 There are an extremely large number of ants worldwide. Each individual (个体的) ant hardly weigh anything, but put together they weigh roughly the same as all of mankind. They also live nearly everywhere, except on frozen mountain tops and around the poles.Foranimals their size, ants have been astonishingly successful, largely due to their wonderfulsocial behavior.

         In colonies (群体) that range in size from a few hundred to tens of millions, they organize their lives with a clear division of labor. Even more amazing is how they achievethis level of organization. Where we use sound and sight to communicate, ants dependprimarily on pheromone (外激素), chemicals sent out by individuals and smelled or tastedby fellow members of their colony. When an ant finds food, it produces a pheromone that will lead others straight to where the food is. When an individual ant comes under attack or is dying, it sends out an alarm pheromone to warn the colony to prepare for a conflict as a defense unit.

         In fact, when it comes to the art of war, ants have no equal. They are completely fearless and will readily take on a creature much larger than themselves, attacking in large groups and overcoming their target. Such is their devotion to the common good of the colony that not only soldier ants but also worker ants will sacrifice their lives to help defeat an enemy.

         Behaving in this selfless and devoted manner, these little creatures have survived on Earth, for more than 140 million years, far longer than dinosaurs. Because they think as one, they have a collective (集体的) intelligence greater than you would expect from itsindividual parts.

(1)、We can learn from the passage that ants are ____________.

A、not willing to share food B、not found around the poles C、more successful than all other animals        D、too many to achieve any level of organization
(2)、Ants can use pheromones for______.

A、escape          B、communication    C、warning enemies D、arranging labo
(3)、What does the underlined expression "take on" in Paragraph 3 mean?

A、Accept.    B、Employ.     C、Play with. D、Fight against.
(4)、Which of the following contributes most to the survival of ants?

A、Their behavior.   B、Their size.          C、Their number. D、Their weight

    Driving could soon be a far more pleasant experience thanks to a personal in-car robot being developed by researchers. The robot, which is called “Affective Intelligent Driving Agent (AIDA)” will be able to tell you the best route home based on traffic reports, remind you to pick up petrol and suggest places you may like to visit. The robot, which sits on the dashboard, is being developed at the Massachusetts Institute of Technology (MIT) in collaboration with Volkswagen.

    AIDA communicates with the driver through an expressive robot screen and will even appear sympathetic if you're having a bad day. Cynthia Breazeal, director of MIT's Personal Robots Group, said: “We are developing AIDA to read the driver's mood from facial expression and other cues and respond in a proper way.”

    AIDA works by analyzing the driver's mobility patterns, keeping track of common routes and destinations. The creators say the robot should be able to work out home and work locations within a week of driving. Soon afterwards, the system will direct the driver to their preferred supermarket, suggesting a route that avoids traffic-clogged roads. AIDA might recommend a petrol stop en route if the fuel tank is nearly empty. The robot will also incorporate real-time information about traffic jams, the weather report, commercial activity, tourist attractions, and residential areas.

    “In developing AIDA we asked ourselves how we could design a system that would offer the same kind of guidance as an informed and friendly companion.”

    “AIDA can also give you feedback on your driving, helping you achieve more energy efficiency and safer behavior,” Assaf Biderman from SENSEable City Lab added.

    Which boy hasn't dreamed of being a cool secret agent (特工)? The wonderful fighting abilities and the world-saving adventures are much more colorful than most people's everyday lives. Well, Cody Banks is just like any other boy, except that he is not just dreaming. He has a big secret his friends never know about. He was trained to be a spy (间谍)by a special CIA programme, which was made to look like a summer camp. He learned high-speed driving, hand-to-hand fighting and the use of high-tech tools.

    After proving he could become a young hero by saving a baby from a runaway car, Banks gets his first real task. He must make friends with a popular girl at school, Natalie Connors. Then, he must spy on her father, a scientist who has developed a dangerous technology (技术).Banks must stop a group of bad people from forcing Natalie's father into using the technology to endanger the world.

    The CIA may have taught him first-class self-defense moves, but they didn't show him how to talk to girls. Banks has zero ability when it comes to dealing with girls. How can he get around his problem and get an invitation to the girl's upcoming birthday party? Will he finally become Natalie's boyfriend and find out whatever he can about her father's work?

    Agent Cody Banks has everything that young people are interested in: big explosions, breath-taking performances and funny girl-dating experiences. It was listed No.2 in the American box office last week.

