"Hi son, how was your day? I'm so tired. Today was a hard day. Hi dad, I'm fine. I'm doing my homework. I need your help. Oh, again?
Not now, please. I'm really tired. I want to sleep a little." "Dad, please. I need to deliver（投递） this homework tomorrow morning. Come on. Okay（好）, okay（好）.
But your questions are always very weird（怪异的）. Anyway（ 不管怎样）, let's do it. Thank you dad. Why do the kids（小孩） next door have so many more toys（玩具） than I do?" "Seriously（严重地）? Is that your question? Do you want me to buy you more toys?" "No, dad. It's just a question. I want to know, please.
I need to understand. Alright（ 好）, well, it's up to adults to decide what they do with their money. And our neighbors may（可能） choose to spend more on toys（玩具） than we do. It's easy to feel jealous（妒忌的）. But having more stuff（材料） won't make our family happier or better than any other." "I get it dad. Next question.
Why do people get sick? I want to know. Hmm, well, I think. Usually it's because of germs（微生物）. These tiny（微小的） craters（弹坑） can find their way into our body through the air we breathe（呼吸） and things we eat. Or when we touch（触摸） our mouth or eyes without washing our hands.
Be careful（仔细的）. Most of the time germs don't affect（影响） us, but sometimes our body can't find them off. And that's when we get sick. Occasionally（偶然） people also become ill（有病的） because their body isn't working（使工作） properly. But you can't catch（捉住） those kinds of sicknesses（疾病）. Fortunately（幸运地）, in most cases（情况）, resting（使休息） and taking medicine（内服药） can help your body heal（治愈）.
So don't worry（ 担忧） about that." "Plus, your dad and mom will always be here to take care（小心） of you son. So don't worry." "Thank you dad. Why aren't there any more dinosaurs? They are animals and... Well, about 65 million years ago an enormous（巨大的） asteroid（[天] 小行星） collided（碰撞） with the earth and changed everything on the planet. The dinosaurs couldn't adapt（使适应） and eventually（终于） died out."
"Making way for new animals. Ones that were better suited to this other climate（气候）."
