填空题Hitler wanted to invade England (56) could not do so until the RAF was destroyed. In August 1940 the Germans began daylight bombing against English ports and airfields and in September (57) London and other cities. The plan was to draw out the English fighters and destroy them. (58) the RAF was very small, the people of England were praying for the fighter pilots and believing (59) an English victory. The Nazis started losing a great (60) of their airplanes and changed (61) to night bombing by the end of September. The people of London were also in the front lines (62) they couldn't fly fighters and smash the enemy planes. They had to dig quickly in cellars to (63) their friends who had been buried underneath the wreckage. They had to put out endless fires. They had to stand (64) and take whatever the enemy threw at them. People understood that Britain's fate depended on the resolution of the common people, and those watching for fire on the roofs. This continued (65) the Nazis were finally defeated by the Allied nations.

填空题One word that you might have learned when you were studying about sound is frequency. Frequency means 1 fast the sound wave vibrates. Faster vibrations produce 2 pitched sounds. The notes in a musical scale indicate the 3 or frequency of the sound. 4 word that can describe a sound is intensity. Intensity 5 to the amount of energy in a sound wave, and it 6 a sound"s loudness. Printed music will often include notes about how loud or 7 to play each section of the music. Timbre is another 8 used to describe musical sounds. It describes how the same note will have 9 sounds when played 10 different instruments. For example the same note may sound soft and pretty when played on a flute, 11 strong and brassy when played on a trumpet. The timbre of a note comes from both the actual note 12 is played 13 also its overtones, 14 are other higher and lower sounds that are produced 15 the same time.

填空题A. The new Minneapolis bridge joins a handful of "smart" bridges that have built-in sensors to monitor their health. B. The kilometers of wire needed to connect sensors to central computers can add significantly to the system's cost, according to Jerome Lynch of the University of Michigan, Ann Arbor. C. By 2025 all bridges in America will have been equipped with this advanced technology. D. A continuous skin would solve this problem. E. In the wake of the catastrophe, there were calls to harness technology to avoid similar mishaps. F. Engineers then installed additional weights as dampeners. When an eight-lane steel-truss-arch bridge across the Mississippi River in Minneapolis collapsed during the evening rush hour on August 1st 2007, 13 people were killed and 145 were injured. There had been no warning. The bridge was 40 years old but had a life expectancy of 50 years. The central span suddenly gave way after the gusset plates that connected the steel beams buckled and fractured, dropping the bridge into the river. (71) The St. Anthony Falls bridge, which opened on September 18th, 2008 and replaces the collapsed structure, should do just that. It has an embedded early-warning system made of hundreds of sensors. They include wire and fibre-optic strain and displacement gauges, accelerometers, potentiometers and corrosion sensors that have been built into the span to monitor it for structural weaknesses, such as corroded concrete and overly strained joints. (72) Another example is the six-lane Charilaos Trikoupis bridge in Greece, which spans the Gulf of Corinth, linking the town of Rio on the Peloponnese peninsula to Antirrio on the mainland. This 3km-long bridge, which was opened in 2004, has roughly 300 sensors that alert its operators if an earthquake or high winds warrant it being shut to traffic, as well as monitoring its overall health. These sensors have already detected some abnormal vibrations in the cables holding the bridge. (73) The next generation of sensors to monitor bridge health will be even more sophisticated. For one thing, they will be wireless, which will make installing them a lot cheaper. (74) Dr Lynch is the chief researcher on a project intended to help design the next generation of monitoring systems for bridges. He and his colleagues are also looking at how to make a cement-based sensing skin that can detect excessive strain in bridges. Individual sensors, says Dr Lynch, are not ideal because the initial cracks in a bridge may not occur at the point the sensor is placed. (75) He is also exploring a paint-like substance made of carbon nanotubes that can be painted onto bridges to detect corrosion and cracks. Since carbon nanotubes conduct electricity, sending a current through the paint would help engineers to detect structural weakness through changes in the paint's electrical properties.

填空题"Humanism" has used to mean too many things to be a very satisfactory term. 57. Nevertheless, and in the lack of a better word, 58. I shall use it here to explain for the complex of attitudes which this discussion has undertaken to defend. 59. In this sense a humanist is anyone who rejects the attempt to describe or account of man wholly on the basis of physics, chemistry, and animal behavior. 60. He is anyone who believes that will, reason, and purpose are real and significant: that value and justice, are aspects of a reality called good and evil and rests upon some foundation other than custom; 61. that consciousness is so far from a mere epiphenomenon that it is the most tremendous of actualities; 62. that the unmeasured may be significant; or, to sum it all up, 63. that those human realities which sometimes seem to exist only in human mind are the perceptions of the mind. 64. He is, in other words, anyone who says that there are more things in heaven and earth than those dreamed of in the positivist philosophy. 65. Originally, to the sure, the term humanist meant simply anyone who thought the study of ancient literature his chief concern. Obviously it means, as I use it, very much more. 66. But there remains nevertheless a certain connection between the aboriginal meaning and that I am attempting to give it. 67. Because those whom I describe as humanists usually recognize that literature and the arts have been pretty consistently "on its side" and 68. because it is often to literature that they turn to renew their faith in the whole class of truths which the modem world has so consistently tended to dismiss as the mere figments of a wishful thinking imagination. 69. Insofar as this modern world gives less and less attention to its literary past, insofar as it dismisses that as something outgrow and 70. to be discarded as much as the imperfect technology contemporary with it has been discarded, 71. just to that extent it facilitate the surrender of humanism to technology. 72. The literature is to be found, directly expressed or, 73. more often, indirectly implied the most effective correction to the views now most prevalent among the thinking and unthinking. 74. The great imaginative writers present a picture of human nature and of human life which carries conviction and thus giving the lie to all attempts to reduce man to a mechanism. Novels and poems, and dramas are so persistently concerned with the values which relativism rejects that one might even define literature as the attempt to pass value judgments upon representations of human life. 75. More often than not those of its imaginative persons who fail to achieve power and wealth are more successful than those who do not--by standards which the imaginative writer persuades us to accept as valid.
