2022年7月23日雅思大作文题目

More and more people move from the countryside to big cities. Does this development bring more advantages or disadvantages to the environment?

高分范文及解析

Introduction

Ø urban heat island effect n. 城市热岛效应

Ø metropolitan adj. 大都市的

Ø wreak havoc on v. 对…造成威胁

Ø contaminant n.[C] 污染物

Ø amass vi. 聚集

Ø be saturated with adj. 充斥着

Ø migrate vi. 迁徙

Ø covert vt. 使转变

Ø greenery n. 绿色植物

However, this is merely an incomplete part of the whole picture. As a matter of fact, the urban area teeming with the sea of people fails to alleviate, or even worse, fuels the urban heat island effect. This is mainly beca
