【正文】 和“pay attention to”屬于被動關(guān)系，所以第一個空用“should be paid attention to”結(jié)構(gòu)，所以排除A、B；had better not do/be意為“最好不做某事”；against“反對”，介詞，所以第二個空用動詞短語be against “反對”。might也許；must必須；mustn’t禁止；may也許。6．B解析：B【詳解】句意：——這周五郎朗會去藝術(shù)中心表演嗎？——是的。考查情態(tài)動詞辨析。mustn’t禁止；should應(yīng)當(dāng)；can會、能；needn’t不需要。4．C解析：C【詳解】句意：——小心！火有時候會很危險。她總是這個時候回家。分析句意可知，交通燈變綠之前橫穿馬路，汽車有可能會撞到你，故此處應(yīng)用may表推測。2．B解析：B【詳解】句意：在交通燈變綠之前不要橫穿馬路。needn’t不必，指沒必要；can’t不能，指不能夠；shouldn’t不應(yīng)該，表建議；mustn’t不能，表禁止。 holding D．to gather。get used to it in winter.A．can’t B．needn’t C．mustn’t D．shouldn’t19．Dr. Zhong Nanshan once said, To prevent the spread of this disease, we________never be too careful.A．can B．may C．must D．should20．It’s amazing that the pen ________turn voice into text with few mistakes.A．can B．must C．may D．need21．—Could you tell me how to renew the library books?—With pleasure.
