New Zealand is an island country in the southwestern of Pacific Ocean. The country geographically comprises two main lands—the North Island, or Te Ika-a-Maui, and the South Island, or Te Waipounamu, and numerous smaller islands. New Zealand is situated some 1,500 kilometers east of Australia across the Tasman Sea and roughly 1,000 kilometers south of the Pacific island areas of New Caledonia, Fiji, and Tonga. Because of its remoteness, it was one of the last lands to be settled by humans. The country's varied topography（地形）and its sharp mountain peaks, such as the Southern Alps, owe much to volcanic eruptions. New Zealand's capital city is Wellington, while the city that has the largest population is Auckland.

    Polynesians settled in the islands that were to become New Zealand somewhere between 1250 and 1300 AD, and developed a unique Maori culture. In 1642, Abel Tasman, a Dutch explorer became the first European to sight New Zealand In 1840, representatives of the British Crown（王室） and Maori Chiefs signed the Treaty of Waitangi, making New Zealand a British colony. Today, the majority of New Zealand's population of 4.5 million is of European descent(血统), and the indigenous(土著的) Maori are the largest minority, followed by Asians and Pacific Islanders. Reflecting this, New Zealand's culture is mainly originated from Maori and early British settlers, with recent broadening arising from increased immigration. The official languages are English, Maori and New Zealand Sign Language, with English predominant(主要的).

    New Zealand is a developed country with a market economy that mainly consists of the exports of dairy products, meat and wine, along with tourism. New Zealand is a high-income economy and ranks highly in international comparisons of national performance, such as health, education, economic freedom and quality of life.

    When my sister Mertie told me she had put out tomato plants last summer, I was quite impressed.

    Since she was a garden-beginner, Mertie researched exactly how far apart to space her tomato plants; what kind of fertilizer to use; how to keep away the bugs（害虫）, etc. Once they were planted, she took care of them daily, anxiously awaiting the juicy tomatoes to appear. But, day after day, her plants were tomato-less while all of her neighbors who had also put out tomato plants were already enjoying the fruit of their labor.

    Frustrated (upset), Mertie gave in and went to the market to search fresh tomatoes. While paying, Mertie told the farmer her troubles. The farmer paused to think for a moment and then asked, "Well, what kind of tomatoes did you plant?"

    "I think they were called Big Boy," Mertie remembered.

    "Well there's your problem," the farmer explained. "Big Boy and Better Boy tomatoes have a 95-day growing period whereas regular tomato plants produce fruit in as few as 70 days…you just have to wait a little longer for the Big Boys."

    With that new knowledge, Mertie went home with excitement, knowing they would be worth the wait.

    Thinking about my sister's gardening experience, I had to smile. She just didn't know that Big Boy tomatoes took longer--neither did I--but once she discovered that information, she was no longer discouraged and upset about the lack of tomatoes on her plants. Instead, she was encouraged and excited to see them a few weeks later.

    It makes me wonder how many of us have "Big Boy" dreams in our hearts, yet we just don't realize that they are of the "Big Boy" variety so we are discouraged and worn out with the waiting process. Instead of waiting with excitement, we give up on our dreams and figure we must have done something wrong to stop them from coming to pass. Frustrated, we see other people's dreams coming true, and we wonder why ours haven't yet been achieved.

    Many youths want to learn how to drive cars. This year one sixth of undergraduates in Beijing have registered at driving school. The students, mostly from majors such as business management or imitational trade, will finish their driving courses within 20 days or so.

    Training costs have dropped to 4, 500 yuan for students, according to the Haidian Driving School in Beijing. The price is not really low, but students will accept it, seeing it as an investment (投资) in their future. Familiarity with the operation of computers and fluent English are the basic skills graduating students need to find a job. But a driver s permit has become another factor (因素).

    "In the job market, owning a driver's permit sometimes strengthens a graduating student's competitiveness for a good position," says Li Hua, an undergraduate at the China University of Political Science and law.

    Cars will become a necessary part of many people's lives in the coming years, and it is difficult to get a permit out of campus because of the pressures on working people's time. "Having a full-time job after graduation offers limited time to learn to drive. We senior students have plenty of spare time, plenty of oppurtunity to learn," says another undergraduate at the university.

    Wu Dong, an official at the driving school, said undergraduates were very able and serious, and could grasp in an hour what ordinary people took four hours to learn. In this driving school, middle-aged people, young women and college students are the main customers.

    From March 1, 2018, to get a driver's permit, a beginner is now required to have at least 86 hours' practice before the final road test.

    One of the hardest parts of planning a trip to Hawaii is deciding which of the major Hawaiian Islands you should visit. Each has its own personality and offers unique adventures and activities.

    Oahu

    Oahu has a bit of everything, packed in 597 square miles. You can hike into thick rainforests, and when you need a break, relax on powdery white sand beaches and stay at luxury resorts.

