雅思考試分學術類和培訓類兩種，分別針對申請留學的學生和計劃在英語語言國家參加工作或移民的人士。考試分聽、說、讀、寫四個部分，總分9分。下面小編給各位雅思考生們帶來雅思寫作Task1小作文流程圖範文：自然碳迴圈，供大家備考參考，希望對同學們的備考有所幫助!
Task：The diagram below illustrates the carbon cycle in nature.
思路解析：
1. 需要看懂圖形之間的順序，並找到流程的'起點和終點;
2. 需要理解圖形之間的因果關係;
3. 需要學會描述事物之間的轉換：如空氣變成固體;
4. 需要理解和推測文字描述和圖形步驟之間的因果關係：如前提條件，過程，後果。
雅思寫作參考範文：
The flow chart shows how the cycle of carbon is formed in the nature completely. Overall, this process has 3 main parts, including carbon absorbing, transferring and releasing.
Firstly, under the exposure to sunlight, plants like green trees begin a process known as photosynthesis which absorbs CO2 from the air. After the death and decay of these plants, the organic carbon is then transferred underground. Similarly, the carbon accumulated in dead animals which feed on plants in life, such as sheep, is also deposited in soil. Being pressed and mingled in deep earth for a long term, a part of trapped carbon is converted into the form of fossil or fossil fuels.
In terms of releasing carbon back, there are generally 3 ways. Organically, physical respiration from both plants and animals produces and exhales large amount of carbon as CO2 into atmosphere. Spontaneously, root respiration of plants also extracts fixed carbon from soil. Besides, man-made activities that burn fossil fuels like car running or factory manufacturing make serious gas emissions of CO2 in air.
Finally, the entrance of CO2 into atmosphere activates this natural cycle which consists of sun, air, creatures, land and human activities.
