    开头段

    The line graph illustrates changes in the proportion of people from five age groups who went to museums at least once a month between1980 and 2010.

    概述段

    Overall, all age groups saw an increase in museum visits over the period, except for those aged 46-65. The most significant growth was observed among the youngest age group

    思路要点：
    - 除了46-65之外，其他年龄段的人数比例都呈现上升趋势
    - 18-25岁人数比例涨幅最大

    Body paragraph 1

    Initially, 30% of people in the age bracket of 26-to-45 visited museums, the highest proportion among all groups. This figure rose steadily to 40% by 1988, before falling slightly by 5% over the next eight years. However, the final 14 years saw a sharp increase to 55%. Similarly,the percentage of young people(18-25) soared from only 15% in 1980 to almost 70% in 2010, overtaking the figure for those aged 26-45 in 1996.

    思路要点：18-25(蓝色)、26-45(橙色)
    - 橙色：1980年四个年龄组里最高(30%)→随后显著上升到1988年的40%→1996年小幅度下降了5%→2010年显著上升到55%
    - 蓝色：1980的15%急剧上升到2010的70%。其中在1996年超过橙色

    Body paragraph 2

    In contrast, the proportion of museum visitors over 46 years old remained relatively low throughout the period. Specifically,  a marginal rise from 25% in 1980 to a peak of 30% in 1988 could be found in the 46-65-year-olds, after which there was a remarkable drop by 15% in the final year. Likewise, the figure for the oldest age group tripled to 30% in the beginning 16 years, followed by a modest drop to 10% in 2004. Afterwards, this figure surpassed the percentage of people aged 46 to 65 and doubled in 2010.

    思路要点：46-65(黄色)、65+(绿色)
    - 其余两个年龄组数据较小
    - 黄色：1980年25%小幅度上升到1988年峰值30%→到2010年显著下降了15%
    - 绿色：1980年到1996年上升了3倍达到30%→2004年小幅度下降到10%→随后在超过黄色数据，于2010年翻倍，
