Children brought up on healthy diets are more intelligent compared with their junk food eating partners, a new research suggests.
Kids fed a diet packed high in fats, sugars, and processed(加工) foods had lower IQs than those fed pasta(意大利面食), salads and fruit, it was found.
The effect is so great that researchers from the University of Bristol said those children with a “healthier” diet may get an IQ improvement.
Scientists stressed good diet was essential in a child’s early as the brain grows at its fastest rate during the first three years of life.
This indicated head growth at this time is linked to intellectual ability and “it is possible that good nutrition(营养)during this period may encourage excellent brain growth”
Scientists tracked the long term health and happiness of around 14,000 children born in 1991 and 1992 as part of the West Country’s Avon Longitudinal(纵向的)Study of Parents and Children(ALSPAC).
Parents were questioned about the types and frequency of the food and drink their children consumed when they were three, four, seven and eight and a half years old. According to their different changing form, these children were marked and given grades which ranged from minus two for the most healthy to 10 for the most unhealthy.
In the research, IQ was measured of 4,000 children when they were eight and half years old, using a validated(经过认证的)test-the Wechsler Intelligence Scale(韦氏儿童智力量表)for Children.
The results found after taking account of some influential factors, a leading processed food diet at the age of three was associated with a lower IQ at the age of eight and a half, whether the diet was improved after that age.
Every 1 point increase in dietary pattern score was associated with a 1.67 fall in IQ. Scientists stressed good diet was essential in a child’s early life because .
| A．the brain grows at its fastest rate during the first three years of life. |
| B．those children with a “healthier” diet must get an IQ improvement. |

If you could be anybody in the world, who would it be? Your neighbour or a super star? A few people have experienced what it might be like to step into the skin of another person, thanks to an unusual virtual reality（虚拟现实）device. Rikke Wahl, an actress, model and artist, was one of the participants in a body swapping experiment at the Be Another lab, a project developed by a group of artists based in Barcelona. She swapped with her partner, an actor, using a machine called The Machine to Be Another and temporarily became a man. "As I looked down, I saw my whole body as a man, dressed in my partner's pants," she said. "That's the picture I remember best."
The set-up is relatively simple. Both users wear a virtual reality headset with a camera on the top. The video from each camera is sent to the other person, so what you see is the exact view of your partner. If she moves her arm, you see it. If you move your arm, she sees it.
To get used to seeing another person's body without actually having control of it, participants start by raising their arms and legs very slowly, so that the other can follow along. Eventually, this kind of slow synchronised（同步的）movement becomes comfortable, and participants really start to feel as though they are living in another person's body.
Using such technology promises to alter people's behaviour afterwards-potentially for the better. Studies have shown that virtual reality can be effective in fighting racism-the bias（偏见）that humans have against those who don't look or sound like them. Researchers at the University of Barcelona gave people a questionnaire called the Implicit Association Test, which measures the strength of people's associations between, for instance, black people and adjectives such as good, bad, athletic or awkward. Then they asked them to control the body of a dark skinned digital character using virtual reality glasses, before taking the test again. This time, the participants' bias scores were lower. The idea is that once you've "put yourself in another's shoes" you're less likely to think ill of them, because your brain has internalised the feeling of being that person.
The creators of The Machine to Be Another hope to achieve a similar result. "At the end of body swapping, people feel like holding each other in their arms," says Arthur Pointeau, a programmer with the project. "It's a really nice way to have this kind of experience. I would really, really recommend it to everyone."The word "swapping" (paragraph 1) is closest in meaning to______.
| A．building | B．exchanging | C．controlling | D．transplanting |
We can infer from the experiment at the Be Another lab that______.
| A．our feelings are related to our bodily experience |
| B．we can learn to take control of other people's bodies |
| C．participants will live more passionately after the experiment |
| D．The Machine to Be Another can help people change their sexes |
In the Implicit Association Test, before the participants used virtual reality glasses to control a dark skinned digital character, ______.
| A．they fought strongly against racism |
| B．they scored lower on the test for racism |
| C．they changed their behaviour dramatically |
| D．they were more biased against those unlike them |
It can be concluded from the passage that______.
| A．technology helps people realize their dreams |
| B．our biases could be eliminated through experiments |
| C．virtual reality helps promote understanding among people |
| D．our points of view about others need changing constantly |
Let's say you want to hit the gym more regularly this year. How do you make that happen? Consider putting the habit loop to use.
Here's how it works:
A habit is a 3-step process. First, there's a cue, something that tells your brain to operate automatically. Then there's a routine. And finally, a reward, which helps your brain learn to desire the behavior. It's what you can use to create-or break-habits of your own.
Here's how to apply it:
Choose a cue, like leaving your running shoes by the door, then pick. a reward-say, a piece of chocolate when you get home from the gym. That way, the cue and the reward become interconnected. Finally, when you see the shoes, your brain will start longing for the reward, which will make it easier to work out day after day. The best part? In a couple of weeks, you won't need the chocolate at all. Your brain will come to see the workout itself as the reward. Which is the whole point, right?

