Are you sometimes a little tired and sleepy in the early afternoon? Many people feel this way after lunch. They may think that eating lunch is the cause of the sleepiness. Or, in summer, they may think it is the heat. However, the real reason lies inside their bodies. At that time – about eight hours after you wake up – your body temperature goes down. This is what makes you slow down and feel sleepy. Scientists have tested sleep habits in experiments where there was no night or day. The people in these experiments almost always followed a similar sleeping pattern (模式). They slept for one long period and then for one short period about eight hours later.
In many parts of the world, people take naps(小睡) in the middle of the day. This is especially true in warmer climates, where the heat makes work difficult in the early afternoon. Researchers are now saying that naps are good for everyone in any climate. A daily nap gives one a more rested body and mind and therefore is good for health in general. In countries where naps are traditional, people often suffer less from problems such as heart disease.
Many working people, unfortunately, have no time to take naps. Though doctors may advise taking naps, employers do not allow it! If you do have the chance, however, here are a few tips about making the most of your nap. Remember that the best time to take a nap is about eight hours after you get up. A short sleep too late in the day may only make you feel more tired and sleepy afterward. This can also happen if you sleep for too long. If you do not have enough time, try a short nap – even ten minutes of sleep can be helpful.

Death Valley is the lowest, hottest, driest area in North America. This California National Park has less than 5 cm of rainfall a year and temperature up to 53℃ in summer. That’s enough to keep Americans away during the hottest months from June to August. But it is the high temperature and terrible heat that draw their most crazy fans, the foreign tourists. From all over the world, they come to the valley floor in cars, carrying maps and water bottles, and fanning themselves with newspapers to keep cool.
About 1.3 million visitors enter the park each year, from June through August. 90% of them are foreigners. They go there to experience the summer heat that gives Death Valley its name. The average high in July is 53.2 ℃ and the low 30 ℃. For August, the average high is 52.2 ℃ and the low 29.4 ℃.
So what do Americans think of the foreign visitors who arrive for the heat, just when locals from the United States try to avoid it? Park manager Brenda Henson says, “ The foreigners want to experience the heat in Death Valley. We think it’s crazy.”
In fact, Death Valley is a series of salt flats (盐滩) 225 km long and 6 km to 26 km wide. Birds and animals are largely absent, and only the hardiest plants have some chance of existence in this extreme place.
One tourist from Paris concluded, “ We come to it because we can tell all our friends and family that we’ve been to the hottest place in the world.”

Forgiving someone who has hurt you or let you down is never an easy thing. Several new studies, however, say that it could have a lot of health benefits. When you think of forgiveness, you probably don’t think of it as being a health or medical problem. Studies from Stanford University, on the other hand, show that something like anger can change your well-being.
When cartoon book characters like the Incredible Hulk get angry, they change colours and often gain special power. In the real world, anger is less obvious and may be more dangerous. That’s why Professor Fred Luskin, founder of the Stanford Forgiveness Project and author of Forgive for Good, says holding on to anger and hatred can harm your physical and mental health. Two new studies seem to show the same idea.
The studies find that people who are able to forgive feel less stress, less back pain, and less depression. They also have fewer headaches, lower blood pressure, and fewer problems on sleeping.
So it doesn’t matter if your anger is caused by the traffic or other things. Learning to let it go is important. Techniques such as deep breath or thought can help. Or just ask yourself if it’s worth hurting yourself by staying angry with someone else.
Forgiveness does not mean that you simply accept what happened and say it’s OK. Instead, it’s a way of making peace with yourself about what happened in the past.
1.The author of the passage tries to make his viewpoint clear ______.
A.by raising his own examples

A.support the viewpoint that anger and hatred harm physical and mental health
B.introduce a famous expert
C.let the reader know the different colours of cartoon faces
D.show how to control one’s temper
3.The underlined phrase“holding on to”in this passage possibly means“______”.
A.removing B.keeping up C.getting rid of D.learning about
4.The best title for this passage is probably _______.
A.Forgiveness B.Forgiveness Is Good for Health
C.A Secret to Keeping Health D.Anger Is Bad for Health
Puerto Rico may be part of the USA but its music and dance is a mixture of both Spanish and African rhythms. The country, as a result, is a mixture of very new and very old. It exhibits the open American way of yet retains the more formal Spanish influences. This is reflected in the architecture, not just the contrast between the colonial and the modern in urban areas but also in the countryside, where older buildings sit side by side with concrete schools and buildings.
However, if you do not wander beyond the tourist areas on the coast, you will not experience the real Puerto Rico.

North of the Cordillera is the karst (岩溶)country where the limestone(石灰石)has been acted upon by water to produce a series of small steep hills and deep holes. The mountains are surrounded by a coastal plain with the Atlantic shore beaches cooled all the year round by trade winds.

Most Puerto Ricans do not speak English and less than 30% speak it fluently. Second generation Puerto Ricans who were born in New York but who have returned to the island, are called Nuyoricans.
