_______useful the dictionary you gave me last week is!
A．How B．What a C．How a D．What an
A
【解析】
试题分析：感叹句主要有what和how构成：
1、what修饰名词或名词短语，有以下两种形式： 1. What+a(an)+（形容词）+单数可数名词+主语+谓语！或是：What+名词词组+主语+谓语！ 2. What+(形容词）+可数名词复数或不可数名词+主语+谓语！
2、How引导的感叹句。 how用来修饰形容词、副词或动词。其结构是：How+形容词（副词）+主语+谓语！
结合语境可知选项BCD结构有误，故选A。
考点：感叹句
点评：当how修饰动词时，动词不跟着感叹词提到主语之前。 what与how引导的感叹句，一般情况下可以相互转换，转换后意义不变。在口语中，感叹句的主语和谓语常常省略。

Nearly all our food comes from the soil（土地）. Some of us eat meat, of course, but animals live on plants. If there were no plants, we would have no animals and no meat. So the soil is very necessary for life. The top of the ground is usually covered with grass or other plants. There may be dead leaves and dead plants on the grass. The waste matter（粪）from animals also falls on it.
All soil needs food. If we do not give it any, the plants will be weak. Farmers found that animals’ waste is the best food for the soil, but chemical fertilizers（化肥）are also very useful. The same crop（庄稼）should not be grown in the same place every year, it’s better to have a different crop. A change of crop and the use of a good fertilizer will keep the land good.
