问题 A.  by removing
B.  made
C.  and help
A. 【T7】________in the surface of the ground
B. 【T8】________support the roots of future crops
C. 【T9】________the plants that protect the soil from being blown or washed away
    Farmers usually use ploughs to prepare their fields for planting crops. Ploughs cut into the ground, and lift up weeds, and other unwanted plants. However, ploughing is blamed for causing severe damage to topsoil【T10】________Many farmers in South Asia are now trying a process called Low Till Farming. Low Till Farming limits the use of ploughs. In this method of farming seeds and fertilizer are put into the soil through small cuts【T11】________Low Till Agriculture leaves much or all the soil and remains of plants on the ground. They serve as a natural fertilizer【T2】________They take in rain and allow it to flow into the soil instead of running off. It has been proved that Low Till Farming increases harvests and reduces water use, and this method reduces the need for chemical products because there are fewer unwanted plants.
【T10】
选项 A、 
B、 
C、 
答案C
解析 本题句的主要成分齐全，要填入的成分应作定语或状语。如果选A项，结构上作后置定语修饰damage，但在意思上“in the surface of the ground”与“topsoil”重复，故排除A。若选B项，在意思上前后不一致，前面是负面意思“ploughing is blamed for causing severe damage to topsoil”，后面则是表示正面的积极意义“and help support the roots of future crops”，排除B。C选项“by removing the plants that protect the soil from being blown or washed away”符合语义，以除掉植物的方式对表层土造成损害，而这些植物起到保护土层不被风刮走或不被雨冲刷走的作用，故选C。
