tell him how sorry I am for what I said.”可知，母亲想起了以前圣诞节的事，对自己所做的事感到难过，因此无法入眠，故B项正确。【答案】B4What is likely to be described in the next paragraph?AHow they would celebrate the Christmas.BHow the authors father supported the family.CWhat happened to the authors parents in the past.DThe reason for the authors parents divorce.【解析】根据最后一段母亲所说的话“That time and that Christmas have been a burden on my heart for twentyfive years.I wish your dad were here so I could tell him how sorry I am for what I said”可推知，母亲想起了以前圣诞节的事，对自己所做的事感到难过；据此可以判断，下文将叙述发生在作者父母身上的故事，故C项正确。【答案】CBSleep scientist YingHui Fu at the University of California, San Francisco, says “We do not know why some humans need more sleep；why some humans need less sleep；why, when we do not sleep, we do not function well.We just do not know much about sleep at all.” But scientists now know: A team led by Professor Fu has reported the first genetic link to how much sleep we need.The team was looking for a natural clock in the body that controls sleep and wakefulness.What they found was a genetic abnormality(反常)People who have this mutation(突变) need less sleep than others.But keep in mind that the scientists say this mutated gene may be rare.The study involved two members of an extended family.They did fine on just six hours of sleep a day.Studies have shown that over time, most humans need eight to eight and a half hours of sleep for the best health.To test their theories, the scientists genetically engineered the mutation in mice.The mice with the mutation needed less sleep than normal mice.They were also more active even after being kept awake.The researchers will continue to study the mice to test whether the gene is related to other medical conditions.And they will study whether it is involved in controlling sleep quantity alone, or also what scientists call the “wakefulnessbehavioral drive.” This drive is important for getting food, shelter and mates.How you sleep can be as important as how much you sleepespecially for newborn babies.The study found that more than onethird of the pictures in womens magazines showed babies in unsafe sleep positions.They showed babies sleeping on their sides or stomachs.The academy says babies should sleep on their backs.It says they should be placed on a separate sleep surface from their parents, without blankets, pillows or other soft bedding.【语篇解读】人们为什么需要睡眠？睡眠和人体的什么有关呢？本文就这个问题进行了最新的报道，报道了睡眠时间和基因突变有着一定的关系。5What sleep scientist YingHui Fu says at the beginning shows_.Arare scientists would like to do sleep researchBsleep research is

different from the regular English classes we were familiar to, for we had no textbooks，no blackboard or no fixed seats.Gathering at the entrance of the station，we told to collect as many English words and sentences as possible here.Curious and excited，we walked around the station and looked everywhere, search for any information in English.Whenever an English word comes into sight，the class would burst into the cheers as if we had discovered a new world.With the Chinese translation and vividly pictures，we could figure out its meaning with ease.Now，this unforgettable lesson still encourages me to be an active learner where I go.【答案】One year ago，I had a special English lesson at a railway station.It was quite different from the regular English classes we were familiar ，for we
