5."Have you noticed it?It is quite a time that these blooms have lasted this year,"my wife said.
"I didn't really think about it,yet you've said it.(36)CI love lilacs (丁香),they come and go so fast."I said.
       It has been unbelievably(37)Bthis year here in the backyard of my house.Our lilac tree has produced the most blooms I have   38C  seen.The pleasant smell is so wonderful(39)CI spend a lot of time just standing by the window,(40)Ait all in.
      Quite a few branches of the tree are hollow and cracked,leaving me to believe it has(41)Dmany springs.A few winters ago one of the biggest branches crashed to the ground(42)Bthe weight of melting snow.It broke my heart.I had assumed I wasn't(43)A much from the old thing this year.(44)Cit is magnificent!
       Since we have been experiencing so much rain lately,the flowers have become (45)A.The once tall branches seem to be under a lot of pressure.There are big(46)A because the branches are lower.
         (47)D,today I noticed the first bunch of flowers turning brown.It won't be long (48)Cthey are all gone.The flowers will eventually all fade away no matter how beautifully they (49)A before me.But I have learned something from them.
Some people are like(50)Bflowers.They come into our lives ever so   51D,share with us what they have in them and (52)Cthe pleasant smell that remains deep in our minds.They(53)Dour days by just having us contact with them even if for a moment.In the(54)C,darkest days of the winter of my life,the memory of them will get me through it all and bring a smile to my face and I will have"(55)Aforever in my heart."

4.People know that outdoor air pollution can damage their health,but many don't realize that indoor air pollution can also have significant health effects.Studies indicate that indoor levels of pollutants may be 2~5 times,and(36)Cmore than 100 times,higher than outdoor levels.These levels of indoor air pollutants may be of particular(37)Abecause most people(38)Cabout 90%of their time indoors.
   Immediate effects (39)Bup after a single exposure or repeated exposures.These include irritation(刺激) of the eyes,nose,throat and headaches.Such immediate effects are usually (40)Dand treatable.Sometimes the treatment is simply eliminating the person's exposure to the source of the pollution,(41)Ait can be identified.Symptoms of some diseases may also show up soon after exposure to some indoor air pollutants.
   Certain immediate effects are(42)Bto those from colds or other diseases,so it is often difficult to determine if the symptoms are a(n)(43)Dof exposure to indoor air pollution.For this reason,it is important to(44)Cattention to the time and place the (45)Coccur.If the symptoms(46)Bor go away when a person is away from the home and return when the person returns,(47)Dshould be made to identify indoor air sources that may be possible causes.Some effects may be made worse (48)Aan inadequate supply of outdoor air or from the heating,cooling,or humidity conditions in the home.

3.When I was in junior high school,darkness began filling my mind.I don't know the day or the reason why it began.All I know is that I started feeling hopeless and worthless.I hid in my room,(32)staring(stare) out of the window,thinking about all my failures.I even questioned   (33)whether/ifbeing alive was worthwhile.My dark mood wasn't constant.It would fade at times,but it always returned.
It was my parents that helped me identify the shadow (34)that/whichhung over my life-depression.Depression is (35)amental illness that drains your energy and prevents you from enjoying life.It can keep you from succeeding at school or work or from connecting with others.At its (36)worst(bad),depression can even lead to suicide.
When your mood is dark,how do you know whether you are depressed or just sad?Think about how long the feelings (37)have lasted(last).If they have persisted for weeks or months,get help.
No one (38)canface depression alone.If you're depressed,find someone-a friend,parent,teacher or pastor-and tell them your feelings.Consider seeing a doctor or psychologist,if they are getting worse.
When I was depressed,I was (39)embarrassed(embarrass) to tell anyone.I didn't want to seem weak or needy.But when I told my friends,they supported and encouraged me.
In fact,(40)although/thoughdepression affects many people worldwide,treatments are available and can bring hope and joy back into their life.
1.A few days ago I discovered that one of my chairs had a broken leg.I didn't think there would be any difficulty in getting it (11)D,as there are a lot of antique (古董) shops near my home.(12)A I left home one morning carrying the chair with me.I went into the first (13)B expecting a friendly reception.I was quite (14)D.The man wouldn't even look at my chair.
The second shop,though slightly more (15)C,was just the same,and the third and the fourth--so I decided that my (16)A must be wrong.
I entered the fifth shop with a(n)(17)C in my mind.I placed the chair on the floor and said to the shopkeeper,"Would you like to (18)B a chair?"He looked it over (19)D and said:"Yes,not a bad chair.How much do you want for it,Sir?"
"Twenty pounds,"I said."OK,"he said."‘I'll give you twenty pounds.""It's got a slightly broken leg,"I said."Yes,I saw that.It's (20)A."
Everything was going according to the plan and I was getting(21)B."What will you do with it?"I asked."Oh,it will be easy to sell (22)C the repair is done.""I'll buy it,"I said."What do you mean?You've just (23)A it to me,"he said."Yes,I know but I've (24)B my mind.I am sorry.I'll give you twenty-seven pounds for it.""You must be (25)D,"he said.Then,(26)C the penny dropped."I know what you want.You want me to repair your chair."
"You're (27)D,"I said."And what would you have done if I had walked in and said,‘Would you mend this chair for me?'""I wouldn't have (28)D to do it,"he said."We don't do repairs,not enough money in it and too much (29)A.But I'll mend this for you.Shall we say for five pounds?"

