Should the color be white or black? Or perhaps navy blue! Well, choosing the right graduation dress for middle school students can be a little difficult at times. Here are some ideas for graduation dress for middle school students.
For many students, middle school graduation marks a big change in their lives. This is a step that takes students away from junior high school but towards the elementary level before senior high school. Compared to elementary (初级的) school, middle school means more lessons and more classes, but of course, students can also see it as an opportunity to make new friends.
Well, it is no wonder that the graduation day of a middle school is often planned formally. Although this occasion is not considered to be really formal like a high school graduation, it is still celebrated in many ways. Besides, it is also considered to be a very important part of someone"s life.
Many schools often have middle school graduation parties. Well, the question that often arises in the minds of young students is about the right graduation dress for themselves. Long flowing dress with caps are commonly seen. Students should always stick to a common graduation dress that creates uniformity (统一) among all. The dress can be royal blue, black or even golden. If they seem too formal for the party, you can even plan for a common color for all the students. For example, white shirts with black pants or skirts can serve the needs of such a special occasion.
Whether the graduation party is simple or great, the graduation dress for middle school students should be planned accordingly. The main idea would be to accept the success of the students and celebrate with family and friends.

Moss(藓类植物) found buried beneath the Teardrop glacier(冰川) on Ellesmere Island in Canada has been brought back to life. Findings suggest that these plants could help repopulate regions exposed by melting ice caps. Plants that were buried beneath thick ice in Canada more than 400 years ago and were thought to have frozen to death have been brought back to life by Canadian scientists.
Samples of the moss plant, covered by the glacier during the Little Ice Age of 1550 to 1850 AD, were replanted in a lab at the University of Alberta and grew new stems(茎). Researchers now think these findings can give indication as to how regions can recover as the ice covering them melts.
Biologist Dr. Catherine La Farge and her team at the University of Alberta were exploring the region around the Teardrop glacier on Ellesmere Island. Ice on Ellesmere Island region has been melting at around four meters each year for the past nine years. This means that many areas of land that were previously covered by ice have since been exposed. Many ecosystems that were thought to have been destroyed during the Little Ice Age between 1550 and 1850 AD can now be studied, including many species that have never been studied before.
While examining an exposed area of land, La Farge and her team discovered a small area of moss called Aulacomnium turgidum. It is a type of bryophyte(苔藓类植物) plant that mainly grows across Canada, the US and the Highlands of Scotland.
Dr La Farge noticed that the moss had small patches of green stems, suggesting it is either growing again or can be encouraged to repopulate. Dr La Farge told the BBC, “When we looked at the samples in detail and brought them to the lab, I could see some of the stems actually had new growth of green branches, suggesting that these plants are growing again, and that blew my mind. When we think of thick areas of ice covering the landscape, we’ve always thought that plants have to come from refugia(濒绝生物保护区), never considering that land plants come from underneath a glacier. It’s a whole world of what’s coming out from underneath the glacier that really needs to be studied. The ice is disappearing pretty fast. We really have not examined all the biological systems that exist in the world; we don’t know it all.”
Dr La Farge took samples of the moss and, using carbon-dating techniques, discovered that the plants date back to the Little Ice Age. Dr La Farge’s team took the samples, planted them in dishes full of nutrient-rich potting soil and fed them with water.
The samples were from four separate species including Aulacomnium turgidum, Distichium capillaceum, Encalypta procera and Syntrichia ruralis. The moss plants found by Dr La Farge are types of bryophytes. Bryophytes can survive long winters and regrow when the weather gets warmer.
However, Dr La Farge was surprised that the plants buried under ice have survived into the twenty-first century. Her findings appear in proceedings（论文集）of the National Academy of Sciences.
小题1:Dr La Farge’s research is of great importance to ________.
| A．knowing what the plants during the Little Ice Age were like |
| B．understanding how ecosystems recover from glaciers. |
| C．regrowing many species that have been destroyed before. |

| C．put my doubt out of my mind | D．was exactly what I had in my mind |
| A．lives better in small groups |
| B．is very active in hot weather |
| C．is strong enough to survive coldness |
| D．is chosen from Canadian refugia |
| A．Bryophyte ecology is greatly affected by climate change. |

| D．400-year-old plants were brought back to life. |
These experiments were conducted by psychological scientists, Nadia Chernyak and Tamar Kushnir of Cornell University. They found that sharing things with others when they are given a difficult choice leads children to think of themselves as people who like to share. It also makes them more likely to act in a pro-social （亲社会的）manner in the future.
