B、一个正常中学生的质量约50kg-60kg之间，所以其体重大约是500N-600N，所以B是错误的；
C、正常人步行的速度是1.1m/s，所以C选项中的速度太大，即该选项也是错误的；

Directions: Read the following passage. Fill in the numbered blanks by using the information from the passage Write NO MORE THAN THREE WORDS for each answer. People in the United States honor their parents with two special days: Mother’s Day, on the second Sunday in May, and Father’s Day, on the third Sunday in June. These days are set aside to show love and respect for parents. They raise their children and educate them to be responsible citizens. They give love and care. These two days offer a chance to think about the changing roles of mothers and fathers. More mothers now work outside the home. More fathers must help with child-care. These two special days are celebrated in many different ways. On Mother’s Day people wear carnations. A. red one stands for a living mother. A. white one shows that the mother is dead. Many people attend religious services（宗教仪式）to honor parents. It is also a day when people whose parents are dead visit their graves(坟). On these days, families get together at home and in restaurants. They often have outdoor BBQs for Father’s Day. These are days of fun and good feelings and memories. Another tradition is to give cards and gifts. Children make them in school. Many people make their own presents. These are valued more than the ones bought in stores. It is not the value of the gift that is important, but it is “the thought that counts”. Greeting card stores, florists, candy makers, bakeries, telephones companies and other stores do a lot of business during these holidays. 小题1:
