【題目】We ____________ here on time. But the traffic was so heavy.

A. can have come B. must have come

C. should have come D. need have come

【答案】C

【解析】

試題分析: 句意：我們本該準(zhǔn)時(shí)到達(dá)這里的。但是，交通太擁堵了。情態(tài)動(dòng)詞+have done表示對(duì)過去事情進(jìn)行推測，can have done可能已經(jīng)做了某事；can’t have done不可能已經(jīng)做了某事；must have done一定已經(jīng)做了某事，否定推測用can’t；should have done本應(yīng)該做某事；shouldn’t have done本不應(yīng)該做某事；need have done本需要做某事。我們本應(yīng)該按時(shí)到達(dá)，實(shí)際上未能按時(shí)到，故選C。

【題目】How many times a day do you check your email? When you wake up? Before bed? A dozen times in between? The technology that was supposed to simplify our lives has become the vital time-suck: the average teen spends more than seven hours a day using technological devices, plus an additional hour just text-messaging friends.

The advantage of technological devices is connectedness: email lets us respond on the go, and we are in touch with more people during more hours of the day than at any other time in history. But is it possible we’re more lonely than ever, too? That’s what MIT professor Sherry Turkle observes in her new book, Alone Together, a fascinating portrait of our changing relationship with technology. Turkle details the ways technology has redefined our comprehension of closeness and loneliness—and warns us of the danger of accepting such virtual(虛擬的) relationships in place of lasting emotional connections.

For Turkle, the biggest worry is the effect all these shallow connections have on our development. Is technology offering us the lives we want to live? “We’re texting people at a distance,” says Turkle, “We’re using lifeless objects to convince ourselves that even when we’re alone, we feel together. And then when we’re with each other, we put ourselves in situations where we are alone—constantly on our mobile devices. It’s what I call a perfect storm of confusion about what’s important in our human connections.”

What can’t be denied is that technology, whatever its faults, makes life a whole lot easier. It allows us to communicate with more people in less time and makes conversation simple. But it can also be seductive(具有誘惑性的), providing more stimulation than our natural lives. There are usually some unhealthy videos online which remove teenagers’ attention from their schoolwork. Besides, some online activities make people addicted, which occupied their daily life and affected their ability to form real-world relationships.“Technology can be more immediately satisfying than the labor of building an intimate relationship,” said one highschool student, “Every time I text, I start to have some happy feelings.”

But are any of those feelings equal to the kind we feel when engaged in real, face-to-face communication? Online, you can neglect others’ feelings. In a text message, you can avoid eye contact. A number of studies have found that this generation of teens is less sympathetic than ever. That doesn’t spell disaster, says Turkle—but，

【1】From the first paragraph we can infer that_________.

A. email checking helps people wake up early

B. technological device production has been simplified

C. using technological devices costs teens much time

【2】Turkle’s new book mainly discussed________.

A. ways to draw a fascinating portrait

B. how technology influences human relationships

C. the dangers of accepting emotional connections

D. the advantages of technology

A. starting to accept emotional connections in place of virtual connections

B. convincing themselves by using fewer lifeless objects in connections

C. dropping the use of technological devices for connection with each other

【4】Which of the following is True according to the passage?

A. Others’ feelings can be ignored in online communication.

B. No stimulation is provided in natural life connections.

C. People always send text messages to avoid eye contact.

D. It may be a disaster that teens are less sympathetic than ever.

【題目】When something goes wrong, it can be very satisfying to say, “Well, it’s so-and-so’s fault.” or “I know I’m late, but it’s not my fault; the car broke down(拋錨).” It is probably not your fault, but once you form the habit of blaming somebody or something else for a bad situation, you are a loser. You have no power and could do nothing that helps change the situation. However, you can have great power over what happens to you if you stop focusing on whom to blame and start focusing on how to remedy the situation. This is the winner’s key to success.

Winners are great at overcoming problems. For example, if you were late because your car broke down, maybe you need to have your car examined more regularly. Or, you might start to carry along with you the useful phone numbers, so you could call for help when in need. For another example, if your colleague causes you problems on the job for lack of responsibility or ability, find ways of dealing with his irresponsibility（不負(fù)責(zé)任） or inability rather than simply blame the person. Ask to work with a different person, or don’t rely on this person. You should accept that the person is not reliable and find creative ways to work successfully regardless of（不管） how your colleague（同事）fails to do his job well.

This is what being a winner is all about—creatively using your skills and talents so that you are successful no matter what happens. Winners don’t have fewer problems in their lives; they have just as many difficult situations to face as anybody else. They are just better at seeing those problems as challenges and opportunities to develop their own talents. So, stop focusing on “whose fault it is.” Once you are confident about your power over bad situations, problems are just stepping stop on for success.
【1】According to the passage, winners __________.

A. deal with problems rather than blame others

A. avoid B. accept C. improve D. consider

【3】When your colleague brings about a problem, you should __________.

A. find a better way to handle the problem

B. blame him for his lack of responsibility

C. tell him to find the cause of the problem

D. ask a more able colleague for help

【4】When problems occur, winners take them as __________.

A. excuses for their failures

B. barriers to greater power

C. challenges to their colleagues

D. chances for self-development

【5】Which of the following is the best title for the passage?

A. A Winner’s Secret.
