题目解答
答案
（1）细节理解题。根据第一段Many people prefer junk food to healthy food because they develop a taste for it.（许多人更喜欢垃圾食品而不是健康食品，因为他们对垃圾食品产生了兴趣。）以及第二段Food companies and restaurants choose to use trans fat oils because they're cheap and they make baked goods last longer.They also improve the taste of food.（食品公司和餐馆选择使用反式脂肪油，因为它们便宜，而且可以使烘焙食品保存更长时间。它们还能改善食物的味道。）可知人们喜欢垃圾食品是因为它的味道。故选C。
（2）细节理解题。根据第二段Food companies and restaurants choose to use trans fat oils because they're cheap and they make baked goods last longer.（食品公司和餐馆选择使用反式脂肪油，因为它们便宜，而且可以使烘焙食品保存更长时间。）可知在食品生产中使用反式油脂是因为它能降低成本。故选D。

（4）代词指代题。根据划线词前一句Food makers must attach a Nutrition Fact label to their products.（食品制造商必须在产品上贴上营养标签。）可知划线词所在句的意思是：这些列出了每日推荐摄入量，并详细列出了产品中的所有成分，包括反式脂肪（如果使用的话）。因此推断these指代前一句提到的label（标签）。A.The labels标签；B.The recipes食谱；C.The products产品；D.The restrictions限制。故选A。
（5）段落大意题。通读最后一段尤其是Another way is to avoid eating out，especially in fast-food restaurants.（另一种方法是避免外出就餐，尤其是在快餐店。）可知最后一段主要介绍的是关于健康饮食的建议。故选B。
