Question

A bowl of soup a day could keep the pounds at bay.
Health experts have discovered that adding low-calorie vegetable soup to the start of a meal can actually help to lose weight. Because you tend to feel full sooner, you eat less of your main course.
The soup method was tested by researchers at Pennsylvania State University, led by Dr Barbara Rolls. They found that when participants in the study ate a first course of soup before lunch they reduced their total calorie intake by 20 per cent, compared with those who did not begin the meal with soup. But those who favour creamy soups should beware. Researchers stressed the soup must be low-calorie and based on stock, not cream.
All of the soups tested in the study were made from the same elements—chicken stock (原汁鸡汤), broccoli (菜花), potato, cauliflower (花椰菜) and carrots. They were mixed together to create four different textures and thickness from separate stock and vegetables through to pureed (蔬菜泥) soup.
Scientists thought that thick soups with thick pieces of vegetables which required chewing might be more filling, but to their surprise they found all forms had the same effect. The findings were presented to the Experimental Biology conference in Washington, DC, and the research was part funded by the National Institutes of Health.

DCAB
1.根据第二段意义可知，喝汤会让你很快觉得饱了，所以正餐就能少吃点，从而摄入的总热量就会减少。所以本文阐述的是喝汤为什么会减轻体重。
2.这是一篇生活类阅读材料。健康专家发现，在吃正餐之前喝一碗低热量的蔬菜汤有助于减轻体重。由全文论述的中心推测，此句意义是：一天一碗汤，脂肪全减光。
3.根据第三段“他们发现，与那些饭前不喝汤的人相比，如果研究对象在午餐前先喝了一碗汤，他们这顿饭所摄入的总热量就会减少20%。”可得答案。
4.根据第三段最后一句：研究人员强调，这种汤的热量必须低，要以汤为主要原料，而不是奶油。短文第四、五段提到：汤的原料有：鸡汤、菜花、马铃薯、花椰菜和胡萝卜（不包含奶油）；不同质地、不同浓度的汤功效都一样，故可排除A、C、D。
