Kiwis are unique in a lot of interesting ways.They have many characteristics that are not found in any other bird.
It is assumed that the kiwi's ancestor was able to fly and reached New Zealand.Once on the island，it lost its ability to fly and eventually became the kiwi known today.Kiwis have feathers that look like hair and very strong and muscular legs.They rule the ground instead of the air.They can smell very well.Kiwis are quite shy and usually only come out at night.Kiwis can live a long time，between 25 and 50 years.
A female kiwi carries a huge egg about its body size.The kiwi is about the same sizse as a chicken but its egg is actually six times as large as a chicken's egg.The reason for this is that the kiwi doesn't have to fly，so there aren't any limits on its weight.The female has to eat three times as much as usual to help the egg develop.Right before the egg is laid she can't eat anything because the egg presses against her stomach，leaving no room for food.
All kiwi species are endangered.On average，twenty-seven die each week.They have been affected most by deforestation and invasive mammals.Before humans came to New Zealand，the only mammals on the island were bats and seals.The kiwi never had to worry about predators before，but now since it cannot fly，and lays its eggs on the ground，it is pretty defenceless against invasive mammals such as rats and jye.ai.Stoats kill a lot of the chicks，while dogs kill a lot of adult birds，usually by accident，because they are quite delicate（脆弱的）.

1．Hi Judy!
You often complain to me that you always buy goods unreasonably on sale promotion（促銷）and feel it shameful after going back to your school dormitory with new things not needed，considering all the money you spend is your parents' income．
In fact，this is a common phenomenon，called impulsive buying，a buying unplanned and hard to control．It usually happens when a store offers discounts（打折）or sales promotion-a special way used by stores to get more customers，which means you may fall into its traps even without notice．
Stores，with a good knowledge of customers' psychology（心理），make use of it to drive business．Avoiding all the impulsive buying is a hard thing．However，knowing our psychology behind it and reducing the times when influenced by sales promotion may be useful．So you should keep calm when facing the sales promotion by keeping in mind what you really need．
Find out the conditions where you are likely to buy things blindly．When seeing a dress advertised at 20% off，do not concentrate on the discount，but warn yourself against falling into the trap of "saving money''．
Besides，do not forget the long-term effects of your choice when meeting a sales promotion．Short-term benefits，like excited feeling just after buying items encourage impulsive buying．But the long-term costs such as waste of money and the sense of shame really annoy you．When seeing the advertisements，remember what you really want to buy originally and warn yourself of that terrible feeling．Only in this way can you save money for really needed things．
Yours，
Rachel

3．Ever since I graduated from high school I've worked in the factories surrounding my hometown every summer.However，making the transformation between school and full-time blue-collar work during the break never gets any easier.For a student like me who considers any class before noon to be unacceptable，getting to a factory by 6 o'clock each morning is suffering.My friends never seem to understand why I'm so relieved to be back at school or that my summer vacation has been anything but a vacation.
There are few people as self-confident as a college student who has never been out in the real world.People of my age always seem to overestimate the value of their time and knowledge.In fact，all the classes did not prepare me for my battles with the machine I ran in the plant，which would jam whenever I absent-mindedly put in a part backward or upside down.
The most stressful thing about blue-collar life is knowing your job could disappear over night.Issues like being laid off and overseas relocation had always seemed distant to me until my co-workers told me that the unit I was working in would shut down within six months and move to Mexico，where people would work for 60 cents an hour.
After working 12-hour shifts（輪班）in a factory，the other options have become only too clear. "This job pays well，but it's hell on the body，" said one co-worker. "Study hard and keep reading." she added.When I'm back at the university，skipping classes and turning in lazy re-writes seems too irresponsible after seeing what I would be doing without school.All the advice and public-service announcements about the value of an education that used to sound stale（陳腐的）now ring true.
My experiences in the factories have inspired me to make the most of my college years before I enter the real world for good.
