Strange Footprints in the Snow
Jonathan woke up and looked around．For a moment，he wasn't sure where he was．Then he remembered．He and his sister，Julie，were visiting Aunt Gwen．They had spent yesterday helping Aunt Gwen clean her basement．Today they would have time to play．
He looked out the window．Fresh snow covered the ground．He could hardly wait to go outside．Jonathan dressed and hurried downstairs to the kitchen．
“Hi，sleepyhead，” said Aunt Gwen．“Julie has already eaten her oatmeal．She's outside．”
“That's where I'm going as soon as I finish breakfast，” Jonathan said．
A short time later，he zipped up his coat，put on his boots，and walked out the front door．The sun made the snow sparkle．He looked around．He didn't see his sister，but he saw something else．Strange footprints in the snow tracked across Aunt Gwen's yard．
“They're way too big to be Julie's．They look like they belong to a dinosaur，” Jonathan said．Then he added，“But that's silly．Dinosaurs are not around anymore．”
He looked closer：The footprints were the shape of a very large oval(椭圆) with a stem．“Maybe they belong to an elephant or a hippo that escaped from the zoo，” he thought．He held his breath and listened．He didn't hear anything．
He remembered a book he'd seen earlier on Aunt Gwen's shelf．It was a book about animal tracks．He dashed inside to get it．The book had pictures of animals and the tracks they made．He turned the pages one by one，but none of the photos looked like the footprints in Aunt Gwen's yard．
He stared at those footprints again．An animal that made such big tracks would have to be heavy．Its tracks should sink far down into the snow．Yet these footprints seemed to skim across the top．
How can that be He wondered．
Jonathan noticed something else．The tracks never left Aunt Gwen's yard．Instead，they turned and went around the house．“Maybe the animal is still here，” he whispered．
注意：1．续写词数应为150左右；
2．请按如下格式作答。
Quietly，he began following the footprints．_________________

[参考范文]
Quietly，he began following the footprints．He didn't want to scare the animal away．There was nothing in sight except the strange footprints．Suddenly，there seemed to be some strange sounds ahead．Jonathan stopped and listened carefully．It came from the backyard．Thrilled，mixed with a little frightened，he quickened his pace! Swish，clomp，swish，clomp．The sound became clearer and clearer．Holding his breath，Jonathan peeked around the corner of the house．
That was when he saw her—his sister，Julie．She had something worn on both feet，which looked like giant tennis racket with short handles．She was walking on the snow back and forth happily．Noticing her brother，Julie waved excitedly，“See what I found in Aunt Gwen's basement They are old fashioned snowshoes．Aunt Gwen said the shape helped walk steadily on the snow．And that is true！” Jonathan then laughed，“No wonder I couldn't find those footprints in Aunt Gwen's book．” There was no page for a snowshoeing sister．

