题干：Most episodes of absent-mindedness--forgetting where you left something or wondering why you just entered a room--are caused by a simple lack of attention, says Schacter. Youre sup-posed to remember something, but you havent encoded it deeply. Encoding, Schacter explains, is a special way of paying attention to an event that has a major impact on recalling it later. Failure to encode properly can create annoying situations. If you put your mobile phone in a pocket, for example, and dont pay attention to what you did because youre involved in a conversation, youll probably forget that the phone is in the jacket now hanging in your wardrobe (衣柜). Your memory itself isnt failing you, says Schacter. Rather, you didnt give your memory system the information.it needed. Lack of interest can also lead to absent-mindedness. A man who can recite sports statistics from 30 years ago, says Zehnski, may not remember to drop a letter in the mailbox. Women have slightly better memories than men, possibly because they pay more attention to their environ-ment, and memory relies on just that. Visual cues can help prevent absent-mindedness, says Schacter. But be sure the cue is clear and available, he cautions. If you want to remember to take a medication (药物) with lunch, put the pill bottle on the kitchen table--dont leave it in the medicine chest and write yourself a note that you keep in a pocket. Another common episode of absent-mindedness: walking into a room and wondering why youre there, Most likely, you were thinking about something else. Everyone does this from time to time,says Zelinski. The best thing to do is to return to where you were before entering the room, and youll likely remember.问题：Why does the author think that encoding properly is very important?A.It helps us understand our memory system better.B. It enables us to recall something form our memory.C. It expands our memory capacity considerably.D.It slows down the process of losing our memory.One possible reason why women have better memories than men is thatA.they have a wider range of interestsB.they are more reliant on the environmentC.they have an unusual power of focusing their attentionD.they are more interested in what's happening around them??One possible reason why women have better memories than men is that??A.they have a wider range of interestsB.they are more reliant on the environmentC.they have an unusual power of focusing their attentionD.they are more interested in what's happening around them请帮忙给出每个问题的正确答案和分析，谢谢！
