写的很详细,不过作文不大正确。三个points应该如下 1. Some drivers know the locations, they drive faster between two speed cameras. Also, they may drive close to another car, trying to hide theirs from speed cameras. 2. Speed cameras cannot replace police officers, since officers do many other jobs that can also reduce traffic accidents. 3. Speed cameras do not necessarily work properly. For example, they may record speed slower than the actual speed is, and some drivers will use this wrong record as evidence in traffic courts, which will cause courts troubles. According to reading, speed cameras can help traffic courts. Writing speed camera,阅读说在highway上安speed camera好 |
