Yes, they are.CTeenager Jake Denham was skiing(滑雪) with his family in the USA when he fell over and lost one of his skis. His family didn't know that he had a problem. They kept on skiing. When they got to the foot of the mountain, there was no sign of Jake.Jake couldn't find his ski anywhere. In the end, he decided to take off his other ski and walk down the mountain. But he couldn't work out the right way to go.It was now getting dark and he was a long way from any place of safety. He knew that he might die that night in the cold temperatures. But Jake kept calm(镇定)．At home, Jake watched a lot of TV programmes about living in difficult situations. He remembered the advice from these programmes and knew that he should build a hole in the snow. He made a hole and pointed it up the hill so the wind couldn't blow into it. Outside his hole, the temperature fell to a dangerous 15℃that night, but inside it Jake was safe from the cold.But he had to get down the mountain. The TV programmes always said，“If you are lost, you should find someone else's tracks (足迹) through the snow and follow them.” “I wanted to live my life，” remembers Jake.“So I got up and I found some ski tracks and I followed those.” He walked and walked and finally he saw lights. Nine hours after he lost his ski, he found a team of workers who came to save him. He was safe!His mum was very happy when she heard the news. Amazingly, Jake didn't even have to go to hospital. He got through the terrible experience without any injuries.So, the next time someone says that watching TV is a waste of time, think of Jake. Sometimes TV can save your life!36．Jake's parents didn't know that he was missing until ________.A．they reached the foot of the mountainB．they began to ski down the mountainC．a team of workers found JakeD．Jake lost one of his skis37．What was the most important decision Jake made for his safety?A．To go skiing with his family in the USA.B．To search for the ski that he had lost in the snow.C．To take off his other ski and walk down the mountain.D．To build a hole in the snow to keep himself warm.38．How did Jake get down the mountain the next morning?A．He followed his parents.

When was the last time you showed your family members that you care for them? Your relationships with friends，family members and teachers show a lot about the kind of person you are.♦Face the fears about the futureNow，imagine that one of your good friends told you that he or she was not strong enough togo back to school.We__often__give__better__advice__than__we__are__willing__to__take__ourselves.(43) Remember that even the most successful people were probably told that what they wanted to do was impossible，but they followed their dreams and succeeded.♦Develop your talentsIf you want to reach your goals，you will have to spend more time developing the talents you already have，and uncovering any hidden talents that you haven't discovered yet. So you can take classes in subjects that you are interested in，even if you have no experience.♦Be thankfulTake some time to be thankful for the things you do have. Remember positive memories.Think__of__the__best__day(s)__you__have__had__in__the__past__month__or__year.(44)Remember special parties，vacations and holidays.
