One day, she cooked the food in a heated earthen pot. And she was so surprised4.(find) that the food was will hot when she got to the island. After5.careful study, she found two secrets; there was thick chicken oil on the surface of the soup and the earthen pot did not6.(ready) conduct heat. As a result, the heat of the soup7.(preserve) well.
Since then, the scholar became8.(healthy) and more hardworking. Finally he succeeded in a government ?. He treated his fellow scholars9.the nice noodles with chicken soup. They praised it repeatedly and asked10.the splendid meal was. Thinking of he stone bridge she crossed every day, the wife blurted out (脱口而出) "crossing-over bridge rice noodles".

People all over the world have some strange hobbies, and one of the most unusual in Britain is "trainspotting". 1..You'll see the grown.ups standing around a railway stations and other places where trains pass by, and you'll see them taking photos and exchanging notes with each other. So, what are they doing?
2. - the numbers on the front of the trains, or the make and model of the "locomotive (火车头)" -the part of the train which pulls all the other part. In the same way that some people collect toys or stamps, these men collect and exchange all kinds of details about trains and railways.
The idea goes back as far as 1942. That year, a young man named Ian Allan was working at Waterloo railway station in London.3., and quite a lot of the questions he received were very similar. He found himself getting a little annoyed at sending the sine replies to the same questions .so he had a word with him boss. He asked if he could write a brochure giving the answers to the most frequently asked questions. His boss said if he wanted to waste his time on such a project, that'OK.4..So he did. The brochure he wrote was the earliest version of the FAQs (常见问题) you see on websites nowadays.
The first 2,000 copies were all sold in days, and by the 1950s, a million copies of British Railways Locomotives were selling every year. Ian Allan went to become a successful publisher, and got an Order of the British Empire(OBE,大英帝国勋章) from the Queen in 1995.5..
A.But he should do it in his own time
B.The young man spent much time on it
C.They're looking for the trains they've taken
D.Well, they're collecting information about trains
E.It's usually men over the age of 40, but not always
F.He died in 2015, but his trainspotting hobby lives on
G.It was his job to answer letters from people about trains
The United States space agency, NASA. says its Mars exploration vehicle recently recorded a high level of methane (甲烷) gas on the planet. The discovery is exciting because the presence of methane gas could support the case for life on Mars.
NASA's Curiosity vehicle recently recoded the largest level of methane ever measured during its seven-year Mars mission.
Methane has no color or smell. A special instrument on Curiosity's Man Science Laboratory recorded the increased gas level. The device measures levels of chemical elements and gases in the Marian atmosphere. In addition to methane, the instrument can record levels of water and carbon dioxide.
Nearly all the methane gas found in Earth's atmosphere is produced by living thing. It usually comes from animal and plant life. But it can also be formed by geological(地质的) processes, such as interactions. between rocks and water.
It was not the first time Curiosity had found methane gas in the Martian atmosphere. About a year ago, NASA announced that Curiosity had discovered sharp seasonal increases in the gas. This time, NASA said the measured methane gas level was clearly larger than any others observed in the past. "It's exciting because microbial (微生物的) life is an important source of methane on Earth," NASA said in a statement announcing the discovery.
However, Curiosity's team carried out a follow-up methane experiment that showed a sharp drop in levels of the gas. That number was "close to the background levels Curiosity sees all the time." NASA said. The rise and fall of the methane gas levels left NASA scientists with more questions than answers.
"The methane mystery continues," said Ashwin Vasavada. Curiosity's project scientist, "We're more motivated than ever to keep measuring and put our brains together to figure out how methane behaves in the Marian atmosphere."
1.What do we know about methane go?
A.It is a must to living things. B.It can be found everywhere.
C.It smells like carbon dioxide. D.It's mainly from biological activity.
2.What do the explorations on Mans tell us?
A.Humans have known much about Mars.
B.There will be more methane gas on Mars.
C.There is no progress in the 7 year's research.
D.The level of methane gas on Mars is not stable.
3.What does the discovery mean in NASA's view?
A.There may exist life on Mars.
B.Methane gas on Mars has a sudden increase.
C.The mystery about Mars will be solved soon.
D.They're known how methane as is formed on Mans.
4.How do the NASA's scientists feel about their future exploration?
A.Aimless. B.Confident.
C.Stressed. D.Serious.
Sea otters (海獭) are pretty small compared to other marine mammals (哺乳动物).which means that, despite their fur coats, they tend to lose het quickly, and need lots of energy to keep up their body temperature.
"So they need to eat 25 percent of their body weight each day," says Sarah McKay Strobel, a sensory ecologist at UC Santa Cruz. "But in order to eat that much food, that means sea otters need to find all that food. " She studied the otter's senses, to solve the mystery of how they're such efficient food catchers. Vision isn't reliable, she says- it's pretty dark and muddy underwater, and crabs and other smaller animals tend to hide. Hearing is also tough for otters, in the noisy underwater environment. And sniffing's no good either. "When they're underwater they're holding their breath."
What's left is touch. So Strobel measured the sensitivity of the otters' paws and whiskers (须). She blindfolded an otter named Selka, then presented it with plastic plates carved with tiny grooves (沟槽). Selka's job was to select the plate with two-millimerter grooves, which she'd been trained to associate with tasty food, instead of plates with differently sized grooves.
Tums out, Selka could tell just a quarter millimeter difference in the grooves' with with her paws - above and below water - and hall a millimeter difference with her whiskers. "The fact that she was able to perform so well while moving extremely quickly I think is really interesting and suggests that sea otters have very quick decision-making abilities and very quick sensory processing abilities, which makes sense when you think about the type of lifestyle they lead and how quickly they need to find food."
For the record, humans can feel the difference too, but it takes us 30 times longer, which might make sense. After all, we live in environments where touch is less important in a hunt than sight and sound.
1.Why do sea otters eat much food?
A.To swim faster. B.To stay warm.
C.To keep their fur thick. D.To satisfy their good appetite.
2.What does paragraph 3 mainly talk about?
A.An introduction to Selka. B.The use of plastic plates.
C.An experiment on Selka. D.The function of otters' touch.
3.What did Strobel find about sea otters' senses?
A.Hearing is useless. B.Touch is the most elective.
C.They have no vision. D.Their smell works very well.
4.What can we learn from the text?
A.Sea otters have enough food to eat.
B.Humans are more sensitive than sea otters.
C.Sea otters respond very quickly in hunting.
D.Sea otters' whiskers work better than paws.
