12.(8分)Germans have a word "wanderlust",which translated into English would be the desire

to wander.Nowadays the opportunity to travel is endless.Thanks to cheap air tickets,travelling all over the world is very accessible and sometimes it's even cheaper to fly out of the country than to travel within your own.

I have always had this feeling of wanderlust.As a young girl it started from me wanting to explore my local woods at the back of my garden and as I have grown,so has my sense of adventure.And I found my local woods being replaced with the Brazil wetland,Pantanal,where I went last summer in search of jaguars,snakes and crocodiles.

The thing with travelling is always different.Even if you went to the same country,to the same town and stayed in the exact same house,it would be a completely different experience.The people you meet will be different,and they will tell you their own travelling stories;stories of holiday romances,holiday horrors and stories that appear so suspect that you can barely believe them until something ridiculous happens to you and you find yourself becoming one of those people telling your tales.Or maybe the difference is yourself.When you travel you are forced to be in harmony with a new culture.Whether it's eating guinea pig,or staying with a family,where neither of you speak a common language and you have to communicate through hand movements and smiles,the experience gives me itchy feet to do it all again.And although wanderlust is originally a German word,the English idiom reflects a similar idea.Someone with that needs to leave or travel.This desire to explore is found not only in language but in us.

(1)Why is the Brazilian wetland mentioned in paragraph 2?

A.The author's garden lies near it.

B.It's similar to the author's hometown.

C.It's the desirable place for travel lovers.

D.The author intends to share her nature.

(2)What do we know from paragraph 3?

A.There are many ridiculous travel stories.

B.Travel can change the way people view things.

C.The author prefers to go to the same country.

D.It's interesting to know local culture and people.

(3)What does the author mean by the underlined sentence in paragraph 4?

A.She feels the urge to take a tour once more.

B.The situation leaves her much discomfort.

C.Her feet feels too tired when she is abroad.

D.The experience makes her lose confidence.

(4)In which section of a website can we read the text?

A.Hobbies of the Germans

B.Life around the world

C.Fashion on the earth

D.City tours and tips

13.(8分)Studying the DNA of 300 mice has flagged up genes which have been linked to hereditary (遗传的)sight loss for the first time.Researchers say because mice's genes are so similar to humans',their findings could result in the treatment of more genetic diseases.Scientists at the University of California,Davis studied information from a data bank of mice's genetic material.They found 347 genes linked to eye problems,with just 86 of them having been studied in the past.

Only around 50 to 75 percent of hereditary eye diseases in human can be accounted for with present science.The researchers believe these hundreds of new genes found in mice could be a key to explaining﹣﹣﹣and therefore being able to treat the other 25 to 50 percent."This is extremely valuable for people with hereditary eye disease," said researcher Professor Ala Moshiri."All researchers are going to start using these data.In the past,we knew the problem was there but we didn't know where to look.Now eye centers can call back patients and screen them for these new genes.We expect that more and more of these genetic diseases will be treatable." Also,the fact is that more than 60 percent of eye problems at birth are ones resulting from the baby's parents!

Thanks to data from the International Mouse Phenotyping Consortium (IMPC),which is trying to work out what every single gene in a mouse is responsible for,with the aim of translating it to humans,scientists are moving closer to figuring out all genetic causes of blindness.To do this,scientists separate a single gene from other ones at a time and then observe what effect it has on the mouse for a long time.This has so far been done more than

7,000 times and has achieved great success.Researchers are now working alongside eye care centers in Texas and Iowa in order to compare the mice's genes to those of patients.

(1)How many hereditary﹣sight﹣loss﹣related genes were newly found?

A.86.

B.261.

C.300.

D.347.

(2)Why is the percentage of genetic eye problems mentioned in paragraph 3?

A.To show the significance of studying mice's genes.

B.To prove mice's genes are similar to humans'.

C.To warn the high risk level of suffering them.

D.To explain how common they are among people.

(3)What should scientists do first to unlock secrets of genetic blindness?

A.Compare humans' genes with mice's.

B.Recognize each gene's role of humans.

C.Set apart a gene of a mouse each time.

D.Figure out each gene's function of a mouse.

(4)What can be a suitable title for the text?

