At the University of Kansas art museum, scientists tested the effect of different colored walls on two groups of visitors
to an exhibit of paintings. For the first group the room was painted white; for the second, dark brown. Movement of
each group was followed by an electrical equipment under the carpet. The experiment showed that those who entered
the dark brown walked more quickly, covered more area, and spent less time in the room than people in the white
one. Dark brown made people more active, but the activity ended sooner. Not only the choice of colors but also the
general appearance of a room affects those inside. Another experiment presented people with photographs of faces
whose energy was to be commented. Three groups of people were used; each was shown the same photos,
but each group was in an ordinary room—a nice office. The third was in a tastefully designed living room with
carpeting. Results showed that the people in the beautiful room tend to give higher marks to the faces than
those in the ugly room did. Other studies
that students do better on tests taken in comfortable room than in ordinary-looking or ugly rooms.

City life is not always a bad thing, but many experts worry about this process of urbanization (城市化 ). A new report says that process is having a huge effect on human health and the quality of the environment. Of the three billion people who live in cities now, the report says, about one billion live in unplanned settlements. These are areas of poverty, slums that generally lack basic services like clean water, or even permanent housing. More than 60 million people are added to cities and surrounding areas each year, mostly in slums in developing countries. The international community has been too slow to recognize the growth of urban poverty. Policy makers need to increase investments in education, health care and other areas.
The report talks about some successful efforts by local governments and community groups. For example, it says in Columbia, engineers have created a bus system that has helped reduce air pollution and improve quality of life.
The link between urban poverty and the environment is serious, but governments also need to consider why people are moving out of rural areas. Climate changes, droughts, floods—there are many reasons forcing people to leave their farm land.
The two issues of poverty reduction and the environment have existed side by side, but rarely have they connected—until now. Governments are starting to understand that environmental collapse is not a natural cost of economic development. Instead, it is hurting the possibility for growth.
The main idea of the passage is about ______.
A.urbanization and its effects
B.a huge effect of human
C.economic development
D.the environment
