In many countries, it is convenient for people to buy a variety of food from all over the world.

To what extent do you think the benefits outweigh the disadvantages?

应对这道题时

考生如此设计了一段结构

There are two main reasons why being able to buy food from around the world is advantageous. Firstly, it gives people the opportunity to eat a wider range of different kinds of foods. …（此处为论证） Additionally, it is good for the customers’ health as they can take in different kinds of nutrients. …（此处为论证）

☆ 谨慎使用代词

改写如下

… Additionally, eating a wider range of food is beneficial because it means that people consume a wider variety of nutrients.

☆ 先看原文，firstly之后使用了it，这个it是清晰可理解的，指代“being able to buy food from around the world”。那么additionally后面的it呢？考生的本意当然还是指代“being able to buy food from around the world”，然而，在句子中穿插了论证的前提下，我们很难做到“隔山打牛”啦！为免歧义，不如直接将其指代的内容换个措辞写出来吧~
