分析 --如果他再次在月考中失败怎么办?
--我不知道,他会灰心而沦落为不上学了吗?

解答 答案:D.
第一句话的if he failed in the next monthly examination again?是对将来的虚拟条件句,下文是对将来虚拟的主句,用would do,第二空be reduced to doing"沦落为做…",to是介词,后面接动名词,not放在动名词前面,所以选D.

点评 将来的虚拟条件句表示与将来事实相反:
从句:Were to/should+动词原形   主句:Would/could/should/might+动词原形

12.My daughter and I collected the empty cans and bottles in our home.this morning,We had 6 full garbage bags later so I knew we would be spending a bit more of time at the recycling center.When we got there,a man and his kids were also doing the morning recycling and were using two of the four machines to recycle their plastic and cans.Luckily,we were able to use the 2 remaining machines.
     Of course,there were others that came,but when they saw the two,families with garbage bags full of recycled things,they quickly left.However,one woman came in with just 5 cans and looked as if she was in a hurry.So I stopped what I was doing and let her in to recycle her cans.Of course,she was grateful,and it felt good to let her go ahead of me.But that was not the whole story.
      My daughter and I continued to work through the bags,but the plastic recycling machine stopped working because it was full.My daughter was left with nothing to,do.The other family was still  using the other two plastic recycling machines,but it.seemed that they were almost done.I just told my daughter we would have to wait until they were done.But the man of the other family came through with another act of kindness.He offered to let us go ahead of him.I was really surprised,because we had more than 5 bottles,but he didn't seem to mind.I happily acceptedit.
      It was great to give and then to get an act of kindness in turn.It was small,I didn't expect it,but it surely brightened up my day.

8.Life in the Clear
Transparent animals let light pass through their bodies the same way light passes through a window.These animals typically live between the surface of the ocean and a depth of about 3,300feet-as far as most light can reach.Most of them are extremely delicate and can be damaged by a simple touch.Sonke Johnsen,a scientist in biology,says,"These animals live through their life alone.They never touch anything unless they're eating it,or unless something is eating them."
And they are as clear as glass.How does an animal become see-through?It's trickier than you might think.
The objects around you are visible because they interact with light.Light typically travels in a straight line.But some materials slow and scatter(散射) light,bouncing it away from its original path.Others absorb light,stopping it dead in its tracks.Both scattering and absorption make an object look different from other objects around it,so you can see it easily.
But a transparent object doesn't absorb or scatter light,at least not very much,Light can pass through it without bending or stopping.That means a transparent object doesn't look very different from the surrounding air or water.You don't see it----you see the things behind it.
To become transparent,an animal needs to keep its body from absorbing or scattering light.Living materials can stop light because they contain pigments(色素) that absorb specific colors of light.But a transparent animal doesn't have pigments,so its tissues won't absorb light.According to Johnsen,avoiding absorption is actually easy.The real challenge is preventing light from scattering.
Animals are built of many different materials----skin,fat,and more----and light moves through each at a different speed.Every time light moves into a material with a new speed,it bends and scatters.Transparent animals use different tricks to fight scattering.Some animals are simply very small or extremely flat.Without much tissue to scatter light,it is easier to be see-through.Others build a large,clear mass of non-living jelly-lie(果冻状的)material and spread themselves over it.
Larger transparent animals have the biggest challenge,because they have to make all the different tissues in their bodies slow down light exactly as much as water does.They need to look uniform.But how they're doing it is still unknown.One thing is clear for these larger animals,staying transparent is an active process.When they die,they turn a non-transparent milky white.

A.change the direction of light travel
B.gather materials to scatter light.
C.avoid the absorption of light
D.grow bigger to stop light.

A.move more slowly in deep water
B.stay see-through even after death

D.take effective action to reduce light spreading.
5.Now 16years old,Kelsey has her cow-Iris,a 6-year-old Jersey with a silky tan coat and soulful brown eyes.She also has established Fort Bantam Creamery,a one-cow dairy based on a self-designed and profitable cow-share program.
Kelsey's Fort Bantam Creamery customers purchase a share of Iris for 15,andthenpayafeetoKelsey(3.50per half gallon of milk) to board,care for and milk that share of the cow.At 3.50 per half gallon,Iris'milk is about double the cost of milk from grocery stores in the area,but no one is complaining.One of Iris'share holders drives more than 100 miles round trip to get the milk,on top of paying a 15dollars ferry toll.
Kelsey had her own ideas for Iris'care.She says she wanted her cow to be grass-fed because milk from grass-fed cows is higher in carotene(胡萝卜素)and vitamin E than milk from grain-fed cows.In part,that's because fresh grass has more of these nutrients than grain.Another factor behind the high nutrient content is that a grass-fed cow produces less milk than a grain-fed cow,and because any given cow has only a set amount of vitamins to transfer to her milk; the less milk she produces,the more vitamins are in each glass.
"One thing that people should know before they get a dairy cow,"Kelsey says,"is that they take a lot of your time."Kelsey milks Iris by hand twice a day,305days a year.When Kelsey started,she says,it took her about 45minutes to milk the cow; today,she gets the job done in less than half that time.Having a cow to milk every day also means little time off."If you do go on vacation,"Kelsey says,"you have to get someone to do the milking for you,which is not as easy as getting a neighbor to watch your dog or cat."When she goes away,Kelsey is fortunate to have a cheese-making friend,Charlene Osman,who gladly milks Iris in exchange for the milk.

64.Which of the following is TRUE according the passage?C
A.The nutrient content of milk has little to do with the cow's food.
B.Now Kelsey does the milking as skillfully as Charlene Osman.
C.Charlene Osman can gain the milk without paying Kelsey a fee
D.Jersey is a kid who wears a silk coat and has emotional eyes.
65.What does the underlined word"Shareholders"in Paragraph 2refer to?A
A.People who pay Kelsey for partial ownership of Iris
B.People who take care of Iris when Kelsey is away
C.People who transport milk products for Kelsey
D.People who govern Kelsey's sales of raw milk
66.Which of the following best describes Kelsey?A
A.Ambitious and committed
B.Generous and fortunate
C.Talented but indifferent
D.Wealthy but cold-hearted
67.Which of the following can be the best title for the text?B
A.A 16-Year-Old Has a Little Milk Cow
B.A 16-Year-Old Runs a One-Cow Dairy
C.A 16-Year-Old Feeds a Little Milk Cow.
