You may think that sailing is a difficult sport, but it is really not hard to learn it. You do not need to be strong. But you need to be quick. And you need to understand a few basic rules about the wind.

First, you must ask yourself, “Where is the wind coming from? Is it coming from ahead or behind or from the side?” You must think about this all the time on the boat. The wind direction tells you what to do with the sail.

Let’s start with the wind blowing from the behind. This means the wind and the boat are going in the same direction. Then you must always keep the sail outside the boat. It should be at a 90° angle (角度) to the boat. Then it will catch the wind best.

If the wind is blowing from the side, it is blowing across the boat. In this case, you must keep the sail half way outside the boat. It should be at a 45° angle to the boat. It needs to be out far enough to catch the wind, but it shouldn’t flap (摆动). It shouldn’t look like on a flagpole. If it is flapping, it is probably out too far, and the boat will slow down.

Sailing into the wind is not possible. If you try, the sail will flap and the boat will stop. You may want to go in that direction. It is possible, but you can’t go in a straight line. You must go first in one direction and then in another. This is called tacking. When you are tacking, you must always keep the sail inside the boat.

小题1:What should you consider first while sailing?

A.Sailors’ strength.

B.Wave levels.

C.Wind directions.

D.Size of sails.小题2:What does the word “It” underlined in Paragraph 4 refer to?

A.The boat.

B.The wind.

C.The sail.

D.The angle.小题3:What do you have to do when sailing against the wind?

A.Move in a straight line.

B.Allow the sail to flap.

C.Lower the sail.

D.Tack the boat.小题4:Where can you probably find the text?

A.In a popular magazine.

B.In a tourist guidebook.

C.In a physics textbook.

D.In an official report.

1999年5月1日,B公司向A公司订购价值6万元的黄桃。合同规定:A公司在 1999年6月前向B公司交付30吨黄桃,每吨价格2000元;B公司则应于1999年5月上旬先付款50%,其余货款在B公司收到黄桃后10日内付清。1999年5月5日,B公司付款3万元给A公司,1999年6月15日A公司将黄桃送至B公司,B公司收货后,认为黄桃不符合合同约定的质量要求,致函A公司要求减少价款,A公司收到信后回函否认。1999年7月因市场上黄桃需求量不大,而黄桃又不宜长时间保存,B公司就将黄桃进行了降价处理。1999年9月20日,A公司派人到B公司索要剩余3万元货款,B公司说黄桃质量不合乎合同要求,要求减少价款。A公司不同意,双方当时各执己见,协商没有结果。后来因为A公司管理层变更,一直未再向B公司提出清偿货款的请求。2001年,A公司在清理债权债务时发现存在此笔款项,于是于2001年7月5日向某市区人民法院起诉要求B公司清偿剩余3万元价款并赔偿损失。B公司则以原告的诉讼请求已过诉讼时效为由抗辩。 问题:

原告A公司提起诉讼之后,对诉讼时效发生何种法律效力
