1Answer the questions (根据短文内容回答下列问题)

I’ve always wanted to try rock climbing, but never had time or money for it. But I’ve discovered a way to experience the thrill(兴奋,紧张) of climbing rock. Indoor climbing is an easy and exciting way to get a taste of rock climbing. And it is also much cheaper and safer! Indoor climbers don’t climb on real rock, but on a plastic wall. You can probably find a climbing wall near you. Many gyms,

schools and camps have one.

You can climb in doors at any time of the year, no matter how the whether is. It is usually not expensive. Most gyms provide the equipment you need. The convenience of indoor climbing is one reason why it has become so popular. But the main reason people climb is for rush(刺激感) they get. When I stand at the roof of the wall and look up, I’m always scared, but once I start climbing, fear changes to determination. With my heart pounding(心剧烈跳动), I reach the top and look down. I can’t stop grinning. I did it! Indoor climbing is a great workout(锻炼). Climbing uses muscles(肌肉)that are hard to exercise, especially those in the shoulders, arms, chest and back. Many people say climbing makes exercise fun. Most gyms have several climbing walls with various degrees of difficulty. The easier ones are like climbing a ladder. The difficult ones bulge out(凸出)in places so that climbers must sometimes climb parallel(平行的)with the floor.

Although gym climbing is easier and safer than real rock climbing, you should still be careful. Always climb with a partner. As you climb, your partner pulls you climbing rope through something called a belay device(绳索控制器). The belay catches you if you slip. But make sure your partner knows how to use this equipment. And if you are a first-time climber, get some instruction before you begin.

1.Is indoor climbing cheaper and safer than real rock climbing?

2.On what do indoor climbers climb?

3.What are the reasons that make the indoor climbing so popular?

4.Who should always be with you when you climb?

5.What does your partner do as you climb?

6.Which do you think sounds more fun, rock climbing or indoor climbing? Why?

Why should we learn to swim?
Firstly, swimming is a good exercise for our health. Indeed doctors say it is the best exercise, because in swimming all the muscles of the body are used.
Secondly, swimming gives great pleasure. How nice it is, on a hot dusty day in summer, to take off one’s clothes and dive into the cool water of a rive or the sea, and to swim and float until one feels enough.
Thirdly, swimming may sometimes mean all the different between life and death, we never know when we may be in danger from water. We got on a voyage, and the ship in wrecked; we go for a pleasure sail on a lake and the boat turns over; we slip as we are walking along the bank of a river, and half in the water. If we can swim, we have chance for saving our own lives, but if we cannot swim, we are pretty certain to be drowned. So for our own safety, we should learn to swim.
