My name is Clara.I still remember that chilly December day,sitting in science class.I’d finished a worksheet early and picked up a TIME for Kids magazine. A piece of news caught my eye:NASA was holding an essay contest to name its Mars rover(火星探测器).Before I even knew anything else about it,a single word flooded my 11-year-old mind,Curiosity.
I couldn’t want for the bell to ring so I could get started on my essay.That afternoon,I raced home,sat down at the computer,and typed until my fingers ached. “Curiosity is an everlasting flame that burns in everyone’s mind...”
Five months later, my mon received a phone call,and immediately, a wide smile spread across her face.
On August 5,2012,at 10:31 p.m,the rover named Curiosity touched down safely on the surface of Mars,and I was honored to have a front-row seat in NASA.
Curiosity is such an important part of who I am.I have always been fascinated by the stars,the planets,the sky and the universe. I remember as a little girl,my grandmother and I would sit together in the backyard for hours.She’d tell me stories and point out the stars,Grandma lived in China,thousands of miles away from my home in Kansas,but the stars kept us together even when we were apart.They were always there, yet there was so much I didn’t know about them.That’s what I love so much about space.
People often ask me why we go to faraway places like Mares.My answer is simple because we’re curious.We human beings do not just hole up in one place.We are constantly wondering and trying to find out what’s over the hill and beyond the horizon.How did Clara get the new about the essay contest?( no more than 10 words)
Why did Clara have a front-row seat in NASA?( no more than 10 words)
What does Clara remember about the time spent with Grandma?( no more than 15 words)
What does the underlined phrase “hole up”mean?(1 word)

Adult butterflies use their se
nses of sight, touch, hearing, smell, and taste to survive in the world, find food and mates, lay eggs in an appropriate place, migrate, and avoid hungry predators.
Sight
Butterflies have large, compound (multifaceted) eyes, which allow them to see in all directions without turning their heads. Like most insects, butterflies are very nearsighted, so they are more attracted to a large stand of flowers rather than individual plants. Butterflies do not "see" colors such as red, green, and yellow, but sense polarized（偏振的） light, which indicates the direction the sun is shining, as well as ultraviolet light, which is present on many flowers and guides butterflies to nectar （花蜜）sources.
Smell
Butterflies have a very well-developed sense of smell, but it's not in their nose (since they don't have one). Sense receptors located in their antennae, feet, and many other parts of the body help butterflies find food (usually flower nectar), and mates (the female smells the male's pheromones).
Taste
Butterfly's feet have sense organs that can taste the sugar in nectar, letting the butterfly know if something is good to eat or not. Some females also taste host plants in order to find appropriate places to lay their eggs. Adult butterflies and moths feed using a probo
scis, a long, coiled tube. Butterflies force blood into the tube to straighten it out, allowing them to feed. Butterflies get all their food from this tube.
Hearing
Butterflies don't have ears. Instead they "hear" sounds through their wings by sensing changes in sound vibrations.
Butterflies may possess senses we don't even know about yet because their anatomy is very different than ours, and therefore difficult to understand when perceived through our own human senses. From the passage we can know that butterflies can see_____
A．thing beh ind them |
B．thing in the distance |
| C．most bright colors | D．flower nectar from a distance |
Butterflies can easily find food resources by using their______.
| A．sense organs of sight and smell | B．sense organs of sight and taste |
| C．sense organs of smell and hearing | D．sense organs of smell and taste |
How do butterflies feed themselves?
| A．by using their feet | B．by using a tube. |
| C．by using sense receptors | D．by using their wings. |
What is the passage mainly about?
| A．The food sources of butterflies. | B．The habits of butterflies. |
| C．The unusual body of butterflies. | D．the sense of butterflies. |
In the long discussion of water on the Moon, a new study contradicts(与……相矛盾)) some recent reports that say the Moon had water at the time of its formation. A group of researchers reported in the journal Science that when the Moon was created, some 4.5 billion years ago, there was not much hydrogen(氢气) on it, and therefore no water.
The researchers surveyed and evaluated this by analyzing chlorine isotopes（氯同位素） found in lunar rock samples from Apollo missions. The range of chlorine isotopes in lunar samples was 25 times that found in samples from Earth.
If the Moon had significant levels of hydrogen, as Earth did, this range would have been far less, said Zachary D Sharp, a scientist in the Department of Earth and Planetary Sciences at the University of new Mexico and the study’s lead authour.
The chlorine would have stuck together with hydrogen, forming compounds like hydrogen chloride, and escaped from the Moon’s surface, he said. The abundance of chlorine indicates a lack of hydrogen and water.
