About E-learning

Although measured air pollution ranged below current WHO guidelines, a considerable proportion of the adults surveyed rated themselves as annoyed by car fumes (39.7%) or visible dust/soot: exposure (26.9%). Of the mothers (children’s study), 12.2% reported car fumes perceptible most of the time in the exposed area, 5.3% in the unexposed area.In the adult study, a series of factors were significantly associated with the perception of car fumes or dust/soot.

  At the yearly Rottnest Channel Swim in Western Australia, participants often smear their bodies with animal fat for insulation(36) the 70-degree water. But their own body fat also helps to keep them warm, like an extra layer of clothing (37) the skin. When scientists studied aspects of the event in 2006, they found that swimmers (38) a greater body mass index (BMI) appear to be at much (39)risk of getting hypothermia. Under certain conditions, though, overweight people might feel (40) than people of average weight. That’s because the brain combines two signals—the temperature (41) the body and the temperature on the surface of the skin—to determine when it’s time to constrict blood vessels (which (42) heat loss through the skin) and trigger shivering (which (43) heat). And since subcutaneous fat traps heat, an obese person’s core will tend to remain warm (44) his or her skin cools down. According to Catherine O’Brien, a research physiologist with the U.S. Army Research Institute of Environmental Medicine, it’s possible that the lower skin temperature would give (45) people the sense of being colder overall.

It wasn’t until the mid 20th century that doctors realised asthma attacks were caused by the swelling and contraction of the airways, Consequently, in the last 40 years there have been many developments in the treatment of asthma. There are presently two main types of medicine: preventers and relievers. A preventer is used every day and reduces the swelling of the airways, cutting the risk of on attack. A reliever, such as Ventolin, is taken when breathing has become difficult: this actually relaxes the muscles of the airways, reducing constriction and improving the airflow. The medicine is usually taken using a device for medical purpose. Prevention is also good treatment so if you have asthma, remember to keep generally healthy, take regular exercise and lots of vitamin C to avoid colds and flu—which can be dangerous for asthma sufferers. A healthy diet is also important, and do watch what you eat, as certain foods or food with certain substances to change the flavor can start asthma. By taking the right medication and making the right lifestyle choices, there is no reason why most asthma sufferers shouldn’t be able to lead perfectly healthy and active lives.

What can be inferred from the passage when people have to receive painful treatments?

The phrase “in time” in line 4, para. 7, is closest in meaning to______.

Which of the following is NOT true about the study made by Story and his colleagues?

According to the passage, what is the attitude of Stephen Smale toward PNI?

(B)

   “The only thing we have to fear is fear itself,”said Franklin D. Roosevelt. He might have been onto something: research suggests that people are happy to endure a bit more pain, if it means they spend less time waiting for it.

   Classical thanes of decision-making suppose that people bring rewards forward and postpone punishments, because we give far-off events less weight. This is called “temporal discounting”. But this theory seems to go out the window when it comes to pain.

  One explanation for this is that the anticipation of pain is itself unpleasant, a phenomenon that researchers have appropriately termed “dread”.

  To investigate how dread varies with time, Giles Story at University College London, and his colleagues, hooked up 33 volunteers to a device that gave them mild electric shocks. The researchers also presented people with a series of choices between more or less mildly painful shocks, sooner or later.

   During every “episode” there was a minimum of two shocks, which could rise to a maximum of 14, but before they were given them, people had to make a choice such as nine extra shocks now or six extra shocks five episodes from now. The number of shocks they received each time was determined by these past choices.

   No pain, no gain.

What can be said about temporal discounting?

According to the passage, which of the following statements about PNI is NOT true?

What can be inferred from the passage about Dole’s studies?

Why did Cole have an unusual hobby when he was on a post doctoral program?

(A)

  When Steve Cole was a postdoc, he had an unusual hobby: matching art buyers with artists that they might like. The task made looking at art, something he had always loved, even more enjoyable. “There was an extra layer of purpose. I loved the ability to help artists I thought were great to find an appreciative audience,” he says.
