the people you already know is that you have gotten too busy, take a good look at how you spend your time. Compare it with your real values and priorities (优先考虑的事) in life. Is your busy lifestyle really bringing you the quality of life that you want?

If you have become too busy for friends, why has this happened? Are you seeking material joys in your life at the expense of relationships with other human beings? Have you allowed your time to be over-committed because you never say ‘‘No” to anyone? Do you insist on doing things yourself that could be delegated to others? If so, why? Do you believe that everything depends on you?

Examine whether the way you are now spending your time exactly reflects your deepest values and priorities. Make sure that you schedule enough time for the things that are truly most important to you.

If you really want to keep friends in your life, make a space in your schedule, and a space in your heart for them.
