2、eater chances for birds to feed their young.The longer daylight hours and enormous food resources allow birds to lay larger eggs than those of related non-migratory species that remain in the tropics all year round.As the days shorten in autumn and the breeding period is over,the birds return to war
3、mer regions where the available food supply differs little with the seasons changing.The advantages of migration make up for the high stress,physical exertion(消耗),and other risks of the migration.Day length is the primary environmental factor that encourages birds to prepare for migration.They have
4、an increased appetite which results in weight gaining,giving them the fat reserves that provide energy for their migratory flight.They also show more activity at night,which is when most birds migrate.While the length of day is the primary reason for migration,birds also respond to temperature chang
5、es.For example,if a spring is late and the temperature is lower than normal,birds delay migration;if a spring is early,birds also begin migration early.The timing of the migratory cycle must allow birds to arrive on the breeding site so that there is time tobuild a breeding place,mate,lay the eggs,a
6、nd hatch the young before the rich food is available to feed the young in the nest.Similarly,if birds wait until the climate in their northern breeding grounds becomes tolerable(可忍受的),there will be no time togain the necessary weight that provides the energy needed for their southbound migration.1.W
7、hy do birds migrate to the north in spring?A The temperature in the south has risen.B.They like traveling and enjoy the journey.C.The summer there is warmer than that in the south.D.The environment there is more suitable for them to feed their baby birds.2.What are the two factors that cause birds t

9、eginning of the decade of the yold,or the“young old”,as the Japanese call people aged between 65 and 75.The traditional retirement age is 65.One might therefore expect peak retirement.By continuing to work,and staying socially engaged,the yold will change the world,as they have done several times be
10、fore at different stages of their lives.The yold are more numerous,healthier and wealthier than previous generations of seniors.The yold are busier,too.In short,the yold are not just any group of old people.They are challenging the traditional expectations of the retired as people who wear slippers
11、and look after the grandchildren.That will influence consumer,service and financial markets.The over-60s are one of the fastest-growing groups of customers of the airline business.The yold are vital to the tourism industry because they spend much more,when taking a foreign holiday,than younger adult
12、s.But for all this to happen,three big things will have to change,under pressure from the yold themselves.The most important is public attitudes towards older people,and in particular the expectation that the old ought to be putting their feet up and quietly retiring into the background.Then,governm
13、ent policies will have to change,too.The retirement age in many rich countries is still below the age to which many people want to work.The effective retirement age(the age at which people actually leave the workforce)is usually even lower.Third,higher numbers of healthy yold people will require dra
14、stic changes in health spending.Most diseases of ageing are bestmetwith prevention and lifestyle changes.But only about 2%3%of most countries health-care spending goes on prevention.That will have to rise,because although the yold will constitute a bulge of comparative health and activity over the n
15、ext decade,by 2030 they will hit 75 and enter a long period of decline for which few rich countries are ready.4.What kind of people are the yold exactly?A.They are workaholics.B.They are full of energy.C.They enjoy being focused on.D.They like staying socially engaged.5.Why do the yold contribute to
16、 tourist industry?A.They like traveling more.B.They have more money.C.They consume more on travel.D.They have much free time.6.Whats the authors attitude toward health-care spending on prevention?A.Unsatisfied.B.Subjective.C.Neutral.D.Active.7.What does the underlined word“met”in the fourth paragrap
17、h mean?A.dealt with B.come across C.satisfied D.experienced.C Last year,138,000San Franciscoresidents used Airbnb,a popular app designed to connect home renters and travelers.Its a striking number for a city with a population of about 850,000,and it was enough for Airbnb to win a major victory in lo
18、cal elections,asSan Franciscovoters struck down a debatable rule that would have placed time restrictions and other regulations on short-term rental services.The company fiercely opposed the measure,Proposition F,with a nearly$10 million advertising campaign.It also contacted its San Franciscan user
19、s with messages urging them to vote against Proposition F.Most people think of Airbnb as a kind of couch-surfing app.The service works for one-night stays on road trips and longer stays in cities,and it often has more competitive pricing than hotels.Its a textbook example of the“sharing economy”,but
20、 not everyone is a fan.The app has had unintended consequences inSan Francisco.As the San Francisco Chronicle reported last year,a significant amount of renting on Airbnb is not in line with the companys image:middle-class families putting up a spare room to help make ends meet.Some users have taken
21、 advantage of the service,using it to turn their multiple properties into vacation rentals or even full-time rentals.Backers of Proposition F argued that this trend takes spaces off the conventional,better-regulated housing market and contributes to rising costs.“The fact is,widespread abuse of shor
22、t-term rentals is taking much needed housing off the market and harming our neighborhoods,”said ShareBetter SF,a group that supported Proposition F.Hotel unions have protested the companys practices inSan Franciscoand other cities,saying that it creates an illegal hotel system.San Franciscois in the
23、 middle of a long-term,deeply rooted housing crisis that has seen the cost of living explode.Actually,explode is a generous term.The average monthly rent for an apartment is around$4,000.Located on a narrow outcropping of land overlooking the bay,San Franciscosimply doesnt have enough space to accom
24、modate the massive inflow of young,high-salaried tech employees flocking toSilicon Valley.As the Los Angeles Times reported,someSan Franciscoresidents supported the measure simply because it seemed like a way to check a big corporation.Opponents of Proposition F countered that the housing crisis run
25、s much deeper,and that passing the rule would have discouraged a popular service while doing little to solve the citys existing problems.8.The intention of Proposition F is to _.A.place time limits in local election.B.set limits on short-term rental.C.strike down a controversial rule.D.urge users to
