已知金属导体的电阻会随着温度的降低而减小，当温度降低到一定程度时，电阻会减小到零，这就是超导现象．现在有一个灯泡，在刚点亮的一段时间内，它的电阻会______（选“变大”、“变小”或“不变”，下同）；它消耗的功率将______．
当灯泡刚点亮的一段时间内，温度会升高，所以电阻会变大，通过灯泡的电流会减小，根据P=UI即可得出，消耗的功率会变小．
故答案为：变大，变小
任务型阅读，每空一词 There are different outdoor activities for different seasons. In spring we can fly kites .In summer, we can go swimming or sailing. In autumn, It is a good idea to camp or hike. In winter, we can go to ski or skate they bring us a lot of fun .they make us strong and fit, too. So it is important for people of all ages to take part in some outdoor activities at the right time.

Young people like exciting activities ,like diving（潜水）, skiing and horse riding. Children like fun activities like flying kites . Some outdoor activities are dangerous, like climbing rocks.
