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. However, if you think paying a little more for organic food gets you a more nutritious and safer product, then you'd better 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.
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.
1.What does the underlined sentence in the first paragraph mean? ______

B.traditional food was grown with more natural methods
C.both organic and traditional food they examined were safe
D.there was not a presence of any forms of bacteria in organic food

The sharing economy has grown in recent years to include everything from apartment sharing to car sharing to community tool sharing. Since 2009, a new form of sharing economy has been emerging in neighborhoods throughout the US and around the world-Little Free Libraries. The libraries are boxes placed in neighborhoods where residents can take out and leave books. Little Free Libraries come in all shapes and sizes. Some libraries also have themes, focusing on books for children, adults, or tour guides.
In 2009, Tod Bol built the first Little Free Library as a gift to his mother, a devoted reader. When he saw the people of his community gathering around it, exchanging conversations as well as books, he knew he wanted to take his simple idea further. "I think Little Free Libraries open the door to conversations we want to have with each other." Bol said.
Since then, his idea has become a movement, spreading from state to state and country to country. According to Little Free Library. org, there are now 18,000 of the little structures around the world, located in each of the 50 US states and 70 countries in Europe, Africa and Asia.
The Internet has helped to spread Little Free Libraries. But an Atlantic article says the little structures serve as a cure for a world of e-reader downloads. The little wooden boxes are refreshingly physical and human. For many people, the sense of discovery is Little Free Libraries' main appeal: "A girl walking home from school might pick up a graphic novel that gets her excited about reading; a man on his way to the bus stop might find a volume of poetry that changes his: outlook on life," says the Atlantic article. "Every book is a potential source of inspiration."

Sarah got a sudden sinking feeling, and she could sense approaching danger. Without thinking she stood up, and faced toward the direction of the sound. That's when she saw a gray tail through the bushes. Desperately Sarah climbed up a tall pine tree. She knew its smell would be of some help. The merciless creature stepped in, sniffing around.
The branch cracking slightly, the wolf looked around, then up and made direct eye contact with Sarah. It gave a short howl, and then two more large wolves came running. Sarah grabbed a branch and threw it far behind them, who dashed after it, but weren't gone for long. They had realized they were tricked. They started jumping at her legs, and the worst happened. The branch, her lifeline, gave out on her and she landed onto the ground, nearly on top of the lead wolf. They immediately surrounded her, glaring at her in the eyes. She raised her head, thinking to herself, "If this is the way I am going to die, I might as well die with dignity." Grabbing the branch that betrayed her, she stood up, smacking it around, and the wolves began backing up.
Finally she was able to get out of the circle, and ran over to a spot with a bunch of empty bottles. She tied one to each fist, and then smashed them on a rock so that if she hit one of the wolves, the broken glass would cause a lot more damage. Meanwhile, Sarah grabbed a branch and was able to reach out and smack the lead wolf in the face. He fell down and the other wolves began sniffing at him, then she rushed as fast as possible. "I will never be able to outrun them, but I have to try", she thought to herself. She ran as if she never ran before. Finally the wolves were out of sight.

C.Its smell could prevent her being discovered D.She was playing hide-and-seek with a creature
2.The moment Sarah threw a branch behind the wolves, .

3.What can we learn from the underlined sentence in paragraph 2?
A.Sarah was too frightened to behave crazily. B.Sarah thought she was sure to die.
C.Sarah was thinking how to end her life. D.Sarah was determined to fight for survival.
4.Which of the following can best describe Sarah's escape from the wolves?

I know things can get difficulty in life. Everyone has the different story. In the past few years that have gone, I have changed from not wanting to continue with my studies to laugh every night and living life to the fullest. Moreover, I’ve learned that it’s all right to feel lower and cry sometimes. That is okay to have no one by your sides. If you get been knocked down 7 times, get up the 8th time. Listening to music; find and do something that you enjoy. In tough times, you are your biggest help. I promise that things would get better.
