Task 1（小作文）

题目解释：折线图，比较三个国家在六年里留学生人数的变化。

要点分析：此次考题难度较小，是一个很常见的表现几个变量在一段时间内变化趋势的动态图表。写作时需要注意如下几点：
1.     尝试发现整幅图最明显的特征：从整体趋势看，三个国家留学生人数在整段时间区间的开始和结束都没有太大变化（The general trend shows that the number of overseas students in all the three countries remained constant throughout the given period.）;从数值大小来看，美国留学生人数一直最多而澳大利亚一直最少（The USA accepted the largest number of overseas students, while Australian schools gave offer to the fewest students.）

2．描述不同的变化区间时注意句型的变化。
1）分词：Starting from 50,000 in 2002, the number of overseas students in the USA experienced a decline in the following years.
2)状语从句：The number of overseas students in Australia was about 8,000 in 2002. Then it increased stably until 2004, when it reached a peak at 10,000, and started a three-year leveling-off.
3)插入语：The U.K., bearing the medium number of overseas students, saw the number fluctuating between 30,000 and 25,000 during the given period.
