分析 據(jù)氣象專家說，他們非常擔(dān)心沙塵暴對人們健康的影響．

解答 答案：According to weather experts，they're quite concerned about the influence of sandstorms on people's health．

點評 本題考查句子翻譯，做此類題目時一定要根據(jù)中文及英文題干確定需要翻譯的成分，再找出與之對應(yīng)的英文并考慮各成分是否有形式的改變．

8．The United States estimates that about one out of every 10 people on the planet today is at least 60 years old．By 2050，it's projected to be one out of 5．This means that not only will there be more old people，but there will be relatively fewer young people to support them．
Professor Richard Lee of the University of California at Berkeley says this aging of the world has a great effect on economics．"Population aging increases the concentration of population in the older ages and therefore it is costly，"he said．
Aging populations consume （消耗） more and produce less．With more people living longer，it could get expensive．But Mr．Lee says with continuing increases in worker productivity and smart planning，it can be manageable．
Societies have different methods for caring for the elderly，but each carries a cost．Generally，there are three types of support．Seniors can live off the wealth they gained when they were younger．They can rely on their family to take care of them，or they can rely on the government．
In industrialized nations，governments created publicly-funded （公共資助的） support systems．These worked relatively well until recent years，when aging population growth in places like the United States and Western Europe began to gradually weaken the systems'finances．These nations now face some tough choices．Mr．Lee says the elderly in some of these countries must either receive less money，retire later or increase taxes to make the system continuable．
Most developing nations haven't built this type of government-funded support，but have instead relied on families to care for their elderly．These nations also generally have a much younger population，which means their situation is not as urgent as more developed nations．But Mr．Lee says that doesn't mean they can ignore the issue．"Third World countries should give very careful thought to this process，to population aging and how it may affect their economies-now，before population aging even becomes an issue，"he explained．
29．"Aging"in this text meansD．
A．there are more young people than old people
B．a(chǎn)n increasing number of old people are dying
C．more and more young people are growing old
D．the percentage of old people in the world is increasing
30．What is Professor Richard Lee's attitude towards population aging？B
A．Indifferent．
B．Negative．
C．Optimistic．
D．Worried．
31．The publicly-funded support systems in industrialized nationsA．
A．a(chǎn)re facing the risk of failing
B．have failed to provide support for the old
C．will be replaced by other support systems
D．have greatly affected the nations'economies
32．We can infer from the text that developing nationsB．
A．don't see population aging as an issue
B．should prepare for population aging．
C．a(chǎn)re facing urgent situations of population aging
D．have better ways to deal with population aging．

9．Nowadays the U．S．students are sleepy in school because they spend too much time texting，playing video games，watching TV and using the media in other ways．
"Heavy media use interferes with sleep by reducing sleep duration，making it harder to fall asleep，and lowering sleep quality，"Meilan Zhang，an assistant professor at the University of Texas at El Paso，wrote in her research review in the journal，Sleep Medicine．
But the relationship between youth's media use and sleep is not so simple，said Michael Gradisar，who authored both that review and the Sleep Medicine meta-analysis．"Technology use is the new evidence when we are trying to answer‘Why are school-age children sleeping less？'"said Mr．Gradisar，an associate professor of psychology at Flinders University in Adelaide，Australia．
There may be safe limits to technology use，Mr．Gradisar stated．For instance，recent research results indicate that using a bright screen for an hour before bed or even playing violent video games for less than that will not necessarily interfere with teenagers'sleep，he wrote．
But longer periods of usage can be harmful to sleep，Mr．Gradisar added．Rather than delaying school start times，he said，the first step should be educating parents about limiting the hours that their children are using technology before bed，and enforcing a consistent bedtime．
Early school start times are also commonly blamed for students'sleepiness，especially for adolescents．Secondary schools around the nation and the world have been delaying start times，often with positive results．
Mr．Minnich of the TIMSS and PIRLS International Study Center hesitated to put blame to any particular factor．But he did think that cost-saving measures to consolidate（合并）bus routes might help explain U．S．students'sleepiness．
"For those children who board the bus first，they must get up earlier，may end up sleeping on the way to school，and may end up arriving at school sleepy．"he said．

13．Which of the following may be the good way to help kids sleep better？C
A．Parents should be well educated．
B．Technology is forbidden at home．
C．Their playing time must be limited．
D．They are allowed to go to school early．
14．What would be the factors that cause kids sleep troubles according to the textC
a．Using the media．
b．Having breakfast．
c．Catching the bus．
d．The school timetable．
e．Doing too much homework．
A．a(chǎn)，d，e          B．b，c，d          
C．a(chǎn)，c，d          D．b，d，e
15．Which of the following may be the best title for the text？D
A．Kids benefit a lot from technology．
B．Several sleep troubles appear at school．
C．Some tips can help kids sleep well．
D．Several factors affect kids'sleep．

8．I am so appreciating my daughters today and all that we learned while we were growing together．I am especially grateful for the activities that centered on kindness and brought joy to us at the same time．
At one time we decided to bake bread for the homeless community（社區(qū)） on the beach near our home．We took 2days during each week to bake mini loaves of bread and also took cheese of each person．As this project went on （eventually for more than two years），one of my daughters started having short conversations with each person she gave bread to．
Eventually we brought some playing cards and checkers and played with some of the people，too．Soon several of our friends joined us and we began to make full lunches once a week for this community．
Years later when I saw one of the previous free lunch receivers，they would come up to me，share a nice memory from that time as well as how much the kindness meant to them and have some friendship with children，too．We had great fun together．
Both of my daughters，now grown with kids of their own，still take time to do kind things for others and community service projects and then share that with me．I am grateful for a focus away from self and to find real joy and purpose in being kind．
66．What did the author do？A

C．She baked bread for people around with kindness．
D．She purchased and gave out playing cards and checkers alone．
