After shaking the east coast of Honshu, Japan on March 11, the earthquake has caused more than 10, 000 deaths and 17, 000 people missing. In downtown of Tokyo, buildings shook and frightened citizen blocked out all the streets and roads. The tsunami（飓风）afterwards, which caused more deaths and injury, made Japanese people unable to cheer up. “Now that our neighbors are in trouble,” the Foreign Ministry spokesman said, “we are in our turn to give a hand. Our rescue team has already got there in time to help.” The terrible earthquake also caused a big fire breaking out at the Fukushima nuclear power plant（福岛核电站）, leading to a radiation leaking（泄漏）.
50 nuclear workers, facing radiation and fire, became the only people remaining at the Fukushima nuclear power plant on Tuesday — and perhaps Japan’s last chance of preventing a broader nuclear danger. They have volunteered to put seawater on dangerous nuclear fuel（核燃料）to cool it down, to prevent thousands of tons of radioactive dust high into the air. Some scientists suggest that the leaking is harmful to human being and may influence human body through rain or snow from the sky in the future.
