According to a recent study in the Journal of Consumer Research, both the size and consumption habits of our eating companions can influence our food intake. And contrary to existing research that says you should avoid eating with heavier people who order large portions(份), it's the beanpoles with big appetites you really need to avoid.

To test the effect of social influence on eating habits, the researchers conducted two experiments. In the first, 95 undergraduate women were individually invited into a lab to ostensibly(表面上)participate in a study about movie viewership. Before the film began, each woman was asked to help herself to a snack. An actor hired by the researchers grabbed her food first. In her natural state, the actor weighed 105 pounds. But in half the cases she wore a specially designed fat suit which increased her weight to 180 pounds.

Both the fat and thin versions of the actor took a large amount of food. The participants followed suit, taking more food than they normally would have. However, they took significantly more when the actor was thin.

For the second test, in one case the thin actor took two pieces of candy from the snack bowls. In the other case, she took 30 pieces. The results were similar to the first test: the participants followed suit but took significantly more candy when the thin actor took 30 pieces.

The tests show that the social environment is extremely influential when we're making decisions. If this fellow participant is going to eat more, so will I. Call it the “I’ll have what she's having” effect. However, we'll adjust the influence. If an overweight person is having a large portion, I'll hold back a bit because I see the results of his eating habits. But if a thin person eats a lot, I'll follow suit. If he can eat much and keep slim, why can't I?

1.What is the recent study mainly about?

A.Food safety. B.Movie viewership.

C.Consumer demand. D.Eating behavior.

2.What does the underlined word “beanpoles” in paragraph 1 refer to?

A.Big eaters. B.Overweight persons.

C.Picky eaters. D.Tall thin persons.

3.Why did the researchers hire the actor?

A.To see how she would affect the participants.

B.To test if the participants could recognize her.

C.To find out what she would do in the two tests.

D.To study why she could keep her weight down.

4.On what basis do we “adjust the influence” according to the last paragraph?

A.How hungry we are. B.How slim we want to be.

C.How we perceive others. D.How we feel about the food.

In effect, many people avoid the very attempts that are the source of true happiness. They fear the pain inevitably brought by such things as marriage, raising children, professional achievement, religious commitment and self-improvement.

Ask a bachelor (单身汉) why he resists marriage even though he finds dating less and less satisfying. If he is honest he will tell you that he is afraid of making a commitment. For commitment is in fact quite painful. The single life is filled with fun, adventure and excitement. Marriage has such moments, but they are not its most distinguishing features.

Couples with infant children are lucky to get a whole night's sleep or a three-day vacation. I don't know any parent who would choose the word fun to describe raising children. But couples who decide not to have children never know the joys of watching a child grow up or of playing with a grandchild.

Understanding and accepting that true happiness has nothing to do with fun is one of the most liberating realizations. It liberates time: now we can devote more hours to activities that can genuinely increase our happiness. It liberates money: buying that new car or those fancy clothes that will do nothing to increase our happiness now seems pointless. And it liberates us from envy: we now understand that all those who are always having so much fun actually may not be happy at all.

1.According to the author, a bachelor resists marriage chiefly because _______ .

A.he is unwilling to take family responsibilities

B.he believes that life will be more cheerful if he remains single

C.he finds more fun in dating than in marriage

D.he fears it will put an end to all his fun adventure and excitement

2.Raising children, in the author's opinion, is _______ .

A.a moral duty B.a thankless job

C.a rewarding task D.a source of inevitable pain

3.To understand what true happiness is one must _______ .

A.have as much fun as possible during one's lifetime

B.make every effort to liberate oneself from pain

C.put up with pain under all circumstances

D.be able to distinguish happiness from fun

4.What is the author trying to tell us?

A.Happiness often goes hand in hand with pain.

B.One must know how to make money.

C.It is not important to make commitments.

D.It’s pain that leads to happiness.

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(决定) 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.

1.What did Richard Axel and Linda Buck find out?

A. The type of food smells.

B. The logical part of human brain.

C. The nature of human olfactory system.

D. The relationship between food and feelings.

2.Which of the following can help people concentrate?

A. Bread. B. Fast food.

C. Pizza. D. Coffee.

3.What do we know from the last paragraph?

A. Different people are sensitive to different smells.

B. Every person has a different pattern of genes.

C. Some people can recognize up to 50 smells.

D. There are still some olfactory genes to be found out.

4.What is the passage mainly about?

A. Logic and behavior. B. Smell and its influence.

C. Sense ability and food tastes. D. Olfactory genes and its system.

Plants do not listen to the radio. But a team of researchers in Greece recently found a way to turn lemons into very small “radio stations” that can broadcast information about their trees’ moisture content to a smartphone—the first step toward creating what the researchers call an “Internet of plants.”

