　　Part I Reading Comprehension (30%)

　　Directions: There are three passages in this part. Each passage is followed

by some questions or unfinished statements. For each of them there are four

choices marked A, B, C and D, You should decide on the best choice and blacken

the corresponding letter on the Answer Sheet.

　　Passage 1

　　Questions 1 to 5 are based on the following passage:

　　Babies who are breast-fed may be more likely to be successful in life, a

new study published Tuesday suggests. The study followed more than 3,000 babies

into adulthood in Brazil. The researchers found those who were breast-fed

scored slightly higher in intelligence tests in their 30s, stayed in school

longer and earned more money than those who were given formula（配方奶粉）.

　　“Breast-feeding not only has short-term benefits, but also breast-feeding

has long-term benefits, "says Bernardo Lessa Horta of the Federal University of

Pelotas in Brazil, who led the study being published in The Lancet Global

Health.

　　(76) Doctors have long known that breast-feeding can be good for a baby’s

health. This is especially true in poor countries, where water can be

contaminated. For instance, a baby given formula in developing countries is 14

times more likely to die in the first six months than one who’s breast-fed. In

the U.S., some research has suggested that breast-feeding may raise a baby’s

IQ（智商）by a few points. But a recent study with siblings（兄弟姐妹）found

little advantage to breast-feeding.

　　Horta says these previous studies didn’t follow children into adulthood to

see if breast-feeding had long-term effects. So Horta analyzed data collected

from 3,493 volunteers he and his colleagues have been following since birth.

They are now in their 30s. First, the researchers gave the subjects IQ tests.

Those who were breast-fed for 12 months or more had IQ test scores that were

3.76 points higher than those who were breast-fed for less than one month, the

team found.
