She wish that he was as easy to please as her mother, who was always delighted with perfumeBesides, shopping at this time of the year was a most disagreeable experience :people trod on your toes, poked you with their elbows and almost knocked you over in their haste to get to a bargain ahead of you.Partly to have a rest, Edith paused in front of a counter where some attractive ties were on display. "They are real silk," the assistant assured her, trying to tempt her. "Worth doubles the price." But edit knew from past experience that her choice of ties hardly ever pleased her father.She moved on reluctantly and then quite by chance, stopped where a small crowd of man had gathered round a counter. She found some good quality pipes on sale-----and the prices were very reasonable. Edith did not hesitate for long: although her father only smoked a pipe occasionally, she knew that this was a present which was bund to please him.When she got home, with her small well-chosen present concealed in her handbag, her parents were already at the supper table. Her mother was in an especially cheerful mood, "Y our father has at last to decide to stop smoking." She informed her daughter.1. Edith's father _______.a. did not like presentb. never got presentc. preferred tiesd. was difficult to choose a present for2. The assistant spoke to Edith because she seemed_______.a. attractiveb. interested in tiesc. tiredd. in need of comfort3. Edith stopped at the next counter_________.a. purposelyb. suddenlyc. unwillinglyd. accidentally4. Edith's father smoked a pipe_______.a. when he was obligedb. on social occasionsc. from time to timed. when he was delighted5. Shopping was very disagreeable at that time of the year because_______.a. customers trod on each other's toesb. customers poked each other with their elbowsc. customers knocked each otherd. customers were doing their shopping in a great hurryPassage B.If the population of the earth goes on increasing at its present rate, there will eventually not be enough resources left to sustain life on the planet. By the middle of the 21st century, if present trends continue, we will have used up all the oil that drives our cars, for example. Even if scientists develop new ways of feeding the human race, the crowded conditions on earth will make it necessary for us to look for open space somewhere else. But none of the other planets in our solar system are capable of supporting life at present. One possible solution to the problem, however, has recently been suggested by American scientist, Professor Carl Sagan.Sagan believes that before the earth's resources are completely exhausted it will be possible to change the atmosphere of V enus and so create a new world almost as large as earth itself. The difficult is that V enus is much hotter than the earth and there is only a tiny amount of water there.Sagan proposes that algae organisms that can live in extremely hot or cold atmospheres and at the same time produce oxygen should be bred in condition similar to those on V enus. As soon as this has been done, the algae will be placed in small rockets. Spaceship will then fly to V enus and fire the rockets into the atmosphere .In a fairly short time, the algae will break down the carbon dioxide into oxygen and carbon.When the algae have done their work, the atmosphere will become cooler, but before man can set foot on V enus it will be necessary for the oxygen to produce rain. The surface of the planet will still be too hot for man to land on it but the rain will eventually fall and in a few yearssomething like earth will be reproduced on V enus.1.Inte long run, the most insoluble problem caused by population growth on earth will probably be the lack of ______.a. foodb. oilc. spaced. resources2.Carl Sagan believes that V enus might be colonized from earth because _____a. it might be possible to change its atmosphereb. its atmosphere is the same as the earth'sc. there is a good supply of water on V enusd. the days on V enus are long enough3.On V enus there is a lot of ________.a. waterb. carbon dioxidec. carbon monoxided. oxygen4.Algae are plants that can____.a. live in very hot temperaturesb. live in very cold temperaturesc. manufacture oxygend. all of the above5.
