（A）Outside her shabby cottage, old Mrs. Tailor was hanging out laundry on a wire line, unaware that some children lay hidden in the leaves of a nearby tree watching her every move. They were determined to find out if she really was a witch.They watched as she took a broomstick to clean the dirt from her stone steps. But, much to their disappointment, she did not mount the broomstick and take flight. Suddenly, the old lady’s work was interrupted by the cackling of her hen—a signal that an egg had been laid in the warm nest on top of the haystack.The old broomstick was put aside as she hobbled off towards the haystack followed by Sooty, a black cat she had rescued from a fox trap some time back. With only three legs, it was hard for Sooty to keep up with the old lady. The cat provided proof—the children were sure that only a witch could own a black cat with three legs.There, standing on a wooden box, was Mrs. Tailor, stretching out to gather her precious egg. Taking the egg in one of her hands, she began to climb down when, without warning, the box broke and the old lady fell.“We have to got and help her,” whispered Amy.“What if it is a trick?” replied Ben.“Don’t be silly, Ben. If she were a witch, she would have turned us into frogs already,” reasoned Meg. “Come on Amy, let’s go.” The girls climbed down the tree and ran all the way to the haystack.Approaching carefully, they could see a wound on the old lady’s face. She had knocked her hea d on a stone and her ankle was definitely broken. “Go and get Dad,”Amy yelled to her brother. “Tell him about the accident.”The boys did not need another excuse to leave. They ran as fast as thy could for help, hoping that Mrs. Tailor would not wake and turn the girls into frogs.56. Were the children hiding in the tree?A.

When you swim underwater, you can feel water push down 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 foe the experiment！What you need·A hard-boiled egg without the shell·A bottle with a neck slightly smaller than the egg·A p iece of paper·A matchMetheod1） Check that the paper will sit firmly on the neck of the bottle.2） Tear the paper into strips and put the strips 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.ResultAstonishingly, 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 happenedAs the paper burns, it needs oxygen and uses up the oxygen （air） in the bottle. The egg acts as a seal 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 pressure against the egg and then the egg is pushed into the bottle! The proves that air is all around and that it is pressing down on it.60. Why is there the need to take care when you are doing the experiment?A. The bottle could break.B. You need to light the paper with a match.C. The egg needs to be shelled.D. The egg has to be perfectly placed on the neck of the bottle.61. In the experiment, the burning inside the bottle can___.A. equalize the air pressure inside and outsideB. make a seal in the neck of the bottleC. finish up the oxygen inside the bottleD. produce more oxygen inside the bottle62. How did the egg put into the bottle？A. The oxygen inside the bottle sucked the egg in.B. It became salt without the shell.C. The neck of the bottle was wide enough.D. The outside air pressure forced it into the bottle.63. The experiment is carried cut 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.第二天完形填空（共20小题；每小题1.5分, 满分30分）When Alice started to cycle home from Jenny’s house, she wasn’t nervous.
