老师：Hello everyone. Last time we have Learned 2 reports. Today we are going to first review what we have Learned in the last lesson and learn the usage of some new words. Then we will write a letter about earthquake safety tips with the new words above.
老师：We have Learned two news reports last time and we have discussed what can be done to prepare for a natural disaster. First, let's learn some new words for further study. First, look at the sentence and pay attention to the new words, injured and at large. First let's look at injury. It means to harm yourself or somebody else physically, especially in an accident. It can also means to damage somebody's reputation, pride, etcetera. For example, three people were killed and five injured in the crash.
老师：Here injure means social. This could seriously injure the company's reputation. Here in your means, its long form is injury and its adjective is injured. At large. It means as a Howard in general.
老师：For example, this article represents the opinion of the public at large. Here at large means from band. And the next sentence here we should pay attention to the word reaction.
