1、Obviously, if we don't control the problem, the chances are that... will lead us in danger. 很明顯，如果我們不能控制這一問題,很有可能我們會(huì)陷入危險(xiǎn)。

"the chances are that"替代了"may"，果然說話拐彎的生物不止是中國(guó)人。

2、No doubt, unless we take effective measures, it is very likely that... 毫無疑問，除非我們采取有效措施，否則很可能會(huì)……

作文結(jié)尾萬用句，毫無破綻。

3、It is urgent that immediate measures should be taken to stop the situation. 應(yīng)立即采取措施阻止這一事態(tài)的發(fā)展。

"It is urgent that"+被動(dòng)，效果不錯(cuò)滴。
