九、阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。
China has so many beautiful places. 1 You may find the answer in the new documentary (纪录片).
Its name is Aerial China (《航拍中国》). CCTV made it. There are already six episodes (剧集). 2 The
first six episodes are about Hainan, Shaanxi, Xinjiang, Heilongjiang, Jiangxi and Shanghai.
In the show, you can see great mountains, big grass lands, colorful blossoms and old city walls. “Every frame
of this show would make a great desktop wall paper,” wrote the Huashang Morning Post. 3 It’s the world’s
biggest ocean blue hole. If you see it from above, it’s a circle of different shades (色度) of blue. This gives it the
name of “the eye of the South China Sea”.In the show, the Beiji village in Heilongjiang looks like a place in fairy tales (童话). 4
People there build small low houses with pine logs (松木). In winter, white snow is all over the roofs. When
you see it from the air, it looks even smaller, like a toy.
In the next five to six years, the Aerial China series will show all 34 province-level (省级) places in the
country. 5
A．But what do they look like from the air (空中)?
B．Each episode shows the beauty of a different place.
C．Every one of you may see your hometown in the show!
D．The village is in the northernmost (最北的) part of China.
E．Sansha Yongle Blue Hole in the South China Sea is a really surprising place.
十、阅读理解。
（A)
The Xisha Islands are in the northwest part of the South China Sea. They are beautiful places with nice views
and many resources (资源). This is how our primary school textbook describes them.
Many Chinese people know about the South China Sea and the Xisha Islands, but only a few have been there.
These islands are far away and have a weak ecosystem (生态环境). Because of this, most activities there are just
fishing, protecting the environment, and doing scientific study. Visitors are mainly government workers,
fishermen’s relatives, and media (媒体) members.
In 2007, the Chinese government set up Sansha City on Xisha’s Yongxing Island. I once visited Yongle
Islands, part of Sansha. I thought the fishermen’s homes would be simple, but they were very comfortable. The
island had a vegetable garden, and green vegetables were seen on the local tables. I stayed in a hotel with a
playground downstairs. After dinner, everyone got together to play games. Later, I walked along the island’s paths,
enjoying the sea view and peaceful moment.
Fishermen told me they used traditional ways to fish. They knew exactly which fish could be caught because
of their different sizes. As for smaller fish, fishermen released them back into the sea.
One thing that I never forgot was an outdoor movie called Island Keeper. It was about a couple who guarded
(保卫) the island for 32 years. Many fishermen were moved to tears. One fisherman said as life on the island
improved, his family loved to stay on the island during the fishing season. He also drove a passenger boat, so he
made more money even when he was not fishing.
The careful management (管理) of the Xisha Islands limits (限制) tourism but gives job opportunities (机会)
to local fishermen.
1．What does the word “them” in the first paragraph refer to?
A．nice views B．the Xisha Islands C．many resources D．the South China Sea
2．What causes only a few people to visit the Xisha Islands?
①The islands are far away. ②Not many people know the islands.
③ The ecosystem there is weak. ④ The islands are used for scientific study.
A．①② B．③④ C．①③ D．②④3．What does the underlined word “released” in Paragraph 4 probably mean?
A．looked for B．cut…down C．took care of D．let...go
4．What can we infer from the text now?
A．Fishermen catch fish in modern ways.
B．Fishermen enjoy their life on the islands.
C．More and more visitors come to Xisha Islands now.
D．The living conditions of fishermen are poor and simple.
5．Which of the following best shows the structure of the text? (1= Paragraph 1）
A． B． C． D．
(B)
Do you know what the world’s highest waterfall is? You may say that it is Niagara Falls. Niagara Falls is really
beautiful, but as for height, the most fantastic one in the world is Angel Falls. It is deep in the jungles (丛林) of
Venezuela and stands about 979 meters tall-about 15 times higher than Niagara Falls.
Few people have ever seen Angel Falls. It’s very hard to get there. If you go there on foot, you have to travel
for weeks through thick jungles filled with wild animals and dangerous plants. If you go by plane from Caracas, a
city on the southern coast, it will take about four hours.
One interesting thing about Angel Falls is how people found them. They named them after an American pilot.
His name was Jimmy Angel. In 1937, his plane crashed (坠毁) near the top of the falls while he was searching for
gold. That’s how he found them. Luckily, Jimmy Angel and his passengers survived (幸存) the crash.
Angel Falls drops nearly a kilometer from a table-top mountain. The water seems to be dropping straight out
of the clouds. The height of the falls is very great. By the time the water reaches the ground, it has already turned
into fog. During the dry season, there might not be much water, but in the rainy season, the falls are amazing to see.
Many people consider Angel Falls to be nature’s most wonderful creation.
根据短文内容，判断下列句子正 (T)、(F)。
1．Niagara Falls is deep in the jungles of Venezuela.
2．Many people have ever seen Angel Falls, the most fantastic one in the world.
3．If you want to visit Angel Falls, you’ll spend four hours getting there on foot.
4．An American pilot found Angel Falls while he was looking for gold.5．When the water reaches the ground, it has turned into ice.
十一、任务型阅读。
阅读下面的材料，根据内容回答问题。
Qomolangma is the highest mountain in the world, which is 8,848. 86 metres high. It’s called “the Roof of the
World”. But Mount Kilimanjaro is the highest mountain in Africa. It is one of the most beautiful places on the earth
which is 5,895 metres above sea level, so it is often called “the Roof of Africa”.
Climb lovers’ dream place—Mount Kilimanjaro
It is one of the world’s highest “walkable” mountains. People can climb the mountain all year round, but many
people will choose to climb during the mountain’s two “dry” seasons, January to March and June to October. If
they want to reach the top of it, they can climb in the rainy season too, but the weather condition may not be good
and it may be difficult to achieve.
The first recorded climb of Mount Kilimanjaro
It’s believed that the first people known to have reached the top of the mountain were Hans Meyer and Ludwig
Purtscheller. Through hard work, they successfully reached the top of the mountain on 6th October, 1889.
The beautiful snow cap of Mount Kilimanjaro
Even though it is hot there, the top of the mountain is covered with ice and snow the whole year. There are
many famous stories of the snow cap of Mount Kilimanjaro. It formed about 11,000 years ago, but a research said
that it might disappear.
One of the reasons for its possible disappearance is global warming. The high temperature is making the ice on
Mount Kilimanjaro melt. The beautiful snow cap of Kilimanjaro is disappearing quickly.
1.How high is Mount Kilimanjaro?
____________________________________________________________.
2.How long has the snow cap on Mount Kilimanjaro formed?

The Hottest Place on Earth
Part 1: Read and Explore
Where is the hottest place on Earth? You might think it is in Africa, but it is not. The hottest place is actually
Death Valley in California, USA.
Death Valley is a desert. In 1913, the temperature there reached 56.7°C. That is the highest temperature ever
recorded on Earth. In summer, the ground can be as hot as 93°C. You could fry an egg on the rocks!
The name “Death Valley” sounds scary. In the past, some travelers died there because they did not have
enough water. But today, people still visit this place. Why? Because it is also very beautiful. The sand dunes,
colorful rocks, and bright blue sky make it look like another planet.
At night, the temperature drops quickly. It can go from 50°C in the day to 20°C at night. Some animals come
out only at night when it is cooler. The coyote and the desert fox are two of them.
Death Valley is getting even hotter because of climate change. Scientists say summers there will be hotter and
longer in the future. But for now, it is still the hottest place on Earth — and one of the most amazing.
