     Some people may think too much sunlight can lead to cancer, so they always keep themselves away
from sunlight. But experts believe that proper exposure (暴露) to sunlight is good for us.
     For example, scientists think sunlight can help stop some diseases. They say that wearing sunscreen
(防晒油) all the time makes the body short of vitamin D.
     Vitamin D in fact stops us from more than 25 diseases and keeps bones and teeth healthy. However,
around 60% of the population are short of vitamin D in their blood. One of the easiest ways to get it is to
expose your skin to sunlight. Your body makes vitamin D from the sun faster than it takes in from food.
What"s more, safely getting enough sunlight can make you look younger.
     However, not everybody likes sunlight. Some people should not be exposed to the sun without a strong
sun protection. Experts advise that just ten minutes of daily exposure to sunlight should be enough to give
us vitamin D we need.

1. What does the passage mainly tell us?

A. Don"t expose to the sun.
B. Proper exposure to sunlight is good for our health.

2. What will happen if we don"t get enough sunlight for a long time?

A. We will keep away from cancer.
B. We will get many diseases.
C. Our body will be short of vitamin D.
D. We will have more vitamin D in our blood.

3. The proper sunshine can keep our _______ healthy.

A. eyes and skin
B. bones and teeth
C. ears and blood
D. bones and eyes

4. The underlined phrase"take in" in the passage means "_______" in Chinese.

     Soda is popular all over the world. People, especially young children, like drinking it very much because
it tastes good. Some of them drink at least one can or bottle every day. But drinking it not only costs too
much money, but also is bad for people"s health in some ways. If you drink too much soda, you will probably
become too fat, have a toothache. Even if you don"t mind your money, you must at least care about your health.
     Why is soda unhealthy? A study at a university has been made for years. It shows us how bad it is. First,
soda can lower your body"s PH levels. Second, soda can raise insulin levels (胰岛素水平), lead to high blood
pressure (血压), heart disease, weight gain and so on. Do you want your teeth to stop falling out? Stop
drinking soda! Do you want your bones (骨骼) to get harder? Stop drinking soda! Do you want to improve
your immune system (免疫系统)? Stop drinking soda! Do you want to lose weight? Stop drinking soda!
    But what should you drink instead? Water is good for your health. Drinking tea is a good idea, too. Anyhow, you should stop drinking soda from now on.

3. Soda can lower our body"s PH levels, _______ insulin levels, _______ high blood pressure, heart disease,
