三、阅读理解
阅读下面短文，从每题所给的 A、B、C、D 四个选项中选出最佳选项。
About once a year, someone in my family gets the flu, and soon, everyone catches it. It is something many families go through.
But another thing can spread(传播) in a family even more often: moods(心情). Studies show this. A person's bad mood can impact us. It spreads just like the flu.
I always find it hard to control my mood. Small things like my favourite sports team losing will make me upset. And my bad mood will spread to everyone around me. Here's how it works: our bad moods can make others talk about their own bad experiences, making things even worse.
Life can be difficult. We all have bad days at school or hear bad news. It is natural to be unhappy sometimes. But the worst thing we do is to bring our bad moods home to our loved ones. Bad moods, even small ones, can make a big difference. They can make everyone upset.
Positivity(积极性) can lead to good results. When someone is positive, he can make everyone happy. So control what you can and try to spread positivity. It feels great to be a little sun around your friends and family!
