题目

阅读理解     My name is Richard Terry. I'm a soil scientist and science professor at Brigham Young University, in Provo, Utah.     I grew up on a farm in Idaho, but I didn't want to become a farmer. Milking cows every morning before school and every afternoon after school forced me to go to university and become a scientist. I enjoyed my science courses at university, but once I saw the application of chemistry, math and physics in soil science, I knew that was what I wanted to focus on in my career.     In my eyes, working as soil scientists is important. We often do some research on soil and sand, which is very useful for planting and farming. In the field, my students and I use shovels, trowels(泥刀) and drilling devices to collect soil samples. In the laboratory, we use chemicals to collect nutrients that were left on the soil surface by ancient people.     Since 1997, we've been studying the soils of ancient Maya settlements in what is now Guatemala. We set about looking for ancient waste piles that were left from food processing and waste disposal(废物处理)by the Maya. The organic matter has rotted and been lost from the soil. However, phosphorus(磷), has been adhered to soil, where it has remained for thousands of years. We then used these techniques to determine the locations of ancient kitchens and workshops. One of those workshops was used to make polished mirrors that the King of Aguateca wore when performing ceremonies. Archaeologists found carved stones in that workshop that were once part of the king's crown. We then started to examine the soils of large public shopping centres to find chemical remains of ancient marketplace activities. We are currently examining the organic matter of the soil to find the remains of ancient corn plants. This is of great use to help us to determine where corn was grown.   (1) Richard Terry started to show interest in soil science       .   A . after he went to university B . when he learned to milk cows C . when he was a young boy D . when he helped to work on a farm (2) What does Richard Terry think of his job as a soil scientist?