    “This story is interesting and fun for the whole family to enjoy, and especially cool for young boys,” said Paul Perkins, a film reviewer in the US.

    A new study by the British government has discovered the mental well-being of the country's teenage girls has worsened.

    The survey, which included 30,000 14-year-old students, showed 37 percent of the girls with psychological stress, rising from 34 percent in 2010. British boys' stress level was actually seen to fall over the same period, from 17 percent to 15 percent. The report's authors pointed out the "arrival of the social media age" could be a major contributing factor for increasing stress among teenage British girls.

    "The adolescent years are a time of rapid physical, cognitive and emotional development," Pam Ramsden, a lecturer in psychology at the University of Bradford in the United Kingdom, wrote in a recent blog post. "Teenagers interact with people in order to learn how to become competent adults. In the past, they would engage with parents, teachers and other adults in their community as well as extended family members and friends. Now we can also add social media to that list of social and emotional development." Throughout adolescence, girls and boys develop characteristics like confidence and self-control. Since teenage brains have not completely developed, teens don't have the cognitive awareness to keep from posting inappropriate content. Furthermore, this content can easily be circulated far and wide with disastrous implications.

    "Social media can also feed into girls' insecurities about their appearance," Ramsden said. These sites are often filled with images of people with body type unattainable to the normal person. However, these images and the messages tied to them creep into social standards.

    "Social media allows girls to make comparisons among friends as well as celebrities and then provides them with 'solutions' such as extreme dieting tips and workouts to reach their goals," Ramsden said. "Concerns about body image can negatively impact their quality of life preventing them from having healthy relationships and taking up time that could be better spent developing other aspects of their personalities."

Living a healthy lifestyle lies in forming the right eating habits. Here are some of the good habits you can develop when it comes to healthy eating.

Drink plenty of water, you must drink at least 8 glasses of water a day. You may need even more water if you are in a hot environment or if you are exercising.

Eat breakfast. Breakfast is the most important meal of the day. A recent study has shown that those who eat breakfast will use an average of 100 calories less during the day than their colleagues who skip breakfast. They will also be able to concentrate better.

Don't skip lunch. If you do so, your blood sugar level will drop and your metabolism (新陈代谢) will slow down. When you get home you are starving and eat everything you can find.

We all need to snack from time to time, but please choose your snacks carefully. In fact, it's a good idea to eat two healthy snacks besides your three main meals. Choose healthy snacks like fruits, low fat yogurt, cottage cheese with apple sauce.

Eat your fruits and vegetables. We should eat at least 5 servings of fruits and vegetables a day. Take a piece of fruit for a snack, add some bananas and raisins to your favourite breakfast cereal (谷类食物), have a salad of lunch, and eat at least one vegetable at dinner each night.

Do not eat your dinner too late. Try to eat dinner at least 3 hours before you go to bed, this will give your body a chance to digest most of the food before you rest for the next 8 hours. Plan dinner for the week ahead of time and make sure you have everything you need in the house so other family members can get ahead start on dinner if you have a late meeting at the office.

Are you a moviegoer? If, like me, you're a fan of film, then there's no better place to watch something than on the big screen at the cinema. You enter the dark theatre and take your seat, ready to be entertained. But while you are absorbed in some movie magic, many others are now getting their film fixed at home.

Over the last few years, cinemas have seen a comeback. Customers have been attracted by comfortable seats, and lots of choice of things to watch. Multiplexes in particular can screen up to twenty films at the same time, suiting all different tastes. In addition, 3D and even 4D movies can give the audience an extra immersive experience. So what's not to like about a trip to the cinema?

The coronavirus pandemic has put the future of cinema under the spotlight. Some have had to close because of reduced ticket sales. In the UK, it's brought about a surge in TV watching and online streaming. It's reported that half of UK adults will keep and continue using their new streaming subscriptions.

This isn't great news for cinemas. They rely on the release of a big blockbuster to bring the crowds back, but the launch of new films, such as James Bond: No Time To Die, are being delayed. Disney has released its $200m blockbuster, Mulan, online instead of in movie theatres. John Fithian, from the National Association of Theatre Owners, told Variety magazine: This idea of waiting out the pandemic to make your movies more profitable doesn't make sense to me. There won't be as much of an industry left to play your movies in if you do that. "
