[单项选择]Passage Two

The vegetative forms of most bacteria are killed by drying in air, although the different species exhibit pronounced differences in their resistance. The tubercle bacillus is one of the more resistant, and vibrio cholera is one of the more sensitive to drying. In general, the encapsulated organisms are more resistant than the non-encapsulated forms. Spores are quite resistant to drying; the spores of the anthrax bacillus, for example, will germinate after remaining in a dry condition for ten years or more. The resistance of the pathogenic forms causing disease of the upper respiratory tract is of particular interest in connection with airborne infection, for the length of time that a droplet remains infective is a result, primarily, of the resistance of the particular microorganism to drying.
Tuberculo
A. spores are resistant to drying
B. the causative organism is encapsulated.
C. droplets of sputum remain infective for a long time due to the resistance of the organisms to drying.
D. none of these.

[单项选择]Passage Two

Most new words are made up from other earlier words; language-making is a conservative process, wasting little. When new words unfold out of old ones, the original meaning usually hangs around like an unrecognizable scent, a sort of secret.
There are two immense words from Indo-European, gene and bheu, each a virtual anthill in itself, from which we have constructed the notion Of everything. At the beginning or as far back as they are traceable, they meant something like being. Gene signified beginning, giving birth, while bheu indicated existence and growth. Gene turned itself successively into kund jaz (Germanic) and gecynd (Old English), meaning kin or kind. Kind was at first a family connection, later an elevated social rank, and finally came to rest meaning kindly or gentle. Meanwhile, a branch of gene became the Latin gens
A. how to coin new words
B. where to trace the origin of language
C. the evolution of words
D. language and nature

The most interesting architectural phenomenon of the 1970’s was the enthusiasm for refurbishing older buildings. Obviously, this was not an entirely new phenomenon. What is new is the wholesale interest in reusing the past, in recycling, in adaptive re- habilitation. A few trial efforts, such as Ghirardelli Square in San Francisco, proved their financial viability in the 1960’s, but it was in the 1970’s, with strong government support through tax incentives and rapid depreciation, as well as growing interest in ecology issues, that recycling became a major factor on the urban scene.
One of the most comprehensive ventures was the restoration and transformation of Boston’s eighteenth century Faneuil Hall and the Quincy Market, designed in 1824. This section had fallen on hard times, but beginning with the construction of a new cit
A. The architectural phenomenon of the 1970’s.
B. Tile architectural style from 1824 to 1970’s.
C. In the 1970’s, recycling old buildings became famous.
D. During the 1970’s, old buildings in many cities were recycled for modern use.

[单项选择]Passage Two

The two claws of the mature American lobster are decidedly different from each other. The crusher claw is short and stout; the cutter claw is long and slender. Such bilateral asymmetry, in which the right side of the body is, in all other respects, a mirror image of the left side, is not unlike handedness in humans. But where the majority of humans are right-handed, in lobsters the crusher claw appears with equal probability on either the right side or left side of the body.
Bilateral asymmetry of the claws comes about gradually. In the juvenile fourth and fifth stages of development, the paired claws are symmetrical and cutterlike. Asymmetry begins to appear in the juvenile sixth stage of development, and the paired claws further diverge toward well-defined cutter and crusher claws during succeeding stages. An intriguing aspect
A. The loss of a claw during the third or earlier stage of development.
B. The lose of claw during the fourth or fifth stage of development.
C. The loss of a claw during the sixth stage of development.
D. Development in an environment devoid of material that can be manipulated.
