People diet to look more attractive. Fish diet to avoid being beaten up, thrown out of their social group, and getting eaten as a result. That is the fascinating conclusion of the latest research into fish behavior by a team of Australian scientists.
The research team have discovered that subordinate fish voluntarily diet to avoid challenging their larger competitors. “In studying gobies we noticed that only the largest two individuals, a male and female, had breeding （繁殖） rights within the group,” explains Marian Wong. “All other group members are nonbreeding females, each being 5-10% smaller than its next largest competitor. We wanted to find out how they maintain this precise size separation.”
The reason for the size difference was easy to see. Once a subordinate fish grows to within 5-10% of the size of its larger competitor, it causes a fight which usually ends in the smaller goby being driven away from the group. More often than not, the evicted fish is then eaten up.
It appeared that the smaller fish were keeping themselves small in order to avoid challenging the boss fish. Whether they did so voluntarily, by restraining how much they ate, was not clear. The research team decided to do an experiment. They tried to fatten up some of the subordinate gobies to see what happened. To their surprise, the gobies simply refused the extra food they were offered, clearly preferring to remain small and avoid fights, over having a feast.
The discovery challenges the traditional scientific view of how boss individuals keep their position in a group. Previously it was thought that large individuals simply used their weight and size to threaten their subordinates and take more of the food for themselves, so keeping their competitors small.
While the habits of gobies may seem a little mysterious, Dr. Wong explains that understanding the relationships between boss and subordinate animals is important to understanding how hierarchical （等级的） societies remain stable.
The research has proved the fact that voluntary dieting is a habit far from exclusive to humans. “As yet, we lack a complete understanding of how widespread the voluntary reduction of food intake is in nature,” the researchers comment. “Data on human dieting suggests that, while humans generally diet to improve health or increase attractiveness, rarely does it improve long-term health and males regularly prefer females that are fatter than the females’ own ideal.”When a goby grows to within 5-10% of the size of its larger competitor, it .

New rules will let millions of Americans know where more of their food comes from. The law is known as COOL -- Country of Origin Labeling(标签).
American congress first passed the law in 2002. Stores have had to label seafood by country of origin since 2005. But industry pressure delayed other requirements until last week.
Products that must now be labeled include fresh fruits and vegetables, muscle meats and some kinds of nuts. But the rules are complex, and many foods are not included. For example, organ meats are free to be labeled. So are processed foods, including cooked or smoked foods.
The same food may sometimes have to be labeled and other times not. Fresh or frozen peas, for example, have to be labeled but not canned peas. Foods that are mixed with other foods are also excluded. Mixed nuts, for example, do not need to be labeled. The same is true of a salad mix that contains different things like lettuce and carrots. Or a fruit cup that combines different fruits. Also, the law doesn’t include restaurants and other food service organizations. Department of Agriculture officials say the law is really meant for larger grocery stores.
The United States has imported more and more food in recent years to save money and expand choices. Country-of-origin labeling has become more common lately but has still been limited in many stores.
Food safety is one reason why some shoppers pay close attention to where foods came from. For example, when a large number of people recently got sick from salmonella(沙门菌病), officials blamed peppers from Mexico. Yet the last big food scare involved spinach grown in California. But labeling is also a way for people to know they are getting what they want. Some want to buy local foods or foods from a particular country.
The country-of-origin labeling law gives stores 30 days to correct any violations(违反) that are found. Stores and suppliers that are found to be deliberately violating the law could be fined 1,000 dollars per violation. Federal inspectors are not to take action to enforce the law for six months to give time for an education campaign.
Some food safety activists say they are generally pleased with the law. They call it a good step that will give people more useful information. Why has more and more food been imported to the United States in recent years?
| A．It is economical and provides people with more choices. |
| B．Foreign food is of higher quality than native food. |
| C．Americans need more and more food recently. |
| D．The United States is short of food supply. |
Consumers are more concerned about where foods come from because________.
| A．they are curious about the origin of the food. |
| B．most of them are particular about the tastes |
| C．they are concerned about food safety |
| D．most of them are food safety activists |
The new rules of the country-of-origin labeling law will come into effect________.
| A．right now | B．in a month | C．in three months | D．in half a year |
Which of the following can be inferred from the text?
| A．Store owners are most likely to be the supporters of the law. |
| B．The government of America will possibly forbid importing peppers from Mexico. |
| C．Federal inspectors couldn’t take measures to enforce the law. |
| D．Most Americans prefer imported vegetables to the vegetables grown in local places. |
My favorite English teacher could draw humor out of the driest material. It wasn’t forced on us either. He took Samuel Johnson’s dictionary, Addison’s essays, and many other literary wonders from the eighteenth century and made them hilarious, even at eight o’clock in the morning. The thing that amazed me most was that the first time I read these works on my own, some of them seemed dead, but the second time, after his explanation, I couldn’t believe that I hadn’t seen the humor. The stories and poems and plays were suddenly filled with allusions(典故) and irony and hilarious moments. I learned more from him than from any other teacher.
My least favorite English teacher also made people laugh. Some students found him to be wonderfully funny. Many others did not. He assigned journals over a six-week period, to be written every day. At the end of the six weeks I had a notebook full of bits and pieces about my ideas, short stories, reactions to what we had read, and so on. Our teacher announced that we would be grading each other’s journals. Mine was passed to Joe, that class clown, who always behaved in a funny or silly way. He saw it fit to make a joke of and said, “This writing isn’t fit to line the bottom of a birdcage.” Our teacher laughed at that funny remark. It hurt me so much that the anger from it has driven my writing and teaching ever since.
So what makes the difference? Humor is one of the most powerful tools teachers or writers have. It can build up students and classes and make them excited about literature and writing, or it can tear them apart. It is true that humor is either productive or counter-productive and self-defeating. The passage mainly discusses ________.
| A．teaching | B．literature | C．humor | D．knowledge |
The underlined word “hilarious” in Paragraph 1 probably means ________.
| A．funny | B．tiring | C．inspiring | D．brilliant |
The English teacher the writer disliked most ________.
| A．was not able to make students laugh |
| B．hurt his student’s feelings |
| C．didn’t let his students do the grading |
| D．had no sense of humor |
Kids at the Interlake School Division were the first Canadian students to take part in a program to send experiments to the International Space Station.(ISS).
Jordan Schott and three other sixth grade students came up with the idea to test royal jelly(蜂王浆) in space . Their experiment came very close to be tested on the space station. “We were seeing if we could send it to space, and if it would lose its nutritional value” faster and or slower, ”said Schott. Schott is one of the 18 students in the Space Knights Club at Woodlands Elementary School, part of the Interlake School Division. Over 450 students from the Division took part in the program.
“I thought we were just students and we couldn’t do much in the way of that. It’s a way to communicate with people up there ,” said Braeden Clark, a seventh grade student who is also in the club.
The astronauts shared what they learned with their school with a full day of activities all about science and space.
Teacher Maria Nickel is the organizer of the club. She said the day was great for students to learn what they could do. “Space is one of those great things that get kids excited, but it also gives them the chance to do so much. They can be an astronaut; they can be an engineer, ”She said.
The day was held in honour of Chris Hadfield, a Canadian astronaut now in the Internal Space Station. “It gives kids someone more to look up to. Here’s a real hero to look up to who’s doing it all, doing it through education,” said Nickel.
Jordan Schott thinks it’s really cool. “To me it seems so cool how people can go up to space, and science is something I’ve always liked,” She said. Schott says she wants to follow in the footsteps of Hadfield and be an astronaut when she gets older.
