网考网参考答案：C
网考网解析：
[解析] 考查动词辨析。propose“提议，建议”，prolong"延长”，guarantee“保证，担保，确保”，guard“守卫，保卫，保护”。能和。food safety搭配的只有guarantee和guard，而这句话的主语是these dates，就是上文所提到的食品包装上标记的保质期等日期，these dates不能和guard搭配，因为dates无法采取保护措施，于是答案是C．guarantee。这句话的意思是：但是这些日期不能真正确保食品安全。 document.getElementById("warp").style.display="none"; document.getElementById("content").style.display="block"; 查看试题解析出处>>
