I have been consistently opposed to feeding a baby regularly. As a doctor, mother and scientist in child development, I believe there is nothing to recommend it, from the baby’s point of view.

Mothers, doctors and nurse alike have no idea of where a baby’s blood sugar level lies. All we know is that a low level is harmful to brain development and makes a baby easily annoyed. In this state, the baby is difficult to calm down and sleep is impossible. The baby asks for attention by crying and searching for food with its mouth.

It is not just unkind but also dangerous to say that a four-hourly feeding schedule will make a baby satisfied. The first of the experts to advocate (提倡) a strict clock-watching schedule was Dr Frederic Truby King, who was against feeding in the night. I’ve never heard anything so silly. Baby feeding shouldn’t follow a timetable set by the mum. What is important is feeding a baby in the best way, though it may cause some inconvenience in the first few weeks.

Well, at last we have copper-bottomed research that supports demand feeding and points out the weaknesses of strictly timed feeding. The research finds out that babies who are fed on demand do better at school at age 5, 7, 11 and 14, than babies fed according to the clock. By the age of 8, their IQ(智商)scores are four to five percent higher than babies fed by a strict timetable. This Research comes from Oxford and Essex University using a sample(样本)of 10,419 children born in the early 1990s, taking account of parental education, family income, a child’s sex and age, the mother’s health and feeling style. These results don’t surprise me. Feeding according to schedule runs the risk of harming the rapidly growing brain by taking no account of sinking blood sugar levels. I hope this research will put an end to advocating strictly timed baby feeding practices.

People from East Asia tend to have more difficulty than those from Europe in distinguishing facial expressions---and a new report published online in Current Biology explains why.

Rachael Jack, University of Glasgow researcher, said that rather than scanning evenly across a face as Westerners do, Easterners fix their attention on the eyes.

“We show that Easterners and Westerners look at different face features to read facial expressions,” Jack said. “Westerners look at the eyes and the mouth in equal measure, while Easterners favor the eyes and ignore the mouth.”

According to Jack and her colleagues, the discovery shows that human communication of emotion is more complex than previously believed. As a result, facial expressions that had been considered universally recognizable cannot be used reliably to convey emotion in cross-cultural situations.

The researchers studied cultural differences in the recognition of facial expressions by recording the facial movements of 13 Western people and 13 Eastern people while they observed pictures of expressive faces and put them into categories: happy, sad, surprised, fearful, disgusted, or angry. They compared how accurately participants read those facial expressions using their particular eye movement strategies.

It turned out that Easterners focused much greater attention on the eyes and made significantly more errors than Westerners did. “The cultural difference in eye movements that they show is probably a reflection of cultural difference in facial expressions,” Jack said. “Our data suggest that while Westerners use the whole face to convey emotion, Easterners use the eyes more and mouth less.”

In short, the data show that facial expressions are not universal signals of human emotion. From here on, examining how cultural factors have diversified these basic social skills will help our understanding of human emotion. Otherwise, when it comes to communicating emotions across cultures, Easterners and Westerners will find themselves lost in translation.

1.The discovery shows that Westerners______.

A. pay equal attention to the eyes and the mouth

3.What does the underlined word “they” in paragraph 6 refer to?

A. The participants in the study

B. The researchers of the study

C. The errors made in the study

D. The data collected from the study

4.In comparison with the Westerners, Easterners are likely to_____.

A. do translation more successfully

C. examine the eyes more attentively

D. read facial expressions more correctly

WHAT’S the most important thing of life?

People’s answers vary greatly. For British scientist Robert Edwards,the answer is having a child.“Nothing is more special than a child,”he told the BBC.

Edwards,the inventor of the In Vitro Fertilization(IVF)technology—more commonly known as“test?tube(试管)baby”technology—passed away on April 10 ,2013 at the age of 87.

Edwards changed the lives of millions of ordinary people who now rejoice(充满喜悦)in the gift of their own child,”said Peter Braude,professor at King’s College London.“He leaves the world a much better place.”

Edwards started his experiments as early as the 1950s,when he had just finished his PhD in genetics. At that time,much of the public viewed test-tube babies as“scary”,according to Mark Sauer,professor at Columbia University,US.

