[Q]: Article: A recent study suggests that teens' relationship with parents, friends and teachers may have a lot to do with why they don't get a good night's sleep. David Maume, a sociologist and sleep researcher, analyzed federal health data, which interviewed 974 teenagers when they were 12, and then again at 15. He found that family dynamics have much to do with how well kids sleep. Teens, who had warm relations with their parents and felt like they could talk to them or their parents were supportive of them, tended to sleep better. However, families that were going through a divorce or a remarriage tended to affect teens' sleep. And problems at school also affected teens' sleep. Feeling safe at school and having good relations with teachers tended to promote better sleep. As did good relationships with friends. Kids who took part in sports or other positive social activities or shared similar academic goals with their friends were also more likely to get a good night's sleep. These add up to what makes lots of sense: a general feeling of well-being helps teens sleep. If we're happy and contented, we're much more likely to sleep better than if we're sad and anxious. Now, of course, teens can hardly resist being drawn to their computers and social networking. Maume also found that when parents were strict not only about bedtime, but also about limiting technology, kids slept better. It's a finding that seems obvious, but parents really do matter when it comes to health habits of their teenagers. Clearly, teenagers aren't getting 9 to 10 hours a night, which puts them at risk for all the consequences of lack of sleep, including poor academic performance, colds and stress.
Question: What is the passage mainly about?
Options: (A) Teens' sleep is linked to their relationship with people around them. (B) Lack of adequate sleep puts teens at risk of many bad consequences. (C) Modern technology has something to do with teens' sleep problems. (D) It is necessary for teens to join in sports and positive social activities.

[Q]: Article: An air of anxious uncertainty spread throughout the small Indian camp as the sun dawned that morning. Some braves gathered beside a smoking campfire. Murmuring sounds could be heard as they talked quietly. Women nervously performed their domestic tasks, preparing a small meal. Several sad, old men sat mute, their morale very low. The camp was pitched at the edge of a deep valley--so deep that one could barely see the calm water at the bottom. The Indians had been taken by surprise and were surrounded and attacked by enemy forces. They fought bravely, but they were degraded by defeat. Their homes were destroyed. Those who had survived had been pursued by the enemy. The chase had lasted for days. Persuaded by their leaders to press on, they had made a wrong turn. Their _ journey ended at the edge of a valley--a desperate situation. Before them was a great hole in the earth. Behind them was the enemy. No wonder they were frozen with fear. Where could they go? Just when no choice seemed available to them, several young braves ran into camp. With great excitement they reported seeing a stone bridge across the valley, just a short distance from camp. Most of the tribe discounted this wild story. However, a few hurried to the spot to see for themselves. Seeing was believing! Indeed there was a stone bridge, great enough to accommodate many people and their horses. Without hesitation the people gathered up their children and the belongings they had and hurried across the bridge. Enemy braves watched from a nearby cliff. It was obvious that the Great Spirit was on the side of the defeated. The enemy did not follow. Safe on the other side of the valley, the wanderers thanked the Great Spirit for providing the vital link. They had escaped their enemies. For hundreds of miles around, Indian people heard about the miraculous stone bridge. From this incident it was clear that the Great Spirit defends weak people. Many came from near and far to see the magnificent stone bridge. You, too, can see this bridge and even ride across it in a car--in southwestern Virginia.
Question: Faced with the desperate situation, some Indians in the camp _ .
Options: (A) tried to persuade their leaders to give in to the enemies. (B) were still as cheerful as before. (C) still remained fearless and loyal to their leaders. (D) were in very low spirits.
Asnwer: C
[A]: No

[Q]: Article: When I was ten my dad helped me buy my first ten-speed bicycle from Allen. I put up $60 of my grass cutting and snow shoveling money and my dad put up the other half I would pay him back over the next six months. Although it was not in the latest style, it was my ticket to the adult world. I spent that summer and autumn riding happily. My sister Liz, a prisoner of her five-speed bicycle, never had a chance to keep up. Just before the Christmas deadline to pay my dad back, we were hit with several snowstorms. This allowed me to shovel enough driveways to pay off my debt. I was now officially a bike owner; it was a feeling unlike any other. On that Christmas morning, my dad gave me a used portable record player. I was excited. However, my joy was short-lived after my dad called my sister to the kitchen. "We have one more gift for you." he said as he opened the door that led to the garage. There, on the steps, stood a new ten-speed bicycle. "It's not fair," I complained. "I worked so hard for my bike and it's not even new. Then Liz gets a new bike. She didn't have to do anything for it. " My dad smiled. "She didn't have to do anything for it because it' s not really for her," he said. What did that mean? I didn't want her bike. By spring Liz and I were riding all over town together now that she could keep up. As we grew, Liz and I became true friends. Still I wasn't smart enough to figure out what my dad meant until years later. That new bike was not a gift for Liz -- it was a gift for me. He'd given me the gift of my sister's company, the ability to stay together rather than drift apart in the face of my ability to travel. He gave me my best friend.
