    Once Chinese students in American schools were largely limited to graduate students. Gradually that trend shifted, with more students coming from China to earn bachelor' s degrees at American institutions. Now, the population is widening once again, with many Chinese students studying in the U, S. from ever - younger ages.

    Bill Zhou, a resident of California, though born in Shenzhen, and his wife are currently housing just such a student: Hsu, also from Shenzhen, who is living with Zhou (a paid arrangement) while he attends a private, religious institution. .

     Although Zhou is caring, he knows there are many people taking advantage of the trend

who lack conscience. In a Lost Angeles Times article, Zhou described his reservations about the current system.”They don't know if the school is good. They don't know if the home stay is good. But everyone else is doing it, so they do it, too," Zhou said, addressing the parents of so - called parachute(降落伞) children, who earn the nickname by "parachuting" into the U.S. by themselves, unaccompanied by family.

    Based on statistics, Zhou has reason to be concerned. A recent article in Sixth Tone', stated that the number of Chinese students enrolled at U. S. secondary schools increased from just 647 in 2006 to more than 46,000 in 2016. Those numbers are reflected in Chinese society and even popular culture, where a new television drama titled " A Love for Separation" was released several months ago.

    "It is a common misunderstanding that studying in a private American high school is easier than in China, a mother told. " My son is under enormous pressure to compete with accomplished peers. He was very lonely during his first year of high school, and found it hard to assimilate into an unfamiliar environment. "

     Chinese parents send their teenagers abroad for varieties of reasons. For some students, it is to escape the strict Chinese education system; for others, it is a second chance to recover from bad grades or a low score on China's college entrance exam. For still others, it is simply a lifelong dream.

    There is an island called Kitava, way out there in the Pacific Ocean, in the Milne Bay Province of Papua New Guinea. It is one of the four main Trobriand Islands with a total population of 12,000 native residents.  Rich with culture, surrounded on all sides by clear blue water and abundant rainforest, Kitava is as apealing as it is remote.  But it has more to offer than good views.

    As Byrdie reports, Kitava is also home to a people whose diet and nutritional habits remain healthy, untouched by Western influence.  A lifetime of not knowing the sweet, sweet sensation of the salt from a potato chip hitting the roof of your mouth has done more than just spare Kitavans from illnesses like diabetes and cardiovascular disease; it's also given them a lifetime of smooth, acne(痤疮) - free skin.

    In a study of l',200 subjects - including 300 teens and young adults - conducted by a team led by medical doctor and professor Steffan Lindeberg over 843 days, not one breakout was reported. They also found that genetics played little to no role in the results.

     In fact, the average Kitavan diet is fairly common. It' s simple, with no " miracle fruit" or " rare nut" to speak of, and Kitavans don' t even exercise much. That diet consists mainly of yams( 山荮) ,  sweet potatoes,  and taro (芋头) , local fruits (namely coconut) ,fish, and vegetables.

    But if you're already pulling out your suitcases and drafting a resignation letter to your boss, you might want to slow your step.  For one thing, the closest airport is over 700 miles away from the island, so good luck getting there. And consider this: do you really want to move somewhere where you'll be the only person with acne until the diet kicks in? I don't think so.

28. Which are the contributing factors of attracting visitors to the island?

    a. Rich culture .    b. Clean white sand     c. Thick rainforest  

d. Clear blue water  e. Romote tribes

      A. abc       B. acd         C. bcd        D. ade

    29. What accounts for the fact that the Kitavans own good skin?

       A.  They don't like eating salt. .          B.  They enjoy varieties of rare fruits.

       C. They are sick of exercising.      .     D. They follow simple but healthy diet.

    30. What is unlikely to be included in the Kitavans' diet?   .

        A. Taro            B. Fish              C. Potato chips        D. Coconut

     31. What can we learn from the last paragraph?

        A. Think twice before moving to Kitava.

        B. Don’t hesitate to quit your job and move there.

        C. One can reach Kitava by plane without difficulty.

        D. Anyone will own acne - free skin on stepping on Kitava.

Are you still worried about overcharging for your luggage over the weight limit? An " Airport Jacket" containing up to 15kg luggage is designed to help frequent flyers bypass(绕过)  airport baggage queues, reduce baggage fees and really lower the risk of lost luggage.

    " With airlines beginning to charge for carry - on baggage as well as severely limiting 10aggage allowances for the low fare economy traveler, my partner and I have designed a jacket that can wear your laptop,  tablet,  two pairs of shoes,  a pair of jeans,  five T - shirts, a jumper and a camera," designer Claire Murphy explains.  "It totals 14 deep pockets, including 8 pockets at hip length, 11 pockets at three - quarter length and 14 pockets at full length. "

    . Claire and Benke Murphy came up with the idea while traveling home with their newborn child. They had so much extra carry - on luggage that the airline tried to charge them $ 140 for it, more than the cost of their tickets.  So they had to put clothes, chargers, diapers and toys into their pockets, until just over the weight limit.  They escaped the tax, but everything sticking out of their pocket saw a pretty uncomfortable plane ride.

     However, people have been raising questions about the usefulness of the Airport Jacket, especially the trouble of going through security checkpoints. They are arguing that having to take all out and then putting them back into the pockets is not worth the few tens of dollars you save on a checked luggage.

     But Benke claims that walking through airport security is not an issue as long as you follow guidelines for carry - on luggage. " It only needs to be worn when checking in and at the boarding gate. What' s more, Airport security is not looking at how you store your luggage but checking its contents. "

    Its makers are currently running a crowdfunding campaign on Kickstarter, trying to raise  $ AU100, 000. But they've only raised $ AU3, 675 so far, although they still have 37 days to go, so it's still hopeful And even if this fails, they may still find a way to get it to market.

32.  What's the least possible benefit of using the Airport Jacket?

     A. it may cut down on the luggage fees.

      B.  it may decrease the risk of losing luggage.

      C.  it may save the time of passing long queues.

      D.  it can guarantee you a comfortable flight service. .

    A. how much luggage the couple carried

    B. how luckily the couple avoided overcharging

    C. how the designers got their inspiration

    D. how painful the couple's flying experience was

34. What can we infer from this passage?

    A. The pockets of the 'Airport Jacket have 28 in total.

    B. Not all regard the Airport Jacket as a perfect invention.

    C. Crowdfunding is the best way to collect money you need.

    D. Airports now begin to limit the number of economy travelers.

35. What will the author probably mention in the next paragraph?
