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(低一等的) 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 understand 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 _________．
| A．leaves the group itself | B．has breeding rights |
| C．eats its competitor | D．faces danger |
The underlined words "the evicted fish" in Paragraph 3 refer to _________．

| C．the fish found out | D．the fish fattened up |
The experiment showed that the smaller fish _________．
| A．fought over a feast | B．preferred some extra food |
| C．challenged the boss fish | D．went on diet willingly |
What is the text mainly about?
| A．Fish dieting and human dieting． | B．Dieting and health． |
| C．Human dieting． | D．Fish dieting． |
Last week, I bought an alarm system for about $ 450. It consisted of a control unit with three small units. I put the control unit in the sitting-room and fastened the other units by the front door, back door and living-room windows. The instructions told us to choose three numbers, so we chose 4, 9 and 1, the last three numbers of our telephone number.
Now I must explain how the alarm works:
l There is a power siren(警报器) in the control unit. It makes a very loud noise.
2 Each of the small units sends out beams or rays in different directions. If anything moves, it breaks a beam. This sends a signal to the control unit. The siren makes a noise which you can hear 50 meters away.
3. When we go to bed, I press the three buttons numbered 4, 9 and 1. Then we have 30 seconds to get out of the room before the alarm starts to work.
That night I slept soundly because I was sure that no burglar(夜贼) could get into our house. However, at about 2:10 a. m., I woke up and heard the siren. “There must be a burglar in the house,” Mary said. “What shall we do?”“I’ll go and see who’s there,” I said. “Stay here. Don’t make a noise.”I went downstairs quietly. When I reached the living-room, I switched on my torch and looked round the room. Then I turned the light on. I switched the siren off and searched the rooms downstairs. There was nothing wrong except that the back door was unlocked. I locked it, reset the alarm and went back to bed. About an hour later, the alarm started again. I jumped out of bed, fell over a chair in the dark and bumped into the bedroom door. Mary woke up and started hitting me with a torch. “Hey! Wait a minute!” I whispered. “It’s only me. I’m going downstairs to see what’s wrong.”I went down into the living-room and listened for a moment. The only sound I could hear was the siren. I turned on the light and then switched the siren off. As I did so, I glanced across at the curtains in front of the windows. I saw a house lizard (a kind of small animal) disappear behind the curtains.“Oh!” I said to myself. “That’s our burglar. ”When the lizard moved, it started the siren. I guessed that the alarm had been made in Europe, where there are no house lizards. Well. I won’t finish this story but if you want an alarm system free of charge, let me know. I’ll send you ours. We bought a dog this morning. It knows the difference between a lizard and a burglar.The writer bought an alarm system to ________.
| A．make sure that he got up early every day |
| B．warn him when there were lizards in his house |
| C．frighten burglars and tell him that somebody had got into the house |
| D．make Mary feel safe to live in the large room |
The purpose of the three units was to________.
| A．send a message to the control unit and start the siren |
| B．sound their own sirens when the control unit told them so |
| C．check that the control unit worked properly all the time |
| D．give them enough light |
If the writer set the alarm and remained in the room for more than half a minute, _______.
| A．nothing would happen |
| B．the control unit would not work |
| C．the siren would make a noise |
| D．the dog would bark |
The purpose of the writer in writing the passage is to ________.
| A．tell us that the alarm system doesn’t work |
| B．tell us an interesting experience |
| C．show us how the alarm system works |
| D．make it clear that he wants to give away his alarm system |

