阅读理解
阅读下列短文，根据短文内容回答问题。
If you’re like most people, you probably think that you’re a pretty good judge of character. After all, you’ve spent a lot of time getting to know your friends and family members, right? But according to research, we’re not as good at reading people as we think we are.
A recent study from the University of Michigan found that people are often influenced by their first impressions when they meet someone new. In other words, we tend to form opinions about people based on how they look and what they say, rather than on who they really are.
The researchers asked participants to spend a few minutes getting to know someone new. Then, they had to answer questions about the person’s character. The results showed that the participants’ answers were often influenced by their first impressions. For example, if the person they met had a friendly smile and seemed outgoing, the participants were more likely to say that the person was trustworthy and reliable.
So, what can we do to improve our ability to read people? The researchers suggest that we take the time to really get to know someone before we make judgments about them. It’s important to listen to what they say and watch how they act. By doing this, we can get a better understanding of who they really are.
What is the main idea of the passage? 答案：The passage mainly discusses how we judge people and the influence of first impressions on our judgments.
According to the study, what do people usually base their opinions on when they meet someone new? 答案：People usually base their opinions on how the person looks and what they say.
What do the researchers suggest we do to improve our ability to read people? 答案：The researchers suggest that we take the time to really get to know someone before we make judgments about them.
