材料:
The field current supply in older machines comes from a lower voltage direct current generator or exciter on the same shaft as the alternator. Modern machines however are either statically excited or of the high-speed brush-less type. The exciter is required to operate to counter the effects of power factor for a given load. The power factor is a measure of the phase difference between voltage and current and is expressed as the cosine of the phase angle. With a purely resistance load the voltage and the current are in phase, giving a power factor of one. The power consumed is therefore the product of voltage and current. Inductive or capacitive loads, combined with resistance loads, produce lagging or leading power factors which have a value less than one.
The power consumed is therefore the product of current, voltage and power factor. The alternating current generator supplying a load has a voltage drop resulting from the load. When the load has a lagging power factor this voltage drop is considerable. Therefore the exciter, in maintaining the alternator voltage, must vary with load current and also the power factor. The speed change of the prime mover must also be taken into account.
问题: The word “machines” in the passage refers to _____.
A.the direct current generator
B.the alternating current generator
C.the exciter
D.the prime mover
Which of the following statements is true according to the passage ?
A.With a purely resistance load, the power factor is zero
B.Inductive loads combined with resistance loads produces leading power factors
C.Capacitive loads combined with resistance loads produces lagging power factors
D.With a purely resistance load, the phase angle is zero
When the load has a lagging power factor this voltage drop is considerable. This sentence means that _____.A.with a purely resistance load, the voltage drops too much
B.there is a considerable voltage drop in the capacitive load combined with resistance load
C.when the load is the capacitive load combined with resistance load, the voltage drops to zero
D.when the load is the inductive load combined with resistance load, the voltage drop is fairly large
The exciter must vary with: ① load current ② the power factor, ③ speed change of the prime mover.A.①
B.②
C.①②
D.①②③

What do statistics do for science?
A.They get rid of intuition,
B.They make it more logical.
C.They reduce everything to numbers.
D.They give an idea of the amount of error involved.
Animals, despite their ability to move about and find shelter, are just as much influenced by climate as plants are. Creatures such as the camel and the penguin are so highly specialized that they have an extremely limited distribution. Others, such as bears, are flexible enough to adapt to a broad range of climates. Ocean-dwelling organisms are just as sensitive to climate changes in this temperature and salinity as land animals.
Human beings are among the least specialized of all animals and live almost anywhere. Their clothes and their homes act as a sort of "miniature climate" that can be taken with them everywhere.
According to the passage, which of the following factors most influences where life is found on earth?
A.Climatic conditions.
B.The length of days and nights.
C.Ocean tides.
D.Geographic boundaries.
Plants, even more than animals, must be well adapted to climate in order to survive. They cannot move about or take shelter but must be equipped to endure whatever weather conditions are likely to occur.
In the harsh conditions of tundra, for example, low growing mosses, lichens, and a few flowering plants all hug the ground for shelter from icy winds.

Creatures such as the camel and the penguin are so highly specialized that they have as extremely limited distribution. Others, such as bears, are flexible enough to adapt to a broad range of climates. Oceandwelling organisms are just as sensitive to climatic changes—in this case temperature and salinity (含盐量)—as land animals. Reef corals can survive only in clear warm seawater. Certain foraminifers are so sensitive to changes in their environment that their presence can be taken as an index of sea temperature. Human beings are among the least specialized of all animals and can live almost anywhere. Their clothes and their homes act as a sort of "miniature climate" that can be taken with them everywhere.
Which of the following is neither plant nor animal?
A.Tundra

