[简答题]Nowadays nearly everyone has suffered from a bad attack of forgetfulness when a password is needed.
The company computer. The home computer. Banking and ATM machines. Websites. Car and home security systems. The list goes on. It does not take long to accumulate a dozen or more passwords.
Scribbling them down on slips of paper or simply using the same password for anything and everything is how most people cope with the overload. The negative aspect of this is that either way makes it easier for hackers to invade computer privacy.
Researchers are now trying to do something about this by moving forward what may be an answer to the password puzzle—pictures.
Many companies are looking into various ways that images can be used to replace the standard, easily-forgotten string of letters and numbers. Pictures are much easier to remember. Researchers are also working on picture passwords that will make it more difficult for the average hacker.

Passage Five
Australia is nearly as large as the United States, but most of it is too dry for people to live in. Around this dry part are large sheep and cow farms. A few of them are as large as the smallest states in America. Often the nearest neighbours are several hundred kilometers away.
The two-way radio is very important to people who live on these great Australian farms. It works much like a telephone. A person can listen to someone else talk and then give an answer. For example, people on the large farms could talk to a doctor far away. They could tell the doctor about some- one who was ill, and the doctor could let them know how to look after the sick person.
As the large farms were so far from towns, the children could not go to school. Radio schools were started for them in some places. At a certain time each day, boys and girls turn on their radios and listen to teachers in cities far away.
Families on the large farms wanted to g
A. always went to school together

[多项选择]It took nearly eight years for the new heart drug BiDil to win approval from the Food and Drug Administration—and it won that approval only after its maker, a small company called NitroMed, repositioned it as a treatment earmarked for African Americans. But if NitroMed thought getting BiDil past the FDA was hard, wait until it tries marketing the drug to its target group. Even during its clinical trials, BiDil ran into resistance. Says Dr. Theodore Addai of Nashville’s Meharry Medical College, who had to enlist black patients for a 2001 trial: "We had to try to persuade them that this was not another Tuskegee. "
He’s referring to the infamous Tuskegee experiment, conducted by the U. S. government from the 1930s to the early ’70s, during which doctors denied nearly 400 black men in Alabama treatment for syphilis in order to observe the disease’s long-term effects. The scars left by Tuskegee are slow to heal in the African-American community, and many blacks remain deeply suspicious
[简答题]Nearly every day, giant tankers carry 8 million barrels of oil from Saudi Arabia (沙特阿拉伯) to refineries (炼油厂) around the world. But after the recent bombing in Riyadh, energy analysts (分析家) are nervously reassessing(重新评估) the stability of supplies of crude from the oil kingdom.
Since oil prices are relatively high entering winter, Americans will notice any further problems in Saudi Arabia as they fill up their gas tank or pay for home heating oil. 76) The price for West Texas crude closed above $32 a barrel last week, the highest point since the beginning of October and up from about $25 a barrel last year at this time.The higher price of crude is already reflected in steeper costs than last season: home heating oil is up some 19 cents a gallon, and gasoline is 9 cents a gallon higher. “The only thing keeping prices above $25 a barrel is fear of terrorist (恐怖分子) activity,” says Dennis Gartman, publisher of the Gartman Letter, an influential political and economic newsletter. “77) All t
