阅读类训练(6)阅读理解。阅读下列短文, 从给的四个选项 (a、b、c和d) 中, 选出最佳选项。today, ultrasonic(超声的) waves are being put to work in laboratories and factories. if an ultrasound generator is placed in a liquid, the waves move the liquid back and forth hundreds of thousands of times each second. this causes materials to mix quickly or to dissolve(使分解,使溶解) in liquids. paint manufacturers(制造商) use ultrasound to do a better job of blending colors. the companies that make film for your camera find that mixing chemicals by the use of sound waves will produce a more sensitive film. the new lightweight(轻量的) type of washing machine uses ultrasonic waves to get clothes clean. its special ultrasound generator is put into a pail of soapy water containing the soiled clothes. the sound waves drive the soapy water back and forth through the cloth so fast that everything is soon clean. there is also a new kind of dishwasher that works in much the same way. ultrasonic waves can shake a liquid so fast that tiny holes form all through it. the liquid is actually torn apart by this action. almost as soon as these holes are made, they fall together again. the result is a powerful pounding action. in the dairy industry this is used for the double purpose of making homogenized(使均匀,使匀质) milk and sterilizing(使无菌) it at the same time. if you look at some raw milk with a microscope, you find that it is made up of little drops of butter fat floating around in a watery liquid. in order to make milk easier to digest, these fat droplets(微粒) may be broken up by forcing the milk through very small openings. the result is called homogenized milk. when the ultrasonic method is used, the sound waves not only break up the droplets but also kill the germs in the milk by pounding them to pieces. (from )1. why does a paint manufacturer use ultrasound to do a better job of blending colors?a. because it is cheap to use ultrasound to blend colors.b. because the waves move the liquid so quickly that it can make materials mix quickly or dissolve in liquids.c. because they can mix chemicals by the use of sound waves.d. because the waves can clean the paint.2. what properties does ultrasound wave have?a. homogenizes and sterilizes the milk. b. mix materials and break droplets.c. kill germs and sterilize milk. d. move liquids quickly.3. what exists in the raw milk?a. little drops of butter fat. b. small holes.c. fat droplets and germs. d. chemicals.4. where is ultrasound wave not used? a. in the paint manufacture. b. in the shop mixing bread flour.c. in the film-making company. d. in the dairy industry.1. b 事实细节题。根据其上句 this causes materials to mix quickly or to dissolve(使分解,使溶解) in liquids 可知,答案选 b。2. d 事实细节题。根据文章最后一段的第 1 句 ultrasonic waves can shake a liquid so fast that tiny holes form all through it可知,答案选 d。3. c 事实细节题。根据文章最后一段的内容,特别是最后一句 when the ultrasonic method is used, the sound waves not only break up the droplets but also kill the germs in the milk by pounding them to pieces 可知,答案选 c4. b 推理判断题。根据文章第 1 段最后提到的 paint manufacturers(制造商)以及the companies that make film 两句排除选项 a、c,根据第 3 段第 5 句的 in the dairy industry this is used for 排除选项 d,从而得出答案是 b。第一部分完形填空完形填空训练阅读下面短文,掌握其大意,然后从31-50各题所给的四个选项(a、b、c和d)中,选出最佳选项,并在答题纸上将该选项标号涂黑。 its not the goodbye that hurts, but the flashbacks that follow my mother suffered with alzheimers disease (老年痴呆症) during

keep1.d从上下文判断这里不是说全亚洲有16人感染禽流感,而是16人由于禽流感而死去。2.c下文说“但是13个省市区报道有家禽感染”,与此对应,这里说没有出现人员被感染的情况。3.b这里说的是据报道这些地区有家禽感染禽流感。4.a如何预防和控制这一疾病,这仍然是我们的一个艰巨任务。5.a从上下文判断这里表示转折关系,尽管任务艰巨,但是我们充满信心。6.d用stop/prevent sb (from) doing sth,或keep sb from doing sth。keep sb doing sth表示“让某人持续做”显然不符合语境。7.b这里讲述人们采取的一系列措施,一方面另一方面,用副词meanwhile表示与此同时。8.c不是日常的控制,而是全国各地的疾病动态的报道。9.c这里说增加疫苗的生产,用increased表示增加产量。10.a动物感染禽流感。11.d这里说人感染禽流感都是从家禽感染的。用catch (the illness)表示感染某疾病。12.c从上下文的连贯用c,尽管没有证据,但是事实证明人可以互相传染该疾病。13.b既然没有直接的证据,那么这只是人们的猜测,用情态动词might表示微小的可能性。14.b最大的问题/威胁。15.a既然是create(创造),那么一定是一种新的疾病。16. d与上文呼应,这里说的都是全球范围内的疾病传播和控制。17.d在时常出售鲜活家禽。正是鲜活的家禽传染疾病。18.b这就加大了人感染疾病的几率19.a要预防和控制疾病就必须有更科学的喂养和销售方式。20.b要改变原来的生活方式和喂养动物的方法。第二部分阅读理解训练阅读理解训练nasa is moving ahead with plans to put a long-armed lander on mars icy north pole to search for clues for water and possible signs of life.the $386 million phoenix mars is planned to touch down in the martian arctic in 2008. the stationary probe will use its robotic arm to dig into the icy land and pick up soil samples to analyze. in 2002, the mars odyssey orbiter spotted evidence of ice-rich soil near the arctic surface. scientists hope the phoenix mission will find clues to the geologic history of water on the red planet and determine whether microbes existed in the ice.phoenix will be the first mission of the mars scout program, a renewed, low-cost effort to study the red planet. “the phoenix mission explores new territory in the northern plains of mars analogous to the permafrost regions on earth,” peter smith said. true to its name, phoenix rose from the ashes of previous missions. the lander for phoenix was built to fly as part of the 2001 mars surveyor program. but the program broke down after the well-known disappearance of the mars polar lander in 1999. the polar lander lost contact during a landing attempt near the planets south pole after its rocket engine shut off prematurely, causing the spacecraft to fall about 130 feet to almost certain destruction. the phoenix probe had been in storage at a lockheed martin clean room in denver before it was reused for its present mission. it will carry science instruments that were designed for
