问题     What is brain plasticity? Does it mean that our brains are made of plas
tic? Of course not. Plasticity, or neuroplasticity, is the lifelong ability of the
brain to reorganize neural pathways based in new experiences. As we learn, 【M1】______
we acquire new knowledge and skills through instruction or experience. In
order to learn or memorize a fact or skill, there must be persistent functional
changes in the brain that represents the new knowledge. The ability of the 【M2】______
brain to change with learning is that is known as neuroplasticity. 【M3】______
    To illustrate the concept of plasticity, imagine the film of a camera. Pre
tend that the film represents your brain. Now imagine using the camera to
take a picture of the tree. When a picture is taken, the film is exposed to new 【M4】______
information—that of the image of a tree. In order the image to be retained, 【M5】______
the film must respond to the light and change to record the image of the tree. 【M6】______
Still, in order for new knowledge to be retained in memory, changes in the 【M7】______
brain representing the new knowledge must happen. 【M8】______
    To illustrate plasticity in another way, imagine making an impression of
a coin in a lump of clay. In order for the impression of the coin to appear in
the clay, changes must occur in the clay—the shape of the clay changes as
the coin is pressing into the clay. Similarly, the neural circuitry in the brain 【M9】______
must reorganize in return to experience or sensory stimulation. 【M10】______ [br] 【M6】
选项
答案 respond — react
解析 respond和react有相似之处，即都有前缀re-，都和介词to搭配。但是从含义上来说，两者是不一样的。前者是指用行为或言语对别人的行为或言语作出响应或答复，而后者是指因为某一个事件的发生而发生某种反应，有因果关系包含其中。句中说胶卷因为光线而产生某种反应，所以应该用react。
