Dear friends，
Have you noticed that the number of rare animals is on the decrease？With our environment going worse，many animals can’t adapt themselves to the new changes so that many species are endangered or have even died out.Besides，human activity also has a great influence on them.For example，people often kill them in order to get their meat or fur.Animals are our friends.They play an important role in keeping the balance of nature.We can’t live without them.What’s more，both humans and animals should share the earth equally.To show our love to animals can definitely help us live more happily.
To conclude，please remember your care can make a difference.Join us in protecting our best friends—animals.名师点睛
本文层次清楚，第一段描写动物受到威胁的现状，第二段是动物对人类的重要性，第三段提出了倡议。作者的遣词造句还有以下特点：(1)短语的有效运用。文中出现了大量的短语，如：on the decrease，adapt oneself to，die out，have a great influence on，in order to，play an important role in，make a difference等，这些短语的恰当使用丰富了文章的语言，也有助于准确地表达文意。(2)较复杂句式的使用也是该文的一个亮点，如：with复合结构和so that句型。(3)作者成功地使用了多个副词来表达强烈的感情，如：equally，definitely等。自主排查　语境提升直击重点　突破考点内容索引教材升华　综合运用自主排查　语境提升Ⅰ.写作必记单词
