Article: Skipping classes, particularly big lectures where an absence is likely to go undetected, is a tradition among college undergraduates. These days, however, some professors say they're seeing more _ , as students make the most of new technologies as learning aids. Americ Azevedo taught an "Introduction to Computers" at the University of California, Berkeley, US last semester. By visiting the course's website, the 200 enrolled students could download audio recordings or watch digital videos of the lectures, as well as read the instructor's detailed lecture notes. But there was one big problem: So many of the undergraduates relied on the technology that at times only 20 or so actually showed up for class. Doug Suda, 19, a student in Azevedo's class last semester, said he skipped about three-quarter of the lectures. It's largely because he was busy with an off-campus job and was taking the course to fulfill a business major requirement. At the end of the term, Suda prepared hurriedly for the final exam by watching videos of about 15 lectures over three days. "If I hadn't that... I would probably fail the class," said Suda, who instead received a B-plus. Despite the concerns about absenteeism, schools are increasingly experimenting with ways to let students watch or listen to lectures on their computers or digital music players, like iPods. Last month, Harvard Medical School began "Podcasting" lectures. Students can download them into digital musical players, and study while they, say, go for a walk. As many academics accept the electronic innovation, others are pushing back. To encourage attendance, they are applying low-tech tactics, like giving more surprising quizzes or cutting back their online offerings. Lee Chanian, a UCLA economics professor, says "too much technology leads to passive learning environment and encourage more absenteeism". He now puts fewer lecture materials online, and provides extensive notes only for the most complicated topics.
Question: At times only 20 or so undergraduates showed up for Americ Azevedo's class because _ .
Options: (A) so many undergraduates relied on digital learning aids (B) so many undergraduates have off-campus jobs. (C) his lectures were boring (D) the exam was easy to pass
Asnwer: D
No

Article: Some kinds of mental skills naturally decrease as people get older. Yet research seems to show that some training can improve such skills. A recently published study also appears to demonstrate that the good effects of training can last for many years after that training has ended. Researchers at Johns Hopkins University in Maryland wanted to learn how long memory and thinking skills would last in older people who trained to keep them. The people were part of the ten-year research project. They were taught methods meant to improve their memory, thinking and ability to perform everyday tasks. More than 2,800 volunteered for the study called ACTIVE - short for Advanced (Cognitive) Training for Independent and Vital Elderly. Most studied when they were more than 70 years old. The volunteers took one of several short training classes meant to help them keep their mental abilities. One class trained participants in skills including how to remember word lists. Another group trained in reasoning. A third group received help with speed-of-processing - speed of receiving and understanding information. A fourth group - the control group did not get any training. Earlier results had established that the training helped the participants for up to five years. Now, lead study writer George Rebok says, the research showed most of the training remained effective a full ten years later. Professor Rebok and his team found that the people trained in reasoning and speed-of-processing did better on tests than the control group. "We are wondering whether those effects which endured over time would still be there ten years following the training, and in fact, that's exactly what we found." The effect on memory, however, seemed not to last as long. Still, the old people in any of the three classes generally reported less difficulty in performing daily activities than the control group. The total training time for the older people was between 10 and 15 hours.
Question: Which statement is true according to the text?
Options: (A) This kind of training can only have effect on people for a few years. (B) The people were trained during a period of ten years. (C) All the people who were studied were more than 70 years old. (D) The second group were trained how to remember word lists.
Asnwer: B
Yes

Article: Must-Read about Notting Hill Carnival Route The carnival procession itself begins at 9am on both Sunday and Monday. It starts on Great Western Road, winding its way along Chepstow Road, then on to Westbourne Grove, and then down Ladbroke Grove. See our Notting Hill Carnival map for the full route. Bus While extra services will be in operation, no buses will enter the Carnival area from first thing Sunday morning until the first service on Tuesday morning. On both days bus services begin from Notting Hill Gate in the south and from Harrow Rd (close to Elgin Avenue) in the north. Bike Last year the nearest bike-parking stations - Chepstow Villas and Pembridge Road - were removed for Carnival, so don't rely on being able to park your bike nearby this year. Safety Avoid carrying expensive items, such as jewellery and digital cameras. Take a bag with a secure zip to keep your more valuable possessions in and avoid putting your valuables in your back pocket. Do tell police if you see an incident. Officers will be stationed throughout the Carnival area. Don't try to walk against the flow of the crowd, as you won't get far. Drink plenty of water on the day too, especially if the sun makes an appearance. Children Children's Day on Sunday is recommended for families as the smaller crowds and kid-friendly floats create a fun atmosphere. Arrange meeting points in case you become separated. The smaller the buggy , the better. Ear defenders may be necessary for very young children.
Question: Visitors are warned not to bike to the Carnival because _ .
Options: (A) there are an increasing number of bike thefts there (B) there are no bike-parking stations nearby (C) roads to the Carnival area are closed to bikes (D) they will be charged with extra parking fees
Asnwer: B
Yes
