However, a healthy diet can reduce your risk of developing the disease by 40 to 60 percent. Generally speaking, eating more vegetables can reduce your risk of developing breast cancer by 60 percent. Vegetables like cabbage are rich in fiber (纤维), can lower your risk of developing breast cancer. To get the most from their goodness, it’s recommended that you eat at least three to four cups of these vegetables per week. It’s the oleic acid (油酸) contained in olive oil. American scientists conducting laboratory research have observed that oleic acid has a beneficial effect on breast cancer cells. Olive oil is the richest source of this acid, so whenever possible, use it in place of butter. Eating fruit is another excellent way to help prevent the development of breast cancer. In fact, women who do eat fruit are six percent less likely to develop the disease. The American Institute for Cancer Research considers berries (浆果类) (blueberries, strawberries, etc.) to be powerful for breast cancer fighters. It’s the lycopene (番茄红素), found in great quantities in tomatoes, that can reduce the risk of developing breast cancer. The lycopene found in canned tomatoes is more readily absorbed by the body than that contained in fresh ones, so add tomato juice, paste, and sauce to your diet. As a result of various studies, the American Institute for Cancer Research has concluded that components (成分) found in green tea can help halt the development of cancerous tumours (瘤) and even prevent them from appearing in the first place. Three cups a day will help you get the benefits of green tea. 小题1:What does the author mainly tell us?How to cure breast cancer by eating healthy foods.Healthy diets help fight against breast cancer.Proper fruits, vegetables and drinks keep you fit.Breast cancer is the most terrible killer for women.小题2:We learn from the passage that ________.eating more fruit and vegetables can stop your risk of developing cancerolive oil can help breast cancer cells developwomen eating tomatoes won’t suffer from breast cancercomponents found in green tea can reduce the risk of developing cancer小题3:What does the underlined word "halt"in the last paragraph mean?A. stopB. increaseC. changeD. pull 小题4:According to the passage, the author may agree that ________.A．Ten percent of women suffer from breast cancerB．Berries are the richest source of the oleic acidC．The lycopene found in olive oil has a good effect on breast cancer cellsD．Drinking green tea properly can help you keep healthy
