Chinese parents are being urged to pay more attention to their children's nutrition, after a study
revealed that unscientific ways of feeding babies and a lack of trace elements are the two biggest threats
to youngsters'health. Experts drew these conclusions from a two year study into the nutrition and health
situation of children under six in ten cities including Beijing, Shanghai and Guangzhou.
Started in 2003 by the China National Children's Center, the survey includes 8043 children, equally
divided between the sexes. It shows 37 percent of surveyed children have baby food earlier than the
recommended age of four to six months old, with another 35percent taking it later, which in return brings
about a nutrition difference as these children grow up. "Our children above four to six months old fall
behind foreign children in terms of their physical well?being," said Zhao Shunyi, head of the center. She
called on Chinese parents to pay more attention to their children's nutrition after they stop breast feeding
at six months old.
Trace elements
The survey also shows more than half of the children above six months old are deficient in five trace
elements which are crucial to their physical development-magnesium, copper, calcium, iron and zinc.
"Lack of zinc will lead to low level of intelligence," said Dou Xiaowei, vice director of the National Center
for Child Nutrition Quality Supervision and Testing. "Parents had better choose baby food with plentiful
trace elements, especially calcium, iron and zinc."
Zhao said, "The center is urging the government to strengthen child food production management by
revising related laws. Child food producers should be advised to market products with rich trace
elements."

任务型阅读。 Since many of you are planning to study at a college or university in this country, you may be curious to know what you usually do in a typical week, bow you can get along with your fellow students, and so on. These are the questions I want to discuss with you today. First, let's talk about what your weekly schedule will look like. No matter what your major may be, you can expect to spend between four and six hours a week for each class attending lectures. Lectures are usually in very large rooms because some courses such as introduction to sociology or economics often have as many as two or three hundred students, especially at large universities. In lectures, it's very important for you to take notes on what the professor says because the information in a lecture is often different from the information in your textbooks. Also, you can expect to have exam questions based on the lectures. So it isn't enough to just read your textbooks; you have to attend lectures as well. In a typical week you will also have a couple of hours of discussion for every class you take. The discussion section is a small group meeting usually with fewer than thirty students where you can ask questions about the lectures, the reading, and the homework. In large universities, graduate students, called teaching assistants, usually direct discussion sections. If your major is chemistry, or physics, or another science, you'll also have to spend several hours a week in the lab, or laboratory, doing experiments. This means that science majors spend more time in the classroom than non-science majors do. On the other hand, people who major in subjects like literature or history usually have to read and write more than science majors do. | ||||||||||

Six-month-old babies are strictly limited in what they can remember about the objects they
see in the world. If you hide several objects from babies, they will only remember one of those
objects. But a new study, which was published in an issue of Psychological Science, a journal
of the Association for Psychological Science, finds that when babies “forget” about an object,
not all is lost. Researchers used to think that babies less than two years old did not understand
than an object continues to exist when it is not in the baby’s view. But in the mid-1980s, new
ways of doing experiments with babies found that they do, if fact, know that objects don’t
disappear when they are not looking at them- a concept know as object permanence. But it
was still unknown what babies needed to remember about objects in order to remember their
existence.
Now Melissa Kibbe, of Johns Hopkins University, and Alan Leslie, of Rutgers University, are
working to figure out exactly what it is that babies remember about objects. For the new study,
they showed six-month-old babies two objects, a disk and a triangle. Then they hid the objects
behind small screens, first one shape, then the other. Earlier research has shown that young babies
can remember what was hidden most recently, but have more trouble remembering the first object
that was hidden. Once the shapes were hidden, they lifted the screen in front of the first object.
Sometimes they showed babies the shape that was hidden there originally, but sometimes it was
the other shape, and sometimes the object had vanished completely.
Psychologists measure how long babies look at something to see how surprised they are. In
Kibbe and Leslie’s study, babies weren’t particularly surprised to see that the shape hidden behind
the screen had changed, for example, from a triangle to a disk. But if the object was gone altogether,
the babies looked significantly longer, indicating surprise at an unexpected outcome. “This shows
that even though babies don’t remember the shape of the object, they know that it should continue
to exist,” Kibbe says. “They remember the object without remembering the features that identify that
object.”
This helps explain how the young brain processes information about objects, Leslie says. He
thinks the brain has a structure that acts like a kind of pointer, a mental finger that points at an object.
