A team of Japanese adventurers say they have discovered footprints they believe were made by the legendary yeti said to roam (游蕩) the Himalayan regions of Nepal and Tibet.
“The footprints were about 20 centimetres (eight
inches) long and looked like a human’s,” Yoshiteru Takahashi, the leader of the
Yeti Project
Takahashi was speaking after he returned with his seven-member team from their third attempt to track down the half-man-half-ape, tales of which have interested Western adventurers and mountaineers for decades.
Despite spending 42 days on Dhaulagiri IV―a 7,661-metre peak where they say they have seen traces of yetis in the past―the team failed in their prime (最初) objective of capturing one on film.
But Takahashi said the footprints were proof enough.
“Myself and other team members have been coming to the
“We remain convinced it is real. The footprints and the stories the local tell make us sure that it is not imaginary,” he added.
Photographs of the prints have been posted on the expedition’s website, www.everest.co.jp/yeti2008/.
The team had set out nine motion-sensitive cameras in an area where Takahashi saw what he thought was a yeti during a previous expedition in 2003.
“It was about 200 metres away in silhouette (輪廓). It was walking on two legs like a human and looked about 150 centimetres tall,” said Takahashi.
Despite their lack of success this time, the team plans to continue the search.
“We will come back as soon as we can, and we will keep coming back until we get the yeti on film,” said Takahashi.

Researchers at Ohio State University say sheep probably respond more to good care than any other animal. So the first thing people should ask themselves is whether they have enough time to give sheep the attention they need.
If the answer is yes, then a question is how many sheep to buy. Specialists at Oklahoma State University suggest starting with a small flock (群)―twenty to fifty females.
Consider your budget. Do you have enough money for supplies? Do you have the things you need to take care of barns and pasture (牧場) lands?
There are other basic questions to answer when getting started.
What kind of sheep do you want to raise? There are wool breeds and meat sheep and dual-purpose sheep which can be used for wool or food.
Find out what products people in your area want to buy. Is there greater demand for fresh lamb than warm woolen sweaters? What about demand for sheep’s milk for making cheese? Research what kinds of markets are available.
If pasture lands are limited, sometimes two ewes and a cow can be placed together. Susan Schoenian at the University of Maryland says sheep will eat weeds that cows reject.
Sheep may need hay and grains, but pastures with enough good grasses and weeds can often supply much of their diet. Sheep are good for the land when they feed on grasses. It helps renew pastures and it can keep land from returning to forest.
Sheep need a structure that will keep them dry. A barn where newborn lambs are housed should be well protected from the wind. Also, fences should be strong enough to hold energetic little lambs.
60. According to the text people must consider first if they want to raise sheep.
A. whether they have enough money for supplies
B. how many sheep they want to buy
C. whether they have enough time to look after sheep
D. whether they have the things they need to take care of barns
61. We can infer from the text that .
A. cows will eat weeds that sheep reject according to Susan Schoenian at the University of Maryland.
B. the kind of sheep people want to raise must depend on what products of sheep market demands.
C. sheep are harmful to the land when they feed on grasses.
D. a barn where newborn lambs are housed should let the wind in.
62. The underlined word “ewe” (Paragraph Seven) here probably means .
A. female sheep B. male sheep C. little lamb D. horse
63. If you raise sheep, it is important .
A. to keep them wet B. to keep them active
C. to take special care of their feet D. to keep them dry

61. B. 由文章第六段的“Find out what products people in your area want to buy.及Research what kinds of markets are available.”判斷得知。
62. A. 由文章第二段的“starting with a small flock―twenty to fifty females”及第七段的“sheep will eat weeds that cows reject”判斷得知。

LONDON―Maths is not being taught well enough in many English schools with too much emphasis placed on “teaching to the test”, government inspectors said on Friday.
The report by Ofsted found that despite improving exam results, teaching in almost a half of all maths lessons was only satisfactory or worse and pupils did not achieve the necessary understanding.
“Too many schools are not teaching mathematics well enough,” said Ofsted Chief Inspector Christine Gilbert.
“The way mathematics is taught can make a huge difference to the level of enthusiasm and interest for the subject.”
Ofsted, which based its findings on a study of 192 schools, said 11 percent of maths lessons were outstanding, 44 percent good and 40 percent satisfactory, a level which commentators (評論員) said implied they were not up to scratch.
Six of the nine schools where teaching was not enough were secondary schools, the report said.
While results in SATs exams and GCSEs have improved, pupils were not being left with the required skills, it added.
“Many schools, particularly secondary, are not teaching mathematics well enough because they place too much emphasis on routine exercises and on ‘teaching to the test’”, the report said.
“While this style of teaching prepares pupils to pass examinations ... it is less effective in promoting the required understanding to apply mathematics to new situations, solve problems and communicate solutions.”
Earlier this year the government announced a 140 million pound strategy (策略) to increase the number of maths teachers, make lessons more exciting and improve exam results.
68. We can infer from the text that teaching in mathematics .
A. was weaker in primary schools than in secondary schools
B. was stronger in primary schools than in secondary schools
C. was outstanding in primary schools
D. was outstanding in secondary schools
69. The underlined words “up to scratch” (Paragraph Five) here probably means .
A. understandable B. believable C. doubtful D. satisfactory
70. The purpose of the government investing 140 million pound in measures was .
A. to transform the standard of maths teaching
B. to increase the wages of maths teachers
C. only to make lessons more living and interesting
D. to place much emphasis on regular exercises
71. The main purpose of this text is to tell people .
A. too much schools maths ‘taught to solve problems’ in England
B. many English children don’t like maths
C. maths is the most subject to many English children
D. too much schools maths ‘taught to the test’ in England
68. B. 由倒數(shù)第三段的“Many schools, particularly secondary, are not teaching mathematics well enough”判斷得知。
69. D. up to scratch令人滿意。
70. A. 由文章最后一段判斷A項是正確的。
71. D. 文章主要描寫了英國很多學(xué)校的數(shù)學(xué)教學(xué)是為了應(yīng)付考試。

