Answer 1

分析 高分句型：
句型一：Trees also provide us with lots of fruit树也为我们提供了大量的水果．provide sb with sth向某人提供某物．also也，用于实义动词前．lots of=a lot of，许多，大量的．可以修饰不可数名词或可数名词复数．fruit指"水果"时，为集体名词，只用单数，不用复数．
句型二：Many things in our daily life are from trees such as desks，chairs，doors，beds and so on．我们日常生活中的许多东西都是来自树，如书桌，椅子，门，床等．主语是things，in our daily life在我们日常生活中，做后置定语．be from来自．things是复数，因此用are．such as例如．and so on等等．

解答 Trees are very helpful to us
Trees are very helpful to us（中心句）．They can take in the harmful gases and produce oxygen（树的作用）．They can cool and clean the air（对空气的作用）．Trees are the best fighters against pollution（对环境的作用）．Many things in our daily life are from trees such as desks，chairs，doors，beds and so on【高分句型一】．Trees also provide us with lots of fruit【高分句型二】（对人类的用途）．What's more，they can make our city more beautiful，so they are very helpful in our life（总结）．

点评 写作时要明确要点，做到思路清晰，句式灵活，表达流畅，语法正确，结合要求，注意作文题材，不要写跑题．日常积累一些短语和词句．
