    What makes a group smart and able to solve problems successfully and make good solutions? Oh, we may ask: what makes a group intelligent? A group’s IQ (智商), we might think, would be simply the average intelligence of the group members, or perhaps the intelligence of the smartest group member. But some scientists have found that this isn’t so.

A group’s intelligence comes out from communications（交流） within the group. A group’s intelligence can be calculated, and like the IQ grades of a single person, and it can predict the group’s performance on lots of kinds of tasks perfectly. A single person’s intelligence can be trained to develop, so can a group’s intelligence. Here are some suggestions on how to guide the development of smart groups:

Personally, you can choose group members carefully. The smartest groups are made of people who are good at reading each other’s social signs. And then it’s better for you to talk about the “how”. Groups who take the time to discuss how they will work together are more well-organized and successful.

As a group member, it is also very important for you to share the information in the formal meetings. The members who just control the discussion or who stay away and don’t say much make the intelligence of the group lower. But in the smart group, members connect directly with each other, not just with group leader. They always take an active part in every small conversation that could be added to main discussion. Outside of formal meetings, the smartest groups spend a lot of time communicating, too. All members can have a coffee break at the same time, leading them to do their work more professionally and feel more pleased with their jobs.

The main idea of the passage	A group’s 1. is from communications among the group members.
Features（特征） of the group’s IQ	--- We can 2. the group’s intelligence ---Its IQ grades can be decided and known. --- It can predict the group’s performance. --- It can be developed by being3., too.
4. on how to develop the IQ of smart groups	--- Group members should have good communication skills. ---Each group member should have the same chance to exchange 5. in the formal meetings. --- Group members should be active in small conversations and information meetings.
