1.Sabina Caste Franco Rome October 16,2011-The U.N.World Food program says there are growing concerns over food insecurity in the developing world.Some of those concerns are discussed in a report to agree with the anniversary Sunday of World Food Day.
The theme for World Food Day 2011is"Food Prices-From Crisis to Stability".A ceremony to mark World Food Day will be held Monday at the headquarters of the U.N.Food and Agriculture Organization in Rome.Rising food prices,weather emergencies and political instability are deepening the struggle of families trying to provide for their households in many developing nations.This year's"State of Food Insecurity in the World"report,published last week,focuses on the impact of food price volatility,confirming that high,unpredictable prices are likely to continue.The report highlighted how poor consumers,small farmers and countries dependent on imports,especially in Africa,have been deeply affected by the food and economic crises.
Gregory Barrow is with the World Food Program in Rome."If you look at the places where World Food program works particularly in developing countries,you see populations of people who might be spending 60,70,80percent of their salaries on purchasing food for their families".Barrow added that if prices become changeful and generally start rising,even by a small amount,it means that many of these people are going to struggle to put nutritious food on their tables.
The report also showed that even short-term fluctuations (波动) in prices can have a long-term effect on development,and that cutting back on nutritious food in the first 1,000days of a child's life can affect mental and physical development and finally,future earning capacity.The United Nations has programs in place aimed at reducing the number of hungry people by one-half by 2015.But most observers agree this target is unlikely to be reached.

2.In the Internet age,speed reading is a necessary and important skill.We skim over articles and e-mails to try to get key words and the main idea of the text.With so much information through our electronic devices (电子设备),it would be impossible to get through everything if we read word by word,line by line.However,a new trend calls on people to enjoy reading slowly.
A recent story from The Wall Street Journal reported on a book club in Wellington,New Zealand,where members meet in a café and turn off their smartphones.They sit back in comfortable chairs and read in silence for an hour.
Unlike typical book clubs,the point of the slow reading club isn't to exchange ideas about certain books,but to get away from electronic devices and read in a quiet,relaxed environment.According to the story,the Wellington book club is just one example of a movement started by book lovers who miss the traditional way of reading.
Traditional readers,like Maura Kelly,say a regular reading habit sharpens the mind,improves concentration,reduces stress levels and deepens the ability to understand others.Some of these benefits have been backed up by science.For example,a study of 300 elderly people published by the journal Neurology last year showed that adults who take part in activities that use their brain,such as reading,suffer less memory loss as they get older.Another study published last year in Science showed that reading novels helps people understand others'mental states and beliefs-a key skill in building relationships.
Yet technology has made us less careful readers.Computer and phone screens have changed our reading patterns from the top-to-bottom,left-to-right reading order we traditionally used,to a wild skimming pattern as we hunt for important words and information.Reading text online that has many links to other web pages also leads to weaker comprehension than reading plain text.The Internet may have made us stupider,says British journalist Patrick Kingsley,only half joking.Because of the Internet,he says we have become very good at collecting a wi de range of factual tidbits (花边新闻),but we are also gradually forgetting how to sit back,think and connect all these facts with each other.

A.no longer read word by word,line by line
B.have to get the meaning faster
C.have much more information to read
D.must use their smartphones more frequently

A.make coffee for the other members
B.read peacefully for an hour
C.regularly exchange ideas about books
D.turn off their smartphones for sleeping
27.According to the Neurology study,who is most likely to suffer memory loss?A
A.A 79-year-old woman who reads regularly.
B.A 17-year-old middle school student who seldom reads.
C.A healthy 24-year-old university graduate who often plays games.
D.A 65-year-old man who rarely reads.

3.When I first told people I was going to work in Cameroon,the most common reaction was:"Why?"The second was:"It's in Africa; you'll die!"The third:"Where is that?"So let me give some answers.I was offered a job that looked interesting in a part of the world I'd never been to before.I'd also long had an interest in Africa,so I decided it was time to find out the reality.
A small amount of research showed that in more than 40years since gaining independence,Cameroon has been a peaceful country with no wars.Not only are there no wars,but Cameroon is a food exporter to the region.
Now,after three years,I can say that these have been the healthiest years of my life!No malaria or any of the other frightening diseases you read about when Africa is mentioned.The worst thing that ever happened to me was a bout of food poisoning-once.
So what is it like to teach here?Well surprisingly not so different from teaching anywhere else.
Most students come to us with a bit of English in their heads.Cameroon is a bilingual country with French and English as official languages,while there are also close to 200local ethnic languages in a country of 16million people.French is the dominant language,spoken by about 80% of the population.
The local school system is very traditional and somewhat strict.Perhaps not surprisingly when there can be up to 150students in the classroom (of which maybe 30have the books,and there are probably seats for 70).
Like anywhere else,students appreciate it if you know a bit about their country,and not just Roger Milla (the top scorer of the 1990World Cup,in case you're wondering).It helps if you know the names of the ten provinces,know who the first president was,or can say a word in a local language.
So in conclusion:Cameroon isn't just football.Not is it war,poverty and disease.It's just life and people,like anywhere else.

29.On hearing the writer's decision,most peopleA.
A.didn't understand him  
B.considered it as a joke
C.admired him
D.laughed at him
30.According to the passage,Cameroon isB.
A.a country full of diseases
B.peaceful after liberation
C.a poor country,especially lack of food
D.quite different from others in education
31.What can we infer from the passage?C
A.Food export may lead to many frightening diseases
B.Most students in Cameroon do not need books
C.Cameroon is not as bad as people commonly believed
D.There must be a lot of people suffering from food poisoning.
32.What does the underlined word in the sixth paragraph mean?A
A.leading  B.easy  C.only  D.wonderful.
20.What time is it?Most people are pretty accurate in their answer.And if you don't know for sure,it's very likely that you can find out.There may be a watch on your wrist; there may be a clock on the wall,desk,or computer screen; or maybe you're riding in a car that has a clock in the dashboard(仪表板).
Even if you don't have a timepiece of some sort nearby,your body keeps its own beat.Humans have an internal clock that regulates(调节) the beating of our heart,the pace of our breathing,the discharge(排出) of chemicals within our bloodstream,and many other bodily functions.
Time is something from which we can't escape.Even if we ignore it,it's still going by,ticking away,second by second,minute by minute,hour by hour.So the main issue in using your time well is,"Who's in charge?"We can allow time to slip by and let it be our enemy(敌人).Or we can take control of it and make it our ally.
By taking control of how you spend your time,you'll increase your chances of becoming a more successful student.Perhaps more importantly,the better you are at managing the time you devote to your studies,the more time you will have to spend on your outside interests.
The aim of time management is not to schedule every moment so we become all slaves of a timetable that governs every waking moment of the day.Instead,the aim is to permit us to make informed choices as to how we use our time.Rather than letting the day go by,largely without our awareness,what we are going to discuss next can make us better able to control time for our own purposes.

33.The underlined word"ally"in Para.3most likely means somebody or something that isB.
A.your slave and serves you
B.your friend or supporter and helps you
C.under your control and obeys you
D.under your influence and follows you
34.The author intends to tell us that timeC.
A.could be regulated by a timepiece such as a clock or a watch
B.could be managed by the internal clock of human bodies
C.should be well managed for our own interest
D.should be saved for outside interests
35.In the next part,the author would most probably discuss with youD.
A.how to keep up with the times
B.how to make up for lost time
C.how to have a good time
D.how to make good use of time.