Scientists had previously attached sensors to trees to measure their water use, but “no other team had created a wireless radio network among plants, sending information while consuming only a few microwatts and costing just a few dollars,” says project leader Aggelos Bletsas, a professor of electrical and computer engineering at the Technical University of Crete.

The network consists of several basic components: an existing FM radio station, an antenna (天线) attached to a lemon growing on a tree, a humidity (湿度) sensor in the lemon, a transistor connected to an antenna and an FM receiver. First, the antenna picks up the signal from the FM station, and then passes the signal to the transistor, which is modulated by the humidity sensor. The sensor switches the transistor on and off at a rate dependent on the plant’s moisture level: if the soil is wet or if the atmosphere is humid, that rate is lower; if it is dry, the rate is higher. Finally, the antenna broadcasts this information to the radio receiver on a mobile phone.

In this way, plants can tell farmers if they are thirsty. “We can literally ‘listen’ to the moisture of the plant, using our mobile FM radio with a $3.4 sensor,” Bletsas says. “Two of these sensors for every acre on any given farm might change the way we conduct agriculture and ‘understand’ plants.” He notes that more sensors may be needed for the best possible results. Such real-time information could enable better control of air and soil moisture.

Why go through all this trouble and not just use already common wireless technology, such as Bluetooth? “Not only is our technique less complex, as we are just borrowing signals in the environment,” Bletsas says, but “a Bluetooth-based sensor costs about $25. Our final aim is to launch sensors onto the market costing less than $1.”

“Bletsas and his team are completely changing the way of environmental sensing using very simple equipment and surprisingly little power,” says Alexandros Dimakis, an associate professor of electrical and computer engineering at the University of Texas at Austin, who was not involved in the research. “Their work could be a transformational Internet of Things technology for agriculture and for monitoring the environment.”

Bletsas and his colleagues have already applied for a patent for their innovative technology in America.

1.The radio network created by Greek researchers _________.

A.consumes much energy

B.can be put in a smartphone

C.uses simple technology at low cost

D.broadcasts radio programs to plants

2.What does the underlined word “modulated” in Paragraph 3 mean?

A.Monitored. B.Adjusted.

C.Measured. D.Connected.

3.What is Alexandros Dimakis’ attitude to the “radio network”?

A.Positive. B.Critical.

C.Neutral. D.Doubtful.

4.What is the purpose of the passage?

A.To discuss methods of studying plants.

B.To assess the efficiency of Internet of plants.

C.To stress the importance of keeping soil’s moisture.

D.To introduce a new way of measuring plants’ water use.

Recently, researchers at the University of Toronto figured out a way with a quick video selfie to accurately measure blood pressure with your smartphone’s camera by developing a technology known as transdermal optical imaging (TOI)(透皮光学成像).

Cameras on smartphones can catch red light reflected from hemoglobin (血红素）under our skin, which permits TOI to visualize and measure blood flow changes. Researchers measured the blood pressure of 1,328 Canadian and Chinese adults by getting two-minute videos of their faces on an iPhone. “From the video got by the technology, you can see how the blood flows in different parts of the face and through this flow, you can get a lot of information,” said Kang Lee, lead author of the study.

Lee also helped create an app called Anura, which allows people to try out the TOI software for themselves, giving them the ability to record a 30-second video of their face and receive measurements for stress levels and resting heart rate. Lee said more research was needed to make sure that the measurements were as accurate as possible, explaining that the study didn’t test people with very dark or very fair skin.

“In order to improve our app to make it usable, particularly for people with hypertension (高血压)，we need to collect a lot of data from them, which is very hard because a lot of them are already taking medicine,” Lee explained. “We cannot tell them not to take medicine, but from time to time, we get participants who don’t take medicine so we can get hypertensive people this way.”

The scientists said there were many potential applications of the technology, including providing health services for those who lived in remote areas.

1.What is mainly talked about in Paragraph 2？

A.Information offered by TOI. B.New findings on hypertension.

C.How TOI is put into smart phones. D.How the TOI technology works.

2.What might people benefit from the new technology mentioned above?

A.Living a life free from stress. B.Improving the heart function gradually.

C.Accessing health services for free. D.Knowing abnormal blood pressure earlier.

3.What can be done for a better Anura?

A.Equipping phones with better cameras.

B.Allowing phones to record longer videos.

C.Collecting data from more diverse samples.

D.Persuading participants not to take medicine.

4.Why does the author write this text?

A.To predict future applications of TOI.

B.To introduce TOI and an app related.

C.To describe functions of cameras on phones.

D.To evaluate the quality of an app called Anura.
