If you dream of going someplace warm to escape the cold winter weather,a trip to a recently discovered planet would certainly warm you right up.The planet,named
OGLE-TR-56b,has temperatures of more than 3,000°F.“This is the hottest planet we know about,”says Dr Dimitar Sasselov,a scientist who led the discovery team.“It is hot enough to have an iron fog and to rain hot iron droplets(细沫).”
The new planet is 30 times farther away than any planet discovered by scientists
before.It is in the Milky Way(银河)but it is not in our solar(太阳的)system.The new planet moves around a star much like our sun,however scientists discovered the planet by using a new planet?searching method called transit technique.They were able to catch sight of the planet when it moved in front of its star,causing the star's light to dim(变暗).Scientists compare the method to discovering the shadow of a bee flying in front of a searchlight 200 miles away.“We believe the door has been opened wide to go and discover planets like the Earth,”says Sasselov.

People born in the autumn live longer than those born in the spring and are less likely to fall chronically(经常) ill when they are older, according to an Austrian scientist.

As we know, it is common for people to catch a cold in winter and most people believe they know the reason for colds. However, scientists say people have some wrong beliefs about the cause of colds.
Many people think that once you get infected by colds, you will not be easy to be attacked by colds for the rest of your life. That’s not the case. There are about 200 different viruses that cause the common cold. You catch a cold because of one kind of them this time, but you might catch a cold next time because of another.
Others believe that people get sick just because of the cold weather in winter. That is also wrong.
It’s because people tend to stay closer in winter and the cold virus is transmitted from one person to another through handshakes, sneezing, or coughing.
While there is no actual cure for the common cold, scientists say there are still a few things you can do to help you. Some experts say honey and chicken soup are effective against colds. Especially honey. There is increasing evidence that it helps shorten the duration of the common cold sometimes even by two to three days particularly in children. Chicken soup also helps reduce the duration of the cold.
In addition, if you do have a cold and you don’t feel like eating anything, it’s not going to hurt you but you have to drink a lot and you can drink water or tea because doctors say the water cycle in your bodies helps to cure colds. That’s very important. Though there is more than one way to deal with colds, doctors say the best advice is to continue using whatever works best for you.

A．the common cold is caused by only one virus

A Swedish man was dug out alive after being snowed in his car on a forest track for two months with no food, police and local media reported on Saturday.
The 45-year-old from southern Sweden was found on Friday, February17, too weak to say more than a few words.
He was found not far from the city of Umea in the north of Sweden by snowmobilers who thought they had come across a ruined car until they dug their way to a window and saw movement inside.
The man, who was lying in the back seat in a sleeping bag, said he had been in the car since December 19.
“Just incredible that he’s alive considering that he had no food, but also since it’s been really cold for some time after Christmas.” a rescue team member told regional daily Vasterbottens- Kuriren, which broke the news.
Ebbe Nyberg, duty officer at the Umea police, said police saw no reason to doubt that the man had been stuck in the car for a very long time.
“We would not make up something like this. The rescue services were on site too and saw the same as us.” he told Vasterbottens-Kuriren.
Umea University Hospital, where the man is recovering after being rescued by police and a rescue team, said in a statement he was doing well considering the circumstances.
Doctors at the hospital said humans would normally be able to survive for about four weeks without food. Besides eating snow, the man probably survived by going into a dormant-like(休眠似的) state, physician Stefan Branth told Vasterbottens-Kuriren.
“A bit like a bear that hibernates. Humans can do that.” he said. “He probably had a body temperature of around 31 degrees which the body adjusted to. Due to the low temperature, not much energy was used up.”
“Why the man ended up under the snow in the forest remains unknown,” police said.

3.The reason why the man could survive was most probably that .
A．he was only forty-five year old B．he did not use any energy
C．he slept in the sleeping bag D．he was in a dormant-like state

a．The Swedish man was stuck in the snow. b．He was sent to Umea University Hospital.
c．He was found by snowmobilers. d．He was recovering after treatment.
