In San Francisco, there is a special group of volunteers. They call themselves Friends of the Urban (城市的) Forest (FUF). These volunteers want to {#blank#}1{#/blank#}. Every year, the FUF plants nearly 1,000 trees.

The FUF welcomes new volunteers all year round and in all parts of its work. On Weekend Planting Days, FUF volunteers work with common citizens (市民) to plant trees. The planting usually runs from 9 a.m. to 1 p.m. After the work is done, everyone {#blank#}2{#/blank#} over a community lunch.

On Thursday Planting Days, the FUF plants "replacement (替换) trees". As their name suggests, these trees replace trees {#blank#}3{#/blank#}. Planting Leaders are very experienced volunteers. They are able to help other volunteers at planting events. Planting Leaders usually wear a special FUF T-shirt. Some new volunteers know little about "replacement trees". They can easily find Planting Leaders and {#blank#}4{#/blank#}.

All over the world，men and women，boys and girls play sports because they're important for everyone.If you have time to do sports

People think running is easy and cool now.Many people don't have enough time to play sports，so they start running in the morning or evening.In the past，running in the street was a little silly，keep fit or relax themselves.

Running was not popular at school in the past.In some schools，when it rained，the playground became too wet and children couldn't play football，running becomes popular now.Good sports clothes，comfortable shoes and your favorite music are helpful for running.

Every year in April，the London Marathon（马拉松） comes.People from all over the world run in it.Interestingly，but now even people who are unfit come to join in it.It's not because marathons become easier，but people become more interested in running.

So what are you waiting for？Just run from today.

"Dreams may be more important than sleep. We all need to dream," some scientists say.

Dreams take up about one quarter of sleeping time. People have several dreams each night. Dreams are like short films. They are usually in colour. Some dreams are like old films. They come to us over and over again. That may be because the dreamer is worrying about something. Dreaming may be a way of trying to find an answer.

Some people get new ideas about their work from dreams. They may be thinking about their work all day. These thoughts can carry over into (延续到) dreams.

Sometimes we wake up with a good feeling from a dream. But often we can't remember the dream. Dreams can disappear quickly from memories. 

Too much dreaming can be harmful(有害的). The more we sleep, the longer we dream. The mind is hard at work when we dream. That is why we may have a long sleep but still feel tired when we wake up.

Some people like to visit famous cities and see beautiful views. The provinces in the southwest of China, such as Sichuan Province and Yunnan Province, are famous for their natural beauty. Lots of people want to go on vacation there. But some people are not {#blank#}1{#/blank#} in famous cities. They like to adventure (冒险) in wild places. But not everyone can take such an adventure. It {#blank#}2{#/blank#} a lot of skills (技能). Sometimes you will find yourself in danger. For example, maybe you will meet snakes in those places. There are also some other dangerous {#blank#}3{#/blank#} for people who don't have enough skills. A few years ago, ten people from Hangzhou {#blank#}4{#/blank#} to explore a karst cave (探索溶洞). But after a few hours, they found they couldn't get out. The government sent ten policemen and doctors to {#blank#}5{#/blank#} them. At last, they all left the dangerous place safely.
