把这段文本从中文翻译成英文。


很多人认为机器翻译已经足够好，但事实并非如此。

语言是逻辑与意义的表达，需要更多的广度和深度的理解。因此，机器翻译仍然面临许多挑战，例如歧义、语法错误和文化障碍等。

此外，人类翻译师可以考虑上下文和文化差异，从而更准确地传达信息。这是机器翻译仍然无法完全替代人类翻译的主要原因之一。
Many people believe machine translation is good enough, but that's not the case. Language is the expression of logic and meaning, which requires a greater breadth and depth of understanding. Therefore, machine translation still faces many challenges such as ambiguity, grammatical errors, and cultural barriers. Moreover, human translators can consider context and cultural differences to convey information more accurately. This is one of the main reasons why machine translation cannot completely replace human translation.
