     Tina, Mike, Jeff, Linda和Vera在生活、學(xué)習(xí)和運(yùn)動(dòng)中遇到一些問(wèn)題，請(qǐng)閱讀下面五個(gè)片段（1-5），并從后面的選項(xiàng)（A-E）中幫他們找到解決問(wèn)題的方法或建議。

(     )1. Tina has been invited to one of her friends’ birthday party next Sunday. She is worried about this
now because she has never taken part in any birthday party, and nobody can tell her something about it.
(     )2. Mike’s favorite is playing sports. He gets up early at 6:00 every morning. Then he goes out to
exercise by the riverside. He runs along the river for nearly half an hour, and then takes a walk for a few
minutes. He goes back home for breakfast at 7:30. But he always feels weak after morning exercises.
(     )3. Jeff is interested in the computer. His parents bought him a Dell computer last month. He wants to
surf the Internet. But he heard that there are many terrible things for kids on the Internet. His parents don’t have the knowledge about this.
(     )4. Linda’s parents will be away for China on business for more than half a year very soon. She can’t
go with them because she has to go to school. She will be at home alone. Nobody will take care of her,
and she can’t do chores herself.
(     )5. Vera is a clever girl. She does well in her studies.But Vera doesn’t like playing with her classmates, and she feels bored when her classmates ask her questions about studies. So she can’t get along well with her classmates.

A   Don’t give your personal information such as your address, telephone number, etc. on the Internet without your parents’ permission. Never agree to get together with someone you “meet” online and never send a person your picture or anything else without first checking with your parents.
B   On the day of the party, make sure you arrive on time and show that you’re happy to be there. Wear
something suitable. Greet your friend with a “Happy Birthday” and hand over the gift. Make sure you have put a card with your name on it.
C   Always smile, so people don’t think you are serious and hard to get along with. Be polite and modest. If you are rude, people will not like you. If people have troubles, you help them. Then, when you have
troubles, they will help you, too.
D   Parents should get the kids to do their chores around the house. If their clothes need washing, they wash them themselves. Let the kids prepare their own meals. Let them clean their room, cook for themselves, wash the dishes, etc.
E   Let’s say that the last time you eat something at night is at 6 or 7 pm (just an example). The following
day, you don’t eat breakfast but wait until you finish sports - you’ve gone many hours with nothing in your stomach. Your body has to work hard.It’s not good.What’s more, consider reducing the time and strength of your morning exercises.