Edwards and his colleague Patrick Steptoe faced opposition from churches,governments and media,not to mention attacks from many of their fellow scientists.“People said that we should not play God and we should not interfere with nature,”Edwards once told Times. He said that he felt “quite alone” at the time.

“But Edwards was a fighter,and he believed in what he was doing,”said Sauer. Without support from the government,the two struggled to raise funds to carry on. And in 1968 they finally developed a method to successfully fertilize human eggs outside the body.

The first test-tube baby was born on July 25,1978.Her name was Louise Brown. Despite people’s safety concerns,Brown was just as healthy as other children.

“IVF had moved from vision to reality and a new era in medicine had begun,”BBC commented.

Ever since then,public opinion has evolved considerably. Couples who were unable to have babies began thronging(蜂拥)to Edwards’ clinic. Nowadays,Reuters reports,some 4.3 million other“test-tube” children exist. Edwards received a Nobel Prize in 2010 and was knighted(封为爵士)by Queen Elizabeth Ⅱ the following year.

Before his death,Edwards was still in touch with Louise.“He is like a granddad to me,”she said in an interview with the Daily Mail.

He is a granddad to millions, in fact.

(NEW YORK) A French tourist highly praised for rescuing a two-year-old girl in Manhattan said he didn’t think twice before diving into the freezing East River.

Tuesday’s Daily News said 29-year who left the spot quickly after the rescue last Saturday.

He lifted the little girl out of the water after she fell off the bank at the South Street Scaport museum. He handed the girl to her father, David Anderson, who had dive in after him.

“I didn’t think at all,” Duret told the Daily News. “It happened very fast. I reacted very fast.”

Duret, an engineer on vacation ,was walking with his girlfriend along the pier(码头)when he saw something falling into the water .He thought it was a doll, but realized it was a child when he approached the river. In an instant, he took off his coat and jumped into the water.

When he reached the girl, she appeared lifeless, he said. Fortunately, when she was out of the water, she opened her eyes.

Anderson said his daughter slipped off the bank when he was adjusting his camera. An ambulance came later for her, said Duret, who was handed dry clothes from lookers. Duret caught a train with his girlfriend shortly after.

The rescue happened on the day before he left for France. Duret said he didn’t realize his tale of heroism he was leaving the next morning.

“I don’t really think I’m a hero,” said Duret. “Anyone would do the same thing.”

1.Why was Duret in New York?

A.To meet his girlfriend

B.To work as an engineer

C.To spend his holiday

D.To visit the Andersons

2.What did Duret do shortly after the ambulance came?

Since the 1970s, scientists have been searching for ways to link the brain with computers. Brain-computer interface(BCI) technology could help people with disabilities send commands to machines.

Recently, two researchers, Jose Milan and Michele Tavella from the Federal Polytechnic School in Lausanne, Switzerland, demonstrated a small robotic wheelchair directed by a person’s thoughts.

In the laboratory, Tavella operated the wheelchair just by thinking about moving his left or right band. He could even talk as he watched the vehicle and guided it with his thoughts.

“Our brain has billions of nerve cells. These send signals through the spinal cord (脊髓)to the muscles to give us the ability to move. But spinal cord injuries or other conditions can prevent these weak electrical signals from reaching the muscles,” Tavella says. “Our system allows disabled people to communicate with external world and also to control devices.”

The researchers designed a special cap for the user. This head cover picks up the signals from the scalp(头皮) and sends them to a computer. The computer interprets the signals and commands the motorized wheelchair. The wheelchair also has two cameras that identify objects in its path. They help the computer react to commands from the brain.

Prof. Milan, the team leader, says scientists keep improving the computer software that interprets brain signals and turns them into simple commands. “The practical possibilities that BCI technology offers to disabled people can be grouped in two categories: communication, and controlling devices. One example is this wheelchair.”

He says his team has set two goals. One is testing with real patients, so as to prove that this is a technology they can benefit from. And the other is to guarantee that they can use the technology over long periods of time.

A. By controlling his muscles.

B. By talking to the machine.

C. By moving his hand.

A. scalp→computer→cap→wheelchair

B. computer→cap→scalp→wheelchair

C. scalp→cap→computer→wheelchair

D. cap→computer→scalp→wheelchair

4. The team will test with real patients to ________.

A. make profits from them

B. prove the technology useful to them

C. make them live longer

D. learn about their physical condition

5.Which of the following would be the best title for the text?
