    Ask people to name the world's tallest peak and anybody with sound general knowledge will name Mount Qomolangma. But quiz them on its exact __and many will be not sure.

In 1975, Chinese surveyors __ that Mount Qomolangma （Mount Everest） was 8848. 13 meters high. As __ improved, satellites, photoelectricity, radars and gravity measurement technologies were __ to get more exact figures. Of course, someone still had to carry __ to what is the world's rooftop.

In 2005, a Chinese team scaled Qomolangma and found that it was not as high as that, as they __ the height to be 8844. 43 meters. Scaling Qomolangma is no __ task. The average air temperature there is -29 degrees Celsius, even four degrees_____ than in Antarctica. The snow there is 4 —5 meters thick and hurricane-like __ blow all the time. Team members were training to __the extreme conditions.

    Many scientists believe our love of sugar may actually be an addiction. When we eat or drink sugary foods, the sugar enters our blood and affects parts of our brain that make us feel good.

1.In this way, it is in fact an addictive drug, one that doctors recommend we all cut down on.

“It seems like every time I study an illness and trace a path to the first cause, I find my way back to sugar,” says scientist Richard Johnson. One-third of adults worldwide have high blood pressure, and up to 347 million have diabetes. Why? “ 2.“ says Johnson.

Our bodies are designed to survive on very little sugar. Early humans often had very little food, so our bodies learned to be very efficient in storing sugar as fat. In this way, we had energy stored for when there was no food. But today, most people have more than enough. 3.

So what is the solution? It’s obvious that we need to eat less sugar. 4.From breakfast cereals to after-dinner desserts, our foods are increasingly filled with it. Some manufacturers even use sugar to replace taste in foods that are advertised as low in fat.

But there are those who are fighting back against sugar. 5.Other schools are growing their own food in gardens, or building facilities like walking tracks so students and others in the community can exercise. The battle has not yet been lost.

A.We take in more energy and fat.

B.Then the good feeling goes away, leaving us wanting more.

C.Our ancestors were used to poor food, clothing and shelter.

D.So the very thing that once saved us, may now be killing us.

E.Sugar, we believe, is one of the reasons, if not the major one.

F.The trouble is, in today's world, it's extremely difficult to avoid.

G.Many schools are replacing sugary desserts with healthier options like fruit.

    Most of the new diseases we humans have faced in the past several decades have come from animals. The more we come into contact with wild animals, the more we risk a so-called disease “spillover” from animals to humans.

“As people move and wildlife move in response to a changing environment, humans and wildlife and animals will come in contact more regularly,” said Jeanne Fair from the Los Alamos National Laboratory in New Mexico. Fair argues that by shifting  animal habitats, climate change will also make the opportunities for disease spillover more frequent. “Everything is sort of shifting and will shift into the future as the environment changes through climate change,” Fair said.

Scientists, including climatologists and epidemiologists on Fair’s team at Los Alamos, are beginning to model how changes to the climate will impact the spread of infectious diseases. It’s early days for this kind of research, but previous studies suggest that extreme weather has already played a role in at least one outbreak. Scientists say drought and deforestation have combined to force bats out of rainforests and into orchards（果园）in Malaysia to find food. Those bats, a common disease reservoir, then passed the Nipah virus through pigs to humans for the first time in the late 1990s.

“We’re going by the past data to really predict what’s going to happen in the future,” Fair said, “And so, anytime you increase that wildlife-human interface, that’s sort of an emerging disease hot spot. And so, that’s just increasing as we go forward.”

Jeffrey Shaman, head of the climate and health program at Columbia University’s public health school, argues we don’t yet know whether climate change will cause a net increase in infectious disease rates globally. For example, mosquitoes carry disease that affects millions of people across the world every year. As their habitats expand in some parts of the world, they might contract diseases elsewhere. Shaman says what we know for certain about climate change is that it will make it harder to predict where disease outbreaks will pop up.

1.How does climate change affect the spread of disease according to Fair?

A.By breaking animals’ habits.

B.By increasing animals’ varieties.

C.By promoting animals’ breeding.

D.By changing animals’ living environment.

2.What is the example of bats for in paragraph 3?

A.Explaining the influence of Nipah virus.

B.Proving the harm of bats to human beings.

C.Showing the effects of climate change on disease.

D.Presenting scientists’ early study about the cause of disease.

3.What can we infer from Fair’s words in paragraph 4?

A.Humans should give up studying animals.

B.Past data can solve the problems in the future.

C.Disease hot spots will disappear if animals die out.

D.Frequent contact with animals can cause disease outbreaks.

4.What could be the best title for the text?

A.Climate Change and Disease Spillover

B.Animals’ Interaction with Humans

C.Scientists’ Prediction for Disease Outbreaks

D.Early Studies about Extreme Weather

    A storm hit Houston, Texas, on Tuesday. It brought heavy rains and rising flood-waters. By Tuesday night, some parts of the city had received 10 inches of rain. Police and firefighters helped people move to safe places. They also saved people from cars and buses that were stuck on roads.

Certain areas around Houston were hit really hard. In just four hours, more than seven inches of rain fell in Sugar Land in the southwest of Houston. Cars could not pass through any of the areas main roadways. On Twitter, Sugar Land city officials asked people to get to high ground.

Tuesday’s rain hit parts of Texas that Hurricane Harvey had already damaged almost two years ago. Hurricane Harvey in August, 2017 was the second most costly hurricane in US history. It caused $125 billion worth of damage in Texas. In the Houston area, 36 people died and about 150, 000 homes were flooded.

A spokesman for the Harris County Office of Homeland Security and Emergency Management spoke with the Houston Chronicle. The spokesman said that this week’s rain is “not in any way a Harvey-level event.”

But the worst may not be over yet. People will have a break from the heavy rain on Wednesday. According to the National Weather Service, the Texas Gulf Coast will continue to experience heavy rain later in the week. "Today should be our quietest over the next few days for rainfall,” said Don Oettinger, a National Weather Service meteorologist (气象学家).

Houston Fire Chief Samuel Peia warned, “As there is too much water on the ground, these are perfect conditions for flash floods, so we hope people are careful of what they’re doing and encourage them to stay home. There’s no sense in putting yourself, firefighters or anybody in danger needlessly.”

1.What are Paragraphs 1 and 2 mainly about?

A.Flood damage in Houston. B.Flood prevention in Houston.

C.Heavy floods hitting Houston. D.People fighting floods in Houston.

2.What do we know about Hurricane Harvey?

A.It caused no deaths or injuries. B.It did a lot of damage to Texas.

C.It was less serious than this week’s rain. D.It was the biggest hurricane on record.

3.What can we learn from the weather report of the National Weather Service?

A.Fine days are coming. B.It will rain a little non-stop.

C.A hurricane is unavoidable. D.Floods will continue.

4.What did Samuel suggest local people do?

A.Stay indoors. B.Join firefighters.
