应对上面这个题目(《剑桥15》真题)，考官是如何写“实线”上的这些总数的呢?
我们从2010年、2012年、2013年、2014年这四年的表述中来一探究竟：
In the year 2010, there were a quarter of a million visitors that stayed on cruise ships, while another 750000 visitors were staying on island that totals up to a million of visitors during that year.
解析：
“total up to 总计达…” 此处total为动词用法
that关系代词引导定语从句，基于主句部分的2个数据补充说明其总和
Moving on, the number of visitors staying on cruise ships decreased to 250000 visitors in the year 2012 while the number of visitors staying on island increased to 1250000 people. This sums up to an amount of 1500000 visitors that year.
解析：
“sum up to 总计达” 此处sum为动词用法
this代词，指代了前一个句子中的信息，基于前文的2个数据补充说明其总和
In the year 2013, 500000 visitors stayed on cruise ships while 1500000 visitors stayed on island that adds up to 2 million visitors that year.
解析：
“add up to 总计达” 此处add为动词用法
that关系代词引导定语从句，基于主句部分的2个数据补充说明其总和
During the next year which is 2014, a total at one million visitors stayed on cruise ships while the same number of visitors staying on island remained consistent which is 1500000 people, totaling up to two million and a half visitors that year.
解析：
为了区别于上文的“total up to”在定语从句中的用法，本句中考官改写that totals up to …为现在分词短语totaling up to，依然起到了伴随补充说明的作用
小结：
除了掌握“总计达”的多种表述之外，我们需要关注的是在写作中，词汇分不要全依赖高大上的难词，一些常规用词的罕用词性也很容易在表述上突出，能够有效实现用词不重复以及表述精 准的要求。
其次，还可以在语法结构上动手脚，如以上的定语从句结构、分词短语结构、代词引起的独立句子等
