Late-Night Drinking

根据内容回答题.

Coffee lovers beware. Having a quick "pick-me-up" cup of coffee late in the day will play havoc with your sleep. As well as being a stimulant, caffeine interrupts the flow of melatonin, the brain hormone that sends people into a sleep.

Melatonin levels normally start to rise about two hours before bedtime. Levels then peak be-

tween 2 a.m. and 4 a. m. , before falling again. "It&39;s the neurohormone that controls our sleep and tells our body when to sleep and when to wake," says Maurice Ohayon of the Stanford Sleep Epidemiology Research Center at Stanford University in California. But researchers in Israel have found that caffeinated coffee halves the body&39;s levels of this sleep hormone.

Lotan Shilo and a team at the Sapir Medical Center in Tel Aviv University found that six vol-

unteers slept less well after a cup of caffeinated coffee than after drinking the same amount of de- caf(脱因咖啡). On average, subjects slept 336 minutes per night after drinking caffeinated cof- fee, compared with 415 minutes after decaf. They also took half an hour to drop off—twice as long as usual--and jigged aroused in bed twice as much.

In the second phase of the experiment, the researchers woke the volunteers every three hours and asked them to give a urine sample, Shilo measured concentrations of a breakdown product of melatonin. The results suggest that melatonin concentrations in caffeine drinkers were half those in decaf drinkers. In a paper accepted for publication in Sleep Medicine, the researchers suggest that caffeine blocks production of the enzyme that drives melatonin production.

Because it can take many hours to eliminate caffeine from the body, Ohayon recommends that coffee lovers switch to decal after lunch.

A.decaf is a caffeinated coffee

B.coffee is a stimulant

C.neurohormone can wake us up

D.melatonin levels need to be raised

Climate Change Poses Major Risks for Unprepared Cities

A new examination of urban policies has been __________ (51) recently by Patricia Romero Lankao. She is a sociologist specializing in climate change and __________ (52) development. She warns that many of the world&39;s fast-growing urban areas, especially in developing countries, will likely suffer from the impacts of changing climate. Her work also concludes that most cities are failing to __________ (53) emissions of carbon dioxide and other greenhouse __________ (54). These gases are known to affect the atmosphere. "Climate change is a deeply local issue and poses profound threats to the growing cities of the world," says Romero Lankao. "But too few cities are developing effective strategies to __________ (55) their residents."＜br＞

Cities are __________ (56) sources of greenhouse gases. And urban populations are likely to be among those most severely affected by future climate change. Lankao&39;s findings highlight ways in which city-residents are particularly vulnerable, and suggest policy interventions that could offer immediate and longer-term __________ (57).＜br＞

The locations and dense construction patterns of cities often place their populations at greater risk for natural disasters. Potential __________ (58) associated with climate include storm surges and prolonged hot weather. Storm surges can flood coastal areas and prolonged hot weather can heat __________ (59) paved cities more than surrounding areas. The impacts of such natural events can be more serious in an urban environment. For example, a prolonged heat wave can increase existing levels of air pollution, causing widespread health problems. Poorer neighborhoods that may __________ (60) basic facilities such as drinking water or a dependable network of roads, are especially vulnerable to natural disasters. Many residents in poorer countries live in substandard housing __________ (61) access to reliable drinking water, roads and basic services.＜br＞

Local governments, __________ (62), should take measures to protect their residents." Unfortunately, they tend to move towards rhetoric __________ (63) meaningful responses, Romero Lankao writes," They don&39;t impose construction standards that could reduce heating and air conditioning needs. They don&39;t emphasize mass transit and reduce __________ (64) use. In fact, many local governments are taking a hands off approach." Thus, she urges them to change their __________ (65) policies and to take strong steps to prevent the harmful effects of climate change on cities.＜
