Sleep is something we all do. But some people need to sleep more than others. Babies sleep most of the time. Children in school sleep about ten to twelve hours a night. Most adults sleep only seven or eight hours.{#blank#}1{#/blank#}All parts of our bodies have to rest after they work.. Our arms need a rest after we lift heavy thing, When we run fast, our legs work hard. They get tired. We have to rest them. Our brains workhard, too.{#blank#}2{#/blank#} We can sit quite still and rest our arms andlegs. But our brains aren't resting. They go right on thinking as long as weare awake.

      Our brains slow down a bit when we sleep and dream.{#blank#}3{#/blank#} Instead of thinking wide-awake thoughts, our brains make up dreams. Some dreams are very pleasing. Some are not. Most of thetime we forget them when we wake up.

      Scientists have tried to find out what would happen if people were not allowed to sleep. They asked some people not to go to bed. The people stayed up all night and all the next day. They stayed up the next night too,and the day after. They played games, but they made mistakes. They forgot things.{#blank#}4{#/blank#} The people grew rude and mean. They became angry with their friends. Finally they were too tired to stand up. When they sat down, they fell asleep.

Scientists have found that if people are not allowed to sleep and to dream, they act in an unusual way.{#blank#}5{#/blank#}But we do know that we need it to stay well. So tonight have a goodsleep. Lie down under the covers. Shut your eyes. Let your thoughts wander.Soon you'll stop thinking. You'll be asleep.

B. When we are awake, they help us pay attention to the worldaround us

C. But babies, children, and adults—all of us need to haveour sleep

D. Good sleep helps to improve one's memory

E. No one knows why sleep is so good for us

    Doctors say anger can be an extremely damaging emotion, unless you learn how to deal with it. They warn that anger can lead to heart disease, stomach problems, headaches, emotional problems and possibly cancer.

    {#blank#}1{#/blank#} Some people express anger openly in a calm reasonable way. Others burst with anger, and scream and yell. But other people keep their anger inside. They can not or will not express it. This is called repressing anger.

    For years many doctors thought that repressing anger was more dangerous to a person's health than expressing it. They said that when a person is angry, the brain releases the same hormones (荷尔蒙).They speed the heart rate, raise blood pressure, or sugar into the blood, etc. {#blank#}2{#/blank#}

    Some doctors say that both repressing and expressing anger can be dangerous. They believe that those who express anger violently may be more likely to develop heart disease, and they believe that those who keep their anger inside may face a greater danger of high blood pressure.

    {#blank#}3{#/blank#} They say the first step is to admit that you are angry and to recognize the real cause of the anger, then decide if the cause is serious enough to get angry about. If it is, they say, “{#blank#}4{#/blank#}”  Wait until your anger has cooled down and you are able to express yourself calmly and reasonably.” Doctors say that a good way to deal with anger is to find humor in the situation that has made you angry. {#blank#}5{#/blank#}

A. They say that laughter is much healthier than anger.

B. Expressing anger violently is more harmful than repressing it.

C. Doctors say the solution is learning how to deal with anger.

D. Anger may cause you a cancer.

E. Do not express your anger while angry.

F. Anger is a normal emotion that we all feel from time to time.

G. In general the person feels excited and ready to act.

They Just Can't Help It

    My theory is that the female brain is mainly built for empathy — the ability to understand other people — and that the male brain is mainly built for building systems. {#blank#}1{#/blank#} For example, women are more likely to read magazines on fashion and parenting, while men will choose magazines that feature computers and sport.

    You may think that these preferences are influenced by the way people are taught to behave when they are growing up. However, this is not the case. A new study carried out at Cambridge University shows that newborn girls look longer at a face, and newborn boys look longer at a mobile.{#blank#}2{#/blank#} It has also been observed (that girls are better at noticing signs of changes in other people's feelings. Boys, however, seem to enjoy building toy towers and playing with toys which have clear functions. {#blank#}3{#/blank#} People whose jobs are in the construction industries are almost male. Math and engineering, which require high levels of systems-thinking, are also male-chosen disciplines. Why do men and women have the difference? Actually women have four times as many brain neurons (神经) that connect the right and left part of their brains. Because of it, women have a better ability to multitask than men. {#blank#}4{#/blank#} Men tend to focus on a limited number of problems at a time. They will separate themselves from problems and view tasks as independent from one another.

    Some people may worry that I am suggesting one gender (性别) is better than the other, but this is not the case. My theory says that males and females differ in the kinds of things that they find easy, but that both genders have their strengths and weaknesses. {#blank#}5{#/blank#} It is not true. The study simply looks at males and females as two groups, and asks what differences exist, and why they are there.

A. Generally speaking, there are clear differences.

B. Their preference for building systems may change over time.

C. You can see the same kind of pattern in the adult workplace.

D. They will consider many sources of information at the same time.

E. It is important to stress that the female brain may be built more for empathy.

F. That suggests certain differences between male and female brains are biological.

G. Others may think the theory creates a belief of what a particular type of person is like.

    Recently, I've been following a simple rule that is helping me crush procrastination(拖延症) and making it easier for me to stick to good habits at the same time. {#blank#}1{#/blank#} There are two parts to the 2-Minute Rule.

