A、must
B、should
C、shall
D、can
【正确答案】：D
【题目解析】：在第21题中，给出的句子是“Now you _____21_____ do both at the same time.”，这里的关键是选择一个能够表达“现在你可以同时做这两件事”的词语。 选项A的“must”表示“必须”，带有一种强制性的含义，与句子中表达的“现在”和“可以”的意味不符。 选项B的“should”表示“应该”，通常用于给出建议或表达一种理想状态，而不是描述实际情况或能力。 选项C的“shall”常用于正式或法律语境中，表达一种将来时态的命令或规定，不适合这里表达的能力或可能性。 选项D的“can”表示“可以”，正好符合句子的语境，表达了现在有一种可能性或能力，可以同时进行购物和看电视这两种活动。 因此，正确答案是D，即“can”。这个答案准确地表达了句子中想要传达的意思，即现在人们有了同时购物和看电视的可能性。
