1     Tim caught a cold yesterday because of the weather change. Now he’s got a bad cough and a running nose. He feels cold even in bed.

    2     Joanna always gets a toothache because she eats candies very often. What’s more, she doesn’t like brushing her teeth.

    3     Lisa spends most of her time working with computers. So she often feels uncomfortable and rubs (揉) her eyes.

    4     Jack is often busy with work. He never cares when to eat and what to eat. So he gets a stomachache twice a week.

    5     Michael is a delivery (投递) man. Every day, he needs to carry many heavy products. As time goes by, he has a sore back.

A. Do not eat too many sweets. You should brush your teeth at least twice a day. After you finish your meal every time, you’d better rinse your mouth (漱口).

B. Take some medicine. Drink plenty of water. And take a good rest. Remember to wear warm clothes when it is cold. Exercise every day to make yourself strong.

C. Lie down and have a rest when you feel pain in your back. And you’d better take an X-ray to see how serious it is.

D. Have some warm milk before bed. It can help you relax. Try not to stay up late. A hot shower can also help.

E. You’d better have a stomach check-up. Learn to form a healthy eating habit and look after yourself. You should eat hot food and have three meals on time.

F. Do not eat spicy and salty food. They are not good for your throat. You should also drink water as much as possible. Try to speak as little as possible.

G. Doing eye exercises can help you feel comfortable. Don’t use computers for hours, and remember to rest your eyes every half an hour.
