Most people think a person’s taste in food is so unique and random that it couldn’t possibly reveal anything about his/her character.

But other subtle(奇妙的) things that people do can help us make up our mind about a person’s character. Should we really be so quick to dismiss what a person eats?

Dr. Alan Hirsch is a US neurologist (神经科医生) who specializes in the treatment of people who lose their sense of smell or taste.

In order to investigate the possible link between people’s choices of snack food and personality, Hirsch quizzed a sample of 19, 400 people. He made all participants undergo two well-known personality tests.

These tests define each of the volunteers according to widely accepted personality categories. Hirsch could then check his own results against these in order to find interrelation between their choice of snack food and personality type.

Hirsch also tested the volunteers on questionnaires designed to assess depression, because depressive illnesses are known to coincide with losses of sensation and preferences for certain foods.

The volunteers were then tested on their preference for snack foods and the pleasure value they assigned to each food. Hirsch also quizzed married partners on their choices to find out how people with different food choices differed in their compatibility (兼容性) for each other.

The study revealed surprising links between perfectionism and the urges to chew tortilla (玉米饼) chips and even a connection between introversion (内向) and the consumption of cream crackers.

Dr. Hirsch used the same technique of testing for associations between different personality types and the flavors of ice cream people prefer.

Finally, while some will feel this test provides a good assessment of their personality, others will disagree with the assessment.

Most Americans believe that someone isn’t grown-up until the age of 26 and they should complete their education, have a full-time job, have a family to support and be financially independent. They also believe that becoming a real grown-up is a process which begins at about the age of 20 and takes about five years, according to the report from the University of Chicago’s National Opinion Research Center.
The findings are based on a representative sample of 1,398 people over the age of 18 who were surveyed in person. The survey found that people expect the transitions to grown-up status to be completed at the following ages: age 20.9 self-supporting; age 21.1 no longer living with parents; age 21.2 having a full-time job; age 22.3 education completed; age 24.5 being able to support a family financially; age 25.7 getting married; and age 26.2 having a child.
“There is a large degree of agreement across social groups on the relative importance of the seven transitions,” said Tom Smith, director of the survey. The only obvious pattern of differences is on views about supporting a family, having children and getting married. Older adults consider these more important than younger adults do. This probably shows in large part a change in values across generations away from traditional family values. The most valued step toward reaching adulthood, the survey found, is completing education, followed by full-time employment, supporting a family, financial independence, living independently, and marriage.

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 a four-hourly feeding schedule will make a baby satisfied. The first of the experts to advocate a strict clock-watching schedule was Dr Frederic Truby King who was against feeding in the night. I've never heard anything so ridiculous. 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 rigid 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. Feeling 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 feeling practices.

A．He is strict

B．He is unkind

C．He has the wrong idea.

D．He sets a timetable for mothers

3.What does the research tell us about feeling a baby on demand?

A．The baby will sleep well.

B．The baby will have its brain harmed.

C．The baby will have a low blood sugar level.

D．The baby will grow to be wiser by the age of 8.

4.The author supports feeling the baby_______.

A．in the night

Visitors to Britain may find the best place to sample local culture is in a traditional pub. But these friendly pubs can be dangerous places of potential gaffes (失礼) for the newcomers. A team of researchers have discovered some of the unknown customs of British pubs-starting with the difficulty of getting a drink. Most pubs have no waiters-you have to go to the bar to buy drinks. A group of Italian youths waiting 45 minutes before they realized they would have to fetch their own. This may sound inconvenient, but there is a hidden purpose.

Pub culture is designed to promote sociability (社交) in a society known for its reserve. Standing at the bar for service allows you to chat with others waiting to be served. The bar counter is possibly the only site in the British Isles in which friendly conversation with strangers is considered entirely suitable and really quite normal behavior. “If you haven't been to a pub, you haven't been to Britain.” This tip can be found in a booklet, Passport to the Pub: The Tourists' Guide to Pub Etiquette, a customers' rule of conduct for those wanting to sample “a central part of British life and culture”．

The trouble is that if you do not follow the local rules, the experience may fall flat. For example, if you are in a big group, it is best if only one or two people go to buy the drinks. Nothing annoys the regular customers and bar staff more than a group of strangers blocking all access to the bar while they chat and hesitate about what to order.

1. The underlined word “sample” in the first paragraph probably means “________”．

A．taste

B．experience

C．test

D．record ．

2.The culture of pub in Britain is so developed to ______.

A．encourage people to communicate with each other

B．encourage more people to consume drinks

C．attract more tourists to the pubs

D．form its own character of culture

3.If you don't follow the local rules in a pub, ________.

A．you won't buy good local drinks

B．you may annoy the regular customers and bar staff

C．you may fail to feel the local culture

D．you might get into a dangerous place

4.What may be the best title for the passage?

A．Self-service Pubs in Britain	B．British Local Pubs: Special Chat Places
C．Local Pub Culture in Britain	D．Manners in British Local Pubs

We produce 500 billion of plastic bags in a year worldwide and they are thrown away polluting oceans, killing wildlife and getting dumped in landfills where they take up to 1,000 years to decompose. Researchers have been unsuccessfully looking for a solution.

The 16-year-old Canadian high school student, Daniel Burd, from Waterloo Collegiate Institute, has-discovered a way to make plastic bags degrade(降解) in as few as 3 months, a finding that won him first prize at the Canada Wide Science Fair, a ＄10,000 prize, a ＄20,000 scholarship, and a chance to revolutionize a major environmental issue.

Burd’s strategy was simple: Since plastic does eventually degrade, it must be eaten by microorganisms (微生物). If those microorganisms could be identified, we could put them to work eating the plastic much faster than under normal conditions.

With this goal in mind, he grounded plastic bags into a powder and concocted(调制) a solution of household chemicals, yeast(酵母) and tap water to encourage microbes growth. Then he added the plastic powder and let the microbes work their magic for 3 months. Finally, he tested the resulting bacterial culture on plastic bags, exposing one plastic sample to dead bacteria as a control. Sure enough, the plastic exposed to the live bacteria was 17% lighter than the control after six weeks.

The inputs are cheap, maintaining the required temperature takes little energy because microbes produce heat as they work, and the only outputs are water and tiny levels of carbon dioxide.

“Almost every week I have to do chores and when I open the closet door, I have piles of plastic bags falling on top of me. One day, I got tired of it and I wanted to know what other people are doing with these plastic bags. The answer: not much. So I decided to do something myself.” Said Daniel Burd.

C. he found a way to degrade plastics in shorter time

D. he could encourage microbe growth in an easier way

2. Daniel Burd exposed one plastic sample to dead bacteria to .

A. make the live bacteria work better B. test how effective his method was

C. know which bacteria worked faster D. control the temperature in the process

Maintaining the required temperature takes little energy because .

A. plastics can get hot easily B. microbes can produce heat themselves

C. much carbon dioxide is produced D. the temperature can be controlled

4. Daniel Burd got his idea from .

A. his school textbook B. the failure of researchers
