What do you usually do when you are free Do you often lie in the sofa, eat snacks and watch TV If you do like this, you are a “couch potato”. It means you spends too much time sitting on the sofa watching TV, playing video games, or using phones. Unluckily, more and more teenagers live this kind of life.
Scientists say that sitting for hours can lead to weight gain (导致体重增长) and have a pain in the back (后背疼痛). It can also cause (造成) eye problems. If people stare at (盯着) screens for a long time, their eyes will feel dry and tired. Teenagers always stay at home and they seldom go outside. They often talk less to their family and friends. They may have trouble in communicative skills and become ill in minds.
Parents and experts try to help children avoid forming (形成) this kind of lifestyle (生活方式). They should set time limits (设定时间限制). Teenagers can only watch TV or play computer games for one hour a day. Move your body, dance, play basketball for thirty minutes a day. Try some interests, such as reading books, drawing pictures or learning cooking.

5、炎德英才大联考(长郡版)长郡中学2027届高三检测(一)(27Y)政治答案
15.为了测量某凸透镜焦距,小华先在纸上画了一个小于透镜大小的圆环,如图所示,将凸透镜正对太阳光,在其下方距透镜8cm处的白纸上的光斑恰好与圆环重合,当将该透镜远离白纸垂直移动6cm时,此时白纸上的光斑再次与圆环重合,此过程中光斑的大小 (选填“先变小后变大”或“先变大后变小”),通过计算可以得到该凸透镜的焦距为 cm。
16.如图所示,虚线框内为一透镜,MN为透镜的主光轴,O是透镜光心,a(双箭头)和b(单箭头)是射向透镜的两条光线。已知光线a通过透镜之后与MN交于P点,光线b通过透镜之后与MN交于Q点。该透镜是 透镜,焦距 OQ(选填“大于”、“小于”或“等于”)。
三、实验探究题
17.在利用太阳光测量凸透镜的焦距后,小华将凸透镜正对着太阳,发现把火柴头放在凸透镜焦点处一段时间后,火柴会被点燃。他想进一步探究不同的透镜对火柴的点燃效果有什么不同,和同学们讨论后,他们提出了以下三种猜想:
猜想1:凹透镜也能点燃火柴;
猜想2:点燃火柴的快慢与凸透镜的焦距大小有关;
猜想3:点燃火柴的快慢与凸透镜的直径大小有关;
