You know eating fruit and vegetables does good. But do you know it can also make you look good? People who increased their intake over just six weeks developed a healthy glow and appeared more attractive, researchers found. Scientists at St Andrews University found eating them slightly increased yellow and red pigments in the volunteers' skin. They monitored the food intake of 35 people and took pictures of their faces, arms and hands using a sensitive camera at the start, and after three and six weeks. Increasing their intake of greens by 2.9 portions a day was found to make the person look more healthy and an extra 3.3 portions could enhance their attractiveness, when their photographs were rated by others.

Fruit and vegetables are rich in carotenoids(類胡蘿卜素)，which are known to protect against cell damage from pollution and UV rays, and can also prevent age-related diseases including heart disease and cancer. But while it was known eating extreme amounts of certain vegetables such as carrots could turn skin orange，it was not known a small increase was perceptible(被覺察）to others—and was seen as appealing.

A camera measured changes to the skin's redness, yellowness and lightness, and found it significantly changed in people who naturally increased their intake. These changes were not evident in three weeks. Using light sensors, the researchers showed these red and yellow hues were linked with the levels of carotenoids in their skin. There are hundreds of carotenoids but those thought to have the most dramatic effect are lycopene(番茄紅素)—which gives tomatoes and red peppers their red colour—and beta-carotene found in carrots as well as broccoli, squash, and spinach. Skin colour is also affected by chemicals called polyphenols(多元酚)，found in apples, blueberries and cherries, which cause blood rush to the skin surface.

1.What do we know from the research?

A. If you take in a little more fruit and vegetables, you will obviously look more attractive in three weeks.

B. People who increased their intake of greens by 3.3 portions a day were found the most attractive after six weeks.

C. Increasing your intake of greens by 2.9 portions a day can greatly improve your health.

D. The researchers took the pictures of the 35 people in the research at different stages.

2.Which of the following is NOT the function of carotenoids？

A. They can protect against cell damage from pollution and UV rays.

B. They can prevent heart disease and cancer.

C. They can keep you in good health.

D. They can prevent age-related diseases.

34. 3.Which of the statements is NOT TRUE according to the passage?

A. We've already known eating extreme amounts of carrots can turn skin orange.

B. We knew in the past that eating a few more carrots could make us look appealing.

C. The research showed the improvement in skin is linked with the levels of carotenoids in it.

D. Among hundreds of carotenoids, lycopene is thought to have the most dramatic effect

4.Which can be the best title of the passage?

A. Eating fruit and vegetables does good.

B. Eating fruit and vegetables makes you look good.

C. How to become attractive？

D. Fruit and vegetables are rich in carotenoids.

We are all called upon to make a speech at some point in life, but most of us don’t do a very good job. 1.

So, you have to give a speech and you are terrified. You get nervous, you forget what you want to say, you stumble over words, you talk too long, and you bore your audience. Later you think, “Thank Goodness, it’s over. I’m just not good at public speaking. I hope I never have to do that again.”

You may have never heard of Lanthanum, Cerium or Neodymium, but these elements (元素) and others known as “rare earth” play a major role in modern technology. They can actually be found in many places on the earth, but not in quantities that can be mined. Only a few countries — China, America, India, Australia, Brazil and Malaysia have any that can be mined enough to be traded.

Even though some of these elements such as Cerium are as abundant as Copper, they are not found in concentrated amounts on the earth’s surface. They are often mixed together with other metals, which makes extraction (提取) of these elements an expensive and an environmentally messy process. It was due to this reason that the term “rare earth” was invented.

Rare earth metals are used widely in our life. Rechargeable car batteries, computers, iPhones, DVD players, computer monitors, televisions, lighting, lasers, glass polishing, and superconductors all use quantities of rare earth metals. Also, with the advancement in “green” technology like solar panels, these shiny materials are becoming more important than ever. An average electric car uses 10 pounds of Lanthanum for its rechargeable battery!

America has large deposits (存儲量) of rare earths and has one of the first mines. It was opened in Southern California in 1940. The element “Europium” was the first metal to be separated in quantity for use in color televisions. However, in the 1980’s and 1990’s, as China started producing these elements in Inner Mongolia, the mines in America and elsewhere could not keep pace. The mine in Mountain Pass, California also failed environmental regulations and shut down in 2002.

