Ques:Watson entered Mr. Smith's office. The Boss was a hard man. He fired people who didn't do well without giving them a second chance. "Watson," said Mr. Smith, "this past year your department hasn't earned money. We're going to _ that department. It's finished. I' m sorry, --but you'll have to go." "But, sir--if I just had a little more time. For the moment I need the job to keep my son at Riverside School." "What's that!" said the Boss. "Riverside! I didn't know you had a boy there. That's an expensive school for a man with your salary." "I know, sir. But he likes it there so much! He's a star trackman  and the best boxer in the school. The boys call him Champ  there." The Boss sat perfectly still for a long time--a faraway   look in his eyes. Then, suddenly, he said, "We've got to close your department, Watson. But you'll take over a new job in another department. It means longer hours--maybe more pay. Now get out. You're here for life." Watson got out, with surprise in his face. Then the Boss took a letter from the top drawer of his desk. It was Herbie's last letter from Riverside School --written a few days before he died. He had read it over and over again with sick pain. The letter read: I can't say the boys here are any nicer to me than the others were. I guess it's the same everywhere when you're a cripple  . But don't worry about me, Dad. They've got a good chemistry department here. And there's one boy here who is really great. He's a track star and boxing champ and just tops in chemistry. The boys call him Champ. He made them stop throwing my books around. And he knocked a boy down who hit me. He is the best friend I ever had. Dad, when I grow up, I want to do something for Champ. Something big--that he won't even know about. Your son,   Herbie It can be inferred from the text that Champ is  _  . A) Watson' s son B) Mr Smith' s son C) a teacher of Mr Smith's son D) the son of Mr Smith's friend

Ques:It's so difficult to follow the _ of a 2-year-old. One moment he's beaming and friendly; the next he's sullen and weepy, often for no apparent reason. These mood swings, however, are just part of growing up. They are signs of the emotional changes taking place as your child struggles to take control of actions, impulses, feelings and his body. At this age, your child wants to explore the world and seek adventure. As a result, he'll spend most of his time testing limits, his own, yours and his environments. Unfortunately, he still lacks many of the skills required for the safe accomplishment of everything he needs to do, and he often will need you to protect him. When he oversteps a limit and is pulled back, he often reacts with anger and frustration, possibly with a temper tantrum  . He may even strike back by hitting, biting and kicking. At this age, he doesn't have much control over his emotional impulse  . So his anger and frustration tend to erupt suddenly in the form of crying, hitting or screaming. It's his only way of dealing with the difficult realities of life. He may even act out in ways that unintentionally harm himself or others. It's all part of being 2. It's not uncommon for toddlers to be angels when you're not around, because they don't trust people enough to test their limits. But with you, your toddler will be willing to try things that may be dangerous or difficult, because he knows you'll rescue him if he gets into trouble. Whatever protest pattern he has developed around the end of his first year will probably persist for some time. For instance, when you're about to leave him with a sitter, he may become angry and throw a tantrum in anticipation   of the separation. Or he may cry and cling to you. Or he could simply become subdued and silent. Whatever his behavior, try not to overreact by scolding or punishing him. The best tactic  is to reassure him before you leave that you will be back and, when you return, to praise him for being so patient while you are gone. Take comfort in the... The "ups and downs" (Para. 1) of a 2-year-old refers to   _  . A) his falling down and standing up B) his successes and failures in doing things C) his good and bad traits D) his mood swings

Ques:The speed of light is often called a"constant ". New experiments show that may not be true, even within a vacuum. Sometimes, light slows a bit. The new research is"very impressive work", Robert Boyd toldScienceNews.An optical physicist at the University of Rochester in New York, he did not work on the study. He speaks of the new finding:"It's the sort of thing that's so obvious; you wonder why you didn't think of it first." Light travels as particles and as waves. Photons are the name given to those particles that represent the smallest possible amount of light. At their fastest, photons travel nearly 300 million meters (almost 1 billion feet) in a single second. That's fast enough to get to the moon and back in about 2.6 seconds. Scientists had long known, though, that they could slow light photons down by shining them through a material such as glass or water. Still, light moving through a vacuum has usually been assumed to move at a peak speed. That would seem to make sense. After all, a vacuum is a space with nothing in it to slow light down. In a new study, however, scientists show that even racing through a vacuum, light can slow. So the speed of light is more of a universal speed limit than an   rule for how fast photons travel, the new data suggest. Miles Padgett led the new study. As an optical physicist, he works at the University of Glasgow in Scotland. He and his colleagues showed that the key to slowing light is to change the shape of a light wave. Padgett described how they did this in a paper published online January 22 inScience. His team raced a pair of photons. One traveled unchanged through a cable made from optical fibers. The other passed through a pair of devices that acted like lenses. A lens changes light: It can focus a spread-out beam of light on a point, for instance. The second photon passed through one device that changed the shape of its waveand another that changed it back to its original form. The first photon won the race. The second photon came in a tiny bit later, several... The most important factor in changing the speed of light is to transform    . A) the shape of a light wave B) the length of a light wave C) the direction of a photon D) the structure of a photon
