Measuring Qomolangma
In 1856, a British survey team measured the height of Qomolangma, also known as Mount Everest in the
West. While this initial result showed that Qomolangma reached a height of 8,840 meters above sea level, the
exact measurement of the world’s highest mountain has never been settled.
In 1955, the figure was adjusted by an Indian survey team to 8,848 meters, and later to 8,850 meters
according to a US team in 1999. And in 2005, a Chinese team calculated a height of 8,844 meters, but that result
wasn’t widely accepted either.
On May 6, a 30-member Chinese survey team set out to reach the peak of Qomolangma, equipped with the
latest technology – including a Global Navigation Satellite System receiver and a radar to measure the mountain’s
snow cap – and is determined to settle the dispute.
But measuring Qomolangma is no easy task. The average air temperature there is -29 C – four degrees lower
than in Antarctica – and hurricane-like winds blow all the time.
According to Li Guopeng, leader of the No 1 Geodetic Survey Team of China’s Ministry of Natural
Resources, despite advanced technologies we now have—the likes of robots and drones—there is no guarantee
that they can operate smoothly under extreme conditions, which is why sending human experts to the peak is still
necessary to ensure a precise reading.
But does the difference of a few meters really matter when it comes to a gigantic mountain?
The truth is that measuring the height of Qomolangma is much more than just getting that one particular
number. Located at the point where the Eurasian plate meets the Indian plate, Mount Qomolangma emerged from
an ocean 38 million years ago as a result of the two plates colliding, which makes it the perfect window for
observing crustal movements. Changes to the peak’s height can indicate whether the two plates are headingtoward or away from each other.
The survey team will also get firsthand information about the condition of the snow and other natural
materials at the top, which could be an indicator of climate change on the Tibet-Qinghai Plateau.
It might be true that settling a dispute was the initial driving force for continued exploration, but the good
thing is that we always end up discovering so much more.

Geology rocks!
It’s not easy keeping track of Sam Mukasa, a University of Michigan geologist.
Sam could be anywhere in the world looking at rocks or poking around volcanoes! He has been on
expedition to Antarctica nine times. We caught Sam’s recent lecture at the University of Michigan’s Exhibit
Museum of Natural History in the US.
Born in Kenya, Africa, of Ugandan parents, Sam told us his own fascinating story.
“How did someone born at the equator end up working in Antarctica?” he said, chuckling. “When I was
about 8, a very adventurous uncle took me up a very small mountain and I was hooked for life. Some seven years
later, I found myself on top of Mt. Kilimanjaro and some eight years later, I found myself doing work on a
doctorate in the Andes.”
But Peru became dangerous because of political reasons. So Sam left and made his way first to Chile, then to
Tierra del Fuego at the tip of Argentina.“Then I worked my way to South Georgia Island, and by this time I could actually start smelling Antarctica.
So it was only a matter of time before I started working in Antarctica.”
Sam’s knowledge of Antarctica is immense. His lecture was packed with surprises. How many people know
that 146 freshwater lakes lurk beneath the frozen continent? Or that one, Lake Vostok, is about the same length as
Lake Ontario?
“If it were at the surface, it would be recognized as the seventh largest lake in the world,” said Sam.
And get this: A volcano also lurks beneath Antarctica!
“We didn’t even know about it until a couple of years ago,” said Sam. “It erupted 2,000 years ago, spreading
ash over a very large area. In the future, there could be another eruption that could have a devastating effect on the
ice.”
Antarctica was only part of Sam’s studies. We will follow Sam’s work on other fields in the future. Stay
tuned for more interesting stories.
6．Sam has explored Antarctica ________ times.
A．seven B．eight C．nine D．ten
7．Sam was born in ________.
A．Britain B．Africa C．Antarctica D．Argentina
8．Sam climbed a mountain with his uncle at the age of ________.
A．eight B．nine C．fifteen D．twenty-three
9．There are 146________ beneath the frozen continent in Antarctica.
A．salt water lakes B．freshwater lakes C．rivers D．artificial lakes
10．Which of the following is true?
A．Sam knows much about Antarctica.
B．Sam is sure that there will be another eruption in Antarctica.
C．There is no volcano beneath Antarctica.
D．Sam only works in Antarctica.

