【小题1】What do we know about the kids who like asking questions?

Do you like drinking Coke? As a symbol of American culture, Coca-Cola is liked by many people, especially young people all around the world. But from now on, perhaps it will be hard for students in the US to get it on campus. A new agreement will end almost all sales of high-sugar fizzy drinks in US schools. The agreement allows only unsweetened juice, low-fat milk and water in primary and middle school vending machines（自动售货机）and cafeterias. Former American president Bill Clinton helped the American Heart Association and the beverage industry（饮料业） to come up with the agreement. He suffered from a weight problem and has had a heart operation since leaving the White House. He takes the agreement as “a bold step forward in the struggle to help 35 million young people lead healthier lives”.
Rising childhood obesity（肥胖）has become a big problem in America. A federal report noted that obesity has tripled among teenagers in the past 25 years. It called for new limits on the marketing of junk food to children. Soda is a particular target because of its caloric content and popularity among children.
Britain has already taken similar steps to fight obesity. A recent study shows that people in the UK are much healthier than the people in the US. However, it’s better late than never. Now American schools are trying to make new rules to guide the students to choose healthy drinks. American schools say goodbye to Coca-Cola.
【小题1】What kind of beverage is NOT allowed to sell on campus?

Now I know that we black people are much more likely to have high blood pressure and diabetes (糖尿病) than white people. And they often lead to heart attacks and other untreated diseases. For example, black people are three to four times more likely than white people to have high blood pressure and twice as likely as the white population to die of a stroke (中风).
New research has found out the surprisingly high levels of salt in many of black people’s favorite meals. I stopped putting extra salt in my food at the table long ago and I try to cut down on the salt. I use in cooking. The suggested daily level of salt for adults is 6 grams. It is easy to see that if you try not to eat too many processed (加工过的) foods and use salt in your cooking within the limit, you won’t reach more than the daily level.
The research showed how much salt there is in some foods that we buy from restaurants and takeaways. An average salad with rice and peas has 6.2 grams of salt. This is more salt than you are supposed to eat for the whole day.
A researcher talked about the importance of home cooking rather than take-outs. At home, he pointed out, not only can you hold control of the salt bottle, but also you can create tasty food which is low on salt. The researcher later provided curry goat and rice and peas. They were low on salt, but completely delicious.
I do not suppose Jamaicans are going to stop buying takeaways soon. But if you suffer from high blood pressure, it is probably better not to buy them often.
