Doctors have known for a long time that extremely loud noises can cause hearing damage or loss.The noise can be the sound of a jet airplane or machines in factories of loud music or other common sound at home and at work. A person only needs to hear the noise for little mire than one second to be affected.
An American scientist has found that using aspirin (阿斯匹林) increase the temporary (暂时的)hearing loss or damage from loud noise. He did an experiment using a number of students at a university who all had normal hearing. He gave them different amounts of aspirin for different periods of time, then he tested their hearing ability. He found that students who were given four grams of aspirin a day for two days suffered much greater temporary hearing loss than those who did not use aspirin. The hearing loss was about two times as great.
The scientist said millions of persons in the U.S. use much larger amounts of aspirin than were used in his experiment. He said these persons face a serious danger of suffering hearing loss from loud noise.

We’ve known that sitting for long periods of time every day has countless health consequences, like a higher risk of heart disease. But now a new study has found that sitting is also bad for your brain.
A study published last week, conducted by Dr. Prabha Siddarth at the University of California, showed that sedentary(久坐的)behavior is associated with reduced thickness of the medial temporal lobe(中颞叶), a brain area that is critical to learning and memory.
The researchers asked a group of 35 healthy people, ages 45 to 70, about their activity levels and the average number of hours each day spent sitting and then scanned their brains. They found that the subjects who reported sitting for longer periods had the thinnest medial temporal lobes. It means that the more time you spend in a chair the worse it is for your brain health, resulting in possible damage to learning and memory.
What is also interesting is that this study did not find a significant association between the level of physical activity and thickness of this brain area, suggesting that exercise, even severe exercise, may not be enough to protect you from the harmful effects of sitting.
It then surprisingly turned out that you don’t even have to move much to enhance cognition(认知); just standing will do the trick. For example, two groups of subjects were asked to complete a test while either sitting or standing. Participants are presented with conflicting stimuli(刺激), like the word “green” in blue ink, and asked to name the color. Subjects thinking on their feet beat those who sat by a 3-milicond margin.
The cognitive effects of severe physical exercise are well known. But the possibility that standing more and sitting less improves brain health could lower the bar for everyone.
I know, this all runs counter to received ideas about deep thought, from our grade school teachers, who told us to sit down and focus, to Rodin’s famous “Thinker,” seated with chin on hand.
They were wrong. You can now all stand up.
1.What can we infer from Paragraphs 3 and 4?
A.Severe exercise can lessen the damage of sitting.
B.Severe exercise can greatly improve our brain health.
C.Sedentary behavior will possibly damage our brain.
D.Brain health has nothing to do with sedentary behavior.
2.What does the underlined word “margin” in Paragraph 5 mean?
A.blank. B.edge.
C.decrease. D.difference.
3.What is the received idea about deep thought?
A.Sitting more is good for our mental health.
B.Sitting is better when we think.
C.Exercise more can improve our cognition.
D.We should stand while thinking.
4.The passage mainly tells us ________.
A.people tend to sit while thinking
B.standing more can make our brain healthier
C.physical exercise can improve our brain health
D.sedentary behavior leads to countless health problems

The fact that ants are fascinating insects has been known for some time. Now, scientists have discovered a large number of wood ants living in an abandoned underground storehouse in Templewo, Poland, despite having no obvious source of food.
Polish zoologist Wojciech Czechowski and his team began studying the underground colony in 2013. They found the ants built a 60-cm high nest in the soil directly over the storehouse vertical air pipe. As years passed, the metal covering on the pipe eroded, leaving behind a hole that thousands of worker ants accidentally slip into each day as they go about their daily chores. The scientists say that there are no sources of food in the storehouse. This means that the insects live in a state of near starvation.
In July 2015, the researchers disturbed part of the ant nest in search of larvae (幼虫), cocoons(茧), and queens. They found nothing, leading them to suspect that the lack of food and cold temperatures made reproduction impossible and that the group tending the nest is entirely made up of non-reproductive female workers. Their population is refilled every year, by a new rain of unfortunate ants that slide down the hole. The researchers say that when they returned in January 2016, the nest had been repaired. It appears that despite the terrible conditions, the worker ants do not stop constructing their nest.
Wood ants are known for their ability to adapt to bad living conditions. In this case, the millions of worker ants trapped in the storehouse have no choice. But instead of losing hope, they are making the best of the situation—a classic example of “when life gives you lesions make lemonade.”
1.How did the wood ants arrive in the storehouse?
A. They fell down there by accident.
B. The research team brought them there.
C. The storehouse builders left them there.
D. They were attracted by the environment.
2.What does the underlined word “eroded” in Paragraph 2 probably mean?
A. Expanded. B. Rotted. C. Exploded. D. Melted.
3.What did the researchers find in the nest?
A. Larvae. B. Cocoons. C. A queen. D. Worker ants.
4.Why did the population of wood ants remain steady?
A. They had enough food.
B. They were able to reproduce.
C. They adapted to the conditions.
D. They had new comers to join them.
