从括号中选择合适句子的单词
Please_____ (seal,send) the letter before you post it.
这道题我原本是选send 可答案是seal 为什么？
What language will people______ (speak,say) in the future?
答案是 speak
说语言 语种 用的是speak
但是 有what what 是问名词的 say+内容 内容就是名词 为什么 不能用 what呢？

用所给动词的适当形式填空
Vegetables______at a good price in early spring.(sell)
答案是 are sold
这句话是什么时态？
为什么用are sold 不能用sell

我来告诉你！
send是发送的意思，如果用send，那语法无错，但是语言逻辑方面不切合，你想想，“寄出去之前发送过去”语义显然不通。
接着看你第二个疑惑点，谁说“内容就是名词”呢？
say+说话的内容，这里显然不能使用。
接着，be动词后加被动语态或现在进行时，显然不是后者，故用被动语态（动词-ed形式）

seal 是正确的，翻译：在你邮这封信前，请将其密封好。
将language 去掉就用say,say +what (what后就不能有任何词）
are sold 这里是一般现在时的被动语态。构成：am/is/are +过去分词构成
翻译成：在早春，蔬菜都是以高价进行出售
