【题目】 Researchers continue to show the power behind our sense of smell. Recent studies have found, among other things, that the smell of foods like pizza can cause uncontrollable anger in drivers on roads.

The review explains that smell is unique in its effects on the brain. According to Conrad King, the researcher who carried out the review, "more than any other senses, the sense of smell goes through the logical part of the brain and acts on the systems concerned with feelings. This is why the smell of baking bread can destroy the best intentions of a dieter."

Smell, which dictates the unbelievable complexity of food tastes, has always been the least understood of our senses. Our noses are able to detect up to 10,000 distinct smells. Our ability to smell and taste this extremely large range of smells is controlled by something like 1,000 genes (基因), which make up an amazing 3% of the human genome. Researchers Richard Axel and Linda Buck were together awarded a Nobel Prize in 2004 for their ground-breaking research on the nature of this extraordinary sense. These two scientists were the first to describe the family of 1,000 olfactory (嗅觉) genes and to explain how our olfactory system works.

According to one study in the research review, smelling fresh pizza or even the packaging of fast foods can be enough to make drivers feel impatient with other road users. They are then more likely to speed and experience uncontrollable anger on roads. The most reasonable explanation is that these can all make drivers feel hungry, and therefore desperate to satisfy their appetites.

In contrast, the smells of peppermint and cinnamon were shown to improve concentration levels as well as reduce drivers’ impatience. Similarly, the smells of lemon and coffee appeared to promote clear thinking and mental focus.

However, the way genes regulate smell differs from person to person. A study by researchers in Israel has identified at least 50 olfactory genes which are switched on in some people and not in others. They believe this may explain why some of us love some smells and tastes while others hate them. The Israel researchers say their study shows that nearly every human being shows a different pattern of active and inactive smell-detecting receptors.

【题目】 Growing up, Deka Ismail says she let labels define what she could be. “I was a black girl, from a refugee (难民) family,” Deka said. “It was as if I was only allowed to explore in this predetermined box.”

After a high school chemistry class inspired her to think about a career in science and gave her confidence in the field, Deka learned to live outside labels and began making big plans for her future. Now she is about to begin her freshman year at the University of California, planning to become a professor.

Born and raised in San Diego’s City Heights neighbourhood, Deka is the daughter of a Somali refugee couple. While some might say Deka’s success happened in spite of her background, she would say differently, that her experiences shaped her and inspired her to be the driven, young scientist that she is today.

When Deka was eight years old, her mother got a job by studying hard back in school in order to support the whole family. That made Deka realize that education could make a difference to one’s life. She spent a lot of time in the library reading books, and didn’t do many of the things her peers did, like partying or having romantic relationships.

“I always felt like I had to be the perfect girl for my family,” Deka said. “You have to not even do your best but two times better than everyone else. I felt like the whole world was waiting for me to mess up.”

Deka’s efforts paid off. The summer before her senior year of high school, she was accepted to the American Chemical Society Project SEED Programme. “She brought both enthusiasm and focus,” Botham, a researcher at this research institute, recalled. “She arrived every day ready to work, ready to learn and ready to tackle new challenges regardless of whether or not she had done anything similar.”

When asked what advice she would give to others like her, Deka warned them not to underestimate themselves. “Don’t tell yourself that scholarship is too big or this programme is too competitive or I’ll never get into this school, ” she said. “I was not sure whether I could make it until I started seeing the acceptance letters rolling in.”

1From the passage, we can learn that ______.

A.Deka was adopted by a refugee family

B.Deka spent a lot of time going to parties

C.Deka became a professor after graduation

D.Deka’s experiences drove her to work hard

2Deka realized the importance of education ______.

A.from her mother’s experienceB.after her chemistry class

C.by reading books in the libraryD.through working at the institute

3According to the last paragraph, Deka advised that students be ______.

A.patientB.confident

C.ambitiousD.generous

4What does the story intend to tell us?

A.Life is not all roses.

B.Practice makes perfect.

C.Well begun is half done.

D.Hard work leads to success.

【题目】 Teenagers are often a difficult group.With all those hormones(荷尔蒙)flooding in their bodiesthey can be moodyunpredictableand tend to make uncertain choices.But however confusing their teenage years arekids can still be generally happydepending on their lifestyle choices.According to a new research by British scientiststeens who don't smokedrink only moderately(适度地) or not at alland who don't eat much junk food are likely to be happier than other teens.

The study looked at 40,000 British families and came up with some interesting findings.For examplekids who never drank alcohol were up to six times more likely to report higher levels of happiness than kids who drank.And teens who smoked were five times less likely to rate high on happiness charts compared to kids who didn't smoke.The same goes for diet and physical activities.The more fruits and vegetables kids eatand the more hours they spend playing sportsthe happier they are.

Nowof course this doesn't mean that not smoking or drinkingand playing sports can guarantee happiness.It could be that kids who have happy character tend to be more active and less addicted to drinking or smoking.And it could equally be the case that kids who are unhappy are more related to drinkingsmoking and eating junk food.

Other studies have shown that exercise is a proven way to treat anxiety and depression. Future studies may support the idea that other healthy behaviorsincluding refraining(克制)from smokingdrinkingand eating too much junk foodcan avoid sadness and increase happinesstoo.

1The author develops the second paragraph mainly by________.

A.making comparisonsB.providing statistics

C.offering examplesD.analyzing causes

2What can we learn from the text

A.Not smoking or drinking guarantees happiness.

B.Teens with flooding hormones cannot be happy.

C.Playing sports can decrease teens' unhappiness.

D.Unhappiness can certainly lead to smoking and drinking.

3Which can be the best title for the text

A.Ways to treat anxiety and depression

B.Exercise and teenagers' health

C.Teenagers shouldn't drink or smoke

D.Teenagers' lifestyle and their happiness

【题目】Money Matters
