Hello,everyone!on the past few days,ham and sausage are the most famous words.Beacse WHO said that Processed meat is on the top of the list which may cause cancer.In the same level ,there are the cigarettes and arsenic .What is arsenic?In China,we call it 砒霜.It is terrible to us.And they also said eating just 50 gram of processed meat one day increases the risk of cancer by 18 percent. So what does 50g look like?It’s maybe two slices of smoked ham or half a hot dog.A famous expert suggest the public to avoid processed meat when possible and to have a vegetable salad for lunch rather than a sandwich. And they also said that We have known the probable link between processed meat and cancer, which is supported by massive evidence. It maybe a bad news for hot dog

lovers.But this doesn't mean we need to stop eating any processed meat. if someone eat lots of it and he may need to think carefully about whether he should cut it down.In fact,there are a lot of choices for us. We could try having fish for our dinner instead of sausages, or choosing to have a fruit salad for lunch.

And someone may say:”Why is processed meat so bad?” Processed meat is which has been salted, cured, smoked, or any other natural or chemical processes to make them delicious or improve preservation. So processed meat may contain sodium nitrite and sodium nitrate, which are salts added to the meat to preserve it.In the body, they can form the compounds that can damage DNA.

Nowdays,many person may do something which is harmful to their health,as they think cancer are far away from them,this words only usesd on newspaper or television. in my opinion,this idea is highly irresponsible.If something bad happen，the total home will be destroy by you. So please ,take care of yourself,not only for you,but also for your family.

Our Colourful School Life

Hello, everyone .My name is Chen

Ziying. I’m from Shandian Middle School and in Class 2, Grade 3. I’m 16 years old. I like listening to pop music and making friends a lot. My favourite sport is running and I am very good at it. I enjoy reading English as well. I’m pleased to come to the match.

Today the title I Speak is “Our Colourful

School Life”.

My school is very big. We have a big

playground with lots of trees around it. There are all kinds of flowers in our school yard. As my school is far from the factories, we can breathe the fresh air and drink the clean water every day.

We have great fun at school at school.

After class we play games and do plenty of sports such as doing eye exercises, doing morning exercises, playing basketball, playing football and so on. Sometimes I would like to play computer. I can get some information I want. It makes me more interested in study.

The students in our school work hard at

their lessons. They take an active part in many activities that help to improve their qualities

and health. All the students respect their teachers and they get on well with each other.

When we study in groups, we can talk about the problems and overcome difficulties together. Everyone also can have chances to express their own ideas. We make our plans to study and learn to make good use of time. We can also learn to think by ourselves. Last term we began to have the English Corner. On Friday afternoon not only a large number of students but also some teachers took part in it. Thanks to the corner, we made great progress with speaking-English.

I enjoy all the time in my school because I can bring many things such as feeling, knowledge and other things I need, especially the teachers in our school are friendly and helpful to us .We have a colourful school life and I feel proud of it. It’s one of the best schools in my heart!

I love my classmates.

I love my teachers

I love my school.

Welcome to our school.

So much for the speech.

Thanks a lot.
