1. Green anole lizards, familiar to schoolchildren as chameleons, have recently become familiar to biologists as an excellent animal for laboratory studies of the interaction between stimuli with hormones. (A) an excellent animal for laboratory studies of the interaction between stimuli with (B) an excellent animal for laboratory studies of interaction of stimuli and (C) being excellent animals for laboratory studies of the interaction between stimuli with (D) excellent animals for laboratory studies of the interaction between stimuli with(E) (E) excellent animals for laboratory studies of the interaction of stimuli and 我对于答案有一点点地疑惑,所以我选了B。我认为这里表示的是一种总体的客观的评价,因该用单数。比如: 猫是一种有4个脚的动物,明显,这里和人类都有2个耳朵那种类似,单数表示一种客观的。。
