【題目】When traveling, you sometimes have to go somewhere alone, always ____ your attention on your belongings.

A. focusing B. focuses C. focused D. focus

【答案】A

【解析】

試題分析：考查分詞做狀語。本句中動(dòng)詞“focus one's attention on聚焦于....”與主語you構(gòu)成主動(dòng)關(guān)系，所以使用現(xiàn)在分詞在句中做伴隨狀語。句意：當(dāng)你旅行的時(shí)候，有時(shí)候，你不得不獨(dú)自去某個(gè)地方，這時(shí)你總是要聚焦于自己的財(cái)產(chǎn)。故A正確。
