◆ Timing
The absolutely best time in your life to study abroad is when you are in college. If you miss this opportunity, it’s almost impossible for you to do it later in life.
◆ To gain cross-cultural experience
Life overseas makes you see your everyday world in a whole new light. You don’t even realize it, but our culture shapes the way we view the world and affects us every minute of the day. Differences in culture are more than just differences in language, food, clothing and art.
◆ To improve your communication skills and your self-confidence
People who study abroad tend to be willing to take risks, willing to put themselves in unusual situations, and able to solve problems.
◆ To become more fluent in a language or to learn a new language
The world market is becoming smaller, and many companies require a second language. Foreign languages are not only valuable in the job market but also valuable in the real world.
◆ For the adventure
Travel to other cities within your host country and around neighboring countries. As you get to know your new classmates, roommates, and host family, you will gain a unique view on the host culture. Discover the differences and, more importantly, the many similarities between your worlds. The friendships you make will last long after the program.
◆ To learn more about yourself
Find out who you really are. What are your limits? How do you overcome the difficulties you’ve never encountered before? How independent are you? These questions are hard to answer until you are removed from your usual surroundings. After solving difficult problems on your own overseas, you’ll find that almost nothing will confuse you at home. Students who study abroad commonly report that their study abroad experience actually changed their lives.

举一反三
Stage 1: Prepare the equipment: a test tube, a crucible, a Bunsen burner and tongs.
Stage 2: Weigh 5 grams of baking soda (sodium bicarbonate) and put it in a crucible.
Stage 3: Heat 10 ml of hydrochloric acid (盐酸) in a test tube.
Stage 4: Pour the warm acid onto the baking soda and continue to heat the mixture.
Result: The acid reacts with the bicarbonate（碳酸氢盐）to form water, carbon dioxide gas and salt. The hotter the mixture, the quicker the reaction. Continue to heat the mixture until the water evaporates, leaving the salt in the crucible.
Paul and his partner followed the instructions and set up their equipment. Paul went to the cupboard to get a bottle of hydrochloric acid. He found that there was only one bottle in the cupboard so he took that. There was no label on the bottle and Paul didn’t check with the teacher if it was the right solution.
He measured the liquid and poured it into a test tube. Using tongs to hold the test tube, he heated it over the Bunsen burner. That’s when things started to go wrong. The liquid in the test tube was not hydrochloric acid. When it was heated, it formed a thick cloud of white gas. Soon the room was full of this strong smelling white gas.
All the students started coughing and their eyes hurt. The teacher immediately opened the windows and ordered the students to leave the laboratory at once. She realized that the liquid was a crylamide (丙烯酰胺) and that it is poisonous.
Fortunately, nobody was injured in the incident. However, it taught the students and the teacher a good lesson.
小题1:What lesson did the incident teach the students and the teacher?
| A．Never have a bottle without a label in the chemistry lab! |
| B．Obey your teacher’s instructions in the Chemistry lab. |
| C．A crylamide can’t take the place of hydrochloric acid. |
| D．Finding something unusual happened, you have to leave the laboratory at once. |
| A．Water | B．Carbon dioxide gas | C．Salt | D．Poisonous gas |
| A．He went to the cupboard to get the bottle by himself. |
| B．He found that there was only one bottle in the cupboard so he took that. |
| C．There was no label on the bottle. |
| D．Paul didn’t check with the teacher that it was the right solution. |
| A．Becausethe room was full of this strong smelling white gas. |
| B．Because all the students started coughing and their eyes hurt. |
| C．Becausethe liquid was a crylamide and that it is poisonous. |
| D．Because someone was injured in the incident. |
techniques , but he admitted there would be difficulties in meeting his goal .
“ For example , if you run out of ink while printing on paper , you will throw that paper away . But you cannot throw half-completed buildings away if your material gets stuck , ” he said . Although the printed house is not available to visit , there is a chance for people in Shanghai to see items printed in 3D.
The Belgium-based company Materialise NV held a 3D printing exhibition in Shanghai that started in late 2012 and ended in the middle of 2013 . The company is eager to show Asia what is possible with 3D printing .
“ All the pieces shown here are what cannot be made through traditional techniques . A good example of this customization is hearing aids . More than 10 million people already use 3D printed hearing aids, all made according to the size of their ears , ” said Wim Michiels , executive vice-president at Materialise NV .
“ You can produce anything whenever and wherever you like . You don’t need to set up production lines for pieces that only need a limited amount of products . Setting up a production line is a lot of work . It takes a long time and is very expensive for a limited number of pieces , ” said Michiels .
Kim Francois , managing director of Materialise China , said their European and American clients have already taken the next step toward additive manufacturing with small series production such as hearing aids .

