_1.__： less red meat and more fiber, less saturated fat (饱和脂肪) and more fruit and vegetables, right? Wrong, according to a controversial new book by nutritionist Zoe Harcombe. In the book, Harcombe charts her careful journey of research into studies that underpin (巩固) dietary advice—and her myth(误区)－breaking conclusions are surprising.
Myth：__2.__.
“Real fat is not bad for us，”says Harcombe.“It’s manmade fats we should be demonizing.”Why do we have this idea that meat is full of saturated fat? In a 100g pork chop, there is 2.3g of unsaturated fat and 1.5g of saturated fat.
Myth: We should eat more fiber.
For three decades, we have eaten fiber into our bodies to help us feel full and keep our digestive systems moving.“__3._”， says Harcombe.
The advice to eat more fiber is put forward along with the theory that we need to clean our digestive systems. But essential minerals are absorbed from food while it is in the intestines (肠道), so why do we want to wash everything out? Concentrate on not putting bad foods in.
Myth: You need to eat five portions of fruit and vegetables a day.
“Fiveaday is the most well-known piece of nutritional advice，” says Harcombe.“You’d think it was based on firm evidence of health benefit.__ 4.__.‘Fiveaday’started as a marketing campaign by 25 fruit and vegetable companies and the American National Cancer Institute in 1991.There was no evidence for any cancer benefit.”
Myth: Fruit and vegetables are the most nutritious things to eat.
Apparently not Harcombe allows that vegetables are a great addition to the diet—if served in butter to deliver the fat－soluble(dissolved) vitamins they contain—but natural sugar, the fruit sugar in fruit, goes straight to the liver and is stored as fat.“__5.__”， says Harcombe, who adds “Vitamins and minerals in animal foods—meat, fish, eggs and dairy products—beat those in fruit hands down.”
A．Think again
B．This is not a good idea
C．Fat is bad for us
D．Fruit is best avoided by those trying to lose weight
E．Want to lose weight? Don’t trust these
F．We need take more exercise
G．We think we know what to eat
Everyone has got two personalities — the one that is shown to the world and the other that is secret and real．You don’t show your secret personality when you're awake because you can control your behavior，but when you're asleep, your sleeping position shows the real you. In a normal night, of course，people frequently change their position. The important position is the one that you go to sleep in．
If you go to sleep on your back, you’re a very open person. You normally trust people and you are easily influenced by fashion or new ideas．You don’t like to upset people，so you never express your real feelings．You’re quite shy and you aren't very confident．
If you sleep on your stomach，you are a rather secretive person. You worry a lot and you're always easily upset. You’re very stubborn, but you aren't very ambitious. You usually live for today not for tomorrow. This means that you enjoy having a good time．
If you sleep curled up, you are probably a very nervous person. You have a low opinion of yourself and so you’re often defensive. You're shy and you don't normally like meeting people. You prefer to be on your own．You're easily hurt．
If you sleep on your side, you have usually got a well-balanced personality. You know your strong points and weaknesses. You’re usually careful. You have a confident personality. You sometimes feel anxious，but you don't often get depressed. You always say what you think even if it annoys people．

Speaking two languages can actually help offset(抵消) some effects of aging on the brain, a new study has found.
Researchers tested how long it took participants to switch from one cognitive(认知的) task to another, something that’s known to take longer for older adults, said lead researcher, Brian Gold, a neuroscientist at the University of Kentucky.
Gold’s team compared task-switching speeds for younger and older adults, knowing they would find slower speeds in the older population because of previous studies. However, they found that older adults who spoke two languages were able to switch mental activities faster than those didn’t. The study only looked at life-long bilinguals, defined in study as people who had spoken a second language daily since they were at least 10 years old.
Gold and his team asked 30 people, either bilingual or monolingual, to have a series of tests. They found that bilingual people were not only able to switch tasks faster, they had different brain activity than their monolingual peers.
Kristina called bilingualism "a beautiful natural experiment”, because people grow up speaking two languages, and studies have shown that they get certain cognitive benefits from switching between languages and determining which to respond with based on what's going on around them.
Gold said he grew up in Montreal, where he spoke French at school and English at home, prompting relatives to question whether his French language immersion（专心）would somehow hinder his ability to learn English.
"Until very recently, learning a second language in childhood was thought of as dangerous," he said. "Actually, it's beneficial.”

American government suggests that children and teens should get 60 minutes of physical activity every day. But less than half of children and just 10% of teens meet these suggestions. What’s the deal?
It’s reported that about 44million US kids participate in organized sports(such as baseball, softball, soccer).But a new study says just one-quarter of kids get the government-recommended amount of exercise when they show up for team practices. The study, published online last month in a medical journal, says younger kids and boys do better than teens and girls.
The study looked at 200 kids aged 7 to 14 who played on soccer, baseball and softball teams. The kids wore sensors to measure their activity during practices.
During each practice, kids averaged 30 minutes of downtime(停工期). “It is not clear how much physical activity is provided by youth sports practices,” say the California-based authors of the study. “Much of the time may be inactive, such as receiving verbal instructions and waiting for turns.”
What’s a parent or coach—or kid—to do? The authors of the study suggest increasing the number of practices, extending the time of practices and changing it up(加快)during practices. For example, the coach could give each player a ball at the same time. Rather than focusing on one player’s skills, it’s best to get the whole team moving.
But, the study says, the bottom line is that team sports aren’t enough exercise. For a child to meet the US physical activity suggestions, the kid will have to do more than just join a team. Exercise is also necessary during breaks, during physical education class, after school and even on the way to school.

D. kids and headmasters
4.What’s the best title of the passage?
A. Necessary for Kids to Exercise
B. Kids for Fun?
C. How to Keep Fit
D. Not Enough Exercise?

You may not pay much attention to your daily elevator ride. Many of us use a lift several times during the day without really thinking about it. But Lee Gray, PhD, of the University of North Carolina, US, has made it his business to examine this overlooked form of public transport. He is known as the “Elevator Guy”.
“The lift becomes this interesting social space where etiquette (礼仪) is sort of odd (奇怪的),” Gray told the BBC. “They are socially very interesting but often very awkward places.”
We walk in and usually turn around to face the door. If someone else comes in, we may have to move. And here, according to Gray, lift users unthinkingly go through a set pattern of movements. He told the BBC what he had observed.
He explained that when you are the only one inside a lift, you can do whatever you want – it’s your own little box.
If there are two of you, you go into different corners, standing diagonally (对角线地) across from each other to create distance.
When a third person enters, you will unconsciously form a triangle. And when there is a fourth person it becomes a square, with someone in every corner. A fifth person is probably going to have to stand in the middle.
New entrants to the lift will need to size up the situation when the doors slide open and then act decisively. Once in, for most people the rule is simple – look down, or look at your phone.
Why are we so awkward in lifts?
“You don’t have enough space,” Professor Babette Renneberg, a clinical psychologist at the Free University of Berlin, told the BBC. “Usually when we meet other people we have about an arm’s length of distance between us. And that’s not possible in most elevators.”
In such a small, enclosed space it becomes very important to act in a way that cannot be construed (理解) as threatening or odd. “The easiest way to do this is to avoid eye contact,” she said.
