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 (原汁雞湯), 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.

1.根據(jù)第二段意義可知，喝湯會讓你很快覺得飽了，所以正餐就能少吃點(diǎn)，從而攝入的總熱量就會減少。所以本文闡述的是喝湯為什么會減輕體重。
2.這是一篇生活類閱讀材料。健康專家發(fā)現(xiàn)，在吃正餐之前喝一碗低熱量的蔬菜湯有助于減輕體重。由全文論述的中心推測，此句意義是：一天一碗湯，脂肪全減光。
3.根據(jù)第三段“他們發(fā)現(xiàn)，與那些飯前不喝湯的人相比，如果研究對象在午餐前先喝了一碗湯，他們這頓飯所攝入的總熱量就會減少20%�！笨傻么鸢�。
4.根據(jù)第三段最后一句：研究人員強(qiáng)調(diào)，這種湯的熱量必須低，要以湯為主要原料，而不是奶油。短文第四、五段提到：湯的原料有：雞湯、菜花、馬鈴薯、花椰菜和胡蘿卜（不包含奶油）；不同質(zhì)地、不同濃度的湯功效都一樣，故可排除A、C、D。
