　　Women who ate soy regularly as children have a lower risk of breast cancer, American researchers report. And men who eat fish several times a week have a lower risk of colon cancer, a second team of researchers have told the American Association for Cancer Research.

　　The studies add to a growing body of evidence about the role of diet in cancer. Cancer experts now believe that up to two-thirds of all cancers come from lifestyle factors such as smoking, diet and lack of exercise.

　　The US National Cancer Institute and researchers at the University of Hawaii found that women who ate the most soy-based foods, such as tofu and miso, when aged 5 to 11, reduced their risk of developing breast cancer by 58 per cent. It was not clear how soy might prevent cancer, though compounds in soy called isoflavones have estrogen-like effects.

　　A second study showed that men who ate fish at least five times a week had a 40 per cent lower risk of developing colorectal cancer compared with men who ate fish less than once a week.

　　Many kinds of fish are rich in omega-3 fatty acids, which interfere with the cyclooxygenase-2 or COX-2 enzyme. COX-2 affects inflammation, which may play a role in tumour growth.

　　good morning(afternoon), dear teachers and fellow students. it’s my greathonor to stand here and share with you a happy morning(afternoon). i am no__. mytopic is “keep your goal in mind” .i hope you will enjoy it.

　　do you have a goal for your work? do you have a goal for your study? do youhave a goal for your life? maybe i will get an affirmative reply. yeah, everyonehas a goal of doing something. there is no doubt that a goal is very importantin our life. now i want to tell you a true story in my school life. i havelearned a lot from it.

　　i never forget last year’s school sports meeting. 1500-meter race was oneof the most exciting. before the race, my best friend xiaoshan had a goal to beno. 1. as a matter a fact, she is not so strong, but she is a sunny girl. she isactive and likes doing sports. what’s more, she tries her best to achieve thegoal, but i wonder if she is able to be the champion. there were eight playersin the race. on the first lap, she was in the sixth place; on the second lap,the took the fourth place, she went on running and she ran toward her goal, thegoal in her mind, look! on the last lap, she was the first to pass the finishingline, she was the winner. oh, great! she made it! congratulations!

　　at that time, i knew a goal was so necessary and important. i made adecision : “i want to take part in the english speaking competition held in myschool. what’s more, i will try my best to be no.1 in the competition as my bestfriend xiaoshan did in sports meet. ” i am sure of it. i still remembered whatmy english teacher said to us. he said :“if anyone took the first place in ourschool english speaking competition, he or she will be chose to take thecompetition held in jinjiang. it’s a great honor!”

　　though i can do well in my english written exams, however, to be honest, iam a little afraid to speak english in public. my english teacher oftenencourages me: “raoning, your voice sounds so beautiful, be brave, you willsucceed.” from then on, i kept a goal in mind. i said to myself aloud: stick toyour goal and you will win. and then i try my best to improve my oral englishand dare to speak either in class or after class. at last, i took part in thecompetition and became no. 1. i am chose to take part in the next year’s englishspeaking competition held in jinjiang. i said to myself aloud again: come on!you will win.

　　how time flies! today i am a lucky dog. i am very honored to give you aspeech. i hope everyone has a dream! in fact, we should work hard to make ourdream come true. otherwise it will become day dream. at the same time, i hopeeveryone has a goal in mind, because the goal is the first step to success. comeon, my friends, goal, goal, goal, success, success, success!
