Some people state they never forget a face. But what does that saying mean? Is there really no limit to the number of faces a person can remember?

A new study has found that, on average, people can remember as many as 5,000 faces. That number comes from a group of researchers at the University of York in England, There have been many studies recently on facial recognition. But the authors of this study say theirs is the first time that scientists have been able to put a number to the abilities of humans to recognize faces.

During the study, people spent one hour writing down as many faces from their personal lives as possible, Then, they wrote down famous faces they know, such as actors, politicians and other public people. The results showed that the participants knew between 1,000 and 10,000 faces, which is very shocking to the researchers. Rob Jenkins, coauthor of the study, said one explanation about it may be that some people have a natural ability for remembering faces. He also said it could be because of different social environments. Some people may have grown up in more populated places. So they may have had more social contact throughout their lives.

The ability to tell individual people apart is “clearly important.” In today’s modern world of big cities, televisions and social media, we meet thousands of people. Our facial recognition abilities help us to deal with the many different faces we see on the screens, as well as those we know.

The people in the study included 25 men and women. They are between 18 and 61 years old. “It would be interesting to see whether there is a peak age for the number of faces we know”, Jenkins said it is possible that we gather more faces throughout our lifetime. But, he added, there also may be an age at which we start to find it harder to remember all of those faces.

2.What does the underlined word “it” in Paragraph 3 refer to?

A. The difference of social environments.

C. The wide range of the numbers.

D. The necessity of facial recognition.

3.What will the researchers probably focus on after this study?

A. Why older people remember more faces.

B. When people can remember the most faces.

C. Whether people’s ability to remember faces is necessary.

D. How our ability to remember faces vary at different ages.