Previous research has explained why rewarding children for sharing can backfire. Children come to think of themselves as people who don"t like to share since they had to be rewarded for doing so. Because they don"t view themselves as "sharers", they are less likely to share in the future.
Chernyak and Kushnir were interested in finding out whether freely chosen sacrifice might have the opposite effect on kids" willingness to share. To test this, the researchers introduced five-year-old children to Doggie, a sad puppet. Some of the children were given a difficult choice: Share a precious sticker（贴纸） with Doggie, or keep it for themselves. Other children were given an easy choice between sharing and putting the sticker away, while children in a third group were required by the researcher to share.
Later on, all the children were introduced to Ellie, another sad puppet. They were given the option of how many stickers to share (up to three). The kids who earlier made the difficult choice to help Doggie shared more stickers with Ellie. The children who were initially faced with an easy choice or who were required to give their sticker to Doggie, on the other hand, shared fewer stickers with Ellie. Therefore, children did not benefit from simply giving something up, but rather from willingly choosing to give something up of value.
“You might imagine that making difficult, costly choices is demanding for young children or even that once children share, they don’t feel the need to do so again,” Chernyak says. “But this wasn"t the case: once children made a difficult decision to give up something for someone else, they were more generous, not less, later on.” Chernyak concludes.
小题1:_______ helps children to share more in the future.
| A．Rewarding children for sharing |
| B．Forcing children to share |
| C．Allowing children to share precious things willingly |
| D．Allowing children to share what they don’t need |
| A．have an opposite effect | B．serve as a push |
| C．cause anger | D．avoid taking things back |
| A．they regret what they did | B．it’s not their own choice |
| C．Ellie is not as sad as Doggie | D．they like to share with a real person |
| A．parents will never find a way to get children to share toys |
| B．a gift should be given to make up for children’s sacrifice |
| C．children pretend to be generous when they are being observed |
| D．making difficult choices may influence sharing behavior |
Now colleges are seeing a change in the student lifestyle from outdoor enthusiasts to indoor couch potatoes and Internet addicts. The Internet and various on-campus services, from food delivery to laundry, are leading to a student culture of staying in dormitories. A student can have every need met without leaving the dormitory.
In the past two years Zhang Yi, 20, a junior majoring in law at Yangzhou University, has never been outside for sports except during physical education class. “I don’t think there is anything wrong with sleeping late in the morning and wanting to stay in the dormitory in my spare time. I have more fun doing things on my computer than playing on the sports ground in wet clothes.” said Zhang.
“With social networking sites, online games and micro-blogging added to already tight schedules, sports are often the last thing to be considered.” said Cheng Jie, 21, a senior majoring in civil engineering at the Southeast University in Nanjing.
But Jin Yinghua, a professor at Beijing Sports University, said that sports are not only for keeping fit, but also an irreplaceable(不能替代的) “education” for students. Sports are not only a way for students to train their body, but also an important way to learn responsibility, teamwork and devotion.
小题1:The first paragraph mainly tells us ________.
| A．the fingerprint punch-in clocks are widely used |
| B．some college students have poor memories |
| C．students cannot skip morning running any more |
| D．the problem of students skipping sports is serious |
| A．love sports more than anything else |
| B．prefer Internet games to sports |
| C．enjoy sleeping late in the morning |
| D．are too busy with study to do any sports |
| A．sports play an important role in students’ over-round development |
| B．the most important goal for students to do sports is to keep healthy |
| C．universities should take tough measures in student management |
| D．the spirit of responsibility can be developed in more than one way |
| A．Morning running at colleges | B．A new college life |
| C．Sports losing attraction | D．P.E. class at colleges |
Sian Beilock: “They start worrying about the consequences. They might even start worrying about whether this exam is going to prevent them from getting into the college they want. And when we worry，it actually uses up attention and memory resources. I talk about it as your cognitive horsepower that you could otherwise be using to focus on the exam.”
Professor Beilock and another researcher，Gerardo Ramirez，have developed a possible solution. Just before an exam，highly anxious test-takers spend ten minutes writing about their worries about the test.
Sian Beilock: “What we think happens is when students put it down on paper，they think about the worst that could happen and they reappraise the situation. They might realize it’s not as bad as they might think it was before and，in essence(本质上)，it prevents these thoughts from popping up when they’re actually taking a test.”