    Part 1—If it takes less than two minutes, then do it now.

    {#blank#}2{#/blank#} For example, washing your dishes immediately after your meal, tossing the laundry in the washing machine, taking out the garbage, sending that email, and so on.

    If a task takes less than two minutes to complete, then follow the rule and do it right now.

    Part 2—When you start a new habit, it should take less than two minutes to do.

    Can all of your goals be accomplished in less than two minutes? Obviously not. But, every goal can be started in 2 minutes or less. {#blank#}3{#/blank#}

    It might sound like this strategy is too basic for grand life goals, but I beg to differ. The 2-Minute Rule works for big goals as well as small goals because of the inertia(惯性)of life. {#blank#}4{#/blank#} I love the 2-Minute Rule because it embraces the idea that all sorts of good things happen once you get started.

    The most important part of any new habit is getting started—not just the first time, but each time. It's not about performance, it's about consistently taking action.

    I can't guarantee whether or not the 2-Minute Rule will work for you. {#blank#}5{#/blank#} Anyone can spare the next 120 seconds. Use this time to get one thing done. Go.

A. I call this little strategy the "2-Minute Rule".

B. And that's the purpose behind this little rule.

C. Here's what you need to know to stop procrastinating.

D. Once you start doing something, it's easier to continue doing it.

E. But, I can guarantee that it will never work if you never try it.

F. The goal is to make it easier for you to get started on the things you should be doing.

G. It's surprising how many things we put off that we could get done in two minutes or less.

    Lemon water is pretty popular. It's offered as a free upgrade to regular water at pretty many restaurants.{#blank#}1{#/blank#}, others are devotees of the possible health benefits. Here's what may happen if you take up the lemon water habit.

    Easier weight loss

    Studies in mice indicate that the antioxidants(抗氧化剂) in lemons can reduce weight gain despite a high-fat diet. More studies are needed to determine if the results can be applied to humans, but anecdotal evidence is favorable. People who drink lemon water regularly report easier weight loss, though it is unclear if the combination of lemon and water is the fundamental driver.{#blank#}2{#/blank#}.

    Get enough vitamin C

    Vitamin C is an important antioxidant that has a ton of health benefits. It can only be gotten from food as our bodies don't produce it alone. Getting your RDA (Recommended Daily Allowance) of vitamin C can lower the risk of heart disease, stroke, and high blood pressure. Vitamin C is good for your skin and bonds with free radicals (自由电子) that accelerate aging.{#blank#}3{#/blank#}, but they're a great source nevertheless.

    Stabilized moods

    Studies have found that smelling lemon scent reduces stress hormones that regulate mood. Drinking lemon water offers this benefit as well as the vitamins and potassium(钾) in the fruit. {#blank#}4{#/blank#}, and high blood pressure is related to stress, so not getting enough potassium can certainly affect your mood. All in all, lemon water can be a calming drink.

    In the end, drinking water is never a bad call, and there is absolutely no reason not to add lemon to it. Drinking lemon water provides some helpful nutrients and antioxidants. Give it a try!{#blank#}5{#/blank#}.

A. Lemon is a common smell in all manner of cleaning products

B. Potassium plays a huge part in regulating blood pressure

C. There is nothing to lose

D. Lemons aren't the highest in vitamin C

E. While some people drink it simply because of its taste

F. If adding lemon to water can encourage people to drink more

G. It could be that drinking more water helps dieters to feel full and avoid overeating

    Summer is the perfect time to relax. As you plan for your trip, here are some tips on how to protect yourself. {#blank#}1{#/blank#}.

    Fight against the mosquitoes in the hot spots.

    There are many mosquito-borne illnesses in tropical regions, which are traditionally vacation hot spots. Therefore, mosquito repellent (驱蚊剂) that contains DEET should be an essential item in your travel bag.

    {#blank#}2{#/blank#}.

    In lesser-developed countries there is less equipment for clean water and public health. If you can't avoid unhealthful water, make sure you bring along a tea or coffee—making pot that will boil water for you. You'd better buy a case or two of water and check that all bottle caps are sealed to assure the bottled water isn't just a refilled bottle of dirty tap water.

    Always protect your feet.

    It's best to wear slippers in the shower, but if you must be barefoot, put a towel down on the floor. {#blank#}3{#/blank#}. You should never walk barefoot in any area of a foreign country, including your hotel room.

    Be sure to eat safe fruits.

    {#blank#}4{#/blank#}. They may have been washed in the same water, or wiped with the same rag used to clean work surfaces in kitchens. The best advice is to bring your own peeler（削皮器）so that you know that something clean has been applied to the fruit.

    Enjoy the smell of roadside stands, not the food.

    Unless the food is piping hot when served, it's best to stay away from roadside stands, no matter how good the smell of the food might be. If you are concerned about whether a restaurant is clean, order the food to go. {#blank#}5{#/blank#}.
