你需要找到"老师","想","上周末课"这三个词或短语的英文对应词或短语。
然后对每个词或短语进行翻译。对于"老师",你可以选择翻译成"teacher",或者你也可以用"instructor","mentor","tutor","schoolmaster"等词,取决于上下文。对于"想",你可以选择翻译成"want","desire","hope","wish","mean"等词。对于"上周末课",你可以选择翻译成"hold the class this weekend","give the class this weekend",等。所以,"老师想上周末课"翻译成英语就是:"Teacher wants to hold/give the class this weekend".
