Do you know the reason why we feel tired in the middle of a class? Maybe you would say it’s because the teacher’s class is boring. However, the real reason is probably that we don’t have enough sleep. Here are what sleep researchers have found about how to sleep.

Why do we need sleep? Sleep helps our body grow and stay healthy. It also gives us energy, so we can be active all day. Doctors say: When you close your eyes and need a rest, sleep is just the very best!

How much sleep do we need? It is known that all of us naturally need no less than eight hours of sleep per night. When we sleep below six hours per 24, we’re at a higher risk of health problems. Some of us think we can make up any of those hours lost during the week on the weekends. Sadly, there is no storage(储存) system for sleep in the brain.

New-born babies can sleep 20—22 hours a day. Children need 10—12 hours of sleep a day. Teenagers need 8—10 hours of sleep a day, while grown-ups usually need 6—8 hours of sleep to keep active.

A new research suggests a kind of strong connection between purpose in life and sleep. People who have a greater sense of purpose usually have better physical and mental health, which in turn explains their higher-quality sleep. Perhaps developing a sense of purpose in life could be as useful at improving sleep as the healthy habits above.

If you have trouble sleeping, set a goal and go for it! Maybe it will help you to have a sound sleep!

【推荐1】阅读下面短文,根据短文内容回答问题。

A lift is very useful. It looks like a small room. It goes up and down all day.

In the past a worker stood in the lift. He or she operated (操作) it up and down. In modern (现代) lifts, there’s no worker. People walk in. They know which floor (楼层) they want to go to. They push (按) a button (按钮) and the lift goes to that floor. It’s very fast and easy.

Lifts are very important to us. Why? Think about a tall building. Maybe it has twenty floors. Maybe it has fifty or more. Who can walk up all the stairs (楼梯)? Maybe people can climb them once. Can someone climb thirty floors to an office every day? Can small children walk up to their rooms on the twenty-fourth floor? Of course not. We can have very high buildings because we have lifts. We could not have all the beautiful tall buildings without lifts, because it is too tired for people to climb the stairs every day.

2. What did a worker do when he or she stood in the lift?

【推荐2】根据短文内容,用符合语意及语法规则的词填空。

In 1901, an Austrian scientist discovered that there are four types of blood. These four blood types were named A, B, AB, and O. People have one of these four types.

Blood type O is the most common around the world. Blood type A is the second most common, and type AB is the least common. If people with type A blood are given type B blood, or people with type B blood are given type A blood, they will probably die.

In 1927, a Japanese doctor found out that people with different blood types also had different personalities. He said that people with type A blood are usually calm and serious; people with type B blood are curious, cheerful, and outgoing; people with type O blood are generous and honest; while those with type AB blood are often caring and talented.

More recently, a doctor in the United States wrote a book that links blood types and what people eat. For example, his book suggests people with type O blood should eat more meat and less bread. A diet for people with type A blood includes more vegetables. His book Eat Right for Your Type has been a hit with people who want to lose weight. However, Dr Peter D’Adamo believes that eating food that matches a person’s blood type can do more than help them lose weight. He thinks it will make the person healthier in other ways, too.

1. An ________ scientist discovered that there are four types of blood, Blood type A is ________ common than type AB.
2. It isn’t ________ to give type B blood to people with type ________ blood.
3. People with different blood types have different ________. People with type O blood are ________ and honest.
4. An American doctor found there was a relationship ________ blood types ________ food.
5. ________ a person eats food that matches his blood type, he will lose weight and _______ healthier in other ways.

【推荐3】请认真阅读下列短文,并根据所读内容在文章后表格中第56-65小题的空格里填入一个最恰当的单词。

Wind is a powerful force(力量) in nature. Wind energy is one of the causes of great waves in the world’s oceans. Winds can help create powerful storms, but wind is a force you can’t see but can surely feel. Its power can be used to create electricity for cities and the countryside.

Wind can also power many expressions in American English. Let’s start with a simple one. If you run like the wind, you are a very fast runner. After running, sometimes you can feel full of energy. The runner gets what we call a second wind. We use this expression when we are tired, but then get more energy to finish something. For example, sometimes I feel tired after work. But after a short rest and a cup of tea, I get my second wind. I’m ready to do something fun with my friends and family.

If you are doing something difficult, it is good to have the wind at your back. In this way, it is easier to go forward. It’s always more difficult to do something in a strong wind–unless you are sailing.

Knowing the direction of the wind is the most important part of sailing. When wind fills a sail, it makes the boat go faster. If you take the wind out of someone’s sails, you prevent them from reaching their goals. You create a barrier(障碍) or stop them in some way. In life, it’s lucky to have friends who want to fill your sails with wind and not take it out.

Let’s turn from sailing to music. Many songwriters use the image(形象) of wind in their songs. If something such as an idea is blowing in the wind, it is being discussed but has yet to be decided. When a singer sings “you don’t need a weatherman to know which way the wind blows,” he means that you don’t need someone in power to confirm something for you. Just trust yourself. You can find it out on your own. So, when you know which way the wind blows, you know what is going on.

Now you know which way the wind blows. Then how can you use these expressions properly? First, read them aloud and keep them in mind. Then, practice using them and test yourself. You know, practice makes perfect.
