4 . Is It Worth Buying Organic Food?
Organic food, grown without artificial chemicals, is increasingly popular nowadays. Consumers have been willing to pay up to twice as much for goods with organic labels (标签). However, if you think paying a little more for organic food gets you a more nutritious (有营养的) and safer product, you might want to save your money. A study led by researchers at Stanford University says that organic products aren’t necessarily more nutritious, and they’re no less likely to suffer from disease-causing bacteria, either.
The latest results, published in the Annuals of Internal Medicine, suggest that buyers may be wasting their money. “We did not find strong evidence that organic food is more nutritious or healthier,” says Dr. Crystal Smith-Spangler from Stanford. “So consumers shouldn’t assume that one type of food has a lower risk or is safer.”
For their new study, Smith-Spangler and her colleagues conducted a review of two categories of research, including 17 studies that compared health outcomes between consumers of organic against traditional food products, and 223 studies that analyzed the nutritional content of the foods, including key vitamins, minerals and fats.
While the researchers found little difference in nutritional content, they did find that organic fruit and vegetables were 20% less likely to have chemicals remaining on the surfaces. Neither organic nor traditional foods showed levels of chemicals high enough to go beyond food safety standards. And both organic and traditional meats, such as chicken and pork, were equally likely to be harmed by bacteria at very low rates. The researchers did find that organic milk and chicken contained higher levels of omega-3 fatty acids, a healthy fat also found in fish that can reduce the risk of heart disease. However, these nutritional differences were too small, and the researchers were unwilling to make much of them until further studies confirm the trends.
Organic food is produced with fewer chemicals and more natural-growing practices, but that doesn’t always translate into a more nutritious or healthier product. The U.S. Department of Agriculture (USDA) states that “Whether you buy organic or not, finding the freshest foods available may have the biggest effect on taste.” Fresh food is at least as good as anything marketed as organic.

5 . When you step into a new environment, you must have a strong wish to fit in. Fitting in means making more friends, having more influence on others and getting more chances to live a happier life.
Be confident. Confidence attracts most people. Everyone is special and there is only one person like you in this world. Spend some time thinking about your strong points.
Be kind to everyone. Kindness is the bridge to your own happiness. When people notice your kindness, they will return it one day. Always give more than you receive, and think more of others than of yourself.
Do smile to everyone every day. It makes both you and others feel happy.
If you follow what is mentioned above, you will be accepted by people around you. As a result, you will fit in very well and enjoy your new life.
A.Be active in group activities. |
B.A pleasant smile costs the least and does the most. |
C.Here is some advice that can help you. |
D.If so, you will be able to build up confidence step by step. |
E.A person who cares for others is popular everywhere. |
F.However, everybody needs friends. |
G.Even so, it often leaves one to wonder if we fit in well. |
6 . Art and science may seem like opposite things. One means the creative flow of ideas, and the other means cold, hard data-some people believe. In fact, the two have much in common. Now, a study finds art can help students remember better what they have learned in the science class.
Mariale Hardiman, an education specialist at Johns Hopkins University, noticed that students who used art in the classroom listened more carefully. They might ask more questions. They might volunteer more ideas. What’s more, students seemed to remember more of what they had been taught when their science lessons had involved(涉及) art. To prove that, Hardiman teamed up with some researchers and six local schools.
In the experiment, the researchers worked with teachers in 16 fifth-grade classrooms. They provided traditional science lessons and art-focused ones. In a traditional science class, for example, students might read aloud from a book. In the art-focused one, they might sing the information instead.
The team randomly assigned(随机分配) each of the 350 students to either a traditional science classroom or an art-focused one. Students then learned science using that way for the whole unit-about three weeks. When they changed to a new topic, they also changed to the other type of class. This way, each student had both an art-focused class and a traditional one. Every unit was taught in both ways, to different groups of students. This enabled the researchers to see how students did in both types of classes.
The team found that students who started off in a traditional class performed better after they moved into an art-focused class. But those who started off in an art-focused class did well even when they went back to a traditional science class. These students appeared to use some of the art techniques(技巧) after going back to a traditional class. Classroom teachers reported that many students continued to sing the songs that they learned after finishing the unit. “The more we hear something, the more we retain it,” Hardiman says. “It suggests that the arts may help students apply creative ways of learning on their own.”

9 . What a day! I started my new school this morning and had the best time. I made lots of new friends and really liked my teachers. I was nervous the night before, but I had no reason to be. Everyone was so friendly and polite. They made me feel at ease. It was like I’d been at the school for a hundred years!
The day started very early at 7:00 am. I had my breakfast downstairs with my mom. She could tell that I was very nervous. Mom kept asking me what was wrong. She told me I had nothing to worry about and that everyone was going to love me. If they didn’t love me, mom said to have a good talk with them. I couldn’t stop laughing.
My mom dropped me off at the school gate about five minutes before the bell rang. A little blonde girl got dropped off at the same time and started waving (招手) at me. She ran over and told me her name was Abigail. She was very nice and we became close straight away. We spent all morning together and began to talk to another girl called Stacey. The three of us sat together in class all day and we even made our way home together! It went so quickly. Our teacher told us that tomorrow we would really start learning and developing new skills.
I cannot wait until tomorrow and feel as though I am really going to enjoy my time at my new school. I only hope that my new friends feel the same way, too.
