A warm drink of milk before bed has long been the best choice for those wanting a good night’s sleep. But now a study has found it really does help people nod off（打瞌睡）—if it is milked from a cow at night.
Researchers have discovered that “night milk” contains more melatonin(褪黑激素), which has been proven to help people feel sleepy and reduce anxiety（焦虑）.The study, by researchers from Seoul, South Korea, involved mice being fed with dried milk powder（奶粉） made from cows milked both during the day and at night. Those given night milk, which contained 10 times the amount of melatonin, were less active and less anxious than those fed with the milk collected during daytime, according to the study published in The Journal of Medicinal Food.
Night milk quickened the start of sleep and caused the mice to sleep longer.
While the effect of cow milk harvested at different time has not been tested on humans up to now, taking melatonin drugs has been suggested to those who have trouble falling asleep at night.
Previous （以前的）studies have also showed that milk can be excellent for helping sleep because of the calcium content, which helps people to relax.

If you could have one superpower, what would it be?
Dreaming about whether you would want to read minds, see through walls, or have superhuman strength may sound silly, but it actually gets to the heart of what really matters in your life.
Every day in our work, we are inspired by the people we meet doing extraordinary things to improve the world.
They have a different kind of superpower that all of us possess: the power to make a difference in the lives of others.
We’re not saying that everyone needs to contribute their lives to the poor. Your lives are busy enough doing homework, playing sports, making friends, seeking after your dreams. But we do think that you can live a more powerful life when you devote some of your time and energy to something much larger than yourself. Find an issue you are interested in and learn more. Volunteer or, if you can, contribute a little money to a cause. Whatever you do, don’t be a bystander. Get involved. You may have the opportunity to make your biggest difference when you’re older. But why not start now?
Our own experience working together on health, development, and energy the last twenty years has been one of the most rewarding parts of our lives. It has changed who we are and continues to fuel our optimism about how much the lives of the poorest people will improve in the years ahead.

Enough ＂meaningless drivel＂. That’s the message from a group of members of the UK government who have been examining how social media firms like LinkedIn gather and use social media data.
The House of Commons Science and Technology Committee’s report, released last week, has blamed firms for making people sign up to long incomprehensible legal contracts and calls for an international standard or kitemark (认证标记) to identify sites that have clear terms and conditions.
＂The term and conditions statement that we all carelessly agree to is meaningless drivel to anyone,＂ says Andrew Miller, the chair of the committee. Instead, he says, firms should provide a plain-English version of their terms. The simplified version would be checked by a third party and awarded a kitemark if it is an accurate reflection of the original.
It is not yet clear who would administer the scheme, but the UK government is looking at introducing it on a voluntary basis. ＂we need to think through how we make that work in practice,＂ says Miller.
Would we pay any more attention to a kitemark? ＂I think if you went and did the survey, people would like to think they would,＂ says Nigel Shadbolt at the University of Southampton, UK, who studies open data. ＂We do know people worry a lot about the inappropriate use of their information.＂ But what would happen in practice is another matter, he says.
Other organisations such as banks ask customers to sign long contracts they may not read or understand, but Miller believes social media requires special attention because it is so new. ＂We still don’t know how significant the long-term impact is going to be of unwise things that kids put on social media that come back and bite them in 20 years’ time,＂ he says.
Shadbolt, who gave evidence to the committee, says the problem is that we don’t know how companies will use our data because their business models and uses of data are still evolving. Large collections of personal information have become valuable only recently, he says.
The shock and anger when a social media firm does something with data that people don’t expect, even if users have apparently permission, show that the current situation isn’t working. If properly administered, a kitemark on terms and conditions could help people know what exactly they are signing up to. Although they would still have to actually read them.
1.What does the phrase ＂ meaningless drivel＂ in paragraphs 1 and 3 refer to?
A.Legal contracts that social media firms make people sign up to.
B.Warnings from the UK government against unsafe websites.
C.Guidelines on how to use social media websites properly.
D.Insignificant data collected by social media firms.
2.It can be inferred from the passage that Nigel Shadbolt doubts whether _______.

