Every night as the whole family fell asleep，Catalina would slide from home to the Cerro Tololo observatory(天文台)．Papa was the mechanic(修理工)of the observatory，but during the day Papa would not allow her to get closer to the telescopes there．Only at night，Catalina was allowed in with the permission of the night staff．
Catalina loved helping to service the grand telescopes，the eyes that look out into the universe．She wanted badly to be an astronomer someday．Adults never took her dream seriously．Even her father laughed，“Maybe you'll be hired to clean the offices．”
One day in library，Catalina was reading a plant journal when she stopped at the picture of an unusual white flower．“It's called wild carrot，” a Spanish astronomer，who she saw several times in the observatory，stood behind her．“Pretty，isn't it I've always liked that flower，because it looks like a galaxy．”
“A spiral galaxy(漩涡星系)，” she whispered．Blond eyebrows climbed the scientist's forehead．“Indeed．And what is your name，young lady？” he asked．
“I'm Catalina Solis．”
“Eduardo Solis's daughter The mechanic？”
“Yes，” she gave a look at him．“I want to be an astronomer when I grow up．”
He laughed kindly，no longer meeting her eyes，and patted her on the shoulder．“Yes，of course，my dear．Work hard in school，and it will happen．”
One evening，Catalina scanned the top of the observatory as usual．Suddenly she noticed the angle of the one-meter telescope was unusual．The telescope was pointed down，lower than she had ever seen it．Catalina learned from Papa how dangerous it would be．If left like it was，the telescope would move past its limit and be damaged．So without hesitation she got inside the observatory．
注意：1．续写词数应为150左右；
2．请按如下格式作答。
She saw the Spanish scientist buried in work there．____________

She saw the Spanish scientist buried in work there．Catalina walked gently towards the scientist，who happened to lift his head and noticed her．“Still want to know more about flowers，Catalina Solis？” Catalina shook her head and told the scientist her discovery about the telescope．Without any hesitation，the scientist stood up and approached the one-meter telescope，observing，checking and adjusting the angle of it．A couple of minutes later，he spoke at last，“Thank you，young lady．What you found is quite timely and crucial．Your are really a good candidate for an astronomer．”
The scientist's words meant a lot to her．She smiled so happily as it was the first time an adult had confirmed her dream．She made up her mind to run after her dream and nothing would stop her．The scientist invited her to work as an assistant，working with him．After years of hard work，Catalina，who had been equipped with abundant theory and practice，was admitted to an astronomy university．Her childhood dream finally became a reality．Nothing is impossible to a willing heart．However，to Catalina，it's the scientist's encouragement that pushed her so far．

1 / 6课时分层作业(十八)
Ⅰ．阅读理解
A
NASA has put Uranus front and center according to its latest report．Its top priority for the next decade of space exploration in solar system is spending several billion dollars on a new important mission to the outer planet．
Uranus deserves a closer look．Only one spacecraft，Voyager 2，has ever visited the seventh planet from the sun in 1986．The visit was short：Uranus was one stop on the 1986 tour of the solar system，and the spacecraft made its observations while on the move．What scientists are recommending now is a mission specifically designed to study everything about the Uranian system，including the planet，its moons and its rings．
One might assume that we are pretty familiar with our neighbor．However，even with the best space telescopes，it is difficult to study a planet that is twice as far from Earth as is Saturn，and much smaller than Saturn．Name any aspect of the Uranian system，and planetary scientists can give you a list of unanswered questions about it．Unlike the other planets，Uranus spins (高速旋转) on its side，possibly the result of a crash with an Earth-sized object long ago．This unique tilt(倾斜) causes the most extreme seasons in the solar system．
By getting to know Uranus，planetary scientists can learn about a class of planets called ice giants，one of the most common planets beyond our solar system．In order to know more about ice giants，scientists should examine more closely one of our own．They picked Uranus over Neptune for practical reasons．For example，Neptune，which since 2006 has had the distinction of being the outermost planet in our solar system，is farther．With the rocket systems currently in operation，Uranus is easier to reach．
Planetary scientists saw the mission as a breakthrough because little is known about ice giants．It's sure there are going to be lots of surprises once man gets there．
1．What can we learn about the 1986 visit to Uranus
A．It was costly but fruitful．
B．Uranus' moons were found．
C．It was specially designed．
D．Uranus was observed on the move．
2．What does the underlined “our neighbor” in paragraph 3 refer to
A．Moon． B．Earth．
C．Saturn． D．Uranus．
3．What makes the Uranus mission so important
A．More will be known about ice giants．
B．Uranus is a ringed planet like Neptune．
C．Uranus is the farthest planet that can be reached now．
D．The cause of Uranus' extreme seasons will be explained．
4．What is the main purpose of the text
A．To reveal the mysteries of Uranus．
B．To introduce an exploring focus of NASA．
C．To stress scientists' efforts at space exploration．
D．To discuss the possibilities of exploring Uranus．
B
The ISS orbits Earth at an average of 250 miles from the surface of Earth and completes 15.5 circles per day，once every 92 minutes．In other words，the astronauts see the sunrise and sunset 16 times every day!
The station is inhabited by astronauts conducting research in various fields，while also using it as an observatory to explore Earth and outer space．It is also intended to be a transportation center for spacecraft that are bound for the Moon，Mars and other interplanetary voyages．
The crew is not only responsible for the scientific experimentation and research being conducted onboard，but also the upkeep and maintenance of the vessel，a vessel that is continuously in motion and exposed to the worst possible elements．Such conditions are significant area of study for researchers．
The most common effect of space is the initial contact — getting used to such an alien environment．Astronauts are often seen to display anxiety or depression as they adjust to the novelty of space，according to post-psychiatric screenings of astronauts．Other causes of stress are the high pressure of work while being under frequent public observation，being away from home and family，and missing important events．
Sleep is another major factor that affects the mood and efficiency of the astronauts．Due to the irregularity in life and the constant rotation(转动) of sunrise and sunset，the circadian rhythm(生理节律) of the astronauts goes completely haywire，resulting in poor quality of sleep．The shuttle itself is noisy，with essential equipment always in operation to sustain the vessel．Half of all the astronauts onboard rely on sleeping pills to get some rest and manage to get an average 2 hours less sleep than when they're back on Earth．Sleep is so critical for functionality that 50% of all medicines taken by astronauts in orbit is to help them sleep better．Low-Earth Orbit living is a restless endeavor，indeed．
5．Which of the following is most likely to affect the astronauts' mood
A．Scientific experiments onboard．
B．Observation of outer space．
C．Interplanetary voyages．
D．Exposure to extreme conditions．
6．Which of the following can best explain the underlined phrase in the last paragraph
A．Return to normal．
B．Become out of control．
C．Go unnoticed．
D．Remain unchanged．
7．How can we describe the astronauts' life in the ISS
A．Highly-pressured．
B．Trouble-free．
C．Safe and sound．
D．Quiet and beautiful．
8．What is mainly discussed in the passage
A．The functions of the ISS．
B．The missions of the astronauts．
C．The mental challenges of living in the ISS．
D．The splendid view of space．
Ⅱ．应用文写作

