单项选择题
In what now seems like the prehistoric times of computer history, the early postwar era, here was a quite widespread concern that computers would take over the world from man one day. Already today, less than forty years later, as computers are relieving us of more and more of the routine tasks in business and in our personal lives, we are faced with a less dramatic but also less foreseen problem. People tend to be over-trusting of computers and are reluctant to challenge their authority. Indeed, they behave as if they were hardly aware that wrong buttons may be pushed, or that a computer may simply malfunction.
Obviously, there would be no point in investing in a computer if you had to check all its answers, but people should also rely on their own internal computers and check the machine when they have the feeling that something has gone away. Questioning and routine double checks must continue to be as much a part of good business as they were in precomputer days. Maybe each computer should come with the following warming: for all the help this computer may provide, it should not be seen as a substitute for fundamental thinking and reasoning skills.
What is the main purpose of this passage?（　　
A.Tolookbacktotheearlydaysofcomputers
B.Toexplainwhattechnicalproblemsmayoccurwithcomputers
C.Todiscourageunnecessaryinvestmentincomputers
D.Towarnagainstamentallylazyattitudetowardscomputers

单项选择题
A house is the most expensive thing most people will ever buy. Very few people have enough money of their own to buy a home, so they have to borrow money from a bank. Borrowing money from a bank to buy a house is called “take a mortgage（抵押）”. The bank usually lends money or gives a mortgage for twenty-five years. Houses are so expensive that many people nowadays have to borrow as much as $50 000. In other words they will have a $50 000 mortgage.
How can you get a mortgage? When you find a house you like, you go to a bank. The bank will research you financial（金融的）history and decide if they think you are a good risk. They will want to know what kind of job you have, what kind of salary you make, and how long you have had the job. They will also want to know how much money you have. In addition, the banks will require a down payment. Depending on which state you live in, the bank may require as much as 30% of the price of the house as a down payment, The bank will then lend you the rest of the money to buy the house. Many people are never able to buy a house because they cannot save enough money for the down payment.
Which is not one of the things researched by a bank？（　　）
A.Howmuchmoneytheborrowerowns
B.Whatsalarytheborrowermakes
C.Whatkindofjobtheborrowerhas
D.Whatkindofhousetheborrowerlivesin