Now, recognizing the importance of having more than one supplier of this important resource, other rare earth owning countries like India and Australia are either dusting off their rare earth mines or speeding up their production. It is believed that the debate over rare earths will become louder in the coming months and years.

1.What can we learn about rare earths?

A. They are actually as abundant as Copper.

B. They can be mined easily as other metals.

C. They can only be found in a few countries.

D. They are not really as rare as they are named.

2.Compared with China, America _____.

A. paid more attention to Europium

B. has larger deposits of rare earths

C. started producing rare earths earlier

D. has more rare earth mines

3.It can be inferred from the text that rare earths _____.

A. are now in great demand

B. can now be used in few fields

C. are harmful to the environment

D. will soon be replaced by other metals

Take That Tiger Mom

In the ongoing battle between Tiger Moms, French Mamas, and everyone else who wants to know what is the best way to raise their kids, a new study adds evidence that the extreme Tiger-style may do more harm than good.

Authoritarian parents are more likely to end up with disrespectful children with violent behaviors, the study found, compared to parents who listen to their kids with the goal of gaining trust.

It was the first study to look at how parenting styles affect the way teens view their parents and, in turn, how they behave.

The study considered three general styles of parenting. Authoritative parents are demanding and controlling while also being warm and sensitive to their children’s needs.

Authoritarian parents, on the contrary, are demanding and controlling without the appearance of caring, attachment and receptiveness. They take a “my way or the highway” approach to their kids.

Permissive parents, the third group, have warm and receptive qualities, but they set few boundaries and carry out few rules.

Using data on early 600 kids from an ongoing study of middle school and high school students in New Hampshire, researchers from the University of New Hampshire were able to find “my way or the highway” parenting with more violent behaviors like robbery, drug-taking, and attacking someone else with the intention of hurting or killing.

Firm but loving parenting, on the other hand, led to fewer lawbreakers. Permissive parenting, surprisingly, didn’t seem to make much of a difference either.

To explain the link between parenting style and behavior in kids, the researchers suggested that what matters most is how reasonable kids think their parents’ power is. This sense comes when kids trust that their parents are making the best decisions for them and believe that they need to do what their parents say even if they don’t always like how their parents are treating them.

When kids respect the power of their parents, the researchers reported in the journal of Adolescence, their behavior is better. Previous research has also linked firm but caring parenting with kids who have more self-control and independence.

“When children consider their parents to be the reliable figure, they trust the parents and feel that they have a duty to do what their parents tell them to do,” said lead researcher Pick Trinkner. “This is very important as the parent doesn’t have to rely on a system of rewards and punishments to control behavior and the child is more likely to follow the rules when the parent is not physically present.”

1.Tiger Moms and French Mamas are mentioned in the passage to _______.

A. give an example of authoritarian parenting

B. show the advantage of parenting

C. compare two types of parenting

D. introduce the topic

2.According to the research, what kind of parenting style is likely to cause children’s criminal behaviors?

A. Caring parenting. B. Permissive parenting.

C. Authoritarian parenting. D. Authoritative parenting.

3.Which of the following probably belongs to the action of the permissive parents?

A. Allowing the kids to stay up late at weekends as the kids like.

B. Beating the kids if the kids don’t follow their instructions.

C. Listening to the kids’ request and giving their demands.

D. Setting some rules and checking the kids’ behaviors.

4.According to the passage, children are more likely to obey the rules when _______.

A. their parents listen to them totally

B. they believe in and accept their parents

C. their parents are sensitive to their needs

D. their parents demand and control their behaviors

Failing in something isn’t a really nice feeling, but Scotland’s Fettes College in Edinburgh wants to show its students that failure isn’t something to fear and is actually something to accept willingly!

The boarding school held “failure week” to celebrate taking risks and learning from them. Whether in sports or school, children often face lots of pressure to succeed and do well, and the school was becoming concerned.

“Young people from all walks of life live in a high-pressure environment where they are trying very hard to achieve a level of perfection,” said Sue Bruce, head of personal and social education in the school.

“This week at Fettes we have been focusing on one of the most misunderstood parts of success: failure. While we are often scared of failure, it is important to learn that it is only through failing, often many times, that we learn how to succeed. All through the week, we have looked at the experiences of some of the most successful inventors, artists and businessmen, who failed hundreds, if not thousands of times on their journey to success,” read a letter on Fettes College’s website.