“ The amount of water on the Moon was too low for life to possibly have existed there,” he said.
Most scientists believe the Moon was formed when a large object stuck 
Earth, breaking off a chunk(a vast piece) that has since orbited Earth.
On Earth, goes one theory, water was released as steam form molten basalts(玄武岩) over time, eventually forming bodies of water.
“An understading of whether the Moon was dry or wet will help us understand how water appeared on Earth,” Dr Sharp said. A new study indicates that _____ on the moorn.
| A．there is plenty of water | B．water is unlikely to exist |
| C．water existed in the past | D．there is a little water now |
The author would like to tell us ______ through the sixth paragraph.
| A．why there is no water on the Moon | B．how the Moon was formed |
| C．when the Earth struck the Moon | D．where the Moon orbited |
Which is NOT true according to the passage?
A. Zachary D. Sharp, a scientist of New Mexico was in charge of the new study.
B. Chlorine isotopes in lunar samples are 25 time larger than those on the Earth.
C. The more aboundant chloride, the shorter hydrogen and water.
D. The new study is benificial to understand how water appeared on Earth. What can we learn from the passage?
| A．There is enough water on the Earth. |
| B．Hydrogen chloride easily escaped from the Moon’s surface. |
| C．The Earth had significant levels of hydrogen. |
| D．Water on the Earth is directly from molten basalts. |
They leap from helicopters or speeding boats, bringing aid to swimmers who get into trouble off Italy’s popular beaches.
For these dog lifeguards, the doggie paddle （狗刨式游法）does just fine.
These “lifedogs” tow a buoy(救生衣) that victims can grab, or a raft they can sit on to be towed back to
shore, and unlike their human counterparts(与对方地位相当的人), they can easily jump from helicopters and speeding boats to reach swimmers in trouble.
With millions flocking(人群) to Italy’s crowded beaches each summer, the Italian Coast Guard says it rescues about 3,000 people every year — and their dog helpers are credited with saving several lives.
It takes three years for the canines to reach expert rescue status, and currently 300 dogs are fully trained for duty, said Roberto Gasbarri, who co-ordinates the Italian School of Canine Lifeguards program at a centre outside of Rome in the seaside town of Civitavecchia.
“Dogs are useful in containing the physical fatigue（疲劳） of the lifeguard, to increase the speed at which casualties（遇难者） are retrieved（找到并衔回）, to increase the security of both the casualty and of the lifeguard,” Gasbarri said.
The Civitavecchia centre is one of a dozen around the country for the school founded more than 20 years ago in the northern province of Bergamo by Ferruccio Pilenga, whose first trainee was his own Newfoundland.
The school will train any breed（品种）, as long as they weigh at least 30 kilograms, but Labradors, Newfoundlands and golden retrievers are most commonly used because of their natural instinct for swimming. Each dog works in tandem with（同 ……合作） a human lifeguard, who also acts as the animal’s trainer.Which of the following can act as the best title fo the passage?
| A．Dogs to the Rescue | B．Dogs Are Good at Doggie Paddle |
| C．The Wonderful Performance of Dogs | D．Dogs: Our Loyal Friends |
What advantage do these life-dogs have over human lifeguards in a rescue?
| A．Dog can swim very fast | B．Dogs can finish rescue work with ease. |
| C．Dogs can finish the great work free of charge. | D．Dogs can easily be trained |
Which of the following is TRUE about the Civitavecchia center according to the text?
| A．Any breed can be trained there. |
| B．The ones who have the gift for swimming are welcomed. |
| C．After a better training, the dogs can work alone. |
| D．It is the only place for training dog lifeguards in the school. |
What does the writer want to tell us in the 4th paragraph?
| A．Without the dog lifeguards, 3,000 people would lose their lives every year. |
| B．The buautiful beaches attract millions of people every year. |
| C．Dog lifeguards play an important part in a rescue. |
| D．Italy is a famous place of interest. |
One morning more than thirty years ago, I entered the Track Kitchen, a restaurant where everyone from the humbles(卑微的) to the most powerful came for breakfast. I noticed an empty chair next to an elderly, unshaven man, who looked somewhat disheveled. He was wearing a worn-out hat and was alone. I asked if I might join him. He agreed quietly and I sat down to have my breakfast.
We cautiously began a conversation and sopke about a wide range of things. We never introduced ourselves. I was concerned that he might have no money and not be able to afford something to eat. So as I rose to go back to the counter and buy a second cup of coffee, I asked.
