Children who are brought up by two parents grow up to be cleverer than those raised by just one person, new research suggests. Being with both parents in the earliest years of life leads to a child developing more brain cells, the scientists believe. Being brought up by both parents causes boys to have better memory and learning functions. By contrast, it causes girls to develop improved co-ordination and sociability.

It is believed that babies with two parents tend to get more attention and more stability(稳定), and that they are less likely to suffer emotional distress(悲伤) in the first years of life. This leads to greater brain cell production ------ for boys it is grey matter brain cells that develop and for girls is white matter brain cells.

The researchers from Canada studied mice and experimented by creating one-parent and two-parent family groups. They then measured the offspring’s(后代的) brain cell development from birth to adulthood. Adult mice with the highest number of brain cells turned out to be those who had been brought up by two parents rather than one. As babies they had received more attention and more nursing as both parents took turns to lick and tend to their youngsters, said Dr Samuel Weiss.

As a result, the babies with two parents are less likely to suffer early life hurt which can have a massive impact on how their brains develop in later life, the research shows. However, what did surprise the researchers is that female babies who grew up with both parents turned out to be good single mothers, as if good parenting was passed on.

The researchers said,“ In the mouse model, parenting and the environment directly impacted adult brain cell production. It is possible that similar effects could be seen in other mammals, such as humans.”

A Bite of China, featuring delicious Chinese food, has attracted countless viewers, and moved many to tears.

A Bite of China is a serious documentary providing a unique view of Chinese as well as the relations between people and food and between people and society from the view of food. The touching documentary reminds some people of their mother, and makes some realize that every grain comes from hard and laborious work. Some people see patriotism(爱国精神) in the documentary, and some consider it a great cultural export.

How did this documentary achieve a great influence beyond its subject matter in such a short time?

“It is not empty propaganda(宣传) about China’s splendid food culture. Instead, it shows the techniques used in making food and their production process as well as the lives of ordinary people, thus striking a chord(共鸣) with the audience,” an Internet user said. The success of the documentary should be owed to sincerity and reality. Nowadays, many works of art that have high investment, high technology, and magnificent scenes lack nothing but sincerity and reality.

A Bite of China shows that a commercial documentary promoting patriotism can be full of touching details, that the emotions of ordinary Chinese people should be exhibited even in publicizing(宣传) China overseas, and that even a completely commercial program can achieve both artistic and commercial success.

“We made this documentary with our respect and love for food,” said director Chen Xiaoqing. Being sincere is the most important thing for artists because they cannot move others unless they themselves are first moved, and cannot convince others unless they themselves are first convinced. Sincerity is the “secret” for making this documentary so popular, and every cultural creator should learn from its success.

   A. a book            B. a film          C. a newspaper        D. a TV program

   B. Different people can get different messages from the documentary.

   C. The documentary should have shown China’s splendid food culture.
