Complete the following sentence with a (compound) word derived from the one(s) given in bracket.
It is obvious that if you are（ ）and friendly to people you will get a lot more back. (consider)
【正确答案】：CONSIDERATE
【题目解析】：
本题考查的是常见动词的形容词。
由“and friendly”可知，空缺处同样应填形容词。consider的用于人的形容词形式是considerate意为“考虑周到的”（另一形式considerable意为相当大的）。
句意：很明显的是，如果你对他人考虑周到和友好的话，别人也会这样对你。
