Scientists develop purple, cancer fighting tomato

happy weekend for everyone!!
This weekend I read a news which is"Scientists develop purple, cancer fighting tomato".
This article introduces that British biologists studies out a gene engineer that they found a ingredient called anthocyanins,a type of antioxidant found in berries such as fruit blackberries and blackcurrants.This ingredient has turned out can decrease the possibility to get cancer.And it can be made in tomato,so scientists modified the tomato genetically turning it to purple with anthocyanins and experimented on the cancer-prone mice by feeding them on modified tomato,it proved that these mice can live longer than those which were fed on regular tomato.So, scientists primarily defined that the modified tomatos can make people healthier and take less risks to get cancer.
After reading the article,I feel thankful to the scientists who are working hard to figure out a lot of scientific problems for our health,so that people who are suffering from the disease have prospect to recover.They are really helpfull.
However,I also think that in primitive times,people lived in the world without any science technology,meawhile,they also lived in the world without cancer and terrible disease.But why today,in the more cilverlized and advanced times,we have so many untreatble diseases? We have people woking on them but we also have people dead because of them...
Today,we try best to modify the world,we creat a lot of new nouns,like transgene,clone and so on.But, there appears the new disease as well.I think this two situations have some kind of subrelationship between them.We do experiments and study on animals,plants and nature ,we created the usefull,but nature created disease...
So,in my opinion, not every modifiction is practicble for our nature.Scientists should consider a second for what should be continued or stopped.

The story of stuff

After watching the video The story of stuff, I feel upset.Considering more consumption means more pollution more trash and more destruction for the earth,I feel so shameful to tell someone I like shopping when being asked.for a long time, we don't realize what we are doing now.Shopping makes people self-satisfied.Some of us go shopping for enjoying,some are for killing time but some are for competition,gorvernment and corporation encourage people consuming for economy.for different reasons and different purposes,people go shopping.But, we never realised how harmful we do for envirnment and for the earth.I don't want to emphsis more cause this video has told more. I think a part of poeple should change the consumption habit,because most of time things they buy are not they really want just as decoration or luxury.More stuffs means more trash.

Chinese 'facebook' friends hooked on games

This weekend I read a article about Chinese 'facebook'.I guess almost each chinese high school or college student has their own facebook,it's so popular among students.We can use it for communication and friends making.Here we can also find friends and ex-classmates whom you have lost contack with.Besides, you can get informed at first time of your ex-pats' latest news.
However,Chinese facebook is different from here. It has much recreational function.It hooks on games and various tests. One game was mentioned in this article.It's very interisting.And from this article we can see that Chinese facebook is most attractive than any other type of personal on-line space.
For me,I like face book much ,here I can know and be known much information of friends in China,although we are away now.It offers me much entertainment.I log on at least three times a day - in the morning, after lunch, and before I go to bed," he said. "Life is boring without it.
