## 一、选择/判断题答案

1. **错** — Overview 不罗列具体数据，只概括整体趋势与主要特征；数据细节放在正文段展开。

2. **C** — Overview 放在开头（紧跟 introduction 之后）或结尾均可，但必须位置清晰、一眼可辨，让考官能立刻找到。

3. **B** — B 句概括了整体趋势（steady upward）与对比（whereas costs fluctuated sharply），是标准 overview；A 是具体数据描述，C 只是复述题目，都不符合 overview 的要求。

4. **错** — 机械罗列每一个数据点会被视为缺乏"selecting and reporting main features"的能力，反而扣 Task Achievement 分；只挑 3–4 个关键特征展开即可。

## 二、填空/简答答案

5. 整体趋势 / 主要特征（overall trend / main features，写"大方向""整体走势"均可）

6. 参考答案（任答 3 类即可）：起点与终点数值；最高值 / 最低值（峰值）；最明显的变化幅度（涨/跌最陡的一段）；交叉点或转折点；两者之间最大的差距。

## 三、Task 1 范文（地铁 vs 公交，约 170 词）

The line graph illustrates how the number of passengers using two types of public transport in a city — the subway and the bus — changed over a thirty-year period from 1990 to 2020.

Overall, subway ridership experienced a steady upward trend throughout the period, whereas bus usage rose initially but then fell sharply, with the two figures crossing around 2005.

In 1990, the bus was by far the more popular mode of transport, carrying 5 million passengers compared with only 2 million for the subway. Bus usage continued to grow over the next fifteen years, reaching a peak of 6 million in 2005. From that point onward, however, the number of bus passengers declined considerably, falling to 3 million by 2020.

By contrast, subway ridership climbed consistently across the entire period. It grew from 2 million in 1990 to 8 million in 2020, overtaking the bus around 2005 when both carried roughly equal numbers of passengers. By the end of the period, the subway had become the city's dominant form of public transport.

### 范文要点拆解
- **Overview 独立成段**：第二段一句话讲清趋势（upward）＋对比（whereas）＋交叉点（crossing 2005），零具体数字。
- **数据精选**：只挑了起点、峰值、终点、交叉点这 4 类关键特征，其余数字一概不写。
- **连接词**：whereas / however / by contrast / overall，让对比关系一目了然。
- **时态**：全篇过去时（图表描述的是过去 30 年），保持一致。
