four-acre garden of dreams was designed by landscape architect kishore narshingh. most especially, the site was characterized by six pavilions, which symbolized the “six seasons” of nepal: spring, early summer, the summer monsoon season, early autumn, late autumn, and winter. in its most powerful time, the garden was considered one of the most remarkable feats of landscape design in the country.today, visitors will only find three pavilions on just over an acre of land, but the 74,000 square-foot space remains a fresh and green attraction. through the gardens original gates are pretty and old-fashioned fountains and ponds, isolated gardens of varying sizes, and the kaiser caf restaurant & bar. pathways are lined with grass, trees, and flowers from all over the world.while the garden of dreams has been transformed into a public space, it remains a quiet and peaceful escape in the center of kathmandu, and a popular hangout for sunbathers, wanderers, residents, and tourists alike.know before you gothe garden of dreams is open daily from 9 a.m. until 10 p.m. its located in the kaiser mahal complex in the busy thamel neighborhood of kathmandu. admission to the garden costs rs. 200 per person for tourists and rs. 100 for nepali residents. wifi is available throughout the garden for rs. 50 an hour.21. which item can tourists enjoy in the garden of dreams

country with six seasonsbamong the more colorful characters of leadvilles golden age was h.a.w. tabor. his history is fast becoming one of the legends of the old west. perhaps he was lured by rumors of fortunes to be made in colorado mines. a few years later he moved west to the small colorado mining camp known as california gulch. “great deposits of lead(铅) are sure to be found here.” he said.tabor opened a store, which sold everything from boots to salt, flour, and tobacco. it was his custom to “grubstake” miners, in other words, to supply them with food and supplies while they looked for ore (矿石), in return for which he would get a share in the mine if one was discovered.one day in 1878, two miners came in and asked for “grub”. tabor had decided to quit supplying it because he had lost too much money that way. these were continued, however, and tabor was too busy to argue with them. “oh help yourself. one more time wont make any difference,” he said and went on selling shoes and hats to other customers. the two miners took $17 worth of supplies, in return for which they gave tabor a one-third interest in their findings. they picked wasteland on the mountain side and began to dig. after nine days they struck silver. tabor bought the shares of the other two men, and so the mine belonged to him alone. this mine, known as the “pittsburgh mine,” made 1,300,000 for tabor in return for his $17 investment.later tabor bought the matchless mine for $117,000. this turned out to be even more incredible than the pittsburgh, yielding $35,000 worth of silver per day at one time. leadville grew. tabor became its first mayor, and later became vice-governor of the state.24. tabor went to colorado_.a. to seek fortune.b. to sell supplies.c. to open a mine company.d. to look for ore.25. what is tabors custom in his shop?a. sharing wasteland with miners. b. helping the miners to look for ore.c. supplyingeverythingtominersforfree.d. exchangingitemsforminerals interestswithminers.26. why didnt tabor give up the “grub” with the two miners?a. because he was specialized in business.b. because they insisted on making a deal with him.c. because the other customers prevented him then.d. because he had earned too much money before.27. whatis the intention ofthepassage?a. tointroducetaborssuccessful experience.b.toencouragepeopletostartabusiness.c. todiscusstabors lifeplanning.d. totellofthegoldrush. csome developed countries in the world have begun to shorten working hours. japan, on the other hand, has been in the culture of overwork. the problem is so severe that the country has even created a term for it: karoshi, which means death by overwork from stress-induced illnesses or severe depression. if the system of four-day workweek is tested in japan, what will happen?a growing number of smaller companies are adopting a four-day workweek. now the results of a recent trial at microsoft (msft) suggest it could work even for the biggest businesses.the company introduced a program this summer in japan called the “work life choice challenge,” which shut down its offices every friday in august and gave all employees an extra day off each week.the results were promising: while the amount of time spent on work was cut dramatically, productivity measured by sales per employee went up by almost 40% compared to the same period the previous year, the company said in a statement last week.in addition to reducing working hours, managers urged the staff to cut down on the time they spent in meetings and responding to