阅读理解题为6-10题，请按顺序作答。阅读理解：Directions：Read the following passages carefully. Each passage is followed by some questions or unfinished sentences. For each of them there are four choices marked A, B, C, and D. Choose the best answer to each question.　　Do you ever automatically say “God bless you” when someone sneezes (打喷嚏)? Did you ever cross your fingers when making a wish? Most people who do these things never think about why they do them. They just do them.　　But there is a reason. Both acts are meant to insure good luck. They are superstitions that have come down to us from an earlier time, when everybody believed in good and devil spirits. Even in our modern world, when men are traveling to the moon, we are still practicing some of these ancient habits in our daily lives.　　In ancient times, men believed that the soul lived in the head. Every time when someone sneezed, he was risking the danger of forcing that soul out and blowing it out of the nose into the outside world. So, as protection against a lost soul, people would say “God bless you” to be sure that God would catch the soul and return it to its rightful owner.　　Similarly, in earlier times, men felt that the cross was a lucky sign. The point where the two lines of a cross met was the luckiest spot, for if you made a wish on this spot, the wish would be held between these two lines and not get loose. So, people crossed their fingers when they made a wish. A wish bound forever in this way would eventually have to come true.　　Moreover, since the evil spirits stood on the left, and the good spirits on the right, the right side was always considered the lucky side of the body. Putting your best foot forward meant starting out on the lucky side, with your right foot first. That was a guarantee of good luck at whatever you were about to do. We still speak of “putting your best foot forward,” although we don’t always start walking with the right foot.　　Each of these little good-luck habits once had a serious purpose. Although people no longer believe in evil spirits, they are still crossing their fingers or putting their best foot forward – just to be sure that good luck comes their way.To make a wish come true, you should ________.
