3 . The rapid increase of the oil price has brought the world to its senses. Scientists are seeking suitable alternative (替换) but so far in vain. They are considering how they can make better use of the two other major fuels, coal and natural gas, but they have found that neither can replace oil in their economics. In recent years, there has been a growing concern for the environment and coal is not a popular fuel with environmentalists. Natural gas, the purest of the three fuels, is also the most limited in supply.

The answer would seem to lie in nuclear power stations. They need very little fuel to produce enormous amounts of power and they do not pollute the atmosphere. Their dangers, however, are so great and the costs of building them are also high. Not only could one accident in a nuclear power station spread as much radioactivity (放射物) as a thousand Hiroshima atom bombs, but the radioactive waste from these stations is extremely dangerous.

Scientists have recently turned their attention to natural sources of energy: the sun, the sea, the wind and hot spring, of which the sun seems the most promising source for the future. Houses have already been built which are heated entirely by solar energy. However, solar energy can only be collected during daylight hours, and in countries where the weather is unreliable, an alternative heating system has to be included.

However, many scientists are optimistic that new ways of generating large amounts of energy will be successfully developed, but at the same time they fear the consequences. If the world population goes on increasing at its present rate, we may, in fifty years’ time, be burning up so much energy that we would damage the earth’s atmosphere. By raising the temperature of the atmosphere,we could melt the Arctic and Antarctic ice-caps and change the pattern of vegetable and animal life throughout the world——a frightening possibility.

5 . Social media has completely taken over everyday life, affecting how society runs and changing individuals in ways that even they can feel. While social media can act as a platform for people to express themselves, it can also be overwhelming, especially for high school teens.

To teenager Bryson Lan, quitting social media helped eliminate (消除) a significant distraction in his routine and keep up with teachers. “I was scrolling through social networking sites so much,” Lan said. “I was also starting to struggle since I entered my high school year. When school started, I was super overwhelmed (不知所措的), and I was just not ready for it.”

Most teenagers fear that by eliminating these apps, they will miss out on connections with their peers and feel a significant loss to their social life. However, Lan found he didn’t miss anything during his time without social media.

Another problem with social media is the amount of “junk content” posted. People are regularly posting and updating on social media, and much of the content has no meaning to other viewers and is ultimately a time suck.

However, social media isn’t all negative. Social media can be a place to develop passions and boost creativity. For example, Lan found his interest in photography blossom after seeing works from other photographers on social media. “Social media is a good place where you can have a portfolio (作品集) or upload your works,” Lan said. “A lot of people have photography accounts or art accounts. In some ways, I think it actually furthers your hobby.” “Thanks to this revolutionary development of social media, we can enjoy a world where everyone is closer than before,” Lan said. “But we also need to have the skills to make good use of social media, and that depends on each person’s efforts.”

1. What did getting rid of social media bring Lan?

A．More distractions.	B．Confusion about life.
C．A smaller social circle.	D．More attention on his studies.

C．Innovative development of social media.	D．The problems social media brings people.

6 . Inconvenient Truths

If doctors lie, it is surely inexcusable. One of the basic_________ the public have of doctors is honesty. But what would you think if I told you that research has shown that 70 per cent of doctors   _________ to lying to their patients? If I am honest, I have told lies to my patients.

Mrs Walton was in her eighties and _________ to see her husband. She would try to get up to find him, despite being at risk of falling. “He’s on his way, don’t worry,” the nurses would say this to calm her down. I said the same thing to her. But it was a lie. He died two years ago. The truth, if I can use that word, is that it is a _________ to lie sometimes.

Mrs Walton is one of the dementia (痴呆) sufferers, who lose their short-term memory and the memory of_________ events, but hold memories from the distant past. Sufferers are trapped forever in a confusing past that many realize bears little   _________ to the present, but are at a loss to explain. Those with dementia often feel upset, scared and confused that they are in a strange place, _________ by strange people, even when they are in their own homes with their family, because they have gone back to decades ago.

They look at their adult children   _________ and wonder who they could be because they think their children are still little kids. I have had countless families break down in tears, not knowing how to react as their loved one moves further away from them back into their distant past and they are   _________ in the present. And how, as the doctor or nurse caring for these patients, does one manage the anger and outbursts of distress that comes with having no   __________ of your life for the past ten or 20 years? The lies that doctors, nurses and families tell these patients are not big, elaborate lies — they are   __________ comforts intended to calm and allow the subject to be swiftly changed.

__________ with them about this false reality is not heartless or unprofessional — it is actually kind. That’s not to say that lying to patients with dementia__________ is right or defensible. But what kind-hearted person would put another human being through the unimaginable pain of learning, ________ again and again, that they have lost their beloved ones. It would be an unthinkable cruelness.

Sometimes honesty is __________ not the best policy.

