Have you ever heard thunder during a big snowstorm? If so, you’ve experienced an     1    (extreme)rare weather occurrence.

The things necessary for thundersnow are so uncommon     2    it’s reported that only 0.07 percent of snowstorms     3    (link)with thunder. This explains the excited     4    (react)from the witness to a recent thundersnow

Thundersnow-when thunder and lightning occur during a snowstorm-is most likely     5    (happen)during late winter or early spring when a mass of cold air meets warm air near the ground.

Patrick Market from University of Missouri, says that heavy snowfall is common during thundersnow. In a 30-year study of snowstorms     6    (concern)lightning. Market found that there’s an 86 percent chance that at least 6 inches of snow will accumulate within a 70-mile radius(半径)of the lightning. He says     7    (witness)thundersnow is a matter of being in the right place       8    the right time, but even then, you likely won’t see much.

Thundersnow is most common in the Midwest, the Great Lakes and along coasts     9    moisture(水汽) from warm water can easily evaporate(蒸发)into the colder, drier air above. Some of the places that most frequently report the rare weather event     10    (be) Wolf Creek Pass, Colorado; Bozeman, Montana; and the shores of Lake Ontario.

During my recent travels in China, I went from the top to the bottom of the country. I was astonished at     1     different the weather was in different cities.

The weather was     2     (freeze) cold in Harbin, but felt much warmer in Shanghai, Guilin, Qingdao and Yangshuo. Each place has a different feel and allows you     3     (experience) different things.

In Qingdao, we ate seafood, drank beer and even swam in the sea. In Harbin, we wore our warmest jackets and saw the     4     (amaze) ice and snow sculptures (雕塑).

Shanghai reminded me     5     a city in Europe or America. There are lots of Western cafes.

Guilin was a good place to be touring around during Spring Festival. Fireworks     6     (fill) the sky and the streets were busy with happy people. I visited several old buildings and walked around a beautiful lake.

But Yangshuo     7     (be) my favorite place so far. I could not stop taking     8     (photo) of the beautiful mountains and the Lijiang River. I rode a bicycle along the Yulong River in the warm sun. I ate strawberries and drank tea that came from farms in the mountains.

Now, I am back in Beijing. I am looking forward to     9     next trip. I think I     10     (go) to another warm place!.

At the Tube Station, I see the title “Hot! Hot! Hot!” from a free newspaper. Today, the temperature in London is expected     1     (reach) 30 plus degrees! It is going to be awful on the Central Line, with no air conditioning. Going down the stairs and onto the platform is like jumping into a volcano     2     is erupting. I will avoid the feeling by     3     (think) about work. I work in a tall, glass building. One very hot summer, the sun     4     (reflect) off it and melted cars parked below!

Each summer in London seems     5     (hot) than the last. Perhaps it is time to start planning for the future: I will need to learn to swim! I will join a beginner’s swimming class     6     (immediate). Once the tall buildings     7     (flood), I will be able to survive.

Looking through my newspaper, I’m shocked by photos showing that a hurricane in Asia has destroyed a town. Experts say this bad weather has occurred due     8     climate change. Now that it is hard to avoid a disaster on Earth, perhaps I should start considering moving to space... “    9     next station is Bank!” comes the     10     (announce), and it interrupted my thoughts.

A report shows China experienced more heavy rainfalls and high temperatures,     1    (warn) of increasing climate risks. Temperatures in China    2    (increase) faster than the global average over the past few decades, with extreme weather-related     3    (event) becoming more frequent.

Officials said the country was witnessing     4    (high) daytime temperatures — this July was hotter than previous years and the second-hottest since 1961 — while precipitation（降水量） nationwide in July increased by 3.2%    5    (compare) with previous years. The report comes less than a month after     6    (dead) floods in Henan killed over 300 people and affected millions more. During the extreme weather event, the provincial capital of Zhengzhou recorded a year’s worth of rainfall in    7     day.

This year’s floods have resulted     8    economic losses worth 123 billion yuan ($19 billion) in China.     9    , those losses are 22% lower than the average over the same period in the past five years, according a    10    (office) data.
