My grandfather Jack is 96 years old, and he has an interesting life. He has travelled a lot in his life in the Far East. He visited the Taj Mahal in India and the Pyramids, in Egypt. He hunted (狩猎) lions in Africa, and rode a camel in the Sahara Desert. He says the most beautiful place he has travelled to is Kathmandu in Nepal.

    Jack has married twice. His first wife died when she was 32. He met his second wife Maria while he' was cycling round France. They have been married for 50 years, and they have lived happily in a small village since they got married.

    Jack says that he has never been ill in his life. The secret of good health, according to my grandfather, is exercise. He goes swimming every morning. He has done this since he was a boy. He also has a glass of wine every night! Perhaps that is his secret!

    Most teens need more than 9 hours of sleep each night. But about 1 in 4 teens has trouble in sleeping. Lack of sleep can affect everything from our feelings to how well we focus on tasks like studying. It can also influence sports performance, increase our chances of getting sick, and may lead to weight gain in some people.

    How can we get the sleep we need? Here are some ideas:

    Be active during the day. Get at least 60 minutes of exercise a day. Physical activity can decrease stress and help people feel more relaxed. Just don't work too close to bedtime because exercise can wake you up before it slows you down.

    Say goodnight to electronics. Experts suggest using the bedroom for sleep only. At least shut everything down an hour or more before lights out.

    Keep a sleep routine. Going to bed at the same time every night helps the body expect sleep. Creating a bedtime routine can improve this relaxation effect. Reading, listening to music, spending time with a pet, writing a diary or doing anything else can relax you.

    Expect a good night's sleep. Instead of worrying that you won't sleep, remind yourself that you can. Say "Tonight, I will sleep well." several times during the day. It can also help to practise breathing exercises or gentle exercises before bed.

    Everyone has a sleepless night once in a while. But if you regularly have trouble in sleeping and you think it's affecting your mood or performance, talk to your doctor.

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!

Hangzhou is a good city to live and visit. Many places like the West Lake and Lingyin Temple are very 1 . There are millions of people visiting them every year. But to me, I 2  Xixi Wetland Park. It is about ten kilometres from the West Lake. And it is China's first national wetland 3 . I didn't go there until last year 4  I have worked in Hangzhou for about 7 years. 

Last June, I got ill and had to have a 5  for days at home. The doctor saidI should get close to 6  often. He said the natural world would be better for my 7  than medicine. I listened to him and 8  the park with my husband for the first time. 

Tall trees, green grass and fresh air made me 9 . I forgot my busy work and illness. When I saw fish 10  freely in the river, I felt like I was a fish. My 311  said, "There are many rivers, 12  and marshes(沼泽) in the park. In fact, the waterways are over 100 km 13 . Over 50 kinds of fish and aquatic(水生的) animals are 14  here. This park is home to many animals. "

I'm not sure if the plants, fish and birds like the wetland park, but I 15  it. It really makes me relax.