Teaching and learning are two entirely different processes. They differ in kind and function. The function of teaching is to create the conditions and the climate that will make it possible for children to devise the most efficient system for teaching themselves to read. Teaching is also public activity. It can be seen and observed.
Learning to read involves all that each individual does to make sense of the world of printed language. Almost all of it is private, for learning is an occupation of the mind, and that process is not open to public scrutiny.
If teacher and learner roles are not interchangeable, what then can be done through teaching that will aid the child in the quest（探索）for knowledge? Smith has one principal rule for all teaching instructions. “Make learning to read easy, which means making reading a meaningful, enjoyable and frequent experience for children.”
When the roles of teacher and learner are seen for what they are, and when both teacher fulfill them appropriately, then much of the pressure and feeling of failure for both is eliminated. Learning to read is made easier when teachers create an environment where children are given the opportunity to solve the problem of leaning to read by reading.
小题1:The problem with the reading course as mentioned in the first paragraph is that ________.
| A．it is one of the most difficult school courses |
| B．students spend endless hours in reading |
| C．reading tasks are assigned with little guidance |
| D．too much time is spent in teaching about reading |
| A．teachers can improve conditions at school for the students |
| B．teachers can enable students to develop their own way of reading |
| C．teachers can devise the most efficient system for reading |
| D．teachers can make their teaching activities observable |
| A．inquiry | B．observation | C．control | D．suspicion |
| A．children become highly motivated |
| B．teacher and learner roles are interchangeable |
| C．teaching helps children in the search for knowledge |
| D．reading enriches children’s experience |
| A．teachers should do as little as possible in helping students learn to read |
| B．teachers should encourage students to read as widely as possible |
| C．reading ability is something acquired rather than taught |
| D．reading is more complicated that generally believed |
Beneath the surface of a gemstone, on the tiny level of atoms and molecules（分子）, lie clues (线索) to its origin. At this year’s meeting of the Geological Society of America in Minneapolis, Catherine McManus reported on a technique that uses lasers (激光) to clarify these clues and identify a stone’s homeland. McManus directs scientific research at Materialytics, in Killeen, Texas. The company is developing the technique. “With enough data, we could identify which country, which mining place, even the individual mine a gemstone comes from,” McManus told Science News.
Some gemstones, including many diamonds, come from war-torn countries. Sales of those “blood minerals” may encourage violent civil wars where innocent people are injured or killed. In an effort to reduce the trade in blood minerals, the U.S. government passed law in July 2010 that requires companies that sell gemstones to determine the origins of their stones.
To figure out where gemstones come from, McManus and her team focus a powerful laser on a small sample of the gemstone. The technique is called laser-induced breakdown spectroscopy. Just as heat can turn ice into water or water into steam, energy from the laser changes the state of matter of the stone. The laser changes a miniscule part of the gemstone into plasma, a gas state of matter in which tiny particles（微粒）called electrons separate from atoms.
The plasma, which is superhot, produces a light pattern. (The science of analyzing this kind of light pattern is called spectroscopy.) Different elements（元素）produce different patterns, but McManus and her team say that gemstones from the same area produce similar patterns. Materialytics has already collected patterns from thousands of gemstones, including more than 200 from diamonds. They can compare the light pattern from an unknown gemstone to patterns they do know and look for a match. The light pattern acts like a signature, telling the researchers the origin of the gemstone.
In a small test, the laser technique correctly identified the origins of 95 out of every 100 diamonds. For gemstones like emeralds and rubies, the technique proved successful for 98 out of every 100 stones. The scientists need to collect and analyze more samples, including those from war-torn countries, before the tool is ready for commercial use.
Scientists like Barbara Dutrow, a mineralogist from Louisiana State University in Baton Rouge, find the technique exciting. “This is a basic new tool that could provide a better fingerprint of a material from a particular locality,” she told Science News.

But just what does it mean to say someone is “cool”? Most would answer that it is something to do with being independent-minded and not following the crowd.
Yale University art professor Robert Farris Thompson says that the term “cool” goes back to 15th century West African philosophy(哲学). “Cool” relates to ideas of grace(优雅) under pressure.
“In Africa, ” he writes, “coolness is a positive quality which combines calmness, silence, and life.”
The modern idea of “cool” developed largely in the US in the period after World War II. “Post-war ‘cool’ was in part an expression of war-weariness (n. 厌战情绪)
. . . it went against the strict social rules of the time,” write sociologists Dick Pountain and David Robins in Cool Rules:Anatomy of an Attitude.
But it was the American actor James Dean who became the symbol for “cool” in the hugely successful 1955 movie Rebel without a Cause. Dean plays a tough guy who disobeys his parents and the authorities. He always gets the girl, smokes cigarettes, wears a leather jacket and beats up bullies(欺凌弱小者). In the movie, Dean showed what “cool” would mean to American young people for the next 60 years.
Today the focus of “cool” has changed to athletics (体育运动) stars. Often in movies about schools, students gain popularity on the athletics field more than in the classroom. This can be seen quite clearly in movies like Varsity Blues and John Tucker Must Die.
But many teenagers also think being smart is cool. Chess and other thinking games have been becoming more popular in schools.
“Call it the Harry Potterization of America—a time when being smart is the new cool,” writes journalist Joe Sunnen.

| D．had all kinds of “bad” manners |
| A．do very well in their studies |
| B．are very skilled at sports |
| C．are good at chess and other thinking games. |
| D．have supernatural powers like Harry Potter |
| A．It is generally considered “cool” to be independent-minded and not to follow the crowd. |
| B．“Cool” was used as early as the 15th century. |
| C．Disobeying one’s parents and the authorities is considered “cool” among American young people nowadays. |
| D．Getting the first place in an exam can also be considered “cool”. |
| A．The origin of the word “cool”. |
| B．The kinds of people who are “cool”. |
