3. The supervision of students is relatively weak and the sense of learning scenes is low.养成一个好男人，需要良好的家庭教育外，爱情是进阶的必要课程。男孩在爱情里受了伤，于是一点一滴的成熟为一个男人，但那慢慢愈合大的痂大多是丑陋的，它教育了男人怎麽用自私武装自己的恐惧、以名利成就自己的筹码。有一种幸运的男孩，他会遇到生命中的贵人，那贵人往往是一位「好姊姊」。关于那些好姊妹教他们的事，是实战的、非教条的、生动而且造就了一段美丽的回忆。/grovel (party)At that tail of the warhead, the drag armour-piercing firebomb is filled with a drag agent and a fireagent, Under the pressure of propellant propelling warhead, it will spontaneously ignite to produce open flame, So it can break through the oil drum and ignite or detonate the gasoline. However, the old-fashioned traced armour-piercing firebombs have obvious trajectories due to traced light when they are launched. Therefore, it is very easy to expose oneself while pointing targets to friendly forces. Therefore, the new tracer armour-piercing firebombs now equipped all start to burn and emit light only after the projectile flies out of the muzzle for a certain distance (the generally set safe distance is 100 meters, which makes it impossible for the enemy to judge the firing position with tracer ammunition, while targets within 100 meters do not need to be indicated by tracer), The principle is generally to ignite the tracer and combustion agent carried by the projectile by accumulating the heat generated by the warhead's friction with the air after flying for a certain distance to a certain extent.后面还会不会发生那么多事，那他们如今又会是怎样的呢？先前那两个衣衫破烂的小子就是小葱跟秦淼装扮的。
