Celebrate the moon landing anniversary with books
Astronomy lovers are not the only ones excited about the anniversary of the moon landing.Publishers are also taking note, serving up a pile of books to mark the occasion.
One Giant Leap, D|S29.99　Charles Fishman
Getting to the moon demanded a million hours of work for each hour spent in space, this book argues.Accordingly, the story focuses on the engineers, coders, project managers and others who worked hard to get the Apollo program off the ground.
Moonbound, D|S35　Jonathan Fetter Vorm
Colorful and detailed, the comic style illustrations (連環畫風格的插圖) in this book bring the moon landing to life.Much of the astronauts' dialog is based on real recordings, making the book particularly reliable.
The Apollo Missions, $19.99　David Baker
A former NASA engineer uses photographs, illustrations, blueprints and other documents to guide readers through a clear history of the space race and the Apollo program, from the beginnings of rocket science to the successful return home of the Apollo 11 crew.
The Mission of a Lifetime, $22　Basil Hero

For any spaceman hoping to survive on the surface of the moon, growing crops will be important.Now, scientists have taken “one small step” towards growing plants on the lunar surface, after showing it's possible to grow thale cress, a small flowering plant, in the lunar soil.
The findings raise hopes that plants could be grown on the moon during future space missions (任務), and even enable mankind to set up a lunar settlement.“For future, longer space missions, we may use the moon as a launching platform，” explained Professor Rob Ferl.“It makes sense that we would want to use the soil that's already there to grow plants.” Until now, scientists have not grown plants in the soil.“So, what happens when you grow plants in the lunar soil What would plants do in a lunar greenhouse Could we have lunar farmers？” Professor Ferl questioned.
To answer these questions, researchers from Florida set out to plant thale cress seeds in the lunar soil, add water, nutrients and light, and see what happened.The researchers chose to use thale cress because its genetic code (基因序列) has already been fully mapped.For comparison, the researchers also planted seeds in a range of soils, including those that are similar to the Martian soil.To their delight, the researchers found that nearly all of the seeds grew.However, they did observe differences between the plants grown in the lunar soil and those grown in the control soils.Some of the plants grown in the lunar soil were smaller, while others grew more slowly or were more varied in size.
Growing plants in the lunar soil may also change the moon itself, according to Dr.Stephen Elardo.“The moon is a very, very dry place，” he said.How will minerals in the lunar soil respond to having a plant grown in them, with the added water and nutrients Will adding water make the minerals friendlier to plants The researchers hope to answer these questions in follow up studies.

D．Making the Lunar Soil Friendlier to Plants
C
As much as we like to think about nature embodying balance, the universe is actually filled with imbalance, too.Let's take the supernova (超新星) for example.Two stars orbit each other.One of the stars is older, called a “white dwarf”， while the other star is a bit younger.Their mutual gravitational interaction (引力相互作用) pulls material off the younger star and dumps it onto the surface of the white dwarf.If enough material falls onto the dwarf, the stuff dumped onto the white dwarf begins to “burn”．
If the conditions are right, you always burn up the same amount of material that gets added.If the_donor_star is dumping too much material onto the dwarf, the burning runs out of control.It consumes not just the new material on the white dwarf's surface but the whole of the dwarf star itself.So much energy is released so quickly that the star finds itself wildly out of balance.In an instant, it becomes a super hot ball of unbalanced pressure, BOOM! A supernova is born.
Closer to home, a similar but different kind of process happens in volcanoes.Volcanoes are born when magma (熔巖) from deep in the Earth makes its way slowly to the surface through cracks in the planet's crust (地殼)．The heat from the magma builds up a massive pressure imbalance inside the mountain.It's that imbalance that drives the BOOM, the volcanic eruption that rips a zillion tons of rocks away and sends ash 15 miles into the sky.
But here's the thing: Supernova, volcanoes and all those other explosions in the universe are not just awesome sights.They are all essential players in cosmic (宇宙的) evolution.Supernovas create a lot of the elements in your body that are essential to life.No supernova, no you.And volcanoes are essential to evolution of the planet, including the cycling of greenhouse gases like CO2 that make Earth habitable.No volcanoes, no you.
8．What does the underlined phrase “the donor star” refer to in paragraph 2
A．The younger star. B．The older star.
C．The supernova. D．The white dwarf.
9．What factor leads to both the birth of supernova and volcanic eruption
A．Hot magma. B．Burning material.
C．Unbalanced pressure. D．Gravitational interaction.
10．What can we learn about the explosions in the universe in the last paragraph
A．They evolve as players. B．They create human bodies.
C．They are awesome sights. D．They are necessary to life.
11．In which section of a website can you find this text
A．Profile. B．Science.
C．Health. D．Economy.
D
The moon, which has experienced a distinct and complex geological history, presents a striking appearance. The moon may be divided into two major terrains：the Maria (dark lowlands) and the Terrace (bright highlands). The contrast in the reflectivity (the capability of reflecting light) of these two terrains suggested to many early observers that the two terrains might have different compositions, and this assumption was confirmed by missions to the moon such as Surveyor and Apollo.
One of the most obvious differences between the terrains is the smoothness of the Maria in contrast to the roughness of the highlands. This roughness is mostly caused by the abundance of craters：the highlands are completely covered by large craters, while the craters of the Maria tend to be much smaller. It is now known that the vast majority of the moon's craters were formed by the impact of solid bodies with the lunar surface.
Most of the near side of the moon was thoroughly mapped and studied from telescopic pictures years before the age of space exploration. Earth based telescopes can recognize objects as small as a few hundred meters on the lunar surface. Close observation of craters, combined with the way the moon diffusely reflects sunlight, led to the understanding that the moon is covered by a surface layer with strange,_winding_marks. Although various land forms were discovered, the majority of astronomers' attention was fixed on craters and their origins.
Astronomers have known for a fairly long time that the shape of craters changes as they increase in size. Small craters have relatively simple shapes. They have round edged tops that are raised above the surrounding terrain, smooth, bowl shaped insides, and depths that are about one sixth their diameters. The complexity of shape increases for larger craters.
12．What does the text mainly discuss
A．The aim of the Surveyor and Apollo space missions.
B．Characteristics of the major terrains of the moon.
C．The origin of the moon's craters.
D．Techniques used to discover the moon's land forms.
13．Why are the Surveyor and Apollo missions mentioned
A．To confirm earlier theories about the moon's surface.
B．To reveal that previous ideas about the moon's craters were unreasonable.
C．To provide detailed information about the moon's surface.
D．To identify how the moon's craters were made.
14．The author mentions “strange, winding marks” in paragraph 3 as an example of ________.
A．an aspect of the lunar surface discovered through lunar missions
B．a characteristic of large craters
C．a discovery made through the use of Earth based telescopes
D．features that astronomers observed to be common to the Earth and the moon
15．The last paragraph probably continues with ______.
A．some difference in the ways small and large craters were formed
B．the different shapes small craters can have
C．the reasons craters are difficult to study
D．the description of some features of large craters

