6.Once,an old and strange scientist Decided to use the cloning procedure to make(61)aclone of his boss's dog.He was working on the assumption that if he produced a clone of the dog,his boss(62)would approve(approve) his promotion.The man stirred his mixture(63)which/thatcontained the dog's hair.If his colleagues heard about his efforts they would be bound(64)to stop(stop) him.They could never resist an opportunity of saying that he was too old to work in a cloning laboratory.He did make mistakes(65)fromtime to time,but only last week he succeeded in restoring a(66)dead(die) mouse to life as a clone.So,why not clone a dog?As he was thinking,the mixture thickened.He stared impatiently at it,(67)waiting(wait) for the shape of the animal that would(68)shortly(short) emerge.Gradually the cells began to form.A creature began to grow and develop(68)claws(claw) and feathers!The scientist screamed and fled from the room as any possibility of promotion(70)disappeared(disappear) in that instant.He had not brought back a dog but produced a monster!

分析 本文向我们讲述了曾经,一位又老又古怪的科学家决定用克隆程序克隆他的老板的狗,他在设想,如果他克隆出一只狗,老板就会批准他的晋升.最后科学家没能克隆出狗却制造了一个怪物.

解答 61.a,考查冠词,clone是可数名词,表示泛指,前使用不定冠词a.             
62.would approve,考查时态,if引导的条件状语从句,主句使用一般将来时,从句使用一般现在时,该题从句是一般过去时,主句应使用过去将来时would do 的形式.      
63.which/that,考查定语从句,句子先行词是mixture,引导定语从句使用which/that.      
64.to stop,考查不定式,be bound to do sth."一定会做某事".           
65.from,考查介词,from time to time"时不时地".  
66.dead,考查形容词,此处应使用形容词修饰后面的名词mouse.       
67.waiting,考查非谓语动词,wait 的逻辑主语是he,构成主动的关系,因此使用现在分词充当非谓语.                 
68.shortly,考查副词,此处应使用副词修饰谓语动词would emerge.             
69.claws,考查名词,此处应使用名词的复数形式claws.             
70.disappeared,考查时态,短文描述的是过去的事件,因此使用一般过去时disappeared.

点评 对于语法填空这类题,一是懂得分析句子结构,二是知道充当各个句子成分的词类或词性,从语法上确定答案,当然,对于某些固定搭配也要牢记,在平时的学习中要多积累这些词汇或短语,对于句子使用的时态语态也要通过语境进行确定.

17.There has been a recent trend in the food service industry toward lower fat content and(61)less(little) salt.This trend,which was started by the medical community(医学界)as a method of fighting heart disease,has had some unintended side(62)effects(effect) such as overweight and heart
disease-the very thing the medical community was trying to fight.
Fat and salt are very important parts of a diet.They are(63)required( require) to process the food
that we eat,to recover from injury and for several other bodily functions.When fat and salt(64)are removed
(remove) from food,the food tastes as if is missing something.As a result,people will eat more food to try to make up for that something missing.Even (65)worse(bad),the amount of fast food that people eat (66)goes(go) up.Fast food(67)is(be) full of fat and salt; by eating (68)more (much) fast food people will get more salt and fat than they need in their diet.
Having enough fat and salt in your meals will reduce the urge to snack(吃点心) between meals and
will improve the taste of your food.However,be (69)careful(care) not to go to extremes.Like anything,it is possible to have too much of both,which is not good for the (70)health(healthy).
1.How to Draw a Mind MapMind mapping relates to writing down a central idea and thinking up new and relevant ideas which radiate out from the center.
Look for relationships
Use lines,colors,arrows,branches or other ways of showing connections between ideas on your mind map.(36)G.Personalizing the map with your own symbols and designs will assist in your recall and understanding.
(37)D
All of these things promote linear(线性的)thinking while the idea of mind mapping is to think creatively and in  anon-linear manner.There will be plenty of time for polishing the information later on.But at this stage,the most important thing is to get every possibility into the mind map that may be the key to your knowledge of a topic.
Write down key ideas
Some students find that using capital letters encourages them to get down only the key points.(38)A.You may,however,wish to write down some explanatory notes in lower cases.Some students do this when they revisit the mind map at a later date while others write such things as assessment criteria in this way.
Put the main idea in the center
Most students find it useful to turn their page on the side and do a mind map in"landscape"style.They put the main idea or topic in the middle of the page.(39)E.
Leave lots of space
(40)F.After the initial drawing of the mind map you may wish to highlight things,add related information or questions right up.