emails.they suggested that meetings should last no longer than 30 minutes. employees were also encouraged to cut down on meetings altogether by using an online messaging app (microsofts, of course).the effects were widespread. more than 90% of microsofts 2,280 employees in japan later said they were impacted by the new measures, according to the company. by shutting down earlier each week, the company was also able to save on other resources, such as electricity.28. why is the idea four-day workweek tested in japan?a. becauseoverwork has caused serious problems.b. becausetheofficesmustbeshutdownonfriday.c. becausethestaffcangetextradaystoresteasily.d. becausesmallercompanieshavetakenthemeasure.29. whats the result of adopting a four-day workweek?a. it is a waste of energy.b. the workers earned less money.c. the working efficiency increases greatly.d. japans unemployment rate is barely rising.30. how can the time the staff spent on meetings be reduced?a.bycancellingmeetings.b.byusingemailstorespond.c.bycuttingdownworkinghours.d. byusingacertainonlinemessagingapp.31. what is the staffs attitude to the new measures? a. supportive.b. negative. c. critical.d. indifferent.dsydney australian scientists have designed a system which uses microwaves to break down plastic into an environmentally friendly by-product.head of electrical engineering at australias james cook university, prof. mohan jacob revealed on thursday that by using microwaves, plastic waste can be converted into biochar(生物炭), charcoal that can be used as a soil conditioner.“we are developing a processing room, which could process many kinds of plastic materials, up to 5 kilograms of waste,” jacob said. “it will be a typical example system for the development of biochars from different types of plastics under various conditions.” jacob explained that microwave energy is used to heat the plastic waste above 600 degrees centigrade within the custom-made room, where it ends up as a biochar, which can then be used to improve the properties of soil.currently underway is step one of the project, testing the room, after which, step two will involve improving the energy efficiency of the system and maximizing the yield of by-products. if all goes to plan, step three will be to construct a medium scale waste processing system which is customizable and can be installed remotely.jacob said that with the average person using 130 kg of plastic every year, there is an urgent need for developing better ways of processing it.“perhaps contrary to popular opinion, plastic is an indispensable material in modern life. it is cheap, competent, lightweight, and has many benefits like maintaining food quality and safety and preventing waste,” he said.however, “abandoned plastics endanger our marine wildlife, and have begun to enter the food chain. there is an urgent need for developing technologies to recover plastic waste.”32. how does the system function?a. microwaves are used to produce plastic.b. plastic waste is heated in the microwaves.c. plastic waste is cut into pieces and buried into the soil.d. microwaves change plastic waste into biochar by heating.33. which statement is true according to jacob?a. plastic consumption now is acceptable. b.plasticshouldbeabandonedinourlife. c.thesystemofprocessingplastichas come into use. d.findingbetterwaystodeal withplasticwaste isurgent.34. what does “recover” in the last paragraph mean? a. make up for a loss in time.b. find or regain lost possession.c. extract or recycle an energy source for reuse.d. return to a normal state of health, mind or strength.35. what does the passage mainly tell about?a. 3 steps of processing plastic waste.b. a way of producing plastic products easily.c. a new system of breaking down plastic waste.d. a program designed for plastic use in the daily life.第二节 (共5小题；每小题2分，满分10分)根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。a sea of decisions stretches before us and have a larger impact on our lives. were attacked with so many decisions that its impossible to make a perfect choice every time. however, there are many different ways to make it. 36 heres one 4-step process that may help you solve any number of problems:1. formulate your question. 37 this isnt always as straightforward as it sounds. but, if you approach the situation with a clear view of what youre actually trying to accomplish, thatll equip you to sift through this information critically and find what you are looking for. and you can decide whether the new fashion really suits your needs.2. 38 theres lots of it out there, so having a clear idea of your question will help you determine whats relevant. information gathering helps you weigh different options, choosing a decision that meets your goal.3. apply the informationsomething you do by asking critical questions. for example, in an email that promises you millions, you should consider: what is
