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壹問題,很有可能我們會陷入危險。
"the chances are that"替代了"may"，果然說話拐彎的生物不止是中國人。
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……
作文結尾萬用句，毫無破綻。
3、It is urgent that immediate measures should be taken to stop the situation. 應立即采取措施阻止這壹事態的發展。
"It is urgent that"+被動，效果不錯。
