     In the early 1950s, researchers found that people scored lower in intelligence tests if they could speak more than one language.    1   So which one of them is right? There is a new finding recently.

Researchers showed their latest studies at a meeting in February, 2011. The latest evidence shows that

being bilingual(双语的)does not necessarily make people smarter.    2   .

    Imagine you are driving down the highway. There are many things that could draw your attention and

you really need to be able to notice all of them.    3   Why? The answer is that bilingual people are often

better at controlling their attention.

    The best method to measure it is called the Stroop Test. A person is shown words in different colors.

The person needs to tell the colors of the words.    4   For example, the word  "blue" might be written in

red, but you have to say red. You need to ignore the word and pay more attention to its color so that

you can say correctly. The bilingual people continually practise this function because both languages are

active in their mind at the same time.

        5   Researchers say bilingual children are better able to separate a word from its meaning and are

more likely to have friends from different cultures. Bilingual adults are often four to five years later than

others in suffering from dementia (痴呆症). 

A. This would be easier if you are bilingual.

B. The problem is that the words are all names of colors.

C. This would be very difficult for them to achieve.

D. However, another research in the 1960s showed the opposite.

E. They would be cleverer than other people.

F. In addition, it might help people in other ways, too.

G. But researchers say it probably does make people better at certain skills.