 1. Cousins You could say that the alligator and the crocodile are cousins because they belong to the same animal group. The group is called Archosauria (ark-o-SOR-ee-ah). The name means "ruling lizards." The alligator and the crocodile are alike in many ways. Both have hard, bumpy skin. Both lay eggs in nests that they build near water. Both are reptiles (爬行动物), too.  2. Look Again Even though alligators and crocodiles are similar, there are ways to tell them apart. Adult alligators are usually gray or black, and they are darker than crocodiles. Adult crocodiles may be tan, green, or brown. Most types of alligators have broad snouts. Crocodiles' snouts are different. Their snouts are long and narrow. Look at the picture of the alligator. Whenever an alligator closes its mouth, only the top teeth show. Now look at the picture of the crocodile. Do you see a difference? Whenever a crocodile closes its mouth, some of the lower teeth also show.  3 Alligators and crocodile also have different ways of doing things. Alligators like freshwater. They sometimes wander into salty seawater, but they don't stay in the water very long. The salt can be bad for them. Alligators usually make their nests at the edge of freshwater lakes, rivers, or swamps. They use grass and leaves to make their nests. Crocodiles, on the other hand, usually build their nests in mud or sand. Sometimes they construct these nests near salty water. The salty water doesn't hurt them. Alligators and crocodiles do other things differently, too. A mother alligator stays near her nest. When the eggs hatch, she carries the babies to water. They may even ride around on her head as she swims. They depend on her to help them stay safe. Crocodile babies don't rely as much on their mothers. In fact, the babies leave the nest a few days after they are born. |
Where do they (alligators and crocodiles) lay eggs?
According to Part 2 "Look Again", how can we tell alligators and crocodiles apart?
What might be a suitable heading for Part 3?
According to the passage, who rely more on their mothers?
Who is the passage most likely intended for?
Testing has replaced teaching in most public schools. My own children's school week is framed by pretests, drills, tests, and retests. They know that the best way to read a textbook is to look at the questions at the end of the chapter and then skim the text for the answers. I believe that my daughter Erica, who gets excellent marks, has never read a chapter of any of her school textbooks all the way through. And teachers are often heard to state proudly and openly that they teach to the mandated (国家指定的) state test.
Teaching to the test is a curious phenomenon. Instead of deciding what skills students ought to learn, helping students learn them, and then using some reasonable methods of assessment to discover whether students have mastered the skills, teachers are encouraged to reverse the process. First, one looks at a commercially available test. Then, one distills (提取) the skills needed not to master reading, say, or math, but to do well on the test. Finally, the test skills are taught.
The ability to read or write or calculate might infer the ability to do reasonably well on standardized tests. However, neither reading nor writing develops simply through being taught to take tests. We must be careful to avoid mistaking preparation for a test of a skill with the acquisition of that skill. Too many discussions of the basics of skills make this fundamental confusion because people are test-centered rather than concerned with the nature and quality of what is taught.
Recently, many schools have faced what could be called the crisis of comprehension or, in simple terms, the phenomenon of students with phonic and grammar skills still being unable to understand what they read. These students are capable of taking tests and filling in workbooks. However, they have little or no experience reading or thinking, and talking about what they read. They know the details but can't see or understand the whole. They are taught to be so concerned with grade that they have' no time or ease of mind to think about meaning, and reread things if necessary.As is indicated in the second paragraph, the author finds it strange that __.
| A．tests are used to assess students' skills |
| B．skills are determined before tests are set |
| C．teaching is aimed to prepare students for tests |
| D．teachers use some reasonable methods of assessment |
The crisis of comprehension most probably results from __.
| A．students' poor phonic and grammar skills |
| B．teaching that takes up much of students' free time |
| C．teaching that emphasizes details rather than the whole |
| D．students' lack of ability to think about what they read |
According to the author, we can infer that __.
| A．the basics of skills have been discussed too much |
| B．the nature and quality of what is taught are fully concerned |
| C．skills in general are not only useless but often mislead students |
| D．doing well in a test does not necessarily mean acquiring the skill |
The British are being encouraged to holiday at home as a major tourism drive offering Olympic themed discounts is launched next week.
A new campaign offering 20. 12% discounted bills at participating venues (场所) will be announced publicly for the first time by Culture Secretary Jeremy Hunt on Wednesday to encourage "staycations".
The scheme includes hotel accommodation, meals, guided tours and entry to attractions, with discounts funded by the industry. Government officials said more than three million hotel rooms were already lined up under the project, which is being backed by a range of companies, including Butlins. Attractions, such as the London Eye and Alton Towers, are also taking part. Reduced prices will also be offered on stays on the Royal yacht Britannia, now harboring in Leith, Edinburgh, and visits to Chatsworth, the historic house in Derbyshire.
Tourists will be able to take advantage of the discount by using a dedicated website before the end of the Paralympics on September 9 to make bookings for this year and 2013.
Mr. Hunt said, "With the Diamond Jubilee and the 2012 Olympic Games, this year is the perfect opportunity for more of us to holiday in the UK "
Mr. Hunt has travelled the UK, urging companies to take part in the scheme, telling them, "It's now or never for London tourism. We will never have a year like 2012 to show the world that this is, quite simply, the most exciting, vibrant, cosmopolitan city on the planet. The unavoidable complaints in the run up to an Olympics must not cloud the scale of the opportunity —including our biggest ever tourism marketing campaign to make sure we get a lasting benefit from being in the global spotlight. "
The scheme will be promoted by a ￡3 million television advertising campaign — the first of its kind in the UK.
The government hopes the " Holidays at Home are Great" campaign — launched by Visit England — will create 12, 000 jobs, create 5.3 million extra short overnight breaks, and generate ￡480 million in extra spending over three years.What Mr. Hunt said indicates that.
| A．he has no interest in the scheme |

The necktie looks set to follow the top hat in being handed over to the fashion museum by office workers within the next 50 years, according to research.
Nearly three quarters (74%) think the tie will not survive within British firms beyond the next half a century with the popularity of the open-collared shirt. Its demise is being blamed on the boom in creative businesses, such as Facebook and Google, and online trading companies where formal dress codes tend to be avoided in favour of a more casual approach.
Once considered an important part of business dress, the tie has become a victim of the spread of "casual Fridays" into other weekdays, according to researchers.
The poll, by Deal Jungle. com, which helps small and medium enterprises, found more than half (51% ) thought the tie would die out in offices within the next 20 years and almost a quarter (22%) believed it would last less than 10 years.
A spokesman for the site, which has 20, 000 registered members, said: "Ties have been around seemingly forever but increasing numbers of office workers are telling them to get away."
"The success of businesses such as Facebook and Google, where even the CEO turns up wearing jeans and a hoodie, also seems to have had a corrosive (侵蚀性) effect on the idea of dressing formally for work."
"Many of our members keep their expenses to a minimum by working from home so they feel no need to dress up to go to work. We know that when they meet with clients, they still put on a business suit, but a tie is no longer seen as an essential part of the suited-and-booted look."
"Instead, many businessmen and increasing numbers of executives choose a suit and shirt with an open collar. The tie-less suit creates an impression of a more approachable deal maker, someone who is still business-minded, yet creative and technology-sensible, too. "Why are ties expected to disappear in offices?
| A．CEOs in creative businesses set a rule to forbid wearing ties. |
| B．The idea of casual weekdays is increasingly accepted. |
| C．Office workers are tired of wearing ties daily. |
| D．The tie-less look appears more modern. |
According to the spokesman, how are their members dressed before clients?
| A．Business suits and casual jeans. |
| B．Formal suits and a shirt with a tie. |
| C．Casual suits and buttoned-up shirt. |
| D．Business suits and an open-collared shirt. |
What kind of image does the tie-less suit create?
| A．Accessible in business. | B．Professional in fashion. |
| C．Casual in working. | D．Creative in dressing. |
What does the underlined word "demise" mean in Para.2?
| A．popularity | B．survival | C．disappearance | D．development |