9 . In the days before the Internet, critical thinking was the most important skill of informed citizens. But in the digital age, according to Anastasia Kozyreva, a psychologist at the Max Planck Institute of Human Development, and her colleagues, an even more important skill is critical ignoring.

As the researchers point out, we live in an attention economy where content producers on the Internet compete for our attention. They attract us with a lot of emotional and eye-catching stories while providing little useful information, so they can expose us to profit-generating advertisements. Therefore,we are no longer customers but products, and each link we click is a sale of our time and attention. Toprotect ourselves from this, Kozyreva advocates for learning the skill of critical ignoring, in which readers intentionally control their information environment to reduce exposure to false and low-quality information.

According to Kozyreva, critical ignoring comprises three strategies. The first is to design ourenvironments, which involves the removal of low-quality yet hard-to-resist information from around. Successful dieters need to keep unhealthy food out of their homes. Likewise, we need to set up a digital environment where attention-grabbing items are kept out of sight. As with dieting, if one tries to bank onwillpower not to click eye-catching “news”, he’ll surely fail. So, it’s better to just keep them out of sightto begin with.

The next is to evaluate the reliability of information, whose purpose is to protect you from false and misleading information. It can be realized by checking the source in the mainstream news agencies which have their reputations for being trustworthy.

The last goes by the phrase “do not feed the trolls.” Trolls are actors who internationally spread false and hurtful information online to cause harm. It may be appealing to respond to them to set the facts straight, but trolls just care about annoying others rather than facts. So, it’s best not to reward their bad behaviour with our attention.

By sharpening our critical ignoring skills in these ways, we can make the most of the Internet while avoiding falling victim to those who try to control our attention, time, and minds.

1. What can we learn about the attention economy from paragraph 2?

A．It offers little information.	B．It features depressing stories.
C．It saves time for Internet users.	D．It seeks profits from each click.

2. Why does the author mention dieters in paragraph 3?

A．To discuss the quality of information

B．To prove the benefits of healthy food.

C．To show the importance of environments.

D．To explain the effectiveness of willpower.

3. What should we do to handle Internet trolls according to the text?

A．Reveal their intention.	B．Turn a deaf ear to them.
C．Correct their behaviour.	D．Send hard facts to them.

4. What is the text mainly about?

A．Reasons for critical thinking in the attention economy.

B．Practising the skill of critical ignoring in the digital age.

C．Maximizing the benefits of critical ignoring on the Internet.

D．Strategies of abandoning critical thinking for Internet users

10 . Housing officials say that lately they are noticing something different: students seem to lack the will, and the skill, to deal with ordinary conflicts. “We have students who are mad at each other and they text each other in the same room,” says a teacher. “So many of our conflicts are because kids don’t know how to solve a problem by formal discussion.”

And as any pop psychologist will tell you, bottled emotions lead to silent discontent (不满) that can boil over into frustration and anger. At the University of Florida, emotional conflicts occur about once a week, the university’s director of housing education says, “Over the past five years, roommate conflicts have increased. The students don’t have the person-to-person discussions and they don’t know how to handle them.” The problem is most dramatic among freshmen; housing professionals say they see improvement as students move toward graduation, but some never seem to improve, and they worry about how such students will deal with conflicts after college.

Administrators guess that reliance on cell phones and the Internet may have made it easier for young people to avoid uncomfortable encounters. Why express anger in person when you can vent (发泄) in a text? “Things are posted on someone’s wall on Facebook like: Oh, my roommate kept me up all night studying,” says Dana Pysz, an assistant director at the University of California, Los Angeles. “It’s a different way to express their conflict to each other, consequently creating even more conflicts as complaints go public.” In recent focus groups at North Carolina State University, dorm residents said they would not even deal with noisy neighbors on their floor.

Administrators point to parents who have fixed their children’s problems in their entire lives. Now in college, the children lack the skills to attend to even modest conflicts. Some parents continue to interfere (干涉) on campus.

1. What is the main reason for many roommate conflicts?

A．Students are not good at reaching an agreement about the problems.

B．Students are not satisfied with each other.

C．Housing directors are not responsible for them.

D．Students are not strong-willed.

2. What do we learn from the second paragraph?

A．Students, especially freshmen, should bottle up their dissatisfaction.

B．Students in Florida sit down and have a person-to-person talk once a week.

C．Not all students are able to handle conflicts by the time they graduate.

D．The number of conflicts among roommates has decreased in the past five years.

3. What is the attitude of Dana Pysz when he mentions roommates reveal their conflicts in the media?

A．Disapproving.

B．Indifferent.

C．Supportive.

D．Unclear.

4. What should parents do according to the passage?

A．They should be involved in their children’s life on campus.

B．They should deal with their children’s problems in their whole lives.

C．They should constantly contact the administrators of the college.

D．They should teach their children the skills to tackle the conflicts.