People who eat quickly until full are three times more likely to be overweight, a problem exacerbated (惡化) by the availability of fast food and the decline of orderly dining habits, Japanese researchers said on Wednesday.
The findings, published in the British Medical Journal, highlight how eating styles, and not just what or how much is eaten, can contribute to an obesity epidemic (流行病) fueled by the spread of Western-style affluence in many parts of the world.
The World Health Organization classifies around 400 million people as obese, five percent of them under the age of five. The condition raises the risk of diseases like type 2 diabetes, heart problems and stroke.
For their study, Hiroyasu Iso and colleagues at Osaka University asked more than 3,000 Japanese volunteers aged 30 to 69 about their eating. About half of the men and a little more than half of the women said they ate until full. About 45 percent of the men and 36 percent of the women said they ate quickly.
Those who said they ate until full and ate quickly were three times more likely to be fat than people in the “not eating until full and not eating quickly” group, the researchers found.
They cited (引證) as causes both the availability of cheap food in big portions (份) and habits like watching television while eating.
To counteract (抵消) the “supra-additive effect” of speedy or glut (過量) eating among children likely to obesity, parents should encourage them to eat slowly and in calm surroundings, the study found.
72. The researchers gave special attention to the obesity epidemic caused by .
A. eating time B. eating food C. eating style D. eating place
73. Which of the following is not the health problem related to obesity according to the text?
A. heart disease B. stroke C. type 2 diabetes D. toothache
74. There are about million of children under the age of five as obese according to the World Health Organization.
A. 400 B. 80 C. 20 D. 5
75. What would be the best title for the text?
A. Speedy eaters seen likelier to get fat
B. Pay attention to eat quickly until full
C. Overweight people are more in the world
D. Most children are likely to be overweight
72. C. 由文章第二段的“……h(huán)ighlight how eating styles,……can contribute to an obesity epidemic”判斷得知。
73. D. 由文章第三段判斷得知。
74. C. 由文章第三段判斷得知。400 million × 0.05 (five percent) = 20 million
75. A. 本文是圍繞“吃飯?zhí)焯栆追逝帧眮砻鑼懙摹?/p>

Dear Mary,
I’m very glad to tell you something about China’s two manned spacecrafts Shenzhou VI and Shenzhou Ⅶ.
China launched its second manned spacecraft Shenzhou VI on Oct 12, 2005, sending two astronauts into space. The astronauts, Fei Junlong and Nie Haisheng, carried out many experiments and returned to the earth on Oct 17, 2005, which proves China has become a global space country.
On Sept 25, 2008 three Chinese astronauts, Zhai Zhigang, Liu Boming and Jing Haipeng were sent into space by China’s third manned spacecraft Shenzhou Ⅶ. They landed safely on Sept 28, 2008. During the flight, the three astronauts carred out many scientific experiments in space. Above all Zhai Zhigang walked in space with the help of Liu Boming, making China the third country to conduct a spacewalk after the United States and Russia.
Yours,
Li Ping

電子云（運(yùn)動特征）：電子在原子核外空間的一定范圍內(nèi)高速、無規(guī)則的運(yùn)動，不能測定或計算出它在任何一個時刻所處的位置和速度，但是電子在核外空間一定范圍內(nèi)出現(xiàn)的幾率（機(jī)會）有一定的規(guī)律，可以形象地看成帶負(fù)電荷的云霧籠罩在原子核周圍，我們把它稱為電子云。
電子層：在多個電子的原子里，根據(jù)電子能量的差異和通常運(yùn)動的區(qū)域離核遠(yuǎn)近不同，把電子分成不同的能級，稱之為電子層。電子能量越高，離核越遠(yuǎn)，電子層數(shù)也越大。

② 原子核外電子排布規(guī)律
每一層電子數(shù)最多不超過2n2 ；
最外層電子數(shù)最多不超過8個，次外層電子數(shù)最多不超過18個，倒數(shù)第三層不超過32個；
核外電子總是先占有能量最低的電子層，當(dāng)能量最低的電子層排滿后，電子才依次進(jìn)入能量較高的電子層。