12.With only about 1,000pandas left in the world,China is desperately trying to clone the animal and save the endangered species.That's a move similar to what the Texas A&M University researchers have been undertaking for the past five years in a project called"Noah's Ark".
Noah's Ark is aimed at collecting eggs,embryos (胚胎),semen and DNA of endangered animals and storing them in liquid nitrogen.If certain species should become extinct,Dr Duane Kraemer,a professor in Texas A&M's College of Veterinary Medicine,says there would be enough of the basic building blocks to reintroduce the species in the future.
It is estimated that as many as 2,000species of mammals,birds and reptiles will become extinct in over 100years.The panda,native only to China,is in danger of becoming extinct in the next 25years.
This week,Chinese scientists said they grew an embryo by introducing cells from a dead female panda into the egg cells of a Japanese white rabbit.They are now trying to implant the embryo into a host animal.
The entire procedure could take from three to five years to complete.
"The nuclear transfer (核子移植) of one species to another is not easy,and the lack of available panda eggs could be a major problem,"Kraemer believes.
"They will probably have to do several hundred transfers to result in one pregnancy (怀孕).It takes a long time and it's difficult,but this could be groundbreaking science if it works.They are certainly not putting any live pandas at risk,so it is worth the effort,"adds Kraemer,who is one of the leaders of the Project at Texas A&M,the firstever attempt at cloning a dog.
"They are trying to do something that's never been done,and this is very similar to our work in Noah's Ark.We're both trying to save animals that face extinction.I certainly appreciate their effort and there's a lot we can learn from what they are attempting to do.It's a research that is very much needed."
28.The aim of"Noah's Ark"project is toB.
A.make efforts to clone the endangered pandas
B.save endangered animals from dying out
C.collect DNA of endangered animals to study
D.transfer the nuclear of one animal to another
29.According to Prof.Kraemer,the major problem in cloning pandas would be the lack ofA.
A.available panda eggs  
B.host animals

11.Four Steps to Begin Your Path to Greatness
Feeling stuck is quite common.Many times,we have thoughts and dreams of what we want in life.(36)F Our thinking pattern holds us back from going forward.The good news is,at any moment in tie,we have the ability to start taking action toward creating the life we want.Here are four steps to get started:
1.Celebrate Your Success.
Write down all the successes you've already achieved and all the awesomeness that you are today.(37)EAnd once you're in that positive routine with your thoughts,it will lead you to make better choices and take better actions toward your greatness.
2.Create Your True Vision.
Many times we live based on others'expectations or we stay stuck in a particular place because it's our safety zone.Own your path.It can be hard to do,but allow yourself to get out of your head(or stop listening to what others want for you)and focus on your heart and what it's telling you.(38)G
3.(39)B
If you want to start going to the gym,going 5days a week right away is extreme,and setting yourself up by biting more than you can chew typically doesn't result in success,but failure.Instead,start slow and go once or twice a week.After you do that for a while and get into a nice routine,up it to more days.Over time,you will build toward your goal by taking realistic,smaller steps to get there.
4.Have the Right Support.
(40)A Find the right support to cheer you on in the process.It could be a friend,a family member,or significant other who you trust.Whoever it may be,having someone on your journey will be just what you need to keep you on track and celebrate with you as you work toward the life you dream of.
A.Don't do it alone.
B.Be realistic about your goals.
C.Be kind to yourself and accept the moment.
D.Your failure can lead you to another success.
E.This practice will direct your thinking to a positive place.
F.Sadly,they only stay as thoughts and dreams inside of us.
G.Look within yourself deeply and decide what you want and what's true for you.
10.Would it surprise you to learn that,like animals,trees communicate with each other and pass on their wealth to the next generation?
UBC Professor Simard explains how trees are much more complex than most of us ever imagined.Although Charles Darwin thought that trees are competing for survival of the fittest,Simard shows just how wrong he was.In fact,the opposite is true:trees survive through their co-operation and support,passing around necessary nutrition"depending on who needs it".
Nitrogen(氮) and carbon are shared through miles of underground fungi(真菌)networks,making sure that all trees in the forest ecological system give and receive just the right amount to keep them all healthy.This hidden system works in a very similar way to the networks of neurons(神经元)in our brains,and when one tree is destroyed,it affects all.
Simard talks about"mother trees",usually the largest and oldest plants on which all other trees depend.She explains how dying trees pass on the wealth to the next generation,transporting important minerals to young trees so they may continue to grow.When humans cut down"mother trees"with no awareness of these highly complex"tree societies"or the networks on which they feed,we are reducing the chances of survival for the entire forest.
"We didn't take any notice of it."Simard says sadly."Dying trees move nutrition into the young trees before dying,but we never give them a chance."If we could put across the message to the forestry industry,we could make a huge difference towards our environmental protection efforts for the future.
