二、阅读理解（每题3分，共30分）

Passage 1

A new study has found that people who drink coffee may have a lower risk of developing certain types of cancer. The study, which was conducted by researchers at the National Cancer Institute, looked at the coffee consumption habits of more than 400,000 people over a period of 10 years.

The researchers found that people who drank at least two cups of coffee a day had a lower risk of developing cancer of the liver, colon, and breast. The risk was reduced by about 20% for each cup of coffee consumed per day.

However, the study also found that drinking coffee did not have a significant effect on the risk of developing other types of cancer, such as lung cancer and prostate cancer.
