问题 You should spend about 20 minutes on this task.
The graph below compares figures for the production and consumption of energy in the US from 1950 to 2000. It also predicts figures for 2025.
Summarise the information by selecting and reporting the main features, and make comparisons where relevant.
Write at least 150 words.

答案The graph shows changes in the gap between US energy consumption and production since 1950. It also estimates trends up to 2025. Between 1950 and 1970 both production and consumption increased from just over 30 units to about 65, and although consumption was consistently higher, the difference was marginal during this period. However, production grew only gradually over the next 30 years to reach 70 units in 2000. In contrast, growth in consumption was steeper and more fluctuating, reaching 95 units by 2000. Energy imports needed to bridge this gap therefore increased from very little in 1970 to a substantial 25 units in 2000. Projections up to 2025 indicate that this trend is likely to continue, with the gap between production and consumption widening. By 2025 it is expected that consumption will reach 140 units, while production will reach only 90, so more than 30% of energy consumed[50 units]will have to be imported. Overall, the graph indicates that energy production in the US is not keeping up with consumption, so imports will continue to increase.
