The graph below shows the average carbon dioxide (CO2) emissions per person in the United Kingdom, Sweden, Italy and Portugal between 1967 and 2007.

Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

The line graph gives information about the amount of CO2 that was produced by one person in five European countries, namely the UK, Sweden, Italy and Portugal over 40 years from 1967 to 2007.
Overall, the average carbon dioxide emissions per person of four countries fluctuated throughout the period. It was notable that the UK had the largest CO2 emissions while the opposite was true for Portugal which was the lowest all the time.
At a glance, the carbon dioxide emissions of the UK dominated for a long time. At the beginning, there were approximately 11 metric tonnes of CO2 which were brought out by Britain yearly. In the next 10 years, it experienced a slight drop before continuing to go down steadily the rest time. In 2007, this figure was only a little under 9 metric tonnes. Similarly, Sweden was also one of the countries that had a large average CO2 emissions in Europe with just over 8 tonnes initially. It had a sharp increase to over 10 tonnes before decreasing by 3 tonnes in 1987. From that time to 2007, it had reduced gradually from 7 tonnes to just over 5 tonnes for 2 decades.
On the other hand, Italy and Portugal were two countries that had a low CO2 emissions per person per year. They also had similar changes by the time. Originally, while the Italian produced about 4 tonnes of CO2, this figure of Portugal accounted for only about 1.5 tonnes. The year 1977 saw a significant increase of CO2 emissions of Italy to over 6 tonnes. After that, it grew marginally from 7 tonnes to just under 8 tonnes until the year of 1997 then remained stable up to now. Besides, Portugal had also climbed gradually from around 1.5 tonnes in 1967 to 3.5 tonnes in 1987. In the next 10 years, they continued to go up but faster than last period by 2 tonnes in 1997 before stabilizing at that point all the rest time.

Gợi ý nâng cấp từ vựng

1. "The line graph gives information" -> "The line graph presents data"
   Explanation: "Presents data" is more precise and formal than "gives information," which is somewhat vague and informal for academic writing.

2. "namely the UK, Sweden, Italy and Portugal" -> "namely the United Kingdom, Sweden, Italy, and Portugal"
   Explanation: Using "United Kingdom" instead of "UK" and adding commas after "Italy" for clarity and consistency in formal writing.

3. "it was notable that" -> "it is notable that"
   Explanation: Changing "was" to "is" corrects the tense to match the context of the graph, which is about a historical trend.

4. "the largest CO2 emissions" -> "the highest levels of CO2 emissions"
   Explanation: "Highest levels of" is more precise and formal than "largest," which can be ambiguous in this context.

5. "the opposite was true for Portugal" -> "the converse was true for Portugal"
   Explanation: "Converse" is more formal and academically appropriate than "opposite" in this context.

6. "At a glance" -> "Upon initial inspection"
   Explanation: "Upon initial inspection" is a more formal phrase suitable for academic writing than the colloquial "At a glance."

7. "brought out" -> "released"
   Explanation: "Released" is more precise and formal than "brought out" in the context of emissions.

8. "it experienced a slight drop before continuing to go down steadily the rest time" -> "it experienced a slight decline before steadily decreasing thereafter"
   Explanation: "Decline" and "decreasing thereafter" are more precise and formal than "drop" and "going down steadily the rest time," which is awkward and informal.

9. "Similarly, Sweden was also one of the countries" -> "Similarly, Sweden was another country"
   Explanation: "Another country" is more concise and formal than "one of the countries."

10. "just over 8 tonnes" -> "approximately 8 tonnes"
    Explanation: "Approximately" is more precise and formal than "just over," which is somewhat informal.

11. "it had reduced gradually" -> "it gradually decreased"
    Explanation: "Decreased" is a more direct and formal verb choice than "reduced," which can be vague.

12. "for 2 decades" -> "over two decades"
    Explanation: "Over two decades" is more formal and precise than "for 2 decades."

13. "Originally, while the Italian produced" -> "Initially, the Italian production"
    Explanation: "Initially" is more formal than "originally," and "the Italian production" corrects the grammatical error in the original phrase.

14. "this figure of Portugal accounted for only about 1.5 tonnes" -> "Portugal’s emissions accounted for approximately 1.5 tonnes"
    Explanation: "Portugal’s emissions" is more specific and formal than "this figure of Portugal," and "approximately" is more suitable than "about" in academic writing.

15. "The year 1977 saw a significant increase of CO2 emissions" -> "In 1977, there was a significant increase in CO2 emissions"
    Explanation: "In 1977, there was" is more formal and avoids the awkward construction of "saw a significant increase of."

16. "it grew marginally" -> "it increased marginally"
    Explanation: "Increased" is more direct and formal than "grew," which can be vague in this context.

17. "until the year of 1997 then remained stable up to now" -> "until 1997, after which it remained stable"
    Explanation: "Until 1997, after which it remained stable" is more concise and formal, avoiding the awkward phrasing of the original sentence.
