【题目】—What do you think of store shopping in the future?

—Personally, I think it will exist along with home shopping but ______.

A. will never replace B. would never replace

C. will never be replaced D. would never be replaced

【答案】C

【解析】

试题解析：考查时态与语态。首先考虑时态，空白处之前为but，表示转折，但前后时态应保持一致，故仍使用will；其次考虑语态，分析replace的主语为it，代指前文中store shopping，与代替之间的关系为被动关系。故应为will never be replaced。句意：你怎么看待将来的商店购物。个人观点，我认为它会和家中购物一样长久存在，但永远不会被取代。故选C。

【题目】More and more people are taking their iPads to bed with them to surf the web, check facebook or send e-mails before switching off the light. But researchers are warning that the blue light their screens give off can stop users getting a good night’s sleep. That is because this type of light is similar to daylight, convincing the brain that it is still daytime. Blue light prevents the production of a brain chemical called melatonin, which helps us fall asleep. By contrast, light which is more orange or red does not prevent melatonin production, perhaps because our brains recognize it as a cue that the day ends.

Scientists have known for years that staring at screens late in the evening can affect sleep ---- they are television screens, computer screens or mobile phone screens. However, because mobiles and iPads are by nature portable ---- not to say addictive ---- more people are taking them into the bedroom. Users also tend to hold them much closer to their eyes than a computer or television screen.

Researchers are warning that looking at iPad displays for more than two hours leads to lower natural melatonin levels as the devices give off blue light. They say, “Turning off the devices at night is the final solution. But if you have to use these devices at night, dim the display to cut down irritation of the eyes and limit the time you spend on them before bed.”

They wrote in the journal Applied Ergonomics(应用人类工程学) that iPad makers should adjust the spectral power distribution(光谱功率分布) of the devices so that they affect the sleep patterns of users less.

It is not just a good night’s sleep that could be harmed by too much late night screen time. Researchers know that long-term harm to sleep patterns can lead to an increased risk of obesity and even cancers.

【1】Blue light prevents iPad users from sleeping well because ____.

A. it is the same as daylight which keeps people awake

B. it makes the brain more active

C. it is brighter than light that is more orange or red

D. it can help decrease the production of melatonin

【2】The underlined phrase “dim the display” means ____.

A. keep away from the display

B. make the display less bright

C. clean the display carefully

D. turn off the display

【3】 In the last paragraph, the author intends to ____.

A. warn of the seriousness of long-term poor sleep

B. call on researchers to study sleep patterns

C. show the danger of obesity and cancers

D. show how sleep is harmed by using iPads too much

【4】What’s the main idea of the passage?

A. Scientists are warning that blue light is bad for our health.

B. People should limit the use of electronic devices

C. Using iPads before bed can cause a poor night’s sleep.

D. Looking at screens of iPads increase chances of sleeplessness.

Of all the components of a good night’s sleep, dreams seem to be last within our control. In dreams, a window opens into a world where there is zero logic and dead people can speak. A century ago, Freud formulated(创立理论) his revolutionary theory that dreams were the hidden shadows of our unconscious desires and fears; by the late 1970s, neurologists(神经病学家) had switched to thinking of them as just “mental noise”—the random byproducts(副产品) of the neural repair work that goes on during sleep. Now researchers suspect that dreams are regulating moods while the brain is “offline”. And one leading authority says that these intensely powerful mental events actually can be bought under conscious control, to help us sleep and feel better. “It’s your dream,” says Rosalind Cartwright, chair of psychology at Chicago’s Medical Center. “If you don’t like it, change it.”

Evidence from brain imaging supports this view. The brain is as active during rapid eye movement sleep when most vivid dreams occur as it is when fully awake, says Dr. Eric Nofzinger at the University of Pittsburgh. But not all parts of the brain are equally involved: the limbic system or the emotional brain is especially active, while the prefrontal cortex—the center of intellect and reasoning, is relatively quiet. “We wake up from dreams happy or depressed, and those feelings can stay with us all day,” says Stanford sleep researcher Dr. William Dement. This link is shown among the patients in Cartwright’s clinic. Most people seem to have more bad dreams early in the night, progressing toward happier ones before awakening, suggesting that they are working through negative feelings generated during the day. Because our conscious mind is occupied with daily life we don’t always think about the emotional significance of the day’s events—until, it appears, we begin to dream.

There is probably little reason to pay attention to our dreams at all unless they keep us from sleeping or “We wake up in a panic,” Cartwright says. Those suffering from persistent nightmares should seek help from a therapist. For the rest of us, the brain has its ways of working through bad feelings. Sleep or rather dream on it and you’ll feel better in the morning.

A. Dreamers can exercise conscious control over them.

B. They are shadows of our unconscious desires and fears.

C. People with more emotional changes dream more often.

D. They are actually products of our brain’s neural repairs.

A. The functions of vivid dreams.
