We’ll go to school tomorrow. 我们明天要去上学。
⑵take＝buy，是“买下”的意思。在口语中，当表示买下某物时经常用take，而很少用buy。

You can’t take it, it’s too dear. 你别买它，它太贵了。

How much are these socks? 这些短袜多少钱？
⑴how much多少钱，用来询问价格。若所询问的东西是不可数名词或可数名词的单数时，谓语用is；所询问的东西是可数名词复数或不止一种东西时，谓语用are。如：
How much is the rice? 这大米多少钱？
How much are these things? 这些东西多少钱？
⑵how much多少，用来提问数量，后面加不可数名词。如：
How much water is there in the bottle? 瓶子里有多少水？
注：how many也用于提问数量的多少，但后面必须加可数名词的复数。请比较：

How much meat do you want? 你想要多少肉？
