Problems
A
B
C
My problem is my parents. They never stop going on about how I should keep my room tidy, keep my hair tidy and wear smart clothes. They even make me do the washing-up after dinner every night! None of my friends have got such terrible parents. What should I do?
Helen
My best friend has suddenly turned her back on me and I don’t know why! Last week we phoned each other every day and e-mailed too, and over the weekend we went shopping together and she was fine. But at school on Monday morning she didn’t look at me or speak to me. I don’t know what I’ve done. She now spends all her time with another group of friends.
Jane
I have a really bad habit of chewing(嚼)the ends of my hair. I try to stop, but I can’t! My mom is starting to get really angry about it. Have you got any ideas?
Gina
 
Advice
Hi _________,
Why should your parents do all the washing-up? You should help around the house—it’s only fair. I don’t think you should change your looks though. Young people should look like young people.
②Hi_________,
Wearing your hair pulled back in a ponytail(马尾辫)will help keep it out of your mouth. When you feel like chewing something, try bubble gum(泡泡糖). Give yourself time and you should be able to break this habit. The first few days are usually the hardest. Good luck!
③Hi ________,
Don’t worry about it so much! Phone your friend up as usual and she won’t be able to refuse you. I am sure you will get along well with each other. Everything will be fine.

Antifreeze is a liquid(液体) that is added to water to keep it from freezing. When water freezes and turns to ice,it expands(膨胀).The force of water expanding is so great that it will break the hardest metal.Water is used in car engines(发动机) to keep them cool while they run,and if this water is allowed to freeze in winter it can break the iron block of the engine.That is why antifreeze is necessary.
Water freezes at 0℃;the usual kind of antifreeze will not freeze until the temperature is-40℃.A mixture(混合物) of five parts of water and four parts of antifreeze will prevent freezing at-18℃;four parts of water and five parts of antifreeze reduce this to -22℃.
Alcohol is a kind of good antifreeze,but when the air is running it becomes hot and the alcohol boils away,so it must be changed very often.Most people use antifreeze that does not boil away when the engine is running.There are several chemicals that do this.One of the most popular is called ethylene glycol.
