I'm taking a test and have to guess the right answer to the question after the article. Article: The new high-speed railway line between Urumqi,capital of the Xinjiang Uygur self-governing region,and Lanzhou,capital of Gansu province,has cut train travel time by half to less than 12 hours. The dramatic improvement will benefit many families planning reunions for Spring Festival. "For the first time,I feel home is not that far away after all,"said Liang Shaofu as he boarded a high-speed train in Urumqi with six members of his family. The 35-year-old left Lanzhou to set up a dry fruit business in Xinjiang eight years ago,and he has now settled in Urumqi. The 1,776-km line,which passes through Qinghai province and is the country's first high-speed railway to be built in a high-altitude region,came into service on Dec 26. "We normally drive home for Spring Festival to avoid the difficulties of buying seven train tickets for the whole family during the peak season,"Liang said."Driving can be very tiring and dangerous sometimes,so one year we even decided not to go back to Lanzhou simply to avoid the trip." More than 600,000 passengers traveled on the line during its first month,and the Urumqi Railway Bureau said the introduction of high-speed services will ease transport pressure during the Spring Festival peak season. The existing usual railway line could no longer support Xinjiang's development.All passenger trains will gradually shift to the new link,leaving the old one to be used for goods.As a result,Xinjiang's annual goods ability could reach 200 million metric tons from the current 70 million. The line passes through areas that experience high winds,and it also crosses parts of the deserted Qinghai-Tibet Plateau and the bone-dry sands of the Gobi Desert. The project could help China to promote its high-speed railway technology abroad,said Ma Xi zhang,director of the Lanzhou-Xinjiang railway project's _ management department in Xinjiang. Question: From the passage we can learn _ . Options: A: Xinjiang's annual goods ability can increase nearly four times B: the new railway technology may help more railway lines to be built abroad C: the high-speed railway lines can't be built across the bone-dry sands D: the old railway lines can only carry goods now

I'm taking a test and have to guess the right answer to the question after the article. Article: I cheated on a unit test in math class this morning during second period with Mr. Burke. Afterward, I was too sick to eat lunch just thinking about it. I came straight home from school, went to my room, and lay on the floor trying to decide whether it would be better to run away from home now or after supper. Mostly I wished I was dead. Yesterday Mr. Burke announced there'd be a unit test and anyone who didn't pass would have to come to school on Saturday, most particularly me, since I didn't pass the last unit test. I did plan to study just to prove to him that I'm plenty smart--which I am mostly--except in math. Anyway, I got my desk ready to study on . Just when I was ready to work, Nicho came into my room with our new rabbit and it jumped on my desk and knocked the flashcards all over the floor. What a mess! Nicho and I finally took the rabbit outside but then Philip came to my room and also Marty from next door and before long it was dinner. After dinner my father said I could watch a special on television if I'd done all my homework. Of course I said I had. That was the beginning. I felt terrible telling my father a lie about the homework. It was nine o'clock when I got up to my room and that was too late to study for the unit test so I lay in my bed with the light off and decided what I would do the next day when I was in Mr. Burke's math class not knowing the 8- and 9-times tables. So, you see, the cheating was planned after all. The next day, I'd go into class as usual, acting like things were going just great. I'd sit down next to Stanley Plummer--he is so smart in math it makes you sick--and from time to time, I'd glance over at his paper to copy the answers. Lying on the floor of my room, I begin to think that probably I've been bad all along. It just took this math test to clinch it. I'll probably never tell the truth again. I tell my mother I'm sick when she calls me to come down for dinner. She doesn't believe me, but puts me to bed anyhow. I lie there in the early winter darkness wondering... Question: The author's father kissed the author good night because _ -. Options: A: he had done something unusual B: he promised to study math harder C: he was willing to take a make-up test D: he realized his mistake and had the courage to admit it

I'm taking a test and have to guess the right answer to the question after the article. Article: In the near future,we may be using our eyes to operate our smart-phones and tablets,even when it comes to playing popular games like Fruit Ninja. The Gaze Group has been developing eye-controlled computer technology for nearly 20 years.But those devices have been firstly designed to help those with disabilities,and are very expensive. "After a while,we figured out that probably the best way is to go for a mass-market way," says Gaze's Sune Alstrup Johansen."where everybody would have this available." Johansen and some of his colleagues have formed a new company,the Eye Tribe,which is hoping to develop the technology on a mass commercial level. The technology works with the help of the computing device toward the user's face. After making sure of the user's eye movements,the technology is then able to easily find where a person's eyes are moving,and then allow the eyes to control a cursor . "Our software can then determine the location of the eyes and know where you're looking on the screen to make sure what you're looking at,"reads an explanation on the Eye Tribe site. There has been a gradual change toward hands-free technology in recent years, particularly in the gaming world.Recently Xbox released the Kinect device,which lets users control their Xbox and play certain games using only their hands,legs and voices. But still,most of these devices have been more of a _ than a practical way to use one's hands to control a mobile device.Johansen said a replaceable filter would be a cheap,convenient way for most consumers. And even as companies like The Eye Tribe work to create such a product for the average user, making the eye-controlled technology more accessible and less expensive will have similar benefits for physically disabled users.
