Howard Dill is a giant among giant pumpkin growers. He grew world champion pumpkins for four years running,from 1979 to 1982, and missed winning the fifth year by only 5 pounds. Today, his Dill Atlantic Giant seeds are sold worldwide to more than 50 seed companies. The pumpkins grown from his Dill Atlantic Giant seeds commonly weigh in at over 1,000 pounds. "I don't have any training in genetics ; it was all trial and error," Dill says. He got his love of pumpkins from his father and has enjoyed growing them for years. Dill still grows giant pumpkins, but not for competition. In the fall, visitors come to enjoy the pumpkins on his 90-acre farm in Nova Scotia, Canada. He plants ten acres of pumpkins for Halloween and two acres of giant pumpkins. One of giant pumpkins was recently baked into 442 pumpkin pies and sold at $5 each for charity. It you want to try growing a giant pumpkin, Dill recommends starting with a soil test and then adding fertilizer as needed. Plant the giant pumpkin seed. A giant pumpkin can gain 15 to 20 pounds a day, so careful watering--every day or two--is necessary. You should wait about 130 days until the pumpkin matures and then you can harvest it. Dill's favorite pumpkin set the Guinness Book record in 1981. It weighted 493.5 pounds. "I've grown them larger since, but that one meant a lot," he remembers. "I never would have imagined ten years ago that there would be a 1,000-pounder, but there are many of them now," says Dill. The 2006 world record holder is Larry Checkon of Pennsylvania. He grew a 1,469 pounder. Dill says, "These world champions are grown from my seeds, so I feel like a winner right along with them." What can we learn about the world champion pumpkin of 1983? A) It weighed over 1,000 pounds. B) It was missing after the competition. C) It was 5 pounds heavier than that of 1982. D) It was 5 pounds heavier than Dill's biggest one that year.

The surprising experiment I am about to describe proves that air is all around you and that it presses down upon you. Air pressure is a powerful force. When you swim underwater, you can feel water pushing on your body. The air all around you does the same. However, your body is so used to it that you do not notice this. The pressure is caused by a layer of air called the atmosphere. This layer surrounds the Earth, extending to about five kilometers above the Earth's surface. The following experiment is an easy one that you can do at home. But make sure that you are supervised , because you will need to use matches. Now for the experiment. What you need * hard-boiled egg without the shell * A bottle with a neck slightly smaller than the egg * A piece of paper * A match Method 1) Check that the egg will sit firmly on the neck of the bottle. 2) Tear the paper into pieces and put them into the bottle. 3) Light the paper by dropping a burning match into the bottle. 4) Quickly sit the egg on the neck of the bottle. Result Astonishingly, the egg will be sucked into the bottle. Your friends will be amazed when you show them the experiment. But be careful when you handle matches. Why it happened? As the paper burns, it needs oxygen and uses up the oxygen (air) in the bottle. The egg acts as a scale in the neck of the bottle, so no more air can get inside. This reduces the air pressure inside the bottle. The air pressure must equalize, so more air from outside must enter the bottle. The outside air presses against the egg, and then the egg is pushed into the bottle! This proves that air is all around and that it is pressing down on us. The experiment is carried out to prove _ .. A) water pushes on your body when you swim underwater B) the earth is surrounded by a layer of air called the atmosphere C) the pressure of air around us has a powerful force D) the air pressure is not equalized around us

Q: One period of our lives when better results are demanded of us is, strangely enough, childhood. Despite being young we are expected to achieve good grades, stay out of trouble, make friends at school, do well on tests, perform chores at home and so on. It's not easy. Likeable children enjoy many advantages, including the ability to deal more easily with stresses of growing up.In her bookUnderstanding Child Stress, Dr. Carolyn Leonard states that children who are likeable and optimistic are able to gain support from others. This leads to focus and resilience , the ability to recover from or adjust early to life stress. Much research shows that resilience has enabled children to succeed in school, avoid drug abuse, and develop a healthy self-awareness . Why does a likeable child more easily handle stress and do better in his or her life? Because likeability helps create what's known as a positive feedback loop . The positive feelings you want to see in other people are returned to you, creating constant encouragement and motivation to deal with the daily stress of life. This feedback loop continues into adulthood. To return once again to the example of teaching, learning becomes easier with a likeable personality. Michael Delucchi of the University of Hawaii reviewed dozens of studies to determine if likeable teachers received good ratings because of their likeability or because they in fact taught well. Delucchi found that "Students who perceive a teacher as likeable, in contrast to those who do not, may be more attentive to the information that the teacher delivers and they'll work harder on assignments, and they will learn more." You may have noticed this pattern in your own life when you try to give some advice. The more positive your relationship with that person, the more he or she seems to listen, and the more you feel certain that that person has heard you and intends to act on your words. The passage aims at proving that _ . A) likeable people give better advice B) likeable people do better in their childhood C) social creatures enjoy more advantages D) likeable people do better in life generally

"Earthquake!"The word flashed in my brain.A roaring sound filled my ears.I tried to slide beneath my desk.The desk did a wild tap dance,slipping and sliding towards the centre of the room.I twisted my body and grabbed at the windowsill behind me,somehow kicking free of my dancing chair.I tried to stand.My legs skated away as if on a bucking escalator. My fingers shook,grasped and held the windowsill tightly.Somewhere through the roar sounded the terrified scream of some wounded animal.I looked behind me and tried to steady my gaze on the other kids but the scene was a dizzy nightmare.Some of the class were sitting in the middle of the room,surrounded by chairs and desks.One girl was screaming.A boy was trying to claw his way across the floor to the door in a crazy overarm crawl. My grip froze me to the windowsill. I cried aloud,"I'm going to die.I'm going to die.Save me,I'm not ready to die,I'm not ready!" I hunched forward on my knees and pressed my face against my clenched fingers.I looked at the backs of my fingers and stupidly noticed the fragile pale hairs growing out of the pores.The fingers would soon cease to exist.Somehow the impending horror of my death was too terrible to even cry about. Suddenly,I became aware that the rocking had ceased.Perhaps I wasn't going to die. At the end of the passage there is a feeling of _ . A) panic B) hope C) sorrow D) excitement
