Failure in Exams
As we all know, Senior Three students will experience various exams and it is hard to avoid failure sometimes, which greatly upsets them. Recently,
Breakfast has long been regarded as the most important meal of the day, vital for getting the body going and preventing overeating later on. 1.C to popular belief, the study found the first meal of the day had little impact 2. snacking or portion sizes later in the day.
The researcher added:“The 3. (信念) that breakfast is the ‘most important meal of the day’ is so widespread 4. many people are surprised to learn that there is a lack of scientific evidence5.
(表明）whether or how breakfast may directly cause changes in our health.6. is certainly true that people who regularly eat breakfast tend to be slimmer and healthier but these 7. (个人）also typically follow most other recommendations for a healthy lifestyle, so have more 8. b diets and take more physical exercise.”
In another study9.p this month, researchers at Birmingham 10.d volunteers into three groups. One skipped breakfast, others always ate it and a third continued with current diet. Four months later, no one in any group lost much weight.
If you are sending a text message, watching TV or listening to the radio, you may stop and give this your full attention. Multi-tasking shrinks(使……萎缩) the brain, research suggests.
A study found that men and women who frequently used several types of technology at the same time had less grey matter in a key part of the brain. University of Sussex researchers said, “Using mobile phones, laptops and other media devices simultaneously could be changing the structure of our brains.”
Worryingly, the part of the brain that shrinks is involved in processing emotion. The finding follows research which has linked multi-tasking with a shortened attention span, depression, anxiety and lower grades at school.
The researchers began by asking 75 healthy men and women how often they divided their attention between different types of technology. This could mean sending a text message while listening to music and checking email, or speaking on the phone while watching TV and surfing the internet. The volunteers were then given brain scans which showed they had less grey matter in a region called the anterior cingulated cortex (ACC) (前扣带皮质). Scientists have proved that brain structure can be changed on exposure to fresh environments and experience.
Other studies have shown that training – such as learning to play magic tricks or taxi drivers’ learning the map of London – can increase grey-matter densities(密度) in certain parts.
Experts have also warned of the harmful impact technology can have on our memory and attention span. The University of California team conducted a survey of more than 18,000 people aged between 18 and 99, and found 20% had problems with memory. Researchers were shocked greatly by the 14% of 18 to 39-year-old people who also worried about their memories.
Multi-tasking may shorten attention span, making it harder to focus and form memories, the researchers said, adding that youngsters may be particularly affected by stress.