Most people agree that honesty is a good thing. But does Mother Nature agree? Animals can't talk, but can they lie in other ways? Can they lie with their bodies and behavior? Animal experts may not call it lying, but they do agree that many animals, from birds to chimpanzees, behave dishonestly to fool other animals. Why? Dishonesty often helps them survive. 
Many kinds of birds are very successful at fooling other animals. For example, a bird called the plover sometimes pretends to be hurt in order to protect its young. When a predator（猎食动物）gets close to its nest, the plover leads the predator away from the nest. How? It pretends to have a broken wing. The predator follows the "hurt" adult, leaving the baby birds safe in the nest.
Another kind of bird, the scrub jay, buries its food so it always has something to eat. Scrub jays are also thieves. They watch where others bury their food and steal it. But clever scrub jays seem to know when a thief is watching them. So they go back later, unbury the food, and bury it again somewhere else.
Birds called cuckoos have found a way to have babies without doing much work. How? They don't make nests. Instead, they get into other birds' nests secretly. Then they lay their eggs and fly away. When the baby birds come out, their adoptive parents feed them.
Chimpanzees, or chimps, can also be sneaky. After a fight, the losing chimp will give its hand to the other. When the winning chimp puts out its hand, too, the chimps are friendly again. But an animal expert once saw a losing chimp take the winner's hand and start fighting again.
Chimps are sneaky in other ways, too. When chimps find food that they love, such as bananas, it is natural for them to cry out. Then other chimps come running. But some clever chimps learn to cry very softly when they find food. That way, other chimps don't hear them, and they don't need to share their food.
As children, many of us learn the saying "You can't fool Mother Nature." But maybe you can't trust her, either.A plover protects its young from a predator by______.
| A．getting closer to its young |
| B．driving away the adult predator |

| A．Some chimps lower their cry to keep food away from others. |
| B．The losing chimp won the fight by taking the winner's hand. |
| C．Cuckoos fool their adoptive parents by making no nests. |

The kids in this village wear dirty, ragged clothes. They sleep beside cows and sheep in huts made of sticks and mud. They have no school. Yet they all can chant the English alphabet, and some can make words.
The key to their success: 20 tablet computers(平板电脑) dropped off in their Ethiopian village in February by a U.S. group called One Laptop Per Child.
The goal is to find out whether kids using today's new technology can teach themselves to read in places where no schools or teachers exist. The Massachusetts Institute of Technology researchers analyzing the project data say they're already amazed. "What I think has already happened is that the kids have already learned more than they would have in one year of kindergarten," said Matt Keller, who runs the Ethiopia program.
The fastest learner-and the first to turn on one of the tablets-is 8-year-old Kelbesa Negusse. The device's camera was disabled to save memory, yet within weeks Kelbesa had figured out its workings and made the camera work. He called himself a lion, a marker of accomplishment in Ethiopia.
With his tablet, Kelbasa rearranged the letters HSROE into one of the many English animal names he knows. Then he spelled words on his own. "Seven months ago he didn't know any English. That's unbelievable," said Keller.
The project aims to get kids to a stage called "deep reading," where they can read to learn. It won't be in Amharic, Ethiopia's first language, but in English, which is widely seen as the ticket to higher paying jobs.

How fit are your teeth? Are you lazy about brushing them? Never fear: An inventor is on the case. An electric toothbrush senses how long and how well you brush, and it lets you track your performance on your phone.
The Kolibree toothbrush was exhibited at the International Consumer Electronics Show in Las Vegas this week. It senses how it is moved and can send the information to an Android phone or iPhone via a Bluetooth wireless connection.
The toothbrush will be able to teach you to brush right (don’t forget the insides of the teeth!) and make sure you’re brushing long enough. “It’s kind of like having a dentist actually watch your brushing on a day-to-day basis,” says Thomas Serval, the French inventor.
The toothbrush will also be able to talk to other applications on your phone, so developers could, for instance, create a game controlled by your toothbrush. You could score points for beating monsters among your teeth. “We try to make it smart but also fun,” Several says.
Serval says he was inspired by his experience as a father. He would come home from work and ask his kids if they had brushed their teeth. They said “yes,” but Serval would find their toothbrush heads dry. He decided he needed a brush that really told him how well his children brushed.
The company says the Kolibree will go on sale this summer, for $99 to $199, developing on features. The U.S. is the first target market.
Serval says that one day, it’ll be possible to replace the brush on the handle with a brushing unit that also has a camera. The camera can even examine holes in your teeth while you brush. Which is one of the feature of the Kolibree toothbrush?
| A．It can sense how users brush their teeth. |
| B．It can track users’ school performance. |
| C．It can detect users’ fear of seeing a dentist. |
| D．It can help users find their phones. |
What can we learn from Serval’s words in Paragraph 3?
| A．You will find it enjoyable to see a dentist. |
| B．You should see your dentist on a day-to –day basis. |
| C．You can brush with the Kolibree as if guided by a dentist. |
| D．You’d like a dentist to watch you brush your teeth every day. |
Which of the following might make the Kolibree toothbrush fun?
| A．It can be used to update mobile phones. |
| B．It can be used to play mobile phone games |
| C．It can send messages to other users |
| D．It can talk to its developers. |
What is Paragraph 5 mainly about?
| A．How Serval found out his kids lied to him. |
| B．Why Serval thought brushing teeth was necessary. |
| C．How Serval taught his kids to brush their teeth. |
| D．What inspired Serval to invent the toothbrush |
What can we infer about Serval’s children?
| A．They were unwilling to brush their teeth |
| B．They often failed to clean their toothbrushes. |
| C．They preferred to use a toothbrush with a dry head. |
| D．They liked brushing their teeth after Serval came home. |
What can we learn about the future development of the Kolibree?
| A．The brush handle will be removed. |
| B．A mobile phone will be built into it. |
| C．It will be used to fill holes in teeth |
| D．It will be able to check users’ teeth |
