Playing with toy blocks (积木) may lead to improved language development in young children, a new study reported.
Early childhood is an important period in the development of young minds. The newborn brain grows three times in size between birth and age 2. Scientists have said that certain activities during this important period may promote (促进) healthy development while others may hold it back, and development of memory and language may especially be helped by imaginative play.
After six months, language scores among half of the 175 children aged 1-1/2 to 2-1/2 who were sent plastic blocks were 15 percent higher than a matched group that did not receive the free blocks, according to the study by researchers at the University of Washington in Seattle.
Parents were given ideas about how to help their children play with the blocks, then were told to keep diaries of their children’s activities over four days. Finally, all the parents filled out questionnaires that judged their children’s vocabulary, grammar, and other language abilities. Study author Dimitri Christakis said unstructured play with blocks motivated children’s thinking, memory and physical skills at a time when a child’s brain is growing rapidly. “They are the foundation of thought and language,” he wrote of the skills learned from building blocks. “Older children begin to make up stories for these objects .”
Such play may also take the place of less helpful activities such as watching TV, he said, adding parents ought to have doubts about some toy-makers’ words. “An increasing number of media-based products are making ungrounded (无根据的) claims that they can make children smarter, more literate, and more musical,” Christakis said.

C.O.P.D(慢性障碍性肺病) blocks air flow through the lungs. It makes breathing difficult. The leading cause of C.O.P.D. is cigarette smoking. Experts at the National Institutes of Health in the United States say there is no cure to the damage to the lungs.
Dawn Demeo is an assistant professor at Harvard Medical School in Boston, Massachusetts. She said, “By 2020, C.O.P.D. may be the third leading cause of death across the world.”
C.O.P.D. is a new name for emphysema（肺气肿） and chronic bronchitis（慢性支气管炎）. These are the two most common forms of the disease. Many people with C.O.P.D. have both of them. And Doctor Demeo says more women than men now die from the disease.
She is the lead author of a study by a team from Harvard’s Brigham and Women’s Hospital and the University of Bergen in Norway. The new study adds to findings that women may be more at risk than men from the damaging effects of smoking.
The team examined results from a Norwegian study of 954 people with C.O.P.D. Inga-Cecilie Soerheim co-wrote the team’s findings. Doctor Soerheim says they show that women suffered the same level of C.O.P.D.as men. But the female smokers were younger and had smoked a lot less.
The team also looked at two groups among the people in the study. These were people under the age of 60 and those who had smoked for less than 20 years. In both cases, women had more serious C.O.P.D. and a greater loss of lung function (功能）than men.
小题1:Which of the following statements about C.O.P.D is NOT true ______.
A. Cigarette smoking is likely to cause C.O.P.D.
B. C.O.P.D. makes it hard for a person to breathe
C. C.O.P.D will be one of the most life-threatening diseases.
D. Many people with C.O.P.D. have either emphysema or chronic bronchitis.
小题2:It can be known from the study that_____.
A. female smokers die faster than male ones.
B. women are more likely to suffer from the damaging effects of smoking than men.
C. women who suffer the same level of C.O.P.D as men were older and weaker.
D. in the group of people under the age of 60, men suffered more from C.O.P.D than women.
小题3:Which of the following can be the best title for the passage?
A .Smoking Kills
B. Smoking Triggers Diseases
C. The Leading Causes of C.O.P.D.
D. Women Suffers More from C.O.P.D. than Men
小题4:In which part of a newspaper would you most probably read this passage?

A．Science

B．Health report

C．Education

D．Business report

Millions years ago much of our earth was covered with blocks (块) of ice. These ice blocks were as tall as high buildings in modern cities. Most of the ice was in the northern (北方的)part of the world.