Interesting Space Facts
As time goes by, technological advancements have made us learn more facts about space in the past century than in all time before that.We've already searched the universe for the most amazing space facts, including facts about the planets in our solar system, moons, the Milky Way and beyond! __16__
The highest mountain discovered is the Olympus Mons, which is located on Mars.It is 16 miles high, making it nearly 3 times higher than Mount Everest. __17__ That's the size of Arizona!
The sun weighs about 330,000 times more than Earth. __18__ In fact, the sun is so huge that it contains 99.85% of all mass in our solar system.
Footprints left on the moon won't disappear as there is no wind.But wait a minute.__19__ Well, it actually wasn't blowing.That blowing you see is because of a telescopic horizontal rod (望遠鏡水平桿) that the astronauts were struggling to remove from the flag's top.
__20__ This is due to the lack of gravity in space causing the vertebrae (椎骨) to expand a little.However, this extra height is lost when they re enter the Earth's atmosphere and are affected by the Earth's gravity again.
A．We're pretty sure they will make you interested!
B．New discoveries will no longer be made in the future.
C．It is so large that it can contain about 1,300,000 Earths!
D．Not only is it tall, but it's 114,000 square meters as well.
E．All these space facts may not be true at the time of writing.
F．Astronauts can grow about two inches in height when in space.
G．If there's no wind to blow them away, then why is the flag blowing

The Right Thing
My mother worked as a housekeeper and she was often given used toys as well as many other goodies by her clients.My elder sister and I always loved sharing the recycled books and board games brought home by my beloved mom, which we considered great gifts life presented us.
The long awaited Christmas finally approached.One December day, an old model toy car arrived in the load of goods.It was as long as my forearm and took both hands to lift.My sister didn't want it, so it was all mine.I immediately set down to wiping it clean and polishing it to a bright candy apple red.It turned to be a thing of beauty, and I became overjoyed at possessing it.My elder sister was amazed at the newly polished, refreshing toy car, with a hint of regret and envy in her eyes.
As was planned, our relatives from France came to visit us that Christmas.It was a time when the family bond got strengthened.I shared the prized toy car with Alex, my young French cousin.Eyes glued to it, he fell in love with the wonderful, shiny red automobile the instant he saw it.It was a rare moment to see him feeling so relieved and happy.He'd been unlucky so far in life, suffering severe life threatening illnesses as a child, leaving him mentally and physically stuck and the family starved of cash.Of course, such lovely toys like my dear model car were unreachable dreams for him.
Seeing Alex's consuming thrill brought by the red car, I was seized by immense joy as well.But contrary to Alex's excitement, a voice inside me constantly reminded, “Watch out! He'd keep it for himself.”， which got me faintly worried.I followed my cousin for fear of something.
My mother also noticed Alex's fondness for the car.Approaching me, she asked gently in a low voice, “Would you like to give it to Alex？”

第一節　參考范文：
Space Exploration Lights up Dreams
April 12 was officially named by the UN in 2011 as World Space Day.We observe this day to inspire more people to learn scientific knowledge and generate innovative ideas about space.
The space exploration is essential for us.It has made a difference in fighting world hunger.The satellite data on weather patterns has helped farmers grow more food.Besides, many space experiments have promoted incredible products like organ monitors and digital cameras for us and we will learn how to live in a different environment.
Our progress in space exploration gives me hope and inspires me to make contributions to it.I dream of people living in the space one day and building a shared community there.
第二節　參考范文：
Giving or keeping I struggled with myself.Giving it Hardly could I imagine life without the model car! After all, it was my most precious treasure, which I had been proud of.My heart kept aching at the prospect of giving it away.Nope! I shook my head determinedly.Glancing at my mother's expectant eyes, I couldn't help sobbing.Keeping it Definitely, it would otherwise upset Alex.Torn between the two tough choices, I was totally at a loss.Nevertheless, deep down, I could feel my affection to Alex.Yep! I resolved to do the right thing.
In the moment of parting, my model car went with Alex.Though I was crushed to see it go, my heart sang when I saw his beaming face as he tightly clutched it.Seeing the thumbs up from my mother and sister, I did swell with relief, pride and joy, for I knew it was not a gift; to some extent, it was our concern and love for him.Plus, sharing the model car also strengthened our bond, which, I was fully convinced, would always uplift him.An effort made for the happiness of others lifted us above ourselves as well.
