千万别这样答雅思写作地图题！事情是这样的，我只要看到学生地图题里使用become, 就头皮发麻。所以，我借一个地图题讲解一些好的替换方式。
雅思12 Test2地图题
The maps below show the centre of a small town called Islip as it is now, and plans for its development.
以下3幅图中红色标注的部分，都发生了变化。
（一）
main road变成了pedestrians only.
1) The main road will become pedestrians only.
如果不想思考，只想“按照”图形所给信息写作文，可能会写出这样的句子来。
现在，我们来考虑一下该句表达的意思。
“路变成了人”，我们试想一下，当砂石、水泥等修建的路变成人类的时候，这个世界将变成什么样子。改雅思作文，感觉像看看了一部恐怖电影。
这个错误非常严重，但是为什么有人不能发现呢？因为他们总是告诉自己：我写的是对的。
那这么改呢？
如果只使用图中的信息，我们就必须考虑pedestrians（行人）和road的关系。pedestrians在road行走（希望这一点在考鸭们的认知范围内）。所以，句子可以写成：
2) Only pedestrians will be allowed to use the middle section of the main road.
你至少要写出这样的句子来，它可以向考官表明你是一个具备基本认知能力的人。
然而，这个句子存在错误。当road只允许行人使用的时候，它就已经不再是“主干道”了。所以，事实上，2) 句中的main road根本就已经不存在了，它变成了“人行道”——a pedestrian walkway. 于是，句子应该改成：
3) The middle section of the main road will become a pedestrian walkway.
确实，此处become可以用来应付雅思写作地图题了。但是，这里的become是不好的表达（语确，看得懂，但是不合适）——显然公路无法自己变成人行道。
事实上，是人让公路“变成”了人行道。当然，我们不会在写作文里边去写修路工人，所以会使用被动句——公路被改成了人行道。
被改成了，比较通俗的表达是be converted into, 得到：
4) The middle section of the main road will be converted into a pedestrian walkway.
当涉及到建筑的时候，converted就可以更具体——“重建”reconstructed, 得到：
5) The middle section of the main road will be reconstructed into a pedestrian walkway.
小结
1) The main road will become pedestrians only.（误）
2) Only pedestrians will be allowed to use the middle section of the main road.（烂）
3) The middle section of the main road will become a pedestrian walkway.（将就）
4) The middle section of the main road will be converted into a pedestrian walkway.（正）
5) The middle section of the main road will be reconstructed into a pedestrian walkway.（正）
（二）
main road北侧的shops变成了bus station, shopping centre, car par, new housing.
1) Shops along the northern side of the main road will become a bus station, a shopping centre, a car par and a new section of housing.
请问，按照你的常识，一家商店如何变成停车场？当然是把商店拆了，然后在空地上配备停车场需要的简单设施。所以，这里的become是非常不合适的，虽然语确且猜得出想表达的意思。
我现在介绍另一个词替换become: be replaced by. 得到：
2) Shops along the northern side of the main road will be replaced by a bus station, a shopping centre, a car par and a new section of housing.
补充：
以上2) 句能展示图形所给的信息吗？
不能。
显然bus station, shopping centre, car par, new housing按照自西向东的顺序排列（需要写出来）。
那方向如何引入？
3) Shops along the northern side of the main road will be replaced by a bus station, a shopping centre, a car par and a new section of housing from west to east.
勉强可以理解3) 句想表达的意思，但是正确的写法是：
4) Shops along the northern side of the main road will be replaced by a bus station, a shopping centre, a car par and a new section of housing from west to east, all four of which are situated in a line from west to east.

小结
1) Shops along the northern side of the main road will become a bus station, a shopping centre, a car par and a new section of housing.（误）
2) Shops along the northern side of the main road will be replaced by a bus station, a shopping centre, a car par and a new section of housing.（信息不全）
3) Shops along the northern side of the main road will be replaced by a bus station, a shopping centre, a car par and a new section of housing from west to east.（将就）
4) Shops along the northern side of the main road will be replaced by a bus station, a shopping centre, a car par and a new section of housing from west to east, all four of which are situated in a line from west to east.（正）
（三）
main road变成了dual carriageway.
1) The main road will become a dual carriageway.
能写出这句话的同学，脑洞真的很大。
他们的想法应该是，以前用于行车的公路没有了，取而代之的是一条环形的公路。
我们来细细地考虑一下图形中的变化。事实上，main road变成了人行道，而dual carriageway占用的是其他的地方，完全是新建的。所以，应该写成：
2) A dual carriageway will be built.（不去扯main road, “变成”完全用不上）
become可能的替换有哪些？
1. be converted into
2. be reconstructed into
3. be replaced by
