At 9:30, Rose said, “I hate going to bed. I want to stay up and watch a show!” At 6:00 in the morning, her alarm clock went off. Her mother heard her say, “The only thing I hate more than going to bed is getting up in the morning!”

What does Rose have in common with thousands of kids? She is not getting enough sleep. Have you ever stayed up later than you should? If you have, you know that not getting enough sleep can leave you feeling tired and upset. You may have even noticed that it’s hard to think clearly and stay focused (专注的) when you are overtired.

Need some motivation (动机) to go to bed on time? Here are some important advantages (好处) of getting a good night’s sleep. After a good night’s sleep, we are more energetic, smarter and even happier.

Do you like to play sports? It has been shown that football players, swimmers and tennis players all perform better after a good night’s sleep. Your coach may not tell you this, but the simplest way to improve your performance is to get enough rest.

Do you want to improve your grade? Healthy sleep habits improve your memory and your ability to pay attention to tasks, making schoolwork seem easier. While you get a snooze, your mind is very busy so you needn’t get a good rest like a long sleep. Researchers have found that it’s easier to learn after a good night’s rest. So, it’s no surprise that students who get enough sleep get better grades than those who don’t.

【推荐2】It was once thought that only time could mend a broken heart, but now scientists think taking a couple of aspirin might be the best way to get over a break-up.
Previous studies have shown that people experience feelings of romantic rejection (失恋) in the same way that they experience physical pain. And Psychology Professor Water Michel, of Columbia University, also believes that the psychological pain of ending a relationship is similar to physical pain, and should be treated like any other injury. “When we speak about rejection experiences in terms of physical pain, it is not just a metaphor – the broken heart and emotional pain really do hurt in a physical way," he said. “When you look at a picture of the one who broke your heart, you experience a pain in a similar area of the brain which is activated when you burn your arm. ”
Research shows that people who are given a simple painkiller, like aspirin, are able to handle feelings of rejection better than those given a placebo (安慰剂) .
‘Take two aspirins and call me next morning’ would be a cold-hearted response to a friend’s late-night report of fresh heartbreak, but it has a solid basis in the research.
1. The aspirin is a kind of _________.
A.wineB.fruitC.dessertD.medicine
2. According to the passage, maybe taking aspirins can ______.
A.mend a broken heartB.burn your arm
C.make people feel painD.help people get over a break-up.
3. The underlined word “those” in Paragraph 3 means ______.
A.painsB.heartsC.peopleD.areas
4. The best summary for the passage would be “Broken-hearted? _______________ !”.
A.Just take an aspirin or two
B.Just call me at any time
C.Just wait for a long time
D.Just eat as much as you can

文章大意:本文主要介绍了几个有关巧克力的事实真相。

【推荐3】If you like chocolate, you’re not alone. Millions of people around the world say they can’t live without chocolate. But have you wondered if chocolate is bad for your health? Let’s separate the truth from the facts about this popular food.

Chocolate makes you happy

There are over three hundred chemicals in chocolate, which make your brain active and help you feel happy. For example, the obromine (可可碱) can help produce feelings of happiness and make you feel less stressed. The caffeine (咖啡因) in chocolate can give you more energy and is also found in coffee and tea.

Chocolate makes you fat

Chocolate is commonly seen as a kind of fattening food. In fact, cocoa beans are full of antioxidants (抗氧化剂) that are good for health. However, a lot of antioxidants are removed during the process to clear up their bitterness (苦味). Most store-bought chocolates have high sugar and fat, and only a little cocoa. Eating these and other high-fat chocolate desserts, like cakes and cookies, can really increase your weight.

Chocolate causes bad teeth

It’s not chocolate itself that causes bad teeth, but the sugar in chocolate products and bad teeth-brushing habits! In fact, it’s believed that cocoa butter forms a coating over our teeth, and this might actually protect rather than hurt them.

As with most things, chocolate only becomes a danger when you eat it too much. It’s important to remember that most of the advantages of chocolate come from cocoa. That’s why dark chocolate is the healthiest choice. So choose your chocolate wisely, eat it properly, and you’ll get the best of both happiness and health.
