[单项选择]Passage 1
A person may have an idea about himself that will prevent him from doing good work. He may believe that he is not capable of accomplishing something even though there is no reason for it. A child may think he is stupid because he does not understand how to make use of the most of his mental abilities, or he may accept another person’s mistaken estimate of his ability. People advanced in years may be handicapped by the mistaken belief that they are incapable of learning anything new because of their age.

He won’t go at a job (尽全力工作) with the confidence necessary for success, and he won’t work hard, even though he may think he is doing so. He is, therefore, likely to fail, and the failure will strengthen his belief in his incompetence.

[单项选择]Microsoft is no longer the world’s biggest company by market capitalization. Three other U.S. companies have overtaken the software giant in terms of stock market value. The firm’s value has gone down sharply by 41% so far this year, from nearly $600 billion to $358 billion.
Much of the reason for the fall has been the uncertainty prompted by the on-going anti-trust case.

Over the past year Microsoft shares have moved downwards from a high of $120 to $68 in early trading on 7 June. Meanwhile rival Cisco has seen its share price rise by $25 to more than $60 as the company has gained its role in providing the hardware for the Internet. And for most of the year it has been competing with computer chip maker Intel for the second place. Intel’s Pentium chips are widely used in personal computers worldwide.
The company that now holds the title of the wor
A. fierce competition from rivals
B. its involvement in a lawsuit
C. the court rulings
D. the decrease in sales volume