A.Capitals are also easier to read in a diagram
B.Make a list all your ideas you need
C.This helps them assess the related information
D.Draw quickly without pausing,judging or editing
E.This gives the maximum space for other ideas to radiate
F.Some most useful mind maps are those adds over a period of time
G.These relationships may be important in understanding new information.
18.There are several ways from which to choose for you to keep your kids safe in your neighborhood.But the first step to keep your child safe in your neighborhood is to know your neighbors.
Knowing your neighbors can save you a lot of worry.It lets you know that the car that has just driven down the street belongs to"the yellow house on the corner",or the truck that has just driven by the playground looks unfamiliar,but the guy in the passenger seat resides two doors down.It's these simple things that keep you from going out of your mind whenever you see someone driving by where children are playing.
But you shouldn't just know what they look like.The next step is to know them well.What do they do?How do they act?You might be OK with them driving by the playground since they live in the neighborhood,but are you OK with them being on the playground?Knowing your neighbors solves several things.First you find out what kind of people they are.This helps you know if you should let your child go out in an area where they gather.Let us face it:you do not want your child to play around people or people's children that curse (咒骂) or hit each other.Sometimes you have to protect your child against your own neighbors.
Knowing them also makes them know you.Being neighbors is an interesting thing.You might not like them or have the same views as them,but we all usually protect those that we consider our own.If you know your neighbors,they know you.They are more likely to look after the child of the nice lady down the street in the brick (砖) house,than the people,in the house on the corner,who no one ever sees.

15.Any car accident is frightening,but an accident in which your vehicle is thrown into the water,with you trapped inside,is absolutely terrifying.(36)DHowever,most deaths result from panic,without a plan or understanding what is happening to the car in the water.By adopting a brace(支撑) position,acting decisively and getting out fast,you can save yourself from a sinking vehicle.
Brace yourself for impact (撞击力).As soon as you're aware that you're going off the road and into a body of water,adopt a brace position.The impact could set off the airbag system in your vehicle,so you should place both hands on the steering wheel in the"ten and two"position.
Undo your seatbelt.(37)FUnbuckle the children,starting with the oldest first.Forget the cell phone call.Your car isn't going to wait for you to make the call.
(38)ALeave the door alone at this stage and concentrate on the window.A car's electrical system should work for up to three minutes in water,so try the method of opening it electronically first.Many people don't think about the window as an escape option either because of panic or misinformation about doors and sinking.
Break the window.If you aren't able to open the window,or it only opens halfway,you'll need to break it with an object or your foot.It may feel counter-intuitive (有悖常理的) to let water into the car.
(39)G
Escape when the car has equalized.If it has reached the dramatic stage where the car cabin has been filled with water and it has become balanced,you must move quickly and effectively to ensure your survival. (40)CWhile there is still air in the car,take slow,deep breaths and focus on what you're doing.

A.Open the window as soon as you hit the water.
B.Surviving a sinking car is not as difficult as you think.
C.It takes 60 to 120 seconds for a car to fill up with water usually.
D.Such accidents are particularly dangerous to the risk of drowning.
E.In conclusion,if you know what to do in the water,you will be safe.
F.This is the first thing to attend to,yet it often gets forgotten in the panic.
G.But the sooner the window is open,the sooner you can escape directly through it.
16.1A narrow escape from death can actually improve a person's view on life.That,at least,was one of the major findings of a study of some 200 people who come close to dying.Some had come through heart attack; some had fallen and come close to drowning or survived a terrible car wreck,yet despite the variety of circumstances,they reported strikingly similar reactions to their experiences.
Perhaps most surprisingly,many said they were less frightened of death now than they were before.Like most people,before their near-death incidents,many had thought death would be painful,the ultimate horror-but they didn't find it was.
Surviving a nearly fatal experience also gave many people a sense of invulnerability(不会受伤害)that made them feel special and even religious.Several believed they had been saved because they were to fulfill some special mission in the remainder of their lives.
Perhaps not so surprisingly,these survivors also reported an increased enthusiasm for life and a determination to enjoy life more.
A few of the survivors did report negative reactions to their experience.A dozen said they felt more vulnerable(脆弱的),and some even felt a sense of helplessness and a loss of control over their lives.Some had become phobic about activities associated with the accident; for example,several said they could no longer swim for fear of drowning.
Yet most of those interviewees said they came away with a strong sense of renewal or rebirth.In studying their reactions researchers have concluded that these people have come to understand the relationship of life and death better and more intimately than most of us,they have come to understand how life is actually defined by death.Life is given meaning by the fact that it will end someday.
