A growing number of schools across the U.S.are multimedia,history through gamse and math with step-by -step animation of complex problems. As part of a pilot program,Roslyn High School handed out 47 iPads on Dec.20,2010 to the students and teachers in two humanities classes. The school district hopes to provide iPads eventually to all 1,100 of its students. The iPads are to be used in class and at hom during the school year to replace texbooks,allow students to correspond with teachers and tum in papers and homework tasks,and preserve a rocord of student work in digital files. "It allows us to extend the classes beyond _ "said larry Reiff,an English teacher at Roslyn who now posts all his course mateials online. But educators are still divided over whether practices to give every student a laptop have made a difference academically. "Thre is very little evidence that kids learn more,faster of better by using these machines,"said Larry Cuban,a retried professor of eduction at Staford University."IPads are excellent tools to attract kids,but then the fieshness wears off and you eget int hard-core problems of teaching and learning." But school leaders say the iPad is not just a cool new toy but rather a powerful and multifunctional tool with a number of applications,including thousands with educational uses. "If there isn't an application that does something I need ,there will be sooner or later,"said Mr.Reiff,who said he now used an application that includes all of Shakespare's plays. Question: The school leaders tink highly of the iPad mainly because it is  _  . - cool and interesting - powerful and helpful - multifunctional and expensive - attractive and vivid
powerful and helpful

Read the following article and select the best answer. Article: A man stayed in his house as a flood engulfed   his town. Two men in a boat came to his house and offered to take him to safety. "No, thank you," said the man, "God will help me." As the waters rose, the man retreated   to the second floor of his house. Now, two men in a motorboat came by and offered to rescue him. Again, the man refused, saying, "No, thank you. God will help me. " As the waters rose still higher, the man retreated again to the rooftop of his house. A plane came by, and someone inside it threw down a rope, urging   the man to grab   it and be pulled up into the airplane. Once more, the man declined and said, "No, thank you. God will help me. " Just then a powerful voice called out to the man, "You idiot! I sent you a boat, a motorboat and now a plane. What more do you want me to do?" Question: Why didn't the man enter the rowboat at first? - Because he didn't know the men in the boat. - Because he thought he could retreat to a higher place. - Because he was sure God would help him. - Because he was sure he could take himself to safety.

Ques: Read the following article and select the best answer. Article: Drawings of human colonies on other planets often picture the entire community under a glass or plastic bubble. The bubble is intended to create an atmosphere with adequate oxygen and other essential elements. But similar bubble-like structures have also been constructed on earth. One of the most famous, and controversial, is a site in the Arizona desert. Biosphere 2, as it is called, was built not far from Tucson in 1984 and is now run by Columbia University. This huge(7,200,000-cubic-foot)glass and steel construction contains several separate ecosystems, including a desert, a rain forest, and a 900,000-gallon "ocean." The climatic conditions-humidity, temperature, air quality-are regulated by sensors and can be adjusted as needed or desired. For example, a rainstorm can be created to increase the humidity. The adjustable features of Biosphere 2 make it an ideal location to perform experiments to help determine the effects of such climatic changes as global warming. The current conditions at Biosphere 2 are vastly different from those in 1993, when eight people who had moved into the environment with great fanfare two years earlier moved out in failure. Though promising to be self-sufficient , these "colonists" had so much trouble regulating the environment that they reportedly had food smuggled into them. Oxygen levels became dangerously low; most plants and animals died. In taking over the unsuccessful site, Columbia hopes to erase its notorious past by focusing on small research projects that gradually answer some of Biosphere 1's -- that is, Earth's most basic environment questions. Question: The writer helps you understand what Biosphere 2 is like by   _  . - comparing its features with those of an outer space biosphere - explaining the process by which it was constructed - referring to an interview with one of former inhabitants - describing its appearance and conditions
Ans: describing its appearance and conditions


Read the following article and select the best answer. Article: Like lots of other girls and boys,when Lisa Cao was a kid,she used to watch the Olympics. "I always wanted to be good at sport and I found athletic potential in my body", the New York City citizen tells her friends. But there was no sport available so she took up piano lessons. Then,at the age of 15,she decided to drop the lessons and put her athletic potential to the test with running. At age 18,Lisa Cao ran her first-ever marathon in New York City. And now,the 27-year-old  has 54 marathons (26. miles) and ultramarathons (100miles) under her belt. What does it take to be an ultramarathoner? A lot of devotion,even when difficulties occur sometimes. "Making time for running is really hard when life is so busy," she says. "There's a big work-life balance that I have to keep. I have to wake up earlier on the weekends. And oh,the potential for excuses! With NYC's wild winters as of late,it's easy to blame the weather,roll over in bed and put off a solid run. I have a fix for this,though," she says. "Cute clothes. With the horrible weather, I bought cute clothes as motivation to run and actually wear them. " While she's training during low season in the winter,Lisa Cao tries to run a "base" of 20 to 30 miles per week to stay prepared. During high season in the spring and summer,she'll run around 30 to 40 miles,but she also gets a lot of quality miles from her races.
