Passage Two

听力原文

    (12) Eat Grub is Britain’s first new food company that breaks western food boundaries by introducing edible insects as a new source of food. And Sainsbury’s is the first UK supermarket to stock the company’s crunchy roasted crickets.

    Sainsbury’s insists that such food is no joke and could be a new, sustainable source of protein. Out of curiosity, I paid a visit to Sainsbury’s. As I put my hand into a packet of crickets with their tiny eyes and legs, the idea of one going in my mouth made me feel a little sick. (13) But the first bite was a pleasant surprise. A little dry and lacking of taste, but at least a wing didn’t get stuck in my throat. The roasted seasoning largely overpowered any other flavor although there was slightly bitter aftertaste. The texture was crunchy, but smelt a little of cat food. Eat Grub also recommends the crickets as a topping for noodles, soups and salads.

    (14) The company boasts that its dried crickets contain more protein than beef, chicken and pork, as well as minerals like iron and calcium. Unlike the production of meat, bugs do not use up large amounts of land, water or feed, (15) and insect farming also produces far fewer greenhouse gases. However, despite two billion people worldwide already supplementing their diet with insects, “consumer disgust” remains a large barrier in many western countries. I’m not sure bugs will become a popular snack anytime soon, but they’re definitely food for thought. 

15. What does the passage say about insect farming?

解析：A。录音后面部分讲到，昆虫的加工生产不会耗费大量的土地、水和饲料，而且相较于肉类生产，它产生的温室气体要少得多，A项中的environmentally friendly是对这一内容的概括，因此选A。录音中提到昆虫加工生产不会消耗大量的土地、水或饲料，但并未提到会节省劳动力，D项属于过度引申，故排除。B、C两项未提及，故排除。
