 Today, an increasing number of people are always looking at their mobile phones with their heads down. These people are called the “Heads-down Tribe(低头族)”. Are you a heads-down tribe member? Heads-down tribe members now can be seen everywhere.

 More and more traffic accidents are happening because more drivers use mobile phones when they are driving. In order to make drivers pay more attention to driving, some new traffic rules have been made. For example, people who use mobile phones while driving in Taiwan are fined (罚款).  Car drivers  and  motorcyclists  who  break  the traffic rule will be fined NT$3,000 and NT$1,000 respectively(分别地).

 As we can see above, using mobile phones may cause accidents and even cost a lot of money. Also, more and more interesting and strange facts happen to the “Heads-down Tribe”. Let's have a look at an interesting TV report. A man in America kept using his mobile phone on his way home.

 As a result, he knocked into a big lost bear. When he lifted his eyes from the phone,he was so afraid that he turned around and ran away quickly. Another fact is that we can often see people in the restaurant eating face to face but looking at their own mobile phones.  It's strange that they don't talk to the ones who sit opposite to them during the meal. Some of them even have fun communicating with others on the phone.

 Mobile phones are helpful and necessary tools for modern life. Are mobile phones good or bad? It depends on how people use them. Let's be “healthy”users and try to be the "Heads-up Tribe”.

Making Peace with Your Parents

    As a teen, you're going through big changes physically and mentally. Your interests are increasing.____Here is the challenge: Kids need to explore the world in new ways, and parents need to protect them from the dangers that are all out in that world. These conflicts can easily set off fireworks in otherwise calm houses. Sometimes conflicts can't be avoided. But by paying attention to the building blocks of successful relationships, you can work towards making home a happy and healthy place for you and your parents.

    For example, try to find a time to talk when your parents are not angry, tired, distracted or hungry. A good time to talk is when you're all relaxed. Timing is everything if the conversation begins to turn into an argument, you'd better calmly and coolly ask to stop the conversation for now.____ Listen to what your parents are saying, and repeat it back to them. This shows them that you're listening. ____ Respect is the building block of good communication. People who respect each other and care about each others' feelings can disagree without getting things ugly.____ How do you build trust? Trust comes by actually doing what you say you're going to do. Some teens find that doing fun activities with their parents can improve their relationships. Sometimes we forget that parents are more than rule-maker—they're interesting people who like to watch movies and go shopping—just like their teenagers!

    What do you do if you are trying your best, but your relationship with your parents continues to be rocky?____You can find supportive adults, such as a teacher or a coach, who can lend an ear. Remember you can only change your own behavior. Your parents are the only ones who can change theirs.

A. You may consider seeking outside help.

B. And then you'll be able to accept what your parents say.

C. You can pick it up again when everyone's more relaxed.

D. Faced with the challenge, children don't know what to do.

E. And your desire to take control of your own life is growing.

F. It also gives them a chance to clear things up if you're not on the same page.

G. You are more likely to get along with your parents and have more independence if your parents believe in you.