The researchers tested the idea on a group of twenty anxious college students. They gave them two short math tests. After the first one, they asked the students to either sit quietly or write about their feelings about the upcoming second test.
The researchers added to the pressure. They told the students that those who did well on the second test would get money. They also told them that their performance would affect other students as part of a team effort.
Professor Beilock says those who sat quietly scored an average of twelve percent worse on the second test. But the students who had written about their fears improved their performance by an average of five percent.
Next, the researchers used younger students in a biology class. They told them before final exams either to write about their feelings or to think about things unrelated to the test.
Prefessor Beilock says highly anxious students who did the writing got an average grade of B+，compared to a B－ for those who did not.
Sian Beilock: “What we showed is that for students who are highly test-anxious，who’d done our writing intervention(排解)，all of a sudden there was no relationship between test anxiety and performance. Those students most likely to worry were performing just as well as their classmates who don’t normally get nervous in these testing situations.”
But what if students do not have a chance to write about their fears immediately before an exam or presentation? Professor Beilock says students can try it themselves at home or in the library and still improve their performance.
小题1:Which of the following is TRUE?
| A．The result in the math test agrees with that in the biology test. |
| B．In the first math test, students who sat quietly performed better. |
| C．In the second math test, students who wrote about their feelings did worse. |
| D．Some college students are highly anxious test-takers while others are not in the tests. |
| A．Test anxiety is sure to cause students to fail the test. |
| B．Test anxiety can improve students’ performance to some degree. |
| C．Students’ attention and memory resources run out when worried. |
| D．Students may not be admitted into their favorite college if worried |
| A．proper amount of burden may turn out to be a good thing |
| B．facing the fears bravely may help one to achieve more |
| C．avoiding facing the problem may contribute to relaxation |
| D．taking no action before difficulty may result in success |
| A．It is important for students to overcome test anxiety. |
| B．Anxious students overcome test anxiety by writing down fears. |
| C．It is a common practice for students being worried before a test. |
| D．Being worried before tests does harm to students’ performance. |
Your brain isn’t a muscle, but you can treat it like one
Many people focus on physical fitness, but few know that brain fitness is also something you can work on. In fact, you can exercise your brain as often as you do to your arms or legs —and the results can be positive and empowering.
To improve your brain, you can’t simply repeat the same exercises over and over. Just as lifting a two—pound weight will stop challenging you, so will repetitive exercises such as crosswords or Sudoku. Once you master easy exercises, you must move on to harder ones in order to push your brain —like your muscles —to a new level.
The science behind brain training
Scientists once believed that your mental abilities were fixed in adulthood. Since studies have shown just the opposite, millions of people around the world have adopted the new practice of brain training. The most popular of these brain training products is made by the San Francisco—based Lumosity. Lumosity"s scientists with an experienced team of game designers have developed a fun，effective online brain training program that measures，tracks，and adapts to your progress，so you"ll always be challenged.
Promising studies on the effects of brain training
In a 2013 Stanford study，a treatment group of 21 breast cancer survivors used 12 weeks of Lumosity training to work on processing speed，mental flexibility，and working memory tasks. On average，those who trained improved on tests of these abilities，compared to a group that did not train with Lumosity.
There is even some evidence suggesting that Lumosity may be beneficial to normal，healthy adults. In a 2011 study by Lumosity and San Francisco State University researchers. 13 people who trained over 5 weeks improved working memory scores by 10％and attention scores by 20％.
Brain training is designed to meet real-life needs
The design of brain training is targeted at real-life benefits instead of improving game scores. Better attention，for example，can mean greater focus in the classroom or at an important business meeting. With improved processing speed，you might react and adapt faster to the demands of a busy life. And a better memory could mean stronger，longer relationships with the people closest to you.
小题1:We can learn from the passage that _________.
| A．brain training speeds up the recovery of breast cancer |
| B．your brain is like a muscle because it gives you power |
| C．people"s mental abilities can"t develop after they grow up |
| D．Lumosity can measure，track and suit your level as you improve |
| A．Better attention. | B．A better memory. |
| C．Better writing skills. | D．Higher processing speed. |
| A．People should care more about physical health instead of mental health. |
| B．Brain training has been proved effective through scientific researches. |
| C．A bad memory is the only reason for weak relationships with people. |
| D．Playing online games is the best way of brain training. |
| A．Brain Training Makes a Difference | B．Train Your Brain like a Muscle |
| C．Lumosity，Your Best Choice | D．How to Train Your Brain |
