Older people with hearing loss may suffer faster rates of mental decline. People who have hearing trouble suffered meaningful impairments in memory, attention and learning about three years earlier than people with normal hearing, a study published online January 21 in JAMA Internal Medicine reveals.

The finding supports the idea that hearing loss can have serious consequences for the brain，says Patricia Tun of Brandeis University in Waltham，Mass., who studies aging. “I'm hoping it will be a real wake-up call in terms of realizing the importance of hearing. ”

Compared with other senses, hearing is often overlooked, Tun says. “We are made to interact with language and to listen to each other, and it can have damaging effects if we don't.”

Frank Lin of Johns Hopkins School of Medicine and colleagues tested the hearing of 1,984 older adults. Most of the participants, who averaged 77 years old, showed some hearing loss — 1,162 volunteers had trouble hearing noises of less than 25 decibels, comparable to a whisper or rustling leaves. The volunteers; deficits reflect the hearing loss in the general population: Over half of people older than 70 have trouble hearing.

Over the next six years, these participants underwent mental evaluations that measured factors such as short-term memory, attention and the ability to quickly match numbers to symbols. Everybody got worse at the tasks as time wore on, but people with hearing loss had an especially sharp decline, the team found. On average, a substantial drop in performance would come about three years earlier to people with hearing loss.

Lin cautions that the study has found an association between hearing loss and mental abilities; the researchers can't conclude that hearing loss directly causes the decline. Yet more and more studies are turning up ways that diminished hearing could damage the brain.

A person who can't hear well might avoid social situations, and isolation(孤立)is known to be bad for the brain. “You gradually become more socially withdrawn, ” Lin says. “Social isolation is a major, major factor for dementia(痴呆)and cognitive decline. ”

Other studies suggest that when people struggle to interpret and decode(译解）words, their brains divert energy away from other tasks, such as memory. Audiologist and psychologist Kathy Pichora — Fuller says that this brain drain happens to everyone, even people without hearing loss. Studies have shown that people are worse at remembering things when they're in a noisy room, for instance. People with hearing loss may be constantly diverting a large swath(—大片)of their brainpower，leaving less for other mental tasks, says Pichora— Fuller, of the University of Toronto Mississauga.

1. Mass does the research to _____ .

A. present the mental decline

B. attach importance to hearing

C. compare hearing with other senses

D. exaggerate the damaging effects

2.What is paragraph 4 mainly about?

A. The outcome of the test.

B. The design of the test

C. The participants of the test.

D. The purpose of the test.

3.Dementia and cognitive decline mainly result from ____ .

A. social isolation B. hearing loss

C. memory loss 　　　 D. speech impairment

4.The underlined word “divert” probably means _____ .

Those who have suffered from insomnia know the sinking feeling of watching the clock tick．Now a new study in the Archives of Internal Medicine suggests that lying in bed awake may actually contribute to the problem of sleeplessness．

The study of 79 adults（average age 72）with insomnia aimed to determine whether brief behavioral interventions for insomnia would help．Traditional behavioral therapy（疗法）requires at least half a dozen hour-long sessions with a therapist — a costly commitment many patients either can't make or don't have access to．Other options include sleep-aiding medications or supplements．In the current study，the 39 participants in the behavioral therapy group received a 45- to 60-minute instructing session，plus a 30-minute follow-up session and two 20-minute phone calls．

Doctors offered the following behavioral interventions for improving sleep: reduce time in bed; get up at the same time every day，regardless of sleep duration; don't go to bed unless sleepy; and don't stay in bed unless asleep．

The other 40 participants in the study were given printed educational materials about insomnia，which included the same instructions given to the intervention group，but without the individualized sessions with a therapist．Two weeks later，the latter group also got a 10-minute follow-up phone call．

At the end of four weeks，the behavioral treatment group was significantly more likely to show improvements in sleep than the printed-materials group．By that time，55% of those who received behavioral treatment no longer met the criteria for insomnia，compared with 13% of the group that got educational brochures．

The good news comes at the same time as a report on the health effects of insomnia from the U．K．'s Mental Health Foundation．The report，Sleep Matters，suggests a link between insomnia and poor relationships，low energy levels and an inability to concentrate．Poor sleep has already been linked to depression，immune deficiency and heart disease．

1.What is the meaning of the underlined word “ insomnia”?

A．sleeplessness　　　 　　 B．depression

C．heart disease　　 　　　 D．immune deficiency

2.What is the disadvantage of traditional behavioral therapy?

A．It can’t help．

B．It costs a lot of money．

C．It requires sessions with a therapist．

D．It includes sleep-aiding medications．

3.How to improve sleep according to the doctor?

A．Lying in bed awake．

B．Get up early every day．

C．Don’t go to bed late at night．

D．Don’t stay in bed if you are not asleep．

4.We can learn from the text that insomnia may cause the following results except________．

A．depression　　　 　　　 B．concentration

C．immune deficiency 　 D．heart disease
