阅读下列内容，从每小题所给的A、B、C、D四个选项中选出一个最佳答案。

    During the years of game making, there have been a number of games. Many old games have gone since modern games came out.

Teachers at a primary school asked their students to write articles about games they knew and were surprised by the results. Half of the 50 children in one of the classes wrote about online games. It is easy to see that traditional games like hide-and-seek and jump rope games are unfamiliar(不熟悉的) to many of today's schoolchildren. They like to play computer games, especially in the cities, with the rising popularity of TV, the Internet, video and online games.

    An educationist said, "Traditional games used to be so popular, but over just a few years, kids have forgotten them. It's sad."

    The games that many parents once played were generally outdoor activities which were enjoyed by students during breaks or after school. They usually needed several partners and just a little space.

    Jump rope games, for example, have always been popular in many countries around the world. A kind of jump rope game, played with rubber bands(橡皮筋) which are connected together to make a long rope, is played in many countries.

    Rubber band jumping was once very popular in primary schools. Girls loved playing this game. It can help kids practise their jumping skills and develop coordination(协调性), and also help them meet lots of friends.

    It is common these days to see primary school students spending their breaks in the classroom. They are busy with their studies.

    "When we were young, we played many different outdoor games, but today's children don't know what to play or how to play," a 40-year-old mother said. "They don't know what teamwork is."

Being worried by the situation, educational officers have tried to make some programmes to educate children on traditional games.

    Some people like to collect stamps. Others prefer posters or coins. But Pinky Bhutia is different. She collects children. In her mountain village, in Sikkim, she is known as the wonderful young woman who adopts(领养) all the children she can.

    Pinky was 14 when she adopted her first child, a Nepali baby girl, whose patents passed away. Pinky's parents did not mind. Pinky left school and started working full time because she had a baby to feed. Today , she has twelve adopted children, and two sons from her marriage.

    Pinky is about 30 years old and she comes from a common family. If you passed her on the street, you wouldn't give her a second look. She lives in a brown mud-washed(泥刷的) house. There is a vegetable garden outside. Red hens with noisy chicks run all over the garden looking for food.

    If you ask her why she provides a home for so many kids, she smiles shyly. But her eyes are serious. "I know what it is to be poor and hungry." As a child, her only dream was to eat a full meal, and her favorite amusement was watching people with shoes and imagining what it felt like. By adopting poor and homeless children she is making sure that they never feel that hopeless.

    Pinky feels very proud when she sees her children happy and bright, her oldest baby, Aarita Rai, is now 20 years old, Then, there is 19-year-old Nimbe who came to Pinky because her mother was unable to look after her. She started to work in a government office two years ago. Ten-year-old Bhim and 14-year-old Kumar came to Pinky five years ago, after their father's death. They started living on a patch of land given by Pinky and grew vegetables for sale.

    "I like children. It's not one more mouth to feed but one more soul saved," Pinky says.

    Tom was walking through the forest with his axe (斧子) when a sapling (树苗).Called to him and stopped him on his way.

    "Could you please help me clear away these trees.my kind friend?  They are stealing (窃取)all of my sunshine. There is no room because of the trees .so my roots cannot grow freely. I cannot feel the wind with the trees above me."

    Tom decided he could do this favor for the poor sapling. He swung his axe and cleared the trees around the sapling.

    But after Tom made space for the sapling, the hot sunlight dried his leaves. Then there was a heavy rainstorm. The poor sapling couldn't stand(忍受)the weather.

    "Oh, foolish one." said a farmer who was passing by. "The taller trees may seem like they're taking your sunshine, space and wind form you, but they're actually helping you. They protect you from sunburns, heavy rain and other bad weather. _____.You only see them taking your space, but you don't see how they help you. One day when you grow up, you might be the one to protect other saplings."

①Ahh...ahhhh...aaahhhhchooo! That sneeze is uncovered, and so the germs(细菌) fly through the air. It is pretty awful to think about, but have you ever wondered about the germs in your body? They are very small organisms(生物体) that live inside us. An organism is a living thing. Germs area live, and they can cause us to get sick. It is impossible to keep germs out of our bodies. They are so tiny that we do not even know they are coming inside our bodies. The only way we know that germs have made us sick is when we begin to feel symptoms. We might get a fever or a sore throat. We might have a runny nose or a headache.

②Germs are usually spread through the air They come out in a sneeze, a cough, or a breath. They can also be spread by saliva(唾液), sweat(汗), or blood. Sometimes, they come from touching something. For example, a person can touch his or her nose and then touch a doorknob(门把手). If someone else touches that doorknob right away, he or she can pick up those germs.

③How can you protect yourself from germs? The most important way to do this is to wash your hands. Soap and water area germ's enemies. They wash the germs away. This is why it is so important to wash your hands throughout the day. But a quick splash(飞溅) will not work. Hands should be washed for about twenty seconds.

④Staying healthy also keeps germs away. This means getting enough rest and not being too tired. It also means having good foods and exercising. These are germ-fighting secrets!

Everyone knows a power nap(小睡) feels good. If power naps fit right into your normal sleep/ wake cycle(周期), they can really help you get through the day.

Our bodies have a timekeeper called the circadian rhythm(昼夜节律). It helps you fall asleep, wake up, and feel more or less tired throughout the day. It also changes during the day, as shown in the picture below.

As we can see, the circadian rhythm is low between 2:00 and 4:00 pm. To improve your attention, productivity and memory, a power nap may be the answer.

In studies, a 10- minute afternoon nap is the best in improving your energy. And, it makes sense to nap around 2:00 pm.

Besides the length and the timing, there are other ways to have power naps:

●Try deep- breathing as you start.

●Choose a quiet, darkened place. A sleep mask may help.

●Lie down or sit in a comfortable chair.

●Listen to soft music.

●Give yourself a few minutes to refresh after your nap. Try a bit of stretching(伸展) and walking around.
