優秀英語作文批改：警察持槍的優缺點討論

Nowadays, prevention of increasing criminal rates could be a thorny problem. There has been a controversial issue regarding whether police need be armed, one accepted statement is that it leads to the rise of the level of violence. Personally, I disagree with this view.

1. 首先我需要表揚你寫得不錯，有兩個點

1)犯罪成本的上升，罪犯可能因爲怕死而不敢犯罪。

2)持槍可能使罪犯誤傷街上的老人。

以上兩點是你的觀點，而且topic sentence寫得還可以，只是你沒有像我一樣將“擔心死亡”上升到“犯罪成本的提高”，你只是簡單地翻譯出來而且用了lose life這樣不地道的口語表達，而且第二點用for example 連接不妥，明明在說第二件事情，“比如”什麼呢?邏輯不要亂。用in addition 或者secondly更顯得用層次感。

2. 開頭的it指代不明。

修改後：

Police being armed might be an effective method that deters criminals and hence decrease the criminal rates. First, this increases the possibilities that some offenders give up the criminal minds if crime costs have risen significantly, which implies that potential offenders might consider the possible consequence to be death. In addition, elderly people could be injured accidentally by in the street. Nevertheless, this type of crimes is gradually disappearing because of the deterrent of police carrying guns.

1. 兩段寫得都是持槍不好的觀點，分別是：

1) 刺激罪犯買槍與警察對峙。

2) 警察可能不理智會誤傷。

這可以是持槍不好的兩個理由，爲什麼要強分兩段呢?第一個主體段是兩個觀點，第二個主體段就必須也是兩個觀點(或例子)這就叫“平行段”。

2. alternative就帶有另外一種的意思，再用other就重複了。

修改後：

On the other hand, with the increasing number of police with guns, it will increase the level of violence. Because for many criminal groups, being armed is a basic condition against the threat from police, while this action results in crimes to innocent citizens easily. Additionally, some police might abuse their authority subjectively. Police is likely to lose the control of emotions when confronting criminals, this may increase the rate of unnecessary death. Therefore, adopting an alternative way to deter potential criminals (such as anesthetic rifle) may be better for police enforcement.
