题目内容

9.[1]A flood is the overflow of a huge amount of water onto normally dry land.Flooding occurs when the overflowing water submerges (淹没) land,and it causes a lot of problems.It is a cruel and violent expression of water.
[2]Floods are often deadly and damaging.They kill lots of people,damage houses and crops,and cause extensive destruction.In broader terms,floods are of two types:natural floods and catastrophic floods.Natural floods are the floods that are caused naturally by the overflow of a huge volume of water,from rivers,lakes,oceans,or by heavy rain or downpours,hurricanes,and so on.Catastrophic floods are floods that are caused by some significant (重大的) or unexpected events,for instance,dam breakages.
[3]Heavy rainfall is one of the major causes of floods.The level of water in rivers or lakes rises due to heavy rainfall.When the level of water rises above the river banks or dam,the water starts overflowing,which causes floods.Floods occur more in the regions that ____________.
[4]Floods are also caused due to heavy snow melting.Global temperatures are rising due to global warming.The rising temperatures are making the snow caps melt faster.Continuous and fast melting snow raises the level of water in the oceans,which consequently raises the level of water in rivers,and when the level of water in rivers rises above the river banks,it causes floods.
[5]Generally,floods occur more in low-lying areas or areas below sea level.One of the main reasons is that rivers flow slowly in these areas.′The volume of water increases in low-lying areas.When the level of water rises in these regions,it causes floods.
[6]Sometimes floods are caused due to poor dams that cannot hold great volume of water.Therefore,there are always different causes of floods.However,floods caused by humans can be avoided.Humans should let the nature go its own way.

77  When the overflowing water submerges land.细节题.根据第一段"Flooding occurs when the overflowing water submerges (淹没) land"可知,当过多的水淹没地面时,就会产生洪水灾害.故填When the overflowing water submerges land..
78  Some significant or unexpected events,like dam breakages.细节题.:根据第二段"Catastrophic floods are floods that are caused by some significant (重大的) or unexpected events,for instance,dam breakages."可知,灾害性洪水是由一些重大或突发事件引起的洪水.故填Some significant or unexpected events,like dam breakages..
79  get heavy rainfall细节题.根据第三段"Heavy rainfall is one of the major causes of floods."可知,本段讲的是大雨,所填的与大雨有关,故填get heavy rainfall.

7.When a baby is seven months old,he or she can already feel,hear,taste,smell and see.As a new mother,you should know that your child is ready to learn about the world from birth.
Touch.One of the most important means of communicating a mother has with her baby is touch.Babies enjoy gentle touch and rhythmic(有节奏的) movement.While inside the mother,the baby is used to being rocked by the mother's movements.After birth,the same rocking movements comfort him or her.Crying babies often become quiet by being put close to the mother's body and gently rocked.Even the most common activities-feeding and bathing the baby,or walking with the baby in your arms-improve the baby's sense of touch and movement.
Smell and Taste.Even at birth,babies show that they can tell apart different kinds of smells by turning away from unpleasant ones.They quickly learn to recognize familiar smells,especially their mothers'.Although their taste organs aren't completely developed,they can tell sweet from sour and much prefer the former.
Hearing.A baby listens to your voice,your heartbeat,breathing and so on.When his or her head is pressed against your chest,those familiar sounds are comforting,and many babies fall asleep in this position.You may notice that high-pitched(声调高的) voices are more pleasant to babies,so men should raise the pitch of their voices when speaking to them.As a baby gains more control over his or her head movements,it becomes clear that he or she can correctly find the location of a sound source.Loud,sharp noises often upset babies,while soft,rhythmic sounds calm them down.Music boxes,toys that make pleasant sounds and soft music stimulate(激发)the babies'sense of hearing.

C.They would be upset by a toy that makes sharp noises.
D.They're not sure of where sounds are coming from

20.Reading to oneself is a modern activity that was almost unknown to the scholars of the classical and medieval(中世纪的)worlds,while during the fifteenth century the term"reading"undoubtedly meant reading aloud.Only during nineteenth century did silent reading become common-place.
One should be careful,however,of assuming that silent reading came about simply because reading aloud is a distraction to others.Examination of factors related to the historical development of silent reading reveals that it became the usual mode of reading for most adult reading tasks mainly because the tasks themselves changed in character.
The last century saw a steady gradual increase in literacy,and thus in the number of readers.As readers increased,so the number of potential listeners declined,and thus there was some reduction in the need to read aloud.As reading for the benefit of listeners grew less common,so came the flourishing(繁荣) of reading as a private activity in such public places as libraries,railway carriages and offices,where reading aloud would cause distraction to other readers.
Towards the end of the century there was still considerable argument over whether books should be used for information or treated respectfully,and over whether the reading of material such as newspapers was in some way mentally weakening.Indeed this argument remains with us still in education.However,whatever its virtues,the old shared literacy culture had gone and was replaced by the printed mass media on the one hand and by books and periodicals(期刊)for a specialized readership on the other.
By the end of the century students were being recommended to adopt attitudes to books and to use skills in reading them which were inappropriate,if not impossible,for the oral reader.The social,cultural,and technological changes in the century had greatly altered what the term"reading"implied.

14.[1]As is known,it is important to help your children gain key information from textbooks or understand what they read,especially as they get older.Here are the ways to improve their reading comprehension.
[2]Have them read aloud.This forces them to go slower,which gives them more time to process what they read.Besides,they are not only seeing the words,they are hearing them,too.
[3]Provide the right kinds of books. Make sure your children get lots of practice reading book that aren't too difficult.They should recognize at least 90 percent of the words without any help.Stopping any more often than that to figure out a word makes it tough for them to focus on the overall meaning of the story.
[4]Reread to build fluency.To gain meaning from text,your children need to read quickly and smoothly-a skill known as fluency.Rereading familiar,simple books gives your children practice at decoding(解译) words quickly,so they'll become more fluent.
[5]Talk to the teacher.If your children are struggling with comprehension,they may need more help with their reading-for example,they can turn to the teacher to build their vocabulary or practice phonics skills.
[6]Supplement(补充) class reading. If the class is studying a particular theme(主题),look for easy-to-read books or magazines on the topic.Some prior knowledge will make their way through tougher classroom texts.
[7]Talk about what they are reading. This"verbal processing"helps them remember and think through the themes of the book.Ask questions before,________,for example:
Before:"What interests you in this book?What doesn't?"
During:"What's going on in the book?Is it turning out the way you thought it would?"
After:"Can you summarize the book?What did you like about it?"