Dear Mr Smith，
I am Li Hua，a student of yours．I'm writing to put forward the suggestion that our school set up an astronomy interest group．
Here are my reasons．First and foremost，many students are so keen on astronomy that even some of them dream of being astronauts in the future．What's more，such an interest group will certainly inspire students with enthusiasm to carry out some research about the universe，which will also do good to the study of astronomy．Last but not least，it can enrich students' school life and they can benefit a lot from it．
I am looking forward to your reply．
Yours，
Li Hua
Ⅰ．[语篇解读] 本文是一篇说明文。文章介绍了美国国家航空航天局根据其最新报告将天王星置于中心位置，并在未来十年的太阳系太空探索中，打算花费数十亿美元执行一项新的重要任务。
1．D [细节理解题。根据第二段中“Uranus was one stop on the 1986 tour of the solar system，and the spacecraft made its observations while on the move．”可知，1986年天王星被航天器在移动中进行了观测，故选D项。]
2．D [推理判断题。根据第二段中“What scientists are recommending now is a mission specifically designed to study everything about the Uranian system，including the planet，its moons and its rings．”可推知，此处画线词指代的是天王星，故选D项。]
3．A [推理判断题。根据倒数第二段中“By getting to know Uranus，planetary scientists can learn about a class of planets called ice giants，one of the most common planets beyond our solar system．”可知，研究天王星对研究冰巨星有帮助，可推理出使得天王星研究变得重要是因为更多关于冰巨星的信息将被了解，故选A项。]
4．B [主旨大意题。根据第一段及全文可知，本文的主要目的是介绍美国国家航空航天局的一个探索重点，故选B项。]
[语篇解读] 本文是一篇说明文。文章介绍了国际空间站的宇航员面临的精神方面的挑战。
5．D [推理判断题。根据第三段中“exposed to the worst possible elements．Such conditions are significant area of study for researchers”和第四段前两句可知，暴露在太空的极端环境中最有可能对宇航员的情绪产生影响。故选D。]
6．B [词句猜测题。从画线部分前“circadian rhythm”和其后结果状语“resulting in poor quality of sleep”可推知，宇航员的生理节律紊乱或失去控制会导致糟糕的睡眠。故画线部分goes completely haywire意为“完全失控”，与become out of control同义。故选B。]
7．A [推理判断题。根据第三、四、五段可知，国际空间站的宇航员要适应一个全新环境，还要做各种实验和研究，压力是很大的。故选A。]
8．C [主旨大意题。根据全文内容，尤其是最后两段内容可知，本文主要讲述了在国际空间站里生活对宇航员精神上的挑战，故选C。]
