The value-packed, all-inclusive sight-seeing package that combines the best of Sydney's harbor, city, bay and beach highlights.

    A SydneyPass gives you unlimited and flexible travel on the Explorer Buses: the ‘red' Sydney Explorer shows you around our exciting city sights while the ‘blue' Bondi Explorer visits Sydney Harbour bays and famous beaches. Take to the water on one of three magnificent daily harbor cruises (游船). You can also travel free on regular Sydney Buses, Sydney Ferries or CityRail services (limited area), so you can go to every corner of this beautiful city.

    Imagine browsing at Darling Harbour, tasting the famous seafood at Watsons Bay or enjoying the city lights on an evening ferry cruise. The possibilities and plans are endless with a SydneyPass. Wherever you decide to go, remember that bookings are not required on any of our services so tickets are treated on a first in, first seated basis.

    SydneyPasses are available for 3, 5 or 7 days for use over a 7-calendar-day period. With a 3 or 5-day pass you choose on which days out of the 7 you want to use it. All SydneyPasses include a free Airport Express inward trip before starting your 3, 5 or 7 days, and the return trip is valid  for 2 months from the first day your ticket was used.

    It is good to get in touch with your inner child from time to time, and obviously some people are willing to pay big money for the chance to do so in a proper environment. A Brooklyn-based adult preschool is charging customers between $333 and $999 for the chance to act like a kid again.

    At Preschool Mastermind in New York adults get to participate in show—and—tell, arts—and—crafts such as finger paint, games like musical chairs and even take naps. The month-long course also has class picture day where the adults are expected to have a field trip and a parent day.

    30-year-old Michelle Joni Lapidos, the brain behind the adult preschool, studied childhood education and has always wanted to be a preschool teacher. She's always on the lookout for new ways to get people in touch with the freedom of childhood. A friend encouraged her to start the mastermind course instead.

    According to Candice, her blogger friend, Preschool Mastermind gives adults a chance to relearn and master the things that they failed to understand as children. "I realized all the significances of what we learn in preschool," said founder Michelle Joni, "People come here and get in touch with their inner child. It's magical. We are bringing ourselves back to another place, another time with ourselves when we are more believing in ourselves, more confident and ready to take on the world."

    "One person's here because they want to learn not to be so serious." Michelle said. "Another's here to learn to be more confident." She explained that most of the classes were planned. However, Joni added that while the planned activities were fun, it was often the spontaneous(自发的)moments that attracted students. "It's the things you don't plan for, the sharing between friends and learning from each other."

    For thousands of years, people have known that the best way to understand a concept is to explain it to someone else. "While we teach, we learn," said Roman philosopher Seneca. Now scientists are bringing this ancient wisdom up to date. They're documenting why teaching is such a fruitful w ay to learn, and designing creative ways for young people to take part in instruction.

    Researchers have found that students who sign up to tutor others work harder to understand the material, recall it more accurately and apply it more effectively. Student teachers score higher on tests than pupils who're learning only for their own sake. But how can children, still learning themselves, teach others? One answer: They can tutor younger kids. Some studies have found that first-born children are more intelligent than their later-born siblings(兄弟姐妹). This suggests their higher IQs result from the time they spend teaching their siblings. Now educators are experimenting with ways to apply this model to academic subjects. They arrange college undergraduates to teach computer science to high school students, who in turn instruct middle school students on the topic.

    But the most cutting-edge tool under development is the "teachable agent" — a computerized character who learns, tries, makes mistakes and asks questions just like a real-world pupil.

    Computer scientists have created an animated(动画的)figure called Betty's Brain, who has been "taught" about environmental science by hundreds of middle school students. Student teachers are inspired to help Betty master certain materials. While preparing to teach, they organize their know ledge and improve their own understanding. And as they explain the information to it, they identify problems in their own thinking.

    Feedback from the teachable agents further improves the tutors' learning. The agents' questions forces student tutors to think and explain the materials in different ways, and watching the agent solve problems allow s them to see their know ledge put into action.

    Above all, it's the emotions one experiences in teaching that improve learning. Student tutors feel upset when their teachable agents fail, but happy when these virtual pupils succeed as they develop pride and satisfaction from someone else's accomplishment.

    For many of us, summertime means road trips to the beach or mountains, or at the very least some additional dust and bird poop on the exterior of our vehicles. The extra dirt leads us to do one of two things: wash our car in the driveway or head to the car wash. But which choice is better for the environment?

    The main concerns with either choice are the amount of fresh water being used and the types of chemicals used to remove the dirt. Both of these concerns can be closely monitored when washing the car at home, says Katy Gresh, spokeswoman for the Southwest Region of the Pennsylvania Department of Environmental Protection. She advises car owners to put aside a set amount of water for the entire wash. "It's just like brushing your teeth," she says, "You don't want to leave the water running of more than you need for the job." But even following this advice comes with an environmental risk: Washing your car in the driveway or street flushes the dirty water into storm drains.

    John Schombert, executive director of 3 Rivers Wet Weather, his organization works to educate the public about storm sewers (下水道) and water runoff, keeping this untreated water from entering the Allegheny region's waterways. "We ask people to, consider washing their cars on lawns or other permeable (透水的) surfaces where the water gets absorbed," Schombert says. "Soil can break down and help filter (过滤) those things," Schombert says. "Storm sewers are not made for waste disposal." Even when car owners use natural soaps to wash their cars, which Schombert says are probably ineffective at breaking down grease anyway.

    The commercial car wash down the street knows full well the rules regarding wastewater in storm sewers. According to the International Carwash Association (ICA), professional car washes must use water reclamation systems. These mandated processes not only keep the dirty water out of storm sewers and regular water treatment systems, but they also work to reduce water usage at commercial facilities.

My, what a big beak you have!

For humans, adapting to climate change will mostly be a matter of technology. More air conditioning, better-designed houses and bigger flood defenses may help to make the effects of a warmer world less harmful. {#blank#}1{#/blank#}In a paper published in Trends & Evolution, a team led by Sara Ryding, a PhD candidate at Deakin University, shows that is already. happening. Climate change is already changing the bodies of many animal species: bigger beaks (喙), limbs and ears.

In some species of Australian parrot, for instance, beak size has increased by between 4% and 10%since 1871. Another study, this time in North American dark-eyed juncos, another bird, found the same pattern.{#blank#}2{#/blank#}.

All that is perfectly consistent with evolutionary (进化) theory, "Allen's rule". Allen suggested it in 1877, holding that warm-blooded animals in hot places tend to have larger body parts than those in temperate (温带的) regions.{#blank#}3{#/blank#}Being richly filled with blood vessels (血管), and not covered by feathers, beaks make an ideal place for birds to get rid of heat.

Ms. Ryding examined museum specimens (标本) to prove that climate change was the cause of an anatomical (解剖学的) changes. All sorts of other factors might have been driving the changes. Her team combined data from different species in different places. They have little in common apart from living on a warming planet.{#blank#}4{#/blank#}.

For now, at least, the increase is small, never much more than 10%{#blank#}5{#/blank#}Since any evolutionary adaptation comes with trade-offs (妥协), it is unclear how far the process might go.

A. Therefore, climate change is the most reasonable explanation.

B. That may change as warming accelerates (加速).

C. Animals will have to rely on changing their bodies or their behaviors.

D. It seems that the future world is going to be hotter than humans are used to.

E. Therefore, the negative effects of a warmer world are visible in these animals' bodies.

F. Such adaptations boost an animal's surface area relative to its body, helping it to release extra heat.

G. Similar trends are seen in mammals, with species of mice and bats evolving bigger ears, legs and wings.
