In recent years, climate change has had a great impact     1    animals. In 2013, the whole world     2    (shock) by a news photo of a dead polar bear on Norway’s Arctic island of Svalbard. Due to the rise in temperature, the polar bear seemed     3    (die) from lack of food.

According to climate scientists, a key climate process,     4    is called the “greenhouse effect”, includes the “natural” greenhouse effect and the “man-made” green-house effect. The former refers to the fact that heat from the sun     5    (enter) the atmosphere and warms Earth’s surface.

Greenhouse gases in the atmosphere trap some of the heat,     6    (keep) Earth’s climate warm and habitable. However, the latter has become    7    big problem. When people burn fossil fuels, more heat energy is trapped in the atmosphere and causes Earth’s surface temperature to rise    8    (quick).

The evidence shows that the rise in temperature has led to an increase in extreme weather and natural     9    (disaster) worldwide. Climate scientists have warned that this warming trend will become     10    (bad) if we do not take appropriate measures. The severe situation requires people allover the world to pay more attention to it.

Temperatures around the world are rising. Many places     1     (experience) extreme weather events such as extreme heat since the start of the new century.

Scientists have shown all that is going to get even     2     (bad). They looked at cities in the north half of the planet. They     3     (especial) paid attention to those in the US.

According     4     simple geography, the cities near Canada have cool to mild weather. Those near Mexico     5     (be) hotter and more humid. However, things are going to look and feel a lot different in 2080.

The scientists created a weather model     6     (study) the weather changes in 2080. They considered two important points. One was the warming of the planet by 1.5℃ to 3℃ and     7     other was the increasing greenhouse gas levels. Unluckily, what the scientists found was     8     (surprise)! The cities in the north turned into ones in the south—about 500     9     (mile) south. For example, Washington D. C. felt like Greenwood, Mississippi, and Mississippi felt like Mexico.

That’s bad news for people in the US,     10     is also bad for people everywhere because we’re all in the same boat.

There is little doubt that Earth is getting warmer and warmer. In 2013, a lot of people     1     (shock) by a news photo of a dead polar bear     2     appeared to have starved and died. This alarming case showed how the increase in temperature had     3     effect on Earth’s ecology.

Climate scientists often mention a key climate process     4     (call) the “greenhouse effect”, which has two common meanings. Without the “natural” greenhouse effect, Earth could not sustain life. However, the “man-made” greenhouse effect has now become a big problem because more heat energy is trapped in the atmosphere, causing Earth’s surface temperature to rise     5     (quick).

There is strong evidence that the rise in temperature has led to an increase in extreme weather and natural disasters worldwide, not only     6     (cause) serious damage, but also costing human lives. Climate scientists have warned that if we do not take appropriate actions, this warming trend will probably continue and there will be a     7     (high) price to pay.

Governments need to consider making     8     (policy) and taking appropriate actions to reduce greenhouse gas emissions. We as individuals can also reduce our “carbon footprint”. It is our responsibility     9     (seize) every opportunity to educate everyone about global warming, along     10     its causes and impacts.

There is strong and comprehensive evidence that the rise in temperature     1    (lead) to an increase in extreme weather and natural disasters worldwide, causing serious damage, but also costing human lives. Climate scientists have warned that if we do not take appropriate actions, this warming trend will     2    (probable) continue and there will be a higher price     3    (pay). In fact, news reports are frequently broadcast about extreme rainstorms and heatwaves     4    (cause) deaths and economic losses.

Continued greenhouse gas emissions will result     5    further warming and long-lasting changes to the global climate. This requires the attention of people all over the world. Governments need to consider making     6    (policy) and taking appropriate actions and measures to reduce greenhouse gas emissions. We as individuals can also reduce our “carbon footprint” by restricting     7    amount of carbon dioxide our lifestyles produce. It is our responsibility     8    (seize) every opportunity to educate everyone about global warming, along with its causes and     9    (impact), because this is the most serious issue affecting all of us on this planet. So     10    will you do to help?

Solar terms, which     1     (be) also called Jieqi in Chinese, are days marking one of the 24 time buckets or the solar year in traditional Chinese calendar, used to indicate the alternation of seasons and climate changes in ancient China.

As far back as the Spring and Autumn period, there were four solar terms: mid-spring, mid-summer, mid-autumn    2     mid-winter. After continuous improvement, by the Qin and Han dynasties, 24 solar terms have been     3     (full) established.

The Yellow River Basin in Northern China is believed to be the cradle of the solar terms system. China’s 24 solar terms are a knowledge system and     4     (society) practice formed through observations of the sun’s annual motion and cognition of the year’s changes in season, climate and phenology. Ancient Chinese divided the sun’s movement through the sky     5     24 segments, with each segment     6     (equal) one roughly two-week-long “solar term”.     7     (base) on the sun’s position in the zodiac, the 24 solar terms were created by farmers in ancient China     8     (guide) the agricultural affairs and farming activities. They serve as an instruction manual of sorts for farmers, allowing them to know     9     conditions to expect or what agricultural activities to carry out during certain periods of the year.

Solar terms are often called “the     10     (five) great invention” of China after paper making, printing, gunpowder and the compass.

There is little doubt    1    Earth is getting warmer and warmer, which has a bad impact     2    Earth’s ecology. There is strong and comprehensive     3    　(evident) that the rise in temperature has led     4    an increase in extreme weather and     5     (nature) disasters worldwide, not only causing serious damage, but also     6    　(cost) human lives.     7     (continue) greenhouse gas emissions will result     8     further warming and long­lasting changes to the global climate. This requires the attention of people all over the world. Governments need to consider     9     (make) policies and taking appropriate actions and     10    　(measure) to reduce greenhouse gas emissions. We as individuals can also reduce our “carbon footprint”．
