Chang"e I, China"s pioneering lunar probing (月球探测) satellite, came through its first lunar eclipse (月食)
yesterday and had regained full operations.
The moon orbiter was temporarily hidden from solar rays and lost 1 with Earth for two-and -half hours
during a blackout that started at 10 a.m., Ye Peijian, chief commander and designer in 2 of the satellite
system, said.
Chang"e I had to switch off some its 3 and rely on onboard batteries during this challenging time, when
it was 4 from solar energy, Ye said.
Full details of how Chang"e I 5 during the eclipse were due to be released last night.
Gu Shen, a deputy (副) director with the lunar probe"s measurement and control system, said scientists 6
the orbit of the satellite and shortened the 7 the probe was out of direct sunlight by about 80 minutes.
As of 10 pm. Wednesday, the satellite had 8 1204 orbits of the moon.Before yesterday"s eclipse, the 9
time Chang"s I had been without contact with the Earth was 49 minutes.
The European Space Agency helped 10 the satellite, which will perform a second orbital adjustment during
another eclipse in August, Ye said. |

passage. Write NO MORE THAN THREE WORDS for each answer. | Learning style theory suggests that different people have different ways of obtaining information and use
various methods to demonstrate (证明) their intelligence and ability. Although experts have many ideas and
categories of learning, it is evident that people learn in three basic styles.
When learning something new, if you prefer to read the information, you are probably a student who
learns through seeing. These learners like to see teacher"s facial expressions and body language clearly and
rend to sit at the front of the classroom. They take detailed notes, think in pictures and can most easily absorb
information from textbooks with diagrams, graphs, photographs and drawings.
Students who find it easiest to learn a new concept by hearing a teacher explain it are learning through
listening. Reading aloud, using a tape recorder, hearing anecdotes (趣闻) and talking things through are the
best methods for these learners to acquire new information. They give close attention to both the content of
the discussion and the way that things are said, such as how the sound of the voice and speed of speech
show the mood of the speaker.
Learning through doing means being active in exploring the environment and finding out about things by
moving and touching. Students who have this learning style take a hands-on approach to education and enjoy
experiments or surveys. They do not like to sit still for long periods of time and sometimes find it hard to
concentrate when reading or listening.
Teachers study people"s various ways of learning as part of their training. They select a variety of
activities to suit their students" different learning styles. However, restrictions of time, space and resources
often make it impossible for teachers to provide the best exercises for all learners. If you are aware of you
own learning style, there is a lot you can do personally to improve your study skills and find the most
appropriate ways to approach your study tasks. As a result, you will be able to manage your own learning
and study more effectively. | | 1.______ | Features of students" learning | | Learning through seeing | *watch a teacher"s facial expressions and body

passage and the required words limit. | Even plant can run a fever, especially when they"re under attack by insects or disease. But unlike human,
plants can have their temperature taken from 3,000 feet away straight up. A decade ago, adopting the infrared
(红外线) scanning technology developed for military purposes and other satellites, physicist Stephen Paley
came up with a quick way to take the temperature of crops to determine which ones are under stress. The
goal was to let farmers precisely target pesticide (***虫剂) spraying rather than rain poison on a whole field,
which invariably includes plants that don"t have pest (害虫) problems.
Even better, Paley"s Remote Scanning Services Company could detect crop problems before they became
visible to the eye. Mounted on a plane flown at 3,000 feet at night, an infrared scanner measured the heat sent
out by crops. The data were transformed into a color-coded map showing where plants were running "fevers".
Farmers could then spot-spray, using 50 to 70 percent less pesticide that they otherwise would.
The bad news is that Paley"s company closed down in 1984, after only three years. Farmers resisted the
new technology and long-term backers were hard to find. But with the renewed concern about pesticides on
produce, and refinements (改进) ininfrared scanning, Paley hopes to get back into operation. Agriculture
experts have no doubt the technology works."This technique can be used on 75 percent of agricultural land
in the United States," says George Oerther of Texas A& M, who recently retired from the Department of
Agriculture, thinks remote infrared crop scanning could be adopted by the end of the decade. But only if Paley
finds the financial backing which he failed to obtain 10 years ago. | 1. In what situation will plants have a fever? (No more than 8 words)

the world"s tiniest fish. The little creature was found recently in an Indonesian swamp (沼泽).
For now, the fish is known as Paedocypris progenetica. It has a transparent, or see-through, body. Its head
doesn"t have a skeleton (骨架), leaving its brain vulnerable (脆弱的) to its surroundings. The fish, which is
female (雌性的), can grow to be only 7.9 millimeters or (0.31 inches) long, about the size of a large mosquito
(蚊子).
Maurice Kottelat, a fish expert from Sweden, led the team of researchers that made the discovery. Kottelat
and his team reported their discovery in the Proceedings of the Royal Society, a British scientific journal.
"You don"t wake up in the morning and think today we will find the smallest fish in the world," said Kottelat
in an interview. He and his team were most excited by the possibility of having discovered the world"s smallest
vertebrate. "What"s important is finding a complete backbone in a body so small," said Kottelat. All fish, reptiles
(爬行动物), birds, and mammals (including humans) are vertebrates.
It wasn"t long after Kottelat"s announcement that another researcher challenged the claim with a discovery
of his own. Fish expert Ted Pietsch, a researcher at the University of Washington, says that he has discovered
a fish that is smaller than Kottelat"s discovery.
According to Pietsch, the male Photocorynus spiniceps is a tiny ocean fish measuring only about a quarter
inch. That would actually make Pietsch"s fish the world"s smallest vertebrate. Kottelat"s would come in at a
close second. When Pietsch got in touch with Kottelat to mention the fish, four of which he keeps in his office-
Kottelat did not argue. He kindly gave the title of "world"s smallest vertebrate" over to Pietsch"s unique fish.
"So our little fish is only the smallest freshwater vertebrate," Kottelat wrote. "Now I wait until the next
smallest fish is discovered." | | 1. Pietsch"s fish is shorter than Kottlelat"s by about _____. | | [ ] | A. 0.01 inches
B. 0.06 inches
C. 0.1 inches
D. 0.31 inches | | 2. The underlined word "vertebrate" probably means "_____". | | [ ] | A. a creature in an ocean
B. a fish in fresh water
C. an animal that can swim
D. an animal with a backbone | | 3. Which statement is TRUE according to the text? | | [ ] | A. Kottlelat"s fish still keeps the record of the smallest fresh water vertebrate so far.
B. Pietsch"s record of discovery of the world"s smallest fish was soon broken by others.
C. Kettlelat didn"t admit that Pietsch"s fish was even smaller than his.
D. All fish, reptiles, amphibians, birds and humans share the same ancestor. | | 4. Which question doesn"t seem to be answered so far according to the text? | | [ ] | A. Is fish a vertebrate animal?
B. What"s the world"s smallest fish indeed?
C. What is the smallest freshwater vertebrate?
