It is     1    (common) known that the emission (排放) of carbon dioxide and other greenhouse gases causes great effect on our planet. To control climate change, great efforts     2     (make) across the world in the past few decades. In 1978, China began     3     national-level forestation project -the Three North Shelterbelt Forest Program, also     4     (know) as the “Great Green Wall”. The program has seen trees planted in 13 provinces and autonomous regions of northern China to act     5     windbreaks (防风林). The Kubuqi Desert in Inner Mongolia has also set a good example to those     6    (struggle) against desertification (沙漠化). Now about 33% of the Kubugi Desert is covered with trees and bushes.

In September, China set new goals     7     (deal) with the problem, aiming to have carbon dioxide emissions peak before 2030 and achieve carbon neutrality (碳中和) before 2060. Carbon neutrality     8     (refer) to achieving zero carbon dioxide emissions. If China’s goal is achieved, it will lower     9     (globe) warming by around 0. 2 to 0. 3℃ alone, according to Climate Action Tracker (CAT). It is the biggest single reduction     10    has been estimated by CAT.

We hear about climate change pretty much every day now. Scientists have just announced that July was the hottest month ever     1     (record). The scientists are from the National Oceanic and Atmospheric Administration (NOAA) in the USA. A spokesperson from NOAA said, “July is     2     (typical) the world’s warmest month of the year, but July 2021 beat     3     (it) as the hottest July and hottest month ever.” NOAA said Earth’s land and ocean surface temperature in July increased     4    0.93 degree Celsius,compared to the 20th-century average of 15.8 degrees Celsius. The Northern Hemisphere was 1.54 degrees Celsius hotter than average.

The NOAA spokesperson said this new record was     5     (worry). He said, “In this case, first place is the worst place to be.” The announcement from NOAA comes a week after a 4,000-page report on climate change from the United Nations. It clearly     6     (state) that humans had affected the climate. It wrote, “It is clear     7     human influence has warned the atmosphere, ocean and land.”     8     total of 234 scientists from 66 countries worked on the report. It warns that extreme weather     9     (continue) to get worse. It says every region will experience multiple     10    （change) in weather, like sweltering heat and flooding.

One day at The Dubai Mall, a workmate warned that a sandstorm was going on and suggested not going out. I didn't know    1     a sandstorm looked like and I told him I wanted to go out just to see it for myself. I received an    2     (astonish) look because he thought I was crazy to even want to see a sandstorm. I decided to go to the bus stop to ride a bus that would take me home. Another workmate joined me as he    3     (head) towards the same street as I was. We stepped    4     The Dubai Mall with our faces    5     (cover) in order to protect ourselves from the sandstorm.

On the way, the wind became much    6     (strong), which covered the city in a thick, brown-yellow dust. I could hardly keep my eyes open. It was really dangerous and frightening because there were so many cars on the road and it was already dark. At that moment, I would rather I    7     (not go) out.

    8     (fortune), the storm stopped afterwards. This was the first time I    9     (be) in a sandstorm in Dubai and I don’t ever want to be in    10     again.