A.New Ways to Cure Sight Loss

B.Genes Found Behind Eye Problems

C.Genetic Diseases Discovered in Mice

D.Humans Genes Causing Eye Diseases

14.(8分)Research indicates that some orchestral(管弦乐的)instruments are in danger of dying out.YouGov research,asked by the Royal Philharmonic Orchestra (RPO)to find the most popular instruments among schoolchildren,has revealed the increasing popularity of the ukulele (尤克里里琴),with one in eight expressing a desire to learn,making it the highest ranked instrument behind the typical rock﹣band grouping of the guitar,piano,keyboards,drums and bass guitar.

But younger generations' interest in "more complex instruments" is decreasing,with the

three least popular being the French horn,the double bass and the trombone.James Williams,managing director of the RPO,believed the changes reflect the increasing pressure schools are under to provide music education,and went on to say that more needs to be done to interest secondary school students in the wider range of instruments.His concern was for the composition of future orchestras ,should the trend towards instruments like rock﹣band grouping be allowed to continue.But there may be yet another death,one that few would be quick to sorrow over:the recorder (竖笛).Cheap,convenient,easy to learn,and suitable for individual and group performances,the recorder was once the go﹣to instrument for children's early musical education.But in many schools it has been replaced by the ukulele,which,for teachers,offers many of the same benefits with none of the lasting damage to hearing.Plus,from a student's viewpoint:you can play Metallica on one.

Not all hope is lost for the cream﹣colored,10﹣pound Yamaha recorder with a long history,however.About 13% of girls and 4% boys surveyed by YouGov said they wanted to learn the recorder.Surprisingly high! Unlikely as it may be,these children's interest in the recorder must be inspired.

(1)What does YouGov research suggest?

A.Schoolchildren determine the popularity of music.

B.The ukulele is the most popular with students.

C.Students generally prefer rock﹣band instruments.

D.Orchestral instruments will disappear in the future.

(2)What can we do to save orchestral instruments according to Williams?

A.Stop teaching children to play rock and roll.

B.Find means to inspire students' interest in them.

C.Spend much more school time on music education.

D.Offer free orchestral instruments to the public.

(3)Why has the ukulele replaced the recorder widely?

A.Because users can enjoy more advantages from it.

B.Because the music played on it is more appealing.

C.Because it is much cheaper and easier to learn.

D.Because it stands for the world's music tendency.

(4)What does the author stress in the last paragraph?

A.Many children choose recorders as expected.

B.It's time for younger learners to save music.

C.We should respect children's choices for instruments.

D.Recorders still have the potential for a bright future.

Healthy See,Healthy Do

Visit the grocery store on an empty stomach,and you will probably come home with a few things you did not plan to buy.But hunger is not the only cause of additional purchases.The location of store displays also influences our shopping choices.(1)The checkout area is a particular hotspot for junk food.Studies have found that the products most commonly found there are sugary and salty snacks.(2) A 2019 study in the Netherlands found that hospital workers were more likely to give up junk food for healthy snacks when the latter were more readily available on canteen shelves,for example.In 2019 Norwegian and Icelandic researchers also found that replacing unhealthy foods with healthy ones in the checkout area significantly increased last﹣minute sales of healthier foods.

(3)It has been working with more than 1,000 store owners to encourage them to order and promote nutritious foods."We know that the stores are full of cues (暗示)meant to encourage consumption," says Tamar Adjoian, a research scientist at the department,"Making healthy foods more convenient or appealing can lead to increased sales of those products."

Adjoian and her colleagues wondered if such findings would apply to their city's crowded urban checkout areas,so they selected three Bronx supermarkets for their own study.(4)Then they recorded purchases over six three﹣hour periods in each store for two weeks.Of the more than 2,100 shoppers they observed,just 4 percent bought something from

the checkout area.Among those who did,however,customers in the healthy lines purchased nutritious foods more than twice as often as those in the standard lines.(5)The findings were reported in September in the Journal of Nutrition Education and Behavior.The potential influence may seem small,but Adjoian believes that changing more checkout lines would open customers' eyes to nutritious,lower﹣calorie foods.Health department officials are now exploring ways to expand healthy options at checkout counters throughout New York City.

A.These foods give people more energy.

B.They bought unhealthy foods 40 percent less often.

C.And it may make or break some healthy eating habits.

D.The supermarkets began to offer nutritious,lower﹣calorie foods.

E.These findings caught the attention of New York City Department of Health.

F.They replaced candies and cookies with fruits and nuts near the checkout counter.

G.And a few studies have suggested that simply swapping in healthier options can shift customer behavior.

