We know that the levels of carbon dioxide has
increased greatly over last 100 to 150 years. It
was a scientist was called Charles Keeling, who made accurate measurements of the amount of carbon dioxide in the atmosphere from 1957 to 1997. He found that from these years the carbon
dioxide in the atmosphere went down from
around 315 parts to around 370 parts per million.
All scientist accept this data. He also agree
that it is the burning of more and more
fossil fuels that have resulted in this increase
in carbon dioxide. However, the attitude of scientists for this rise is completely difference.
1. has→ have 因主语levels为复数形式,故用have。
2. 在last前加the 指在“最近多少年里”习惯上说in /over the last…years,且与完成时连用。
3. 去掉called前的was 过去分词called作后置定语。
4. that后的from→ between 指代前面的from 1957 to 1997。表示“在……期间”,用介词between。
5. down→ up 根据下文“from around 315 parts to around 370 parts per million”可知应该是上升(go up),而非下降(go down)。
6. scientist→ scientists “所有的科学家”,肯定不止一个,所以用复数。
7. He→ They 指代前句的scientists,用复数形式。
8. have→ has 强调句式,强调主语the burning of more and more fossil fuels,根据主谓一致,与the burning一致应为单数,故改用has。
9. for→ to/towards 表示“对……的态度”,为the attitude to/towards…。
10. difference→ different 作表语,应用形容词形式。
a quantity of/quantities of后既可接复数可数名词,也可接不可数名词,作主语时,谓语动词的单复数与quantity的单复数一致。
1. quantities of(=a large quantity of) 许多;