As the head of the credit department, the credit manager is responsible for seeing that the department operates effectively. He must develop the factor's credit policies in consultation with senior factoring associates, and he is in overall command of everything from credit and collections to bankruptcy and liquidations. If the factor is a commercial bank division, the credit manager is a bank's vice president, and credit policy must also be approved by top management of the bank,
Assisting the credit manager may be several supervisors who have credit responsibilities of their own and who also oversee the analysis and approval of customer orders by the credit specialists. Credit supervisors typically spend about eighty percent of their time handling large customer orders. If a customer order exceeds a supervisor's credit authority, he is responsible for making recommendations to the credit manager. A supervisor also reviews a subordinate' s credit decision if the subordinate is unsure of the extent of the credit risk or if a client questions a particular credit decision.
In extremely large credit exposures, supervisors bear the responsibility for analyzing the credit position of the customers and deciding on credit limits. To do this, they must regularly obtain current data from various credit information sources. They must also have extensive contact with each customer to determine operational performance and progress. Frequently, supervisors are called upon to give advice on what should be done to improve a company' s financial condition. Meeting all these responsibilities requires that each supervisor continuously observe and study the industries with which he is concerned, so that he is capable of anticipating market changes which may affect his accounts.
A supervisor's major challenge is to maintain a fine balance between the demands of clients that all their customer orders be approved and the questionable financial position of some of the customers. In reviewing any credit decision, a supervisor must be capable of weighing a variety of elements, including the possibility of losing the client, the customer' s credit position, and the extent of any possible loss.
What is the main idea of the passage?
A.The credit manager's responsibility.
B.The supervisor's responsibility.
C.The working procedures of a credit department.
D.The command and control in the credit department.

Carl Jung's well-documented break with Sigmund Freud occurred because
of Jung's inability and unwillingness to accept Freud's view of the libido as the
sexual drive of fulfillment. Believing that the libido, or the urge towards life,
extended beyond mere sexuality to a hypothetical elan vital, or life energy
(5) itself, Jung stressed a widened consciousness whereby the individual seeks to
reconcile the opposites of his or her libidial nature that dwell in the conscious as
well as the personal and collective unconscious.
Jung defines this consciousness, moreover, as the center of the ego, and
the personal unconscious as a repository of repressed personal experiences or
(10) complexes that must be made conscious. Finally, the collective unconscious is
an archive of hereditary symbolic archetypes that express themselves in
dreams, fantasies, and actions, and must also be made conscious. Jung
postulated that these archetypal patterns must be integrated into the world of
the ego, which is then forced to acknowledge for these reasons that the ego-
(15) centered consciousness is not really self-sufficient and does not exist
independently and alone, but is guided by an integrating factor not of its own
making.
According to the passage, the collective unconscious and the personal andunconscious have in common which of the following?
A.Both the collective unconscious and the personal unconscious are hereditary, deriving from common cultural experiences, including symbolic archetypes.
B.Both the collective unconscious and the personal unconscious share an extricable link with the conscious that should be made evident.
C.Both the collective unconscious and the personal unconscious contain repressed experiences.
D.Both the collective unconscious and the personal unconscious share a position at the center of the human ego.
E.Both the collective unconscious and the personal unconscious include dreams, fantasies, and actions that should be made conscious.

Task 2
Directions: This task is the same as Task 1. The 5 questions or unfinished statements are numbered 41 through 45.
Climate, more than any other single factor, determines the distribution of life on earth. Climatic boundaries establish the limits within which organisms can survive. Plants, even more than animals, must be well adapted to climate in order to survive. They cannot move about or take shelter but must be equipped to endure whatever weather conditions. In the cold north pole, for example, low growing mosses(苔,藓) all hug the ground for shelter from icy winds.
Animals, despite their ability to move about and find shelter, are just as much influenced by climate as plants are. Creatures such as the camel and the penguin are so highly specialized that they have an extremely limited distribution. Others, such as bears, are flexible enough to adapt to a broad range of climates. Ocean-dwelling organisms are just as sensitive to climate changes in this temperature and salinity as land animals.
Human beings are among the least specialized of all animals and live almost anywhere. Their clothes and their homes act as a sort of "miniature climate" that can be taken with them everywhere.
According to the passage, which of the following factors most influences where life is found on earth?
A.Climatic conditions.
B.The length of days and nights.
C.Ocean tides.
D.Geographic boundaries.
