我不能阻止他用英文怎么说

你可以说 "I can't stop him from using Engpsh." 来表示你不能阻止他用英语。

这句话的来源是从动词 "stop" 和介词 "from" 派生而来。"Stop" 意思是阻止或者停止，而 "from" 意思是从……中。所以 "stop from" 的意思就是从……中阻止或者停止。

下面是一些英文例句及其中文翻译：

"I can't stop him from talking." (我不能阻止他说话。)
"She can't stop him from smoking." (她不能阻止他抽烟。)
"They can't stop him from playing video games." (他们不能阻止他玩电子游戏。)

注意，上面的例句都使用了否定形式，表示不能阻止。如果你想表示能够阻止，可以把 "can't" 改成 "can"。例如：

"I can stop him from talking." (我能阻止他说话。)
"She can stop him from smoking." (她能阻止他抽烟。)
"They can stop him from playing video games." (他们能阻止他玩电子游戏。)
