---_______ one and a half months enough for the project to be finished?

  ---I am afraid not. The professor is ill and only after he recovers ________ go on with it.

A. Is; he can              B. Are; he can                  C. Is; can he                    D. Are; can he

 

【答案】

C

【解析】

試題分析：句意：這個(gè)項(xiàng)目完成一個(gè)半月足夠了嗎？--恐怕不能。教授生病了，只有他恢復(fù)了才能繼續(xù)。第一空需要be動(dòng)詞，主語(yǔ)是one and a half months表示一段時(shí)間，謂語(yǔ)用單數(shù)，所以排除BD，第二句話(huà)是only+時(shí)間狀語(yǔ)從句在句首，后面用部分倒裝，can放在主語(yǔ)前面，所以選C。

考點(diǎn)：考查主謂一致和倒裝句

　　E-mail systems at thousands of companies and government offices around the world were attacked by a virus(病毒)called “Melissa” that disguises(偽裝)itself as an “important message” from a friend．In spite of a weekend of warnings, more than 50 000 computers at about 100 places around the world have been attacked by the virus, computer security experts said on Monday．

　　The virus began to show up last Friday and spread rapidly on Monday by making computers fire off dozens of infected(被傳染的)e-mails．Although the virus causes no serious damage to a computer, its effect was far reaching．

　　To make matters worse, a similar virus called“Papa”was discovered on Monday．Papa is programmed to send out even more infected e-mails than Melissa．

　　The Melissa virus comes in the form of an e-mail, usually containing the subject line “Important Message”．It appears to be from a friend．The body of the e-mail message says, “Here is that document you asked for．．．don’t show it to anyone else．”Attached(附)to the message is a document file．

　　Once the user opens that file, the virus digs into the user’s address book and sends infected documents to the first 50 addresses．E-mails from the Papa virus include an attached spreadsheet(電子數(shù)據(jù)文件)file．When the user opens that file, the virus sends 60 infected e-mails．

　　The reason why this is spreading so fast is that you are getting it from people you know．You should never open documents or attachments from people you don’t know．People who get an unexpected e-mail with the “important message” subject line should delete it immediately and not open the message．

(1)

The concept of personal choice in relation to health behaviors is an important one. An estimated 90 percent of all illnesses may be preventable if individuals would make sound personal health choice and do not like to see it restricted when it is within the legal and moral boundaries of society. The structure of American society allows us to make almost all our own personal decisions that may concern our health. If we so desire, we can smoke, drink excessively, refuse to wear seat belts, eat whatever foods we want, and live a completely sedentary life style without any exercise. The freedom to make such personal decisions is a fundamental aspect of our society, although the wisdom of these decisions can be questioned. Personal choices relative to health often cause a difficulty. As one example, a teenager may know the facts relative to smoking cigarettes and health but may be pressured by friends into believing it is the socially accepted thing to do.?

A multitude of factors, both inherited and environmental, influence the development of health related behaviors, and it is beyond the scope of this text to discuss all these factors as they may affect any given individual. However, the decision to adopt a particular health related behavior is usually one of personal choices. There are healthy choices and there are unhealthy choices. In discussing the morals of personal choice, Fries and Grapo drew a comparison. They suggest that to knowingly give oneself over to a behavior that has a statistical probability of shortening life is similar to attempting suicide. Thus, for those individuals who are interested in preserving both the quality and quantity of life, personal health choices should reflect those behaviors that are associated with a statistical probability of increased vitality and longevity.

68．The concept of personal choice concerning health is important because ____.

A．personal health choice helps cure most illness

B．it helps raise the level of our medical knowledge

C．it is essential to personal freedom in American society

D．wrong decisions could lead to poor health

69．To “l(fā)ive a completely sedentary life style”(L7,Para.1)in the passage means____.

A．to “l(fā)ive an inactive life”    B．to “l(fā)ive a decent life”

C．to “l(fā)ive a life with complete freedom”     D．to “l(fā)ive a life of vice”

70．Sound personal health choice is often difficult to make because ____. ?

A．current medical knowledge is still insufficient

B．there are many factors influencing our decisions

C．few people are willing to trade the quality of life for the quantity of life

D．people are usually influenced by the behavior of their friends
