helpers - animals.

Scientists(科学家们) want to know what warnings(预兆) the animals sense(感觉). They
know that animals sense more than(比……多) humans(人类)do. Many animals can see,
hear and smell things that people do not even notice(注意).Some can sense small changes
(变化) in air pressure(大气压) or gravity(重力).This sense helps animals predict quakes.

quakes often come before or after a large one.) There is a low sound before each quake.
Each sound makes the dogs bark(大叫). A scientist looks at his machine(机器). It seems
(看上去) there is a loud noise, too. The scientist finds that the dogs can sense quakes, but
humans feel and hear nothing.
