9．Astronauts in space may suffer motion sickness，muscle loss，tiredness and bone loss due to low or zero gravity and weightlessness．But scientists at the University of Delaware are experimenting with little worms to better understand how space travel affects astronauts．
The millimeter-long worm，called C．elegans，is often used in medical studies because its life is only about two weeks long．Seventy percent of its DNA is the same as human DNA．
Chandran Sabanayagam，a scientist with the University of Delaware，built a microgravity simulator（模拟器）to test how C．elegans would perform in the actual zero gravity of space．
Scientists use a computer to watch the worms as they constantly turn over the simulator．The computer shows the worms as they would look under a microscope．Mr．Sabanayagam says the worms turn around and around in the simulator for about one week before they take them out，looking for changes in the worms'epigenome．The epigenome are chemical markers that relate to microgravity and that tell the DNA in the cells how to perform．They can be changed by the environment．And those changes pass from one generation to the next．
"When the worms are in microgravity environment some epigenomic marks remain even when we put it back into normal ground conditions．So its offspring（后代）keeps this epigenomic memory of the parents'microgravity environment．"
The information gathered suggests that the epigenomic marks appear during the early part of a worm's life．Mr．Sabanayagam says identifying epigenomic marks is important for human studies in the future．
Mr．Sabanayagam thinks scientists can find genes（基因）in the human genome（基因组）similar to those in the worms that responded to microgravity．He says scientists could possibly observe those genes closely when astronauts travel in space．
Chandran Sabanayagam expects C．elegans to visit the International Space Station within two years．He hopes information gathered from the worm studies can be used to develop simple，low-cost and quick tests to measure an astronaut's health．
72．What is the purpose of the research？A
A．To seek a way to solve astronauts'healthy problems resulting from weightlessness．
B．To produce medicines from the C．elegans DNA to prevent astronauts from diseases．
C．To see how much similar the C．elegans DNA is to that of human．
D．To prove the practicability of taking the C．elegans to the outer space．
73．What does the underlined word"They"in the paragraph 4refer to？C
A．Scientists．
B．The worms．
C．The epigenome．
D．Astronauts．
74．What happens to the worms during the experiment？B
A．They are put under a microscope and turned around and around．
B．There are some changes in their epigenome with the microgravity environment．
C．Some of them can't adjust to normal ground conditions after the experiment．
D．Chemical markers in them have changed so that their DNA can't perform well．
75．According to the passage，scientistsB．
A．are having difficulties in identifying epigenomic marks in human genes
B．are still on the way to finding human genes that respond to microgravity
C．have sent C．elegans to the International Space Station for the experiment
D．believe using the worms to measure an astronaut's health is costly and quick．

7．An old Grandfather said to his grandson，who came to him with anger at a friend who had done him an injustice，"Let me tell you a（n）（21）B"
"I too，at times，have felt great（22）Afor those who have taken so much，with no（23）Dfor what they do．But hate（24）Cyou out，and does not hurt your enemy．It's like taking poison and wishing your enemy would die．I have（25）Bthese feelings many times．"
"It is as if there are tw（26）Cinside me； one is good and does no harm．He lives （27）Aall around him and does not take offense when no offense was intended．He will only（28）Cwhen it is right to do so，and in the right way．"
"But…the other wolf…ah!The littlest thing will send him into a fit of（29）B．He fights everyone，all of the time，for no（30）D．He cannot think because his anger and hate are so great．It is（31）Aanger，for his anger will change nothing．"
"Sometimes it is（32）C to live with these two wolves inside me，for both of them try to （33）Bmy spirit．"
With great（34）Dthe boy looked intently（专注地）into his Grandfather's eyes asked，"Which one wins，Grandfather？"
The Grandfather smiled and quietly said，"The one I （35）A"
You have two sets of feelings； positive feelings and negative feelings．And you know the （36）Bbetween the two because one makes you feel good，and the other makes you feel had．You should always remember that it is （37）Dto feel good while having（38）Cthoughts．
When you are feeling good，you must be thinking something good．So you are sending out a powerful frequency that is（39）Aback to you more good things that will make you feel good．（40）Bthose moments when you are feeling good，and milk them．Be aware that as you are feeling good，you are powerfully attracting more good things to you．

14．A woman shows us that it's never too late to get your degree．Johnson，a 79-year-old grandmother，is graduating from the University of Maryland University College（UMUC） with a bachelor's degree in Human Resource Management．
Her journey towards her college degree actually began back in 1962when she attended Morgan State University in Baltimore．She went there for 2 years，but put her studies on hold to start a family with her husband James．They ended up having three sons together-all of them college graduates．"After they graduated from college，my oldest son decided to give me a computer，"Johnson said．"Well，it's time for me to go back and get my degree．"
After finishing her job in the government in 2009，she was admitted to the University of Maryland University College in their online program．Her thought to return to school came after seeing her friends and old classmates at Morgan State．"They stayed there and completed their course there and that encouraged me，"Johnson said．"I said I want to go back and do the same thing．"
There were some problems Johnson had to deal with in her new path in life．She would not be able to transfer the credits（转学分） she earned from Morgan State over to UMUC．Even though she was given a computer，she was not good at it．But that did not stop her from reaching her goal．
For anyone else who wanted to go back to college after long absence，Johnson would encourage it．"You might need a teacher at times，"she said．"I think it's a very good idea．That's what you want to do．That's what I wanted to do．"What's next for this grandmother？She's not quite sure．However，UMUC has advised her to get her master's degree．

4．Two disabled Chinese citizens who have planted trees （61）voluntarily（voluntary） in Northern China have been voted （投票） by Chinese netizens as their inspiring heroes．
The vote（62）has been organized（organize） by Xinhua News Agency since 2011 to inspire moral strength in the public by highlighting the good deeds of ordinary people．The event is the first of its kind（63）to find（find） heroes among grassroots people．
Jia Wenqi and Jia Haixia，both of （64）whomare aged over 50，have arm and sight disabilities．Disabled   （65）as/thoughthey are，they have planted over 10，000 trees in Jingxing County over the past 13 years，preventing their village from flooding and （66）improving（improve） the environmental surroundings．
"I am his hands； he is my eyes，"says Haixia．"We are good partners．"
Fully （67）devoted（devote） to protecting the environment，they have turned the wasteland into a green one，which attracts（68）alarge number of birds．Planting trees has become an important part of their life．
Despite their disabilities，they form a great team that makes a huge（69）diffference（different）．They deserve to be called eco-heroes （70）fortheir unusual effort and amazing deed!
11．Wasting food has become a big problem in the developed world．While some people there throw away unwanted food，people in other（61）parts （part） of the world face food shortages．It's an （62）astonishing  （astonish） fact that a third of the world's food is wasted each year，which is enough （63）to feed  （feed） a billion hungry people．
Most of the wasted food （64）is burried  （bury） in the landfill sites．（65）Unluckily （unlucky），this causes greenhouse gases which eventually lead to global warming and climate change．
In Denmark，a woman called Selina Juul has been working hard to deal with （66）the  problem．She thinks people shouldn't waste food，（67）however  rich they are．She persuaded some supermarkets to stop（68）selling  （sell） their items （物品） in quantity so that people bought only what they needed．Also，she produced a leftovers cookbook and set up an education program in schools，（69）where  food waste was rather common．Now the effects are quite noticeable．
Clearly，we need to think （70）twice  （two） when we put something in our shopping basket，and we should make the most of the food we have-use up our leftovers or even share our extra food with our friends and neighbors．
