Many people with autism also have difficulty understanding facial expressions and the feelings of others. They also have trouble making friends of the same age. Doctors have learned how to recognize autism, but much is still unknown about its causes. Researchers at Harvard University have come closer to finding answers. They found that women exposed to the highest levels of fine particulate air pollution late in their pregnancies are two times more likely to give birth to a child with autism. The findings appeared in Environmental Health Perspectives -- a publication of the National Institute of Environmental Health Sciences. The study found that the women who were around high levels of fine particulate matter air pollution were at highest risk of having an autistic child. The increased risk of these women was two times that of women who lived in areas with low levels of fine particulate pollution. The researchers found that the timing of exposure to pollution was important. They found no increased risk of autism in children whose mothers were around high levels of pollution before becoming pregnant. And the study found air pollution does not seem to increase the risk of children developing autism after they are...

Q: Read the following article and select the best answer. Article: Travel Unaccompanied Now many young people are traveling around the world on their own, not because they have no one to travel with, but because they prefer to go alone. Kristina Wegscheider from California first traveled alone when she was at college and believes that it is something everyone should do at least once in their life. "It opens up your mind to new things and pushes you out of your comfort zone." Wegscheider has visited 46 countries covering all seven continents. In foreign countries, with no one to help you read a map, look after you if you get ill, or lend you money if your wallet is stolen. It is challenging. This is what drives young people to travel alone.It is seen as character building and a chance to prove that they can make it on their own. Chris Richardson decided to leave his sales job in Australia to go traveling last year.He set up a website, The Aussie Nomad, to document his adventures. He said he wished he had traveled alone earlier. "The people you meet, the places you visit, or the things you do, everything is up to you and it forces you to grow as a person," said the 30-year-old. Richardson describes traveling alone like "a shot in the arm", which "makes you a more confident person that was ready to deal with anything". He said: "The feeling of having conquered something on my own is a major part of what drives me each day when I'm dealing with a difficult task. I walk around with my head up because I know deep down inside that nothing is impossible if you try." The great 19th century explorer John Muir once said: "Only by going alone in silence can one truly get into the heart of the wilderness." Question: Which of the following will Kristina Wegscheider agree with? - Traveling alone is a necessary experience for everyone. - It is more meaningful to travel in foreign countries. - It is comfortable to travel around without a friend. - Traveling abroad helps people to find new things.
A: Traveling alone is a necessary experience for everyone.

*Question*
Read the following article and select the best answer. Article: Luo Jingyu, 19, has four years of experience of running business. He is also a freshman in the arts department of Hubei University. Luo Jingyu is from an ordinary family. He said, "My parents told me if I wanted something I should make an effort to get it, so I earned pocket money by doing housework when I was little." The dream of running his own business grew in his heart. He said, "I want to be a successful person, like Alibaba's Ma Yun." When Luo was a junior student, he had the idea of selling lanterns when he saw many people flying Chinese lanterns in a square. Luo bought some lanterns from a store, but the sales were not as good as he had expected. Then he found another way to do business. He bought lanterns on the Internet at a very low price. Finally he easily made 5,000 yuan in two days. With a happy beginning, Luo planned to open a dress shop. "My parents didn't support me opening a dress shop, so I had to borrow 120,000 yuan for it." Although he did market research before starting, the business wasn't very good because his taste in fashion wasn't accepted by customers. The shop eventually closed down after half a year. After experiencing a big loss, he decided to do something he was familiar with --- selling painting tools. As a fine arts student, he knew the market. He convinced his friends to invest one million yuan in his shop. With a good business mind and a lot of effort, the sales of the shop reached six million yuan in a year.
