三文魚的一生雅思范文：

話題：The diagram below shows the life cycle of a salmon, from egg to adult fish.

范文

The diagram illustrates the stages in the life of the salmon, from birth to maturity.

It is clear that there are six* main stages as the salmon develops from egg to mature adult. We can also see that salmon spend time in three distinct locations during the cycle, moving from river to estuary to ocean and then back upstream.

Salmon begin their lives in rivers where the adult fish lay and incubate their eggs. After emerging from eggs, the young salmon spend the next stage of their lives being reared in freshwater areas. Then, at some point in their development, the fish swim downstream to river estuaries where rearing continues.

Following the estuary rearing period, the maturing salmon migrate to the ocean, where they eventually become fully grown adults. Finally, the adult fish travel back upstream to spawning areas of rivers; here they reproduce and lay their eggs, and the life cycle begins anew.

雅思寫作范文：英國移民

話題：The chart below shows long-term international migration in UK.

范文

The chart gives information about UK immigration, emigration and net migration between 1999 and 2008.

Both immigration and emigration rates rose over the period shown, but the figures for immigration were significantly higher. Net migration peaked in 2004 and 2007.

In 1999, over 450,000 people came to live in the UK, while the number of people who emigrated stood at just under 300,000. The figure for net migration was around 160,000, and it remained at a similar level until 2003. From 1999 to 2004, the immigration rate rose by nearly 150,000 people, but there was a much smaller rise in emigration. Net migration peaked at almost 250,000 people in 2004.

After 2004, the rate of immigration remained high, but the number of people emigrating fluctuated. Emigration fell suddenly in 2007, before peaking at about 420,000 people in 2008. As a result, the net migration figure rose to around 240,000 in 2007, but fell back to around 160,000 in 2008.

The line graph compares the percentage of people in three countries who used the Internet between 1999 and 2009.

It is clear that the proportion of the population who used the Internet increased in each country over the period shown. Overall, a much larger percentage of Canadians and Americans had access to the Internet in comparison with Mexicans, and Canada experienced the fastest growth in Internet usage.

In 1999, the proportion of people using the Internet in the USA was about 20%. The figures for Canada and Mexico were lower, at about 10% and 5% respectively. In 2005, Internet usage in both the USA and Canada rose to around 70% of the population, while the figure for Mexico reached just over 25%.

By 2009, the percentage of Internet users was highest in Canada. Almost 100% of Canadians used the Internet, compared to about 80% of Americans and only 40% of Mexicans.
