线图属于动态图,在考试中出现频率较高,线图的描述方法可以应用到其他动态图表。然而同学们在备考中往往只记一些基本的单词和句式,不能很好地组织内容和语言来取得较好的分数,以下将讲到线图备考常见问题。
一 审题失误
以上是一个多线图,我们先来看一个同学文章段落中间的描述:
Throughout the whole period, beef and lamb declined sharply from 220 and 150 grams to approximately 100 grams and 55 grams respectively.
我们从小标题看到,此题的对象并非肉类本身,应该是这些肉类的消耗,所以应该改为the consumption of beef and lamb。
二 词汇运用有误
例如 The percentage of people living in poverty in this area raised dramatically to 50% in 1998.
此句话中raise是及物动词,后面直接跟宾语,rise 是不及物动词, 后面不能直接跟名词,可以加介词,根据时态本句话raised应改为 rose。
三 语法错误较多
例如:The number of workers employed in this private company were 85 in 1990.
the number of 后加可数名词复数,谓语动词和系动词应该用单数,a number of 加可数名词复数,谓语动词和系动词用复数,所以本句were应该改为 was.
我们再来看一个例子:
a significant growth was shown in the percentage of students enrolled in famous universities throughout the whole period, reaching 60% in 2005.
此句reaching部分为分词作状语,逻辑主语应和主句主语一致,但是本句主语是a significant growth, 是一个趋势, 不能作reach的主语。
因此本句可以改成
The proportion of students enrolled in famous universities showed a significant growth throughout the whole period, reaching 60% in 2005.
四 句式较为单一
比如要表示老年人的比例从1990年的6% 急剧增长到 2000年的21%,同学们一般能想到的基本句式有以下两种:
The percentage of elderly people increased sharply from 6% in 1990 to 21% in 2000.
There was a sharp increase in the percentage of elderly people from 6% in 1990 to 21% in 2000.
但如果文章通篇都是这样的句式,就不符合更高分数的评分标准, 要求有多样的句式结构,我们可以有一些变化:
1 分词作状语描述起点
Starting at 6% in 1990, the percentage of elderly people increased sharply to 21% in 2000.
2 时期做主语
The period between 1990 and 2000 witnessed/ saw/ experienced a sharp increase in the percentage of elderly people from 6% to 21%.
3 before 衔接
The percentage of elderly people was 6% in 1990, before increasing sharply to 21% in 2000.
4 趋势做主语
A sharp increase from 6% in 1990 to 21% in 2000 was seen/shown in the percentage of elderly people.
五 不同时间段的趋势及数据描述上缺少衔接
比如要表述:当地游客的人数急剧增长,在2010年达到顶峰(数值为300万),但是在接下来的五年有轻微下降。
有些同学在看到以后,写的句子是The number of local visitors went up sharply. It reached a peak of 3 million in 2010, but it declined slightly in the next five years.
这样的句子较为简单,我们可以改成
After a sharp increase, the number of local visitors peaked at 3 million in 2010, which was followed by a slight decrease in the next five years.
这里使用after, which was followed by体现了句间的衔接
或者还可以改成:
The number of local visitors surged until 2010, when it peaked at 3 million, prior to a slight decrease in the next five years.
因此备考的同学们应多积累一些衔接方式, 比如
From then on, since then, afterwards, prior to, which is followed by, which precedes a decrease等。
针对以上问题,同学们在拿到题目以后一定要审清对象,在记忆相关单词的时候要结合例句去记,要学会使用多样句式描述趋势,内容组织上注意前后的衔接, 多练习多运用才能取得好成绩。