1 / 6课时分层作业(十五)
Ⅰ．阅读理解
A
At the foot of Egypt's Sinai mountains，once a small fishing town，Dahab is now one of the Red Sea's top diving resorts(潜水胜地)，attracting a lot of nature lovers．It also provides a stress-free seaside atmosphere where visitors can just sit back and enjoy its waters．There are affordable accommodations，tour operators，multicultural restaurants and cafes．
Dahab is also one of the few places in the area with internet access，making it attractive to remote workers looking for a peaceful “office” by the sea．Rahma Zein，who chose to go to Dahab on the advice of friends，said，“On a normal day，I wake up，make breakfast，go for a free dive，hang out on the beach，take a hike，eat and then sleep．” she added，“In between sessions，I make phone calls and do my work．”
Located on the edge of the Red Sea，the Blue Hole is one of Dahab's most famous sites and one of the world's most famous diving sites．Going down to a maximum depth of 328 feet and easily accessible from the shore，the Blue Hole is not influenced by the currents，so its waters are relatively calm．The conditions here are perfect for free divers，as well as advanced divers looking to push their limits in a race．
To reduce the traffic here，a local group of divers have created an underwater museum filled with giant statues made of recycled materials．The most impressive statue is a life-sized elephant weighing 700 kilograms which has gained the attention of countless tourists．
There are also limitless options in shallower waters for those who want to avoid crowded diving spots．Travellers can hike or ride camels to Ras Abu Galum National Protectorate，which covers 400 square kilometers of coastline and offers a better view of sea life．
1．What do we know about Dahab
A．It still is a small fishing town．
B．Life there is full of stress．
C．It attracts a lot of nature lovers．
D．Accommodations there are expensive．
2．Which of the following best describes Rahma Zein's life in Dahab
A．Relaxing． B．Boring．
C．Stressful． D．Lonely．
3．What can we learn about the underwater museum in Dahab
A．It is built by the local government．
B．There is a large elephant from Africa．
C．It aims to offer a better view of sea life．
D．There are statues made of recycled materials．
4．What's the purpose of this text
A．To recommend a sport．
B．To introduce a scenic spot．
C．To share a travel experience．
D．To call for environmental protection．
B
Dive into the classical world via the remains of an ancient merchant ship that dates all the way back to 5 BC as Greece is constructing its first underwater museum．
Some of Greece's vast heritage of ancient shipwrecks are accessible to the public (divers and non-divers) for the first time ever in a series of underwater museums．The first opened on August 3，allowing visitors to explore the “Peristera shipwreck”，which has been at the bottom of the Aegean Sea for more than two thousand years after it sank in the 5th century BC near the northern Greek island of Alonissos．Since a fisherman discovered the ship in 1985，it has remained off-limits to the public but now visitors can explore it by sea or by virtual reality．
Researchers believe it's the most important shipwreck from the classical era．It had been believed that a trading ship of that type didn't exist until the Roman era some 400 years later．So when it was discovered years ago，it completely changed our understanding of shipbuilding in the ancient world．
Experts have yet to determine how or why it sank although there are some indications that a fire may have broken out．It's believed that it was carrying 4，000 vases of wine when it sank，most of which are still lying on the seabed，along with fishes and some little creatures who now call it home．
Greece had banned diving until 2004 or so，due to worries that undersea ancient heritage would be taken away but now the country is wholeheartedly hugging its rich underwater heritage．Access to the Peristera shipwreck is available through a new project that will create underwater museums across the Greek islands over the next two years．Divers will be able to tour the shipwreck with licensed guides and non-divers can feel like they're underwater with virtual reality information centres on land．
5．What is the main idea of the text
A．An underwater museum is under construction．
B．An ancient merchant ship is discovered．
C．Greece is trying to protect its heritage．
D．Divers are interested in Greece．
6．How long has the ship remained off-limits to the public
A．For about 2，000 years．
B．For about 400 years．
C．For about 40 years．
D．For about 20 years．
7．Why do researchers regard it as the most important shipwreck
A．It carried 4，000 vases of valuable wine．
B．It becomes the first underwater museum．
C．It corrected some of our misunderstanding．
D．It is the oldest merchant ship in the world．
8．What can be inferred from the text
A．Some virtual reality equipment is on the ship．
B．All the visitors need to stay underwater to visit．
C．A fire must have broken out on the ancient ship．
D．There is more than one way to visit the museum．

Distinguished guests，
I am Li Hua． On behalf of my school，I'd like to express our warm welcome．It's a great privilege for me to accompany you on the visit to Taicang Harbour．
The harbour witnessed the first voyage of Zheng He，one of China's greatest explorers．A large fleet led by him navigated the blue seas，creating a splendid scene．Altogether，Zheng He made seven voyages to many countries and regions with his ships loaded with china，silk and tea as gifts．These voyages have a far-reaching impact on China and its neighbors，helping develop and strengthen mutual harmonious relations．
May you have an unforgettable experience．
Ⅰ．[语篇解读] 本文是一篇说明文。文章介绍了红海的顶级潜水胜地之一——达哈卜。
1．C [细节理解题。根据第一段“At the foot of Egypt's Sinai mountains，once a small fishing town，Dahab is now one of the Red Sea's top diving resorts，attracting a lot of nature lovers．”可知，Dahab吸引了很多自然爱好者。故选C项。]
2．A [推理判断题。根据第二段“On a normal day，I wake up，make breakfast，go for a free dive，hang out on the beach，take a hike，eat and then sleep．”可推断，她在Dahab的生活是放松的。故选A项。]
3．D [细节理解题。根据第四段“To reduce the traffic here，a local group of divers have created an underwater museum filled with giant statues made of recycled materials．”可知，博物馆有可回收材料制成的雕像。故选D项。]
4．B [写作意图题。根据第一段以及纵观全文可知，本文的目的是介绍达哈卜这个红海的顶级潜水胜地之一，所以本文的目的是介绍旅游景点。故选B项。]
[语篇解读] 本文是一篇说明文。文章介绍了希腊正在筹建的第一家水下博物馆。
5．A [主旨大意题。通读全文，尤其是第一段“Dive into the classical world via the remains of an ancient merchant ship that dates all the way back to 5 BC as Greece is constructing its first underwater museum．”可知，本文主要介绍了希腊正在筹建第一家水下博物馆。故选A项。]
6．C [细节理解题。根据第二段中“Since a fisherman discovered the ship in 1985，it has remained off-limits to the public but now visitors can explore it by sea or by virtual reality．”可知该沉船从1985年与大众隔绝至今，由此可以计算出大约40年。故选C项。]
7．C [细节理解题。根据第三段中“So when it was discovered years ago，it completely changed our understanding of shipbuilding in the ancient world．”可知该发现重要的原因是它完全改变了我们对于远古时代商船建造的错误观点。故选C项。]
8．D [推理判断题。根据文章最后一句“Divers will be able to tour the shipwreck with licensed guides and non-divers can feel like they're underwater with virtual reality information centres on land．”可知参观并非只有水下这一种形式。故选D项。]
