问题 Leptin is effective in reducing weight but it’s many years away before humans can use it. [br] If excess leptin is present, the brain signals the body to increase food intake and to become more active.
选项 A、Y
B、N
C、NG
答案 B
解析 本文第四段的倒数第二句话：Thus when leptin is low，hunger pangs increase．．．when leptin is high，everything reverses．当动物体内的leptin水平较低时，因饥饿引起的胃痛加剧，体温下降，新陈代谢趋缓；而leptin水平高时，情况正相反。因此本题表述的正是lepfin水平较低时的情况。
