4.Even if allowed, we must also pay attetion to safety. 这句不是不好,而是如果这样接下去,就会很怪,你前面说的是在周末时玩的好处,现在有突然有even《即使》这词,那就成了:即使如果给,也要注意安全。这就跟前面的文字语气不相符。还有即使《even》=如果《if》,不能出现在同一句子。so, it can change to:If our parents allowed us to have the spare time, we will be very thank for it,but we need pay attention of the safety too,or we'll be hurt.
