Do you often drink fruit juice and think it is good for your health? However，a recent study published in a US medical journal(期刊)shows that drinking too much juice—even 100 percent natural fruit juice—will increase your risk of early death. 1. According to scientists，drinking too much fruit juice is just like drinking too much soda(苏打汽水)—they both have a lot of sugar. Taking in too much sugar can cause many health problems，such as weight problems，heart disease and so on. 2. But the amount is too small to make up for the harm that these drinks do.
In the study，"sugary drinks" were defined(定义)to include both sugar-sweetened(添加糖的)drinks like soda and 100 percent natural fruit juice. Scientists found that if people get 10 percent or more of their energy from sugary drinks every day，they will be 44 percent more likely to die from heart disease. 3. As Jean Welsh，one of the researchers in the study，told CNN，"Sugary drinks，whether soft drinks or fruit juice，should be limited(限制)." 4. In this way，fewer people will buy sugary drinks because of their higher prices.
But how much is acceptable? Here are the suggestions from scientists. 5. Adults and children older than 6 should not drink more than 230 ml every day.
A. Also，they are 14 percent more likely to die from other diseases.
B. That is why some cities in the US have increased prices of sugary drinks.
C. This is mainly because these drinks have a lot of sugar.
D. Kids always like something sweet.
E. Kids between 1 and 6 years old should drink less than 170 ml of fruit juice every day.
F. When people eat sugar-sweetened food，they can feel happy.
G. Some people might say there are also vitamins(维生素)in fruit juice.

Passage 9
1. C 根据“However, a recent study published in a US medical journal(期刊) shows that drinking too much juice—even 100 - percent natural fruit juice—will increase your risk of early death.”可知，美国一项研究表明喝太多果汁会增加早逝的风险，所以设空处应讲述原因。选项 C“这主要是因为这些饮料含有大量的糖”符合语境。故选 C。
2. G 根据“But the amount is too small to make up for the harm that these drinks do.”可知，设空处提到了果汁中含有的某种有益成分。选项 G“有些人可能会说果汁里也有维生素”符合语境。故选 G。
3. A 根据“they will be 44 percent more likely to die from heart disease”可知，前文讲述死于心脏病的风险增加，此处顺承讲述其他疾病的风险，衔接上文，选项 A“此外，他们死于其他疾病的可能性高出 14%”符合语境。故选 A。
4. B 根据“In this way, fewer people will buy sugary drinks because of their higher prices.”可知，设空处提到含糖饮料价格的话题。选项 B“这就是为什么美国一些城市提高了含糖饮料的价格”符合语境。故选 B。
5. E 根据“Here are the suggestions from scientists. ... Adults and children older than 6 should not drink more than 230 ml every day.”可知，设空处介绍科学家分年龄给出的建议。选项 E“1 至 6 岁的儿童每天喝果汁的量应少于 170 毫升”符合语境。故选 E。

【解析】
1. C 根据前文“喝太多果汁会增加早逝风险”，设空处应解释原因，选项C“这主要是因为这些饮料含有大量的糖”符合语境。
2. G 根据后文“但（有益成分的）含量太少，无法弥补这些饮料造成的伤害”，可知设空处提到果汁中的有益成分，选项G“有些人可能会说果汁里也有维生素”符合语境。
3. A 根据前文“死于心脏病的可能性增加44%”，此处应顺承介绍其他疾病的风险，选项A“此外，他们死于其他疾病的可能性高出14%”符合语境。
4. B 根据后文“通过这种方式，因为价格更高，买含糖饮料的人会更少”，可知设空处提及含糖饮料涨价的内容，选项B“这就是为什么美国一些城市提高了含糖饮料的价格”符合语境。
5. E 根据前文“科学家的建议”及后文“6岁以上儿童和成人每天不超过230毫升”，可知设空处是针对低龄儿童的建议，选项E“1至6岁的儿童每天喝果汁的量应少于170毫升”符合语境。

Cooking，the art and science of preparing food，is far more than daily housework. It's like a fun classroom where you can learn different subjects all at once! 1.
Science is everywhere in cooking. When you make bread，the yeast(酵母)eats sugar and makes bubbles of gas. 2. When you cook meat and it turns brown and smells good，that's cool chemistry. Also，think about heating water，which shows how heat moves. It is all about physics.
3. You need to follow the instructions when you mix materials，like "adding 1/4 spoon of salt". Sometimes you have to make some changes to feed more or fewer people. That means doing math. Even buying the required materials at a low cost teaches you math.
Food has a lot of history. Each food has its own origin and development. Spices(香料)were once traded like gold，and this changed how countries talked to each other. 4. In hot places，people grow more different foods than in cold places. Learning about these things helps you understand how the world works.
Cooking is like a secret key that opens the door to learning many subjects. It's not just about making yummy food. 5. Schools should teach cooking because it helps students see how everything in learning is connected!
A. Geography also matters.
B. This is biology in action.
C. Math helps a lot in the kitchen.
D. Cooking avoids wasting money.
E. It's also about becoming smarter in lots of ways.
F. Some students often spend money buying ready-made food.
G. The following will explain why cooking should be taught at school.