16.(30分)It was late,about 10:15 p.m.,when Janice Esposito arrived at the Bellport train station;she jumped into her Honda Odyssey and began the 20﹣minute drive home to her husband.She'd just returned from visiting her mother and had traveled the route many times before.She practically(1)on autopilot:a left onto Station Road,then a left on Montauk Highway,and then﹣wham!

"The gates were starting to come down," he told Newsday."I see the headlight of the train." DiPinto ran quickly to Esposito's minivan and knocked on the driver's side window.She (12)looked at him,her eyes unfocused."I don't know where I am," she said.She seemed unhurt."Honey,you're on the railroad(13)," DiPinto shouted."We have to get you off right now!" He pulled hard on the(14),but the door was crashed in and(15).The heavy diesel train,traveling at 65 miles per hour,was moving fast toward them.DiPinto ran to the passenger side and threw open the (16)."Please,don't let her be(17)," he thought.He pushed aside the deflating (瘪了的)airbags,grabbed Esposito's arms,and(18)her toward him across the passenger seat until he could help her out and quickly get her to(19)behind a signal box a few feet away.Within six seconds,he estimated,the train crashed into the minivan."It was like a Hollywood movie," DiPinto told reporters the next day.But this one had a twist."Last night," South Country Ambulance chief Greg Miglino told CBS New York,"the(20)arrived in pajamas,not in a fire truck."

The idea of quarantining sick people dates(5)ancient times.Yet the word "quarantine" first came into use in the 14th century Europe during the Black Death.People were dropping like flies from the mysterious disease,and as the death toll climbed into the millions﹣eventually killing(6)(approximate)half of the European population,cities began to take(7)(measure)to protect their citizens.The port city of Venice,Italy,was an important trading center with ships(8)(come)from all corners of the Earth every day.If a ship(9)(suspect)to be harboring the plague (瘟疫),it was sent to an offshore quarantine place and ordered to wait there for 40 days when those

abroad either recovered,or(10)(likely),died.The waiting period gave rise to the term quarantinario,from the Italian word for 40.

After graduating from high school,I'm going to be computer programmer,which I think is on great demand in the modern world.Moreover,my parents would like me to study medicine.They believe here are two reasons for being a doctor.One is that doctors usually deal with patients in person,which mean they are able to help people in need directly.The other is that doctors are so importantly that it is almost impossible for it to lose jobs.Up to now I have chatted with my parents for three time.To my disappointment,I was failed to persuade them.Now I am confusing about how to solve the problem.

黑龙江移动通信行业媒体广告费用分析报告

黑龙江移动通信行业媒体广告季度分析报 告 2003年第一季度 哈尔滨海润国际广告公司信息中心

目录 一、通信行业第一季度广告总费用比较 二、通信行业电视、报纸、广播媒体广告总费用比较 (一)、中国移动 (二)、中国联通 (三)、小灵通 三、电视部分 (一)、通信行业一季度电视广告费用比较 (二)、通信行业一季度哈市电视媒体比较 (三)、中国移动一季度哈市电视媒体各业务项及频次比较四、报纸部分 (一)、通信行业一季度报纸广告费用比较 (二)、通信行业一季度报纸媒体各项业务费用及频次比较 1、中国移动 2、中国联通 3、小灵通 (三)、通信行业各业务项排序 (四)、通信行业一季度哈市报纸媒体比较 1、中国移动 2、中国联通 3、小灵通 五、广播部分 (一)、通信行业一季度广播广告费用比较 (二)、通信行业一季度哈市广播频次比较

总结 1、各通信公司的广告费用支出呈递减趋势,一月份为年前时段,所以各通集团均抓住这一时机做重点宣传。 2、中国移动一直以信号好作为自己的主流业务,贯穿于第一季度,树立了中国移动信好的品牌形象。而在不同的月份中国移动相继推出了不同的业务项目,业务宣传内容多、宣传周期短、交替发布、记忆点不突出。 3、中国联通各业务项虽然也比较繁多,但其能突出重点,做到每个月都有自己突出宣传品牌,且宣传周期长,自身业务的干扰度小。 4、各通信集团之间竞争激烈,小灵通上市不久,联通即推出小神通;二月份中国移动神州行亲情号码推出以后,中国联通便针对其推出了如意通亲情号码。 5、小灵通业务一直以来遵循单一,循序渐进的原则。一月份小灵通上市期,其便以上市为重点宣传;二月份则以自己的内容宣传为主;三月份小灵通在黑龙江已基本上市,小灵通便在内容介绍的同时加强形象宣传。
