A new computer treatment is being used to deal with obesity in children. Connected to a small dining set, consisting of (包括) scales and a plate, a mini computer teaches children how to eat and reminds them when to stop.
“In very fat people, hunger signals from the stomach to the brain stop functioning. But the new computer system teaches the children how to receive these messages again,” says Dr. Julian Hamilton-Shield, the Bristol University senior lecturer leading the treatment trials.(实验)。
The computer , called a Mandometer, records and stores the weight loss from the plate when children eat. As the food is leaving the plate , a curve( 曲线)is produced on the computer screen suggesting whether the child is eating too quickly.
“Children with weight problems often eat too quickly. We want them to eat steadily稳定地） and slowly and the system teaches them to slow down. It’s a bit like retraining, ” says Hamilton-Shield.
Obesity now represents (代表) one of the major threats to the future health of children. About one in five boys and one in four girls aged two to fifteen in England are overweight. But so far no treatments have proven effective in treating children.
The Mandometer was developed in Sweden, but at present is experiencing further development at the University of Bristol, with $ 224,400 in funds from BUPA-a global health and care organization. The system could be on the market in two years’ time. At first, it would be managed by medical clinics(诊所).

Using a computer or smartphone at night can cause us to pile on the pounds，new research has revealed．
The study found a link between blue light exposure(blue light is produced by smartphones and computers)and increased hunger．It found that exposure to blue light increases hunger levels for several hours and even increases hunger levels after eating a meal．Blue light exposure has also already been shown to cause decreased sleepiness in the evening，increasing the risk of sleeplessness．
The leading researcher，Ivy Cheung，from Northwestern University in Chicago，said，“A single three-hour exposure to blue-enriched light in the evening greatly affected hunger and metabolism(新陈代谢)．These results are important because they suggest that controlling environmental light exposure for humans may represent a novel approach of influencing food intake patterns and metabolism．”
The study group consisted of 10 healthy adults with regular sleep and eating schedules. They completed a four-day trial under dim(昏暗的)light conditions，which involved exposure to less than 20 lux(勒克斯，照明单位)during 16 hours awake and less than 3 lux during eight hours of sleep．On the third day they were exposed to three hours of 260 lux，blue-enriched light starting10.5 hours after waking up．and the effects were compared with dim light exposure.
Ivy Cheung said more research is needed to determine the functions involved in the relationship between light exposure，hunger and metabolism．What is Paragraph 2 mainly about?

Matthew Henson-Arctic Explorer
In 1880，fourteen-year-old Matthew Henson loved to hear sailors tell tales of their exciting 1ives at sea．The travel，the adventure，the danger，and the steady pay were all attracting young Henson．One day，he found a job as a cabin boy off a beautiful ship called the Katie Hinds．For the next five years．Henson sailed around the world．With the help of the ship’s captain and other members of the crew．Henson learned mathematics，navigation，history，geography，and many other subjects．By the time he left the Katie Hinds in 1885，Henson was well educated and had become an excellent seaman．
Unable to find work anywhere else，Henson took a job in a hat shop in Washington，D．C．One day in 1887，a man came in to buy a hat．The man，Robert Peary，asked the owner if he knew anyone with experience at sea．Peary would soon travel to South America for the U．S．government．He needed experienced men to accompany him．The shop owner knew about his young employee’s skills and experience on ocean journeys，so he introduced Peary to Henson．
Using his map-reading and sailing skills，Henson proved himself to be a worthy and smart seaman．Peary soon made Henson his assistant，and they became close friends．One day Peary told Henson about his real dream：to be the first man to stand on“the top of the world"at the North Pole．He asked Henson to help him make his dream come true．Over the next five years，the two explorers made two trips together to the Arctic．However，they were not able to reach the pole either time．The cold，wind，and ice were worse than either of them had ever imagined．
In 1908，Peary and Henson were ready to make their final attempt at reaching the North Pole．Both men were over forty years old．The years of hardship in the arctic cold had made them suffer a lot．This would be their last chance．With four Inuit guides，they made a mad rush straight across the ice toward the po1e．Peary’s feet were injured and he had to be pulled on a dogsled．In April 1909．Henson’s instruments showed they were standing at the North Pole．Together Henson and Peary planted the American flag in the snow．
In later years，Robert Peary and Henson were greatly honored for their achievements．Today，the two friends and fellow explorers lie in heroes’ graves not far apart in the Arlington National Cemetery．In paragraph 1，the author shows how Henson became________．

It was such an extremely freezing day that I decided to get a cup of hot drinking first after work．As my colleague，Ricky，and I were making our way to a coffee shop，I noticed an old gentleman rather poorly dressed sitting on a bench nearby．Obviously he was frozen，seemingly one of the homeless or someone like that．
We joined the 1ine and waited to be served．Ricky handed the server a twenty-dollar bill， ordered three cups of hot coffee，and gestured the server to give one to the old gentleman outside on the bench as a favour．The server looked at Ricky，a little perplexed，without full comprehension of the request．Afterwards，there was a wonderful exchange between the server and the old man in need of some attention．I only wish I had taken a photo of the smiles on the both faces.
As I was thinking about this event later on，I wondered to myself why Ricky didn’t perform this act of kindness himself．I suspected that deep down in his heart he was hoping that this act of kindness might inspire others to do something for this old man as well．Absolutely beautiful!
There are many ways of thinking when we meet someone as the old man in need of kindness and attention．Perhaps he needs a little helping hand and thank God for my colleague who inspired the others to goodness as well．Oh，by the way，the last words Ricky told the server were，“There go I，but for the Grace of God．”What was the author’s impression of the old gentleman?
| A．He was a greedy man． |

| A．He didn’t know the old gentleman． |
| B．He was too shy to speak to strangers． |
| C．He tried to influence others to be kind． |
| D．He feared the old man would refuse his help． |
What the author really thinks absolutely beautiful is that_________.
| A．an act of kindness could go widespread |
| B．a cup of coffee could warm the old man |
| C．the server was very kind to customers |
| D．Ricky had created good impressions |
