After taking into account differences in other factors that could affect stroke risk, such as high blood pressure, the researchers estimated that subjects who consumed up to two alcoholic drinks daily were only half as likely to have suffered clot-type strokes as nondrinkers. Clot-type strokes account for 80% of all strokes, a leading cause of the US deaths and disability. Stroke risk increased with heavier drinking. At seven drinks per day, risk was almost triple that of moderate drinkers.

An expert spokesman for the American Heart Association, who was not involved in the study, said it was well-done and important information. But it shouldn’t be interpreted to mean, “I can have two drinks and therefore not worry about my high blood pressure or worry about my cholesterol,” said Dr. Edgar J. Kenton, an associate professor of clinical neurology （神经学） at Thomas Jefferson University Medical College in Philadelphia. Instead, he said, the study provides good reason to do further research and to add alcohol to the list of modifiable （可更改的） risk factors for stroke.

Passage Four

Communications technologies are far from equal when it comes to conveying the truth. The first study to compare honesty across a range of communications media has found that people are twice as likely to tell lies in phone conversations as they are in emails. The fact that emails are automatically recorded - and can come back to haunt （困扰） you - appears to be the key to the finding.

Jeff Hancock of Cornell University in Ithaca, New York, asked 30 students to keep a communications diary for a week. In it they noted the number of conversations or email exchanges they had lasting more than 10 minutes, and confessed to how many lies they told. Hancock then worked out the number of lies per conversation for each medium. He found that lies made up 14 per cent of emails, 21 per cent of instant messages, 27 per cent of face-to-face interactions and an astonishing 37 per cent of phone calls.

His results, to be presented at the conference on human-computer interaction in Vienna, Austria, in April, have surprised psychologists. Some expected emailers to be the biggest liars, reasoning that because deception （欺骗） makes people uncomfortable, the detachment （非直接接触）of emailing would make it easier to lie. Others expected people to lie more in face-to-face exchanges because we are most practiced at that form of communication.

But Hancock says it is also crucial whether a conversation is being recorded and could be reread, and whether it occurs in real time. People appear to be afraid to lie when they know the communication could later be used to hold them to account, he says. This is why fewer lies appear in email than on the phone.

People are also more likely to lie in real time — in an instant message or phone call，say — than if they have time to think of a response, says Hancock. He found many lies are spontaneous （脱口而出的） responses to an unexpected demand, such as: “Do you like my dress?”

Hancock hopes his research will help companies work out the best ways for their employees to communicate. For instance, the phone might be the best medium for sales where employees are encouraged to stretch the truth. But given his results, work assessment, where honesty is a priority, might be best done using email.

76. Hancock’s study focuses on ______. （      ）

A. the consequences of lying in various communications media

B. the success of communications technologies in conveying ideas

C. people’s preferences in selecting communications technologies

D. people’s honesty levels across a range of communications media

77. Hancock’s research finding surprised those who believed that ______. （      ）

A. people are less likely to lie in instant messages

B. people are unlikely to lie in face-to-face interactions

C. people are most likely to lie in email communication

D. people are twice as likely to lie in phone conversations

78. According to the passage, why are people more likely to tell the truth through certain media of communication? （      ）

A. They are afraid of leaving behind traces of their lies.

B. They believe that honesty is the best policy.

C. They tend to be relaxed when using those media.

D. They are most practiced at those forms of communication.

79. According to Hancock, the telephone is a preferable medium for promoting sales because______. （      ）

A. salesmen can talk directly to their customers

B. salesmen may feel less restrained to exaggerate

C. salesmen can impress customers as being trustworthy

D. salesmen may pass on instant messages effectively

80. It can be inferred from the passage that ______. （      ）

A. honesty should be encouraged in interpersonal communications

B. more employers will use emails to communicate with their employees
