英语没听懂应该怎么说

If you don't understand something that has been said in English, you can try asking the speaker to repeat themselves or to explain what they meant in different words. You could also ask for clarification or context, or ask the speaker to speak more slowly. It's also a good idea to practice your English listening skills by listening to a variety of different speakers and practicing with native speakers or language learning resources. If you're in a situation where you need to communicate in English but are having difficulty understanding, it may be helpful to have a bilingual friend or colleague present to help facilitate communication.