D.the kitemark would help companies develop their business models
3.Andrew Miller thinks social media needs more attention than banks mainly because _______.
A.their users consist largely of kids under 20 years old
B.the language in their contracts is usually harder to understand
C.the information they collected could become more valuable in future
D.it remains unknown how users’ data will be taken advantage of
4.The writer advises users of social media to _______.
A.think carefully before posting anything onto such websites
B.read the terms and conditions even if there is a kitemark

Direction：Read the following three passages. Each passage is followed by several questions or unfinished sattments. For each of them there are four choices markedA, B, C and D. Choose the one that fits best according to the information given in the passage you have just read.
(A)
One early morning, I went into the living room to find my mother reading a thick book called Best Loved Poems to Read Again and Again. My interest was aroused only by the fact that the word “Poems” appeared in big, hot pink letters.
“Is it good?” I asked her.
“Yeah,” she answered. “There’s one I really like and you’ll like it, too.” I leaned forward.
“‘Patty Poem,’” she read the title. Who is Patty? I wondered. The poem began:
She never puts her toys away,
The poem was just three short sections. The final one came quickly:
And I’ll be sad.
A terrible sorrow washed over me. Whoever Patty was, she was a mean girl. Then, the shock.
“It’s you, honey,” My mother said sadly.
To my mother, the poem revealed a parent’s affection when her child grows up and leaves. To me, the “she” in the poem was horror. It was my mama who would be sad. It was so terrible I burst out crying.
“What’s wrong?” my mother asked.
“Oh Mama,” I cried. “I don’t want to grow up ever!”
She smiled. “Honey, it’s okay. You’re not growing up anytime soon. And when you do, I’ll still love you, okay?”
“Okay,” I was still weeping. My panic has gone. But I could not help thinking about that silly poem. After what seemed like a safe amount of time, I read the poem again and was confused. It all fit so well together, like a puzzle. The language was simple, so simple I could plainly understand its meaning, yet it was still beautiful. I was now fascinated by the idea of poetry, words that had the power to make or break a person’s world.
I have since fallen in love with other poems, but “Patty Poem” remains my poem. After all, “Patty Poem” gave me my love for poetry not because it was the poem that lifted my spirits, but because it was the one that hurt me the most.

Failure is probably the most exhausting experience a person ever has. There is nothing more tiring than not succeeding.
We experience this tiredness in two ways: as start-up fatigue(疲惫) and performance fatigue. In the former case, we keep putting off a task because it has either too boring or too difficult. And the longer we delay it, the more tired we feel.
Such start-up fatigue is very real, even if not actually physical, not something in our muscles and bones. The solution is obvious though perhaps not easy to apply: always handle the most difficult job first.
Years ago, I was asked to write 102 essays on the great ideas of some famous authors. Applying my own rule, I determined to write them in alphabetical(按字母顺序), never letting myself leave out a tough idea. And I always started the day’s work with the difficult task of essay-writing. Experience proved that the rule works.
Performance fatigue is more difficult to handle. Though willing to get started, we cannot seem to do the job right. Its difficulties appear so great that, however hard we work, we fail again and again. In such a situation, I work as hard as I can-then let the unconscious take over.
When planning Encyclopaedia Britannica (《大英百科全书》), I had to create a table of contents based on the topics of its articles. Nothing like this had ever been done before, and day after day I kept coming up with solutions, but none of them worked. My fatigue became almost unbearable.
One day, mentally exhausted, I wrote down all the reasons why this problem could not be solved. I tried to convince myself that the trouble was with the problem itself, not with me. Relived, I sat back in an easy chair and fell asleep.
An hour later, I woke up suddenly with the solution clearly in mind. In the weeks that followed, the solution which had come up in my unconscious mind provided correct at every step. Though I worked as hard as before, I felt no fatigue. Success was now as exciting as failure had been depressing.
Human beings, I believe must try to succeed. Success, then, means never feeling tired.