Exploding mountains
Boom! You hear a distant explosion. Then suddenly, the air is filled with thick smoke and dust. In the
distance, you can see red-hot lava flowing down the side of a hill. What is going on?
You just saw a volcanic eruption. That’s when a volcano, which is basically a hole in Earth’s surface, sends
out hot ash, gas, and rocks into the air.
These eruptions can be quite dangerous. They can destroy houses and burn or choke people to death. Avolcano in New Zealand called White Island recently erupted, killing 16 people and injuring many others.
How do volcanoes form? As you may know, Earth’s surface is actually broken up into 17 parts, which are
called tectonic plates. These plates move around sometimes. When they separate from or crash into each other,
they usually form valleys or mountains. But sometimes, a volcano forms instead.
Volcanoes can be either dormant or active. If a volcano is dormant, it is “asleep”. There is little to no risk that
it will erupt. But if it’s active, it is “awake”. It could erupt at almost any time!
White Island is an active volcano. It is located along the “Ring of Fire”, which refers to the chain of
volcanoes that circles the Pacific Ocean.
The outside of the volcano has many cracks in it that allow water to get inside. Once water goes in, it is
heated by the super-hot lava inside and turns into steam. But then, the steam becomes trapped. It has nowhere to
go. This causes the volcano to violently erupt, sending out clouds of superheated steam, hot ash and rocks. Many
eruptions occur in this way.
11．The air is filled with________ after a volcanic eruption.
A．small stones and dust B．thick smoke and dust
C．thick smoke and water D．dust and water
12．The eruption of White Island killed________ people.
A．16 B．17 C．18 D．19
13．Earth’s surface is broken up into________ parts.
A．7 B．8 C．16 D．17
14．________ could erupt at almost any time.
A．The Island B．The Dormant volcano
C．The Active volcano D．The Mountain
15．Water will become _______ after it gets in the volcano.
A．steam B．rocks C．ice D．lava

（23-24八年级上·安徽芜湖·期末）Swifts (雨燕) live mostly in the air. These small birds are among the
fastest animals on Earth. In fact, swifts can go two or three days without touching the ground! To get used to life
in the sky, swifts use their speed and the saliva (唾液) in their mouths.
Swifts can fly faster than 100 miles per hour. That’s because their wings are like boomerangs (回力镖). Thisshape of the wings helps them to fly much faster. They can also move one wing faster than the other, which allows
them to make sharp turns without slowing down. Making fast, sharp turns helps swifts catch flying bugs to eat.
The saliva helps swifts catch bugs to feed their young. It is sticky, like glue. Swifts often fly into clouds of
bugs such as mosquitoes and open their wide mouths to catch as many insects as they can. The bird collects as
many insects as they can. The bird collects insects in its mouth gradually (逐渐地) and holds the insects in a
sticky ball of saliva. One food ball can contain nearly 1,000 bugs.
Swifts also use their saliva as glue to build their nests. The birds catch feathers in the air and stick the
feathers together to build a strong nest. Swifts’ short feet are not good for walking or standing on land for long.
But their sharp claws allow them to stick to rocks and walls so they can take a short rest before returning to their
lives in the sky.
25．The second paragraph mainly talks about ________.
A．how fast swifts can fly B．how swifts turn around in the sky
C．why swifts make sharp turns D．why swifts can fly and turn so fast
26．What does the underlined word “It” refer to in Paragraph 3?
A．The saliva. B．The air. C．The shape. D．The speed.
27．Which of the following is True about swifts?
A．They don’t usually live on land because of wings.
B．They can fly for a long time because of their small bodies.
C．They can’t walk for a long time because of their short feet.
D．They can catch nearly 1,000 bugs in one go with the saliva.
28．Which of the following best shows the structure of the passage?
A． B． C． D．

（23-24八年级上·广西来宾·期末）There are about 5, 000 different kinds of ladybugs (瓢虫) in the world.
They come in many different colors. Their bright colors warn other animals or insects not to eat them. Ladybugs
taste bad. A bird or a frog that eats a ladybug will remember the bright colors and it will not eat another ladybug
with the same colors again. When ladybugs are in danger, they will give out a fluid (液体) that tastes terrible.
In many cultures, the ladybug is considered to be a symbol of good luck. Most ladybugs are kind to humans.
They eat other insects which destroy crops. One ladybug can eat up to 5, 000 insects in its lifetime.
Ladybugs have six short legs. They live in many different places, including green lands, forests, cities, thecountryside and along rivers. Different ladybugs have different spots (点) . Some of them don’t have spots at all.
The most common kind in North America is the 7-spotted ladybug. The 7-spotted ladybugs are the most active
from spring to autumn. When the weather turns cold, they look for a warm place to sleep, such as under stones or
in houses.

（23-24八年级上·山东济南·期末）When a baby elephant is born, it stands quickly on its feet. It drinks
milk from its mother for a few years. The mother elephant is very important to a baby elephant. 34
Elephants travel a lot. Sometimes they have to cross rivers. The water might run too quickly and wash a baby
elephant down a river. Or it can fall into a hole. When a baby elephant loses its mother, it becomes an orphan.
Sometimes a baby elephant becomes an orphan because its mother is killed.
In the wild (野外), a baby elephant can’t live without its mother. Some people, called keepers, look after the
orphan elephants in a park. 35 Then, the keepers send the elephants back to the wild.
In the wild, a baby elephant will stay under its mother to keep cool from the sun. 36 The keepers
need to teach a baby elephant how to feed. To make it more relaxed, they always try many ways.
37 Some people killed Dika’s family, and he ran away. The keepers took Dika to the park. The
keeper looked after him very well, but he cried for his mother. It was a long time before Dika was happy again.
Dika was ten years old before he could live in the wild again. Many years later, he came back to the park. He had