To celebrate failure, students were encouraged to try something they’ve never done before, like playing an instrument or dancing in front of audiences. A number of students stepped up and tried things that they finally failed in, but they had fun and enjoyed the experience. “The concert was extremely enjoyable, proving that we should always try not to worry about failure and have a go!” read another note on the website. Students were also taught about famous people like J.K. Rowling and Richard Branson who failed many times before they finished what they set out to do.

“If they let the fear of failure stop them from doing something, they are actually stopping themselves from learning, developing, and potentially succeeding,” said Bruce.

1.What is the purpose of the boarding school to hold “failure week”?

A. To get the students involved in social activities.

B. To help the students accept and learn from failure.

C. To make the students study even harder.

D. To teach the students how to get relaxed.

2.During the “failure week” the students could do the following things EXCEPT ___________.

A. taking risks

B. learning from others’experiences

C. trying something new

D. trying to entertain themselves

3.What can we learn from the passage?

A. Many successful people are lucky and achieve success easily.

B. Because we are often scared of failure ,we never succeed.

C. The fear of failure can stop the students from learning and succeeding.

D. The students who failed in trying new things felt depressed.

“Men get all the breaks!” the veteran (老練的) teacher announced to me. A cold greeting. Her stare stabbed like an icicle (冰柱).

“Hello,” I countered, extending my hand. “I guess we’ll be teaching together this year.”

“I swear, all you have to do is wear pants and walk into an elementary school and they hire you! It makes me sick!” I would have responded, but she turned her back to me and stomped off down the hall.

Who would have imagined that the biggest challenge I would face during my first year on the job would not be students, but fellow teachers?

“You can’t put that there!” Another teacher burst into my classroom. “You can’t put the teacher’s desk at the back of the room!”

“Pardon?”

“If you put your desk way back there, you won’t be able to see them cheating!”

Next I was told I must not arrange student desks into abutting clusters because “the students might talk too much.”

At home my wife kept assuring me, “You’re there for the kids. When you meet your students, things will be different.” And she was right. One day the bell rang and there were thirty-five wonderful sixth graders sitting at their desks (still arranged in clusters) and it was different. I was happy.

“Welcome to sixth grade.” I began the year as I’d rehearsed for months. “You’ll notice,” I continued, “my desk is at the back of the room.” They chuckled. “I don’t want that desk between us. I want to be involved in your learning and involved in your lives.”

In the days that followed, I ate with my students at lunch (“Wilcox shouldn’t do that!”); I played with my students at recess (“That’s unheard of!”); I read with my students in the library (“He’s wasting time!”); I even stayed after school with some boys who got in trouble with the principal (“He’s undermining the school’s entire discipline program!”).

I went home to my wife. “Don’t worry,” she said. “They’re just threatened by you because you’re new and you’re good. Let the other teachers know you’re not a threat. Just keep being nice to them.”

Obediently, I pulled out the Golden Rule, dusted it off, and vowed to start again. As I did with the children, I started looking for specific, positive things I could build upon and reinforce sincerely in my colleagues: “Nice job on the announcements this morning!” “Wow! I like that worksheet you made up.” “Man, your kids walked down the hall so quietly.” “I heard your class singing great songs. You do a super job with music!”

“I like your bulletin board,” I said to Mrs. Icicle Eyes.

“Really?” she asked. “It’s just the same old thing I put up every year.” She reached out and straightened a sagging border. Then, not unlike one of my students, she added, “Do you really like it?”

“Yes,” I answered firmly. As sure as sun beams, the Golden Rule was shining, and things were finally warming up.

That very afternoon, a few parents went to the principal’s office asking if their sixth graders could be moved into my class. Of course the students were not transferred, but when the grapevine circulated the request, up went the old barbed wire fence. Complete with machine guns.

I continued to do the best job I could. I worked. I taught. I cared. I waited for a breakthrough moment.

Months passed. It was lunch recess. I asked a boy walking down the hall. “Have you seen Mrs. So-and-So?” I was, in fact, searching for Mrs. Icicle Eyes. I needed to consult with her.

Grinning, he came toward me as if sharing a secret. “She’s outside shooting baskets with the girls!”

“She’s playing basketball with the girls?” I asked incredulously.

“Yeah,” he nodded. I smiled. I didn’t say another word. But my smile inside was even bigger than the one on my face.
