Medical experts say most Americans do not get enough sleep. They say more Americans need to take a nap—that is to rest for a short period in the middle of the day. They give people advice to sleep lightly before continuing with other activities. The experts say naps might improve health by reducing pressure.

Some European and Latin American companies have supported the idea of napping for many years. They ask people to leave work, go home and have a nap before returning. In the United States, some companies let workers rest simply in their offices. They believe this can help workers make fewer mistakes and also increase the amount of work that a person can do.

Sleep experts say it is likely that people make more mistakes at work than at other times. They say people should not carry out important tasks when they feel sleepy. And they say the best thing to do is to take a nap. About twenty minutes of rest is all you need. Experts say this provides extra energy and can increase your effects until the end of the day. But experts said that a nap should last no more than twenty to thirty minutes. A longer nap will put the body into deep sleep and waking up will be difficult.

A.a story bookB.a poster

文章大意:本文是一篇记叙文。文章主要介绍了不同的国家或地区赠送礼物的习俗礼仪。

【推荐1】Whether it is for a special festival, to express thanks or to just let someone know that you care about them, giving gifts is a common way. The purpose of giving gifts may be similar, but the tradition is different from country to country. A gift of respect in one place may be considered rude in another. Take a look at three gift-giving traditions.

India

If you’re invited to someone’s home in India, you should bring a small gift, whether it’s a box of chocolates or some flowers. Gifts shouldn’t be wrapped in black or white colors, because they are considered unlucky. Instead, use bright colors such as green, red or yellow. When giving money for any situation, it should have an odd number (奇数) value. That’s believed to bring good luck. Instead of receiving a gift with both hands, Indians generally only use their right hand because left hands are considered unclean.

Japan

For most Japanese, the manners of giving presents are more important than the gifts themselves. The correct way is to present or receive gifts with both hands. Every gift should be wrapped. That’s because un-covered gifts are considered impolite. To show politeness and thanks, those who are receiving the gift may turn it down once or twice before finally accepting it. Gifts should be given in pairs, but four should be avoided just like in China. Lucky numbers also include eight. Eight is said to bring prosperity (兴旺).

Native America

While it may be common for guests to prepare gifts for hosts, this is different in Native American communities. From weddings to birthday celebrations, guests are the ones who receive gifts. Gifts are usually homemade arts and crafts (工艺) – made by hand to show love, respect and thanks.

1. Usually, people around the world give gifts not for ________.
A.expressing thanksB.a special holiday
C.showing love and respectD.showing your richness
2. Which of the following is not true according to the passage?
A.In India, people usually give 701 rupees (卢比) as a gift to celebrate one’s birthday.
B.Chinese people consider four an unlucky number while eight is thought to bring prosperity.
C.Japanese people use both hands to present or receive gifts, but Indians only use their left hand.
D.In Native America, guests receive gifts instead of giving gifts at weddings.
3. From the passage, we can learn that ________.
A.when you give gifts, you should wrap them in bright colours
B.proper manners in one country may be impolite in another
C.Japanese people usually turn down the gifts if they don’t like them
D.American people don’t like giving gifts to others

【推荐2】The weather is closely related to our life. It is all around us all the time.     1     We cannot control it, but it often controls how and where we live, what we do, what we wear and what we eat. Read this passage and learn something about the weather.

    2     The weather is just the state of the atmosphere(大气)at any time, such as temperature, wind, rain, sun, etc.

    3     As we know, not every place on the earth gets the same amount of sunlight. Some places get more sunlight. So it’s warmer in those places.     4     Then those places have colder temperatures. These differences in temperature make the air and water move around the earth. The movement helps to take the heat energy from the sun across the earth. So the weather changes.

    5     Climate is a place’s weather over a long time. The weather changes from day to day and even from hour to hour. It can be sunny in the morning, cold and wet in the afternoon. But the climate changes very slowly over lots of years.

A.What is the weather?
B.What can weather do?
C.What makes the weather change?
D.Some places get little or no sunlight in winter.
E.What’s the difference between weather and climate?
F.We all like fine weather instead of bad weather.
G.It is an important part of our lives.

Albert Einstein, Isaac Newton and Charles Darwin—these great scientists, are all left-handed. Does this mean that left-handers are smarter than right-handers, as some people say?

Scientific studies show that left-handers have no higher IQ than right-handers. They are just good at different things.

Left-handers and right-handers usually use different sides of their brains (大脑). Right-handers use the left side more often, but left-handers use both sides more evenly (均衡地). We use the left side of our brain to work out problems. We use the right side to create (创造). Left-handers are good at creative things such as music, art and science. But it’s not all good news for them. They often forget names and places.

Left-handers make up just 7 to 10 percent of the world’s population (人口), according to the United Nations. They have to learn to use right-handed things. Life can sometimes be hard for them.
