Imagine you are taking a walk on thebeautiful beach. Just then, your feet step over something and you hear a crack(噼啪声) —an emptyplastic bottle. Things like this are happening more often because of searubbish.

    Studies show that 80% of all the waste isfrom the land. The waste is mainly plastics (塑料制品)which are really hard to degrade (降解). So the rubbishwill remain there for a long time. Some of the pollution is causedaccidentally. For example, about 10,000 product-filled boxes are lost at seaevery year from business ships. Sometimes people just throw things into thewater from boats or land. Many large rubbish areas are formed in the NorthPacific Ocean.

    Thankfully, the situation isn't ignored (忽视). Groups like the National Oceanic and Atmospheric Administration (NOAA)are taking action to help clean the sea. Since 2006,76 projects have clearedout 3,814 metric tons (公吨) of rubbish from the sea.Methods of rubbish cleaning include using machines to remove (移除) the waste away from the surface of sea water. Besides, specialnets are set by the mouths of rivers to stop the rubbish before it reaches thesea. If everyone does his part, sea rubbish seems like a problem that can besolved.

My holiday is coming. Yesterday I asked my friends about the best way to travel in the USA. They said the best way was to go by bus and told me the reasons. 

 To fly, of course, is the fastest way, but you can't see anything during your stay in the air but the blue sky and white clouds. So it's not very interesting to you. And the cost is very high. 

To travel by train is relaxing, because you can walk and buy food and drinks on it. You can also see cities and the countryside through the windows. But sometimes it's crowded on the train. And it's hard to buy train tickets during holidays. 

To travel by bus is easy, cheap and convenient, though not so fast as travelling by plane or so comfortable as by train. You can find buses almost in every city, big or small. That makes travel easy. 

I took their advice. So I decided to take a bus to the south coast for an interesting trip. 

"I am Peppa Pig. This is my little brother George! This is Mommy Pig and this is Daddy Pig! " Do you know this family? I like them very much. Peppa Pig is from England, and she is four years old. Her favorite thing is to play with her best(最好的) friend Suzy and her brother George. Who's George's best friend? Peppa? No! His best friend is his dinosaur(恐龙). He takes(带着) his dinosaur everywhere. Mommy Pig is beautiful. She cooks for the family. Daddy Pig sometimes cooks for them, too. They often jump in muddy puddles(泥坑) with Peppa and George. They are very happy.

Lake Tahoe is the best place to go during winter vacations. You will have a lot of fun if you follow these tips(提示).

The first thing you should do is to wear at least(层) three layers(层) clothes. If you don't, you will have a cold!

You should also go skiing(滑雪) for at least one day. If you don't, your trip to Lake Tahoe will be boring.

Stay there for at least three days and two nights. If you don't, you won't enjoy yourself there. You may spend a lot of time on the way. It will be a waste of time and money.

Also, here are some things you shouldn't do at Lake Tahoe.

First, don't drive on the highway when it's snowing, or a traffic jam(交通堵塞) will make you angry. Second, don't try the sk i resort(度假村) food. Believe me , it's terrible. Bring your own food. At last, be careful when you sk i by yourself. Skiing is a dangerous sport. When you are skiing, you may fall down, get hurt or even die.