    Oahu has become a great destination for families. The urban core (核心) of Honolulu and Waikiki has historic sites, museums and bustling (熙熙攘攘的) and nightlife scenes. The island lives up to its nickname of the Gathering Place.

    Maui

    Maui is a great island for honeymooners. The Valley Isle has top-class resorts and golf courses, adjacent (毗邻) to some of the state's best beaches. A large dormant (休眠) volcano in east Maui at sunrise or sunset is a serene experience, as well as driving the Road to Hana, famed for its thundering waterfalls.

    Kauai

    Kauai is the oldest of the main Hawaiian Islands. The island gets a lot of rain, but that's what makes it so lively, you'll come across flowers and plants you've never seen before. For some of the best views on the island, visit Waimea Canyon, known as the Grand Canyon of the Pacific, and the Na Pali coast, boasting some of the world's highest sea cliffs.

    Big Island

    The Big Island is the only Hawaiian island still growing. Witness the power of Pele, the Hawaiian goddess of fire, wind, lightning and volcanoes with a visit to the Hawaii Volcanoes National Park. It's one of the few spots in the world where you can see lava flow. In fact, the Big Island has 10 of the world's sub-climate zones, from the snow-covered mountain of Mauna Kea, green forests of Waipio Valley to stretches of barren desert.

    Scientists have created a scent(气味)-delivery system that releases a pleasant fragrance when you sweat. Apply it to your skin, and the more you sweat, the better you'll smell. That's because the perfume only gets released upon contact with moisture(湿气).

Chemists from Harvard University combined two compounds to create their new system. One chemical is alcohol-based. This is the nice-smelling perfume. The other chemical is an ionic liquid(离子性液体), which is a type of salt that is liquid at room temperature. Ionic liquids are made of ions—molecules(分子) that have lost or gained one or more electrons(电子). If the molecule loses electrons, it will have a positive charge(正电荷). If it gains electrons, it gets a negative charge. Ionic liquids contain the same number of positive and negative ions, which makes them neutral, with no overall electric charge. In general, ionic liquids have no smell.

    When the perfume and ionic liquid are mixed together, a chemical reaction occurs. This bonds the molecules to each other. The reaction also temporarily inactivates the perfume's molecules. So when applied to the skin, the new perfume has no scent in the beginning. But adding water or sweat breaks the bond between the molecules. That releases the scent into the air.

    "The rate of the release of the fragrance depends on how much you sweat, in other words, how much water is available," explains chemist Nimal Gunaratne from Harvard University, who led the research. "Sweat is like the command to let the fragrance go."

    Christian Quellet is a chemist who has worked in the perfume industry for a long time. He is now an independent consultant based in Switzerland. "Gunaratne's perfume opens the door to new developments and applications of fragrance controlled-release systems," he says. Controlled-release systems allow small quantities of some compounds that they hold to enter the environment slowly.

    The system also traps some chemicals in sweat that are responsible for the bad sweat smell. These compounds are called thiols (硫醇). Just as water does, thiols break apart the bond that ties the perfume to the ionic liquid. When this happens, the thiols attach to the ionic liquid and their bad scent is inactivated as the perfume had been. This means the water in sweat and its thiols are both able to release the fragrance from the newly developed perfume.

Coca-Cola is to test a paper bottle as part of a longer-term goal to get rid of plastic from its packaging entirely. The prototype(样本) is made by a Danish company from an extra-strong paper shell that still contains a thin plastic liner (衬垫). But the goal is to create a 100% recyclable, plastic free bot tle capable of preventing gas escaping from carbonated(碳酸) drinks. The barrier must also ensure no fibers get into the liquid. 

That may have a risk of changing the taste of the drink ——or potentially can't meet the requirements of health and safety checks. But industry giants (巨头)are backing the plan. Coca-Cola, for example, has set a goal of producing zero waste by 2030. Coca-Cola was ranked the world's number one plastic polluter by charity group Break Free From Plastic(摆脱塑料) last year, closely followed by other drink-producers Pepsi and Nestle. 

The Paper Bottle Company, or Paboco, is the Danish firm behind the devel-opment of the paper-based container. Part of the challenge has been to create a structure capable of standing the forces exerted by carbonated drinks —— such as cola and beer —— which are bottled under pressure. On top of that, the paper needs to be mouldable to create different bottle shapes and sizes for different brands and take ink for printing their labels. 

After more than seven years of lab work, the firm is now ready to host a trial in Hungary this summer of Coca-Cola's fruit drink Adez. Initially, this will in-volve 2, 000 bottles distributed via a local retail chain. 

But it is also working with others. Absolut, the vodka maker, is due to test 2, 000 paper bottles of its own in the UK and Sweden of its pre-mixed, carbonated raspberry drink. And beer company Carlsberg is also building prototypes of a paper beer bottle. 

Michael Michelsen, the firm's commercial manager, says the bottles are formed out of a single piece of paper-fiber-based material to give them strength.
