高分范文片段解析
The line graph below shows changes in global average temperatures from 1900 to 2020.
范文节选：
The graph illustrates fluctuations in global temperatures over a 120-year period. Initially, the average temperature remained stable at around 13.5°C until 1920. From this point onwards, a gradual increase occurred, reaching 14°C by 1950. The most dramatic surge took place between 1980 and 2020, when temperatures rose sharply to 15°C. Notably, the rate of increase accelerated after 2000, with an average annual rise of 0.1°C.
