Many people cannot start their day without first having a cup of coffee or tea.These drinks help them think clearly and feel more awake.This is because of caffeine,which helps to give a jump start to the nervous system.Now,a report says it may also boost long-term memory.
Mike Yassa is a neurobiology professor.He and other researchers wanted to know if caffeine could improve a person’s memory.He explains,“After you learn anything,it takes some time for that memory to strengthen.And over the first 24 hours is actually where most of the forgetting happens.So that is where we wanted to intervene with caffeine and see if we can help reduce this forgetting.”
They took 160 caffeine-free people and showed them pictures of everyday objects. These people were asked if the objects could be found inside the house, or outdoors.Then some of the subjects were given a caffeine pill.The others were given a placebo—a pill containing nothing. 24 hours later,the subjects were shown the exact same images from the day before.They were also shown images with slight differences,and some completely new images. Both groups correctly identified the exact same and completely new pictures.But those who took the caffeine pill were better at spottingthe pictures that were slightly different.
Professor Yassa says their answers helped to show the effects of caffeine on memory. And we find that if they are on caffeine they are much more likely to make the right decision.”
The amount of caffeine the researchers used in the study was similar to one cup of strong coffee.The researchers did not see any improvement to memory from smaller doses of caffeine or when it was given an hour before viewing the images.

Many people in high school cannot wait to go to college and leave their hometowns behind.Questions arise, though,when it comes to all of the decisions involved in choosing a college.
One of the first considerations may be financial.State and public colleges are often the least expensive. Often, though,the better colleges are private and more expensive.It is sad when gifted students cannot attend a college of their choice just for financial reasons.
Another major factor is location.Whether the college is in a small town or large city can have a major impact on its activities.A water lover probably will be more comfortable spending four years near an ocean or a lake.Those who cannot tolerate heat will probably be more comfortable at a northern college.
School size also plays a major role in the decision process.If you want to get to know your teachers and avoid feeling like just a number,a small college is suitable.For those of you who consider yourself a "people person" and want a wide range of activities,a large college is more fitting.
Your area of interest is another factor to consider in the decision-making process if you want to get the most from your education.The whole point of college is to learn what is of interest to you.
Finally,one must take into consideration the colleges to which you can realistically be accepted.An Ivy League school for an average student would probably not be a good match.Similarly,an average school for an above-average student would not work well.The college should provide enough of a challenge for the student to work hard. Although there may not be the perfect college out there,there probably will be one that is close.Those who cannot find a suitable college are probably not looking hard enough.

Distance from home may also come into consideration. If family is a top priority, that person should stay close to home; on the other hand, if independence is desired, a campus farther from home would be more appropriate.
School size also plays a major role in the decision process. If you want to get to know your teachers, a small college is suitable. For those of you who consider yourself a “ people person” and want a wide range of activities, a large college is more fitting. Your area of interest is another factor to consider in the decision-making process if you want to get the most from your education. The whole point of college is to learn what is of interest to you.
Crucially(至关重要地), one must take into consideration the colleges by which you can realistically be accepted. An Ivy League school for an average student would probably not be a good match.

Many kids start humming tunes like “Twinkle, Twinkle Little Star” as their first songs, but Nygel Witherspoon was an exception. He preferred Finnish composer Jean Sibelius’s Violin Concerto in D Minor.
So when Nygel Witherspoon began to hum the very difficult concerto(协奏曲), his family guessed that he should have music lessons. He was, however, just 3 years old.
“He was calm, with an ability to focus.” recalled David Holmes, Witherspoon’s cello(大提琴) teacher from age 3 to l6.
Witherspoon is a familiar name in his hometown. He has inherited his talent from both sides of his family, including his aunt, the late jazz vocalist Shirley Witherspoon.
The 17-year-old doesn’t see himself as competitive. “I think it’s more important for students to have a supportive environment than a competitive one;” he said. “It’s great to have a support system, where you can be yourself and improve right along with others doing the same thing.”
Witherspoon’s love of music blossomed as he attended viola(中提琴) lessons with older siblings. Their teacher, David France, noticed that the little boy was a sponge(海绵).
“He’d absorb everything they did.” France said. Witherspoon was given a box violin, but he wanted to play “the big one”— the cello. He loved its size and tone. That’s when he was matched with his teacher Holmes.
Witherspoon’s drive is inspired by the connection music provides. He recalled that he and his siblings performed as a chambertrio(室内乐三重奏) at their grandmother’s nursing home. The positive reaction from residents gave him motivation.
“It’s so important, whether it’s hip-hop or classical,” he said. “Music is the universal language. It connects all of us.”
1.How was Witherspoon different from other kids when he was 3?
A.He began to teach himself music.
B.He was able to hum very difficult tunes
C.He had already made up his mind to learn violin
D.He could already play the songs he’d heard.
2.What does Witherspoon think is important for music learners?
A.Practicing hard.
B.Being very competitive.
C.Being in a supportive environment.
D.Having a good teacher from an early age.
3.What is France’s impression of Witherspoon?
A.He is a fast learner. B.He is a creative player.
C.He works very hard. D.He is open-minded.
4.What is the main purpose of the last two Paragraphs?
A.To compare Witherspoon’s performance with his siblings.
B.To show that motivation plays a big role in music studies.
C.To stress that music connects people.
D.To show how studying music helped Witherspoon overcome difficulties.

Many children would start school hungry without breakfast clubs, teachers have claimed. A new survey suggests these clubs are the only way many students can get a meal before lessons.
About 54% of the 552 school staff questioned by the Association of Teachers and Lecturers(ATL)said their school provides a breakfast club for pupils. The biggest reason for them to attend these clubs is that their parents or carer goes to work early, cited by 76.8% of those questioned.
About 22.6% said children attended due to lack of money at home because parents or carers are unemployed and 15.2% said lack of money at home due to changes or cuts to benefits.
About 17.6% said pupils mainly attend breakfast clubs to socialize.
The survey found that teachers believe that offering breakfast to pupils often helps improve their concentration and ability to learn. One primary school teacher said: “Although there is a charge for our breakfast club, we have accessed funding for those pupils on free school meals and the breakfast club had an effect on their attendance, concentration and being in school for the start of lessons.
ATL general secretary Dr Roper said a nutritious meal at the start of the day has a huge impact on pupils’ ability to learn. “Many schools do everything they can to ensure children eat well during school term-time. But there are many children living in poverty, who we fear won’t be getting a decent meal a day in the holidays and this is something the government needs to address,” she said.
A Department for Education spokesman said: “We know how important it is for children to
have a good breakfast. We want schools and local authorities to use their budgets to best meet the needs of their children. Many provide breakfast clubs which offer a free meal to children from poorer families. The Pupil Premium, which will double to £ 2.5 billion in 2014-2015, targets extra money to help schools to provide support such as this to the most disadvantaged children. The free school meal scheme also ensures that these children have access to a nutritious lunch every day.
1.How many factors are mentioned which can account for the popularity of breakfast clubs?
A. Two. B. Three. C. Four. D. Five.
2.By getting breakfast offered by breakfast clubs, pupils can______.
A. perform better in their study
B. know how they can save money
C. eat better for their lunch and supper
D. make more friends with their classmates
3.The pupil Premium and the free school meal scheme are mentioned in order to show_____.
A. every child should get access to a nutritious meal
B. breakfast clubs play a key role in children’s growth
C. many efforts are made to provide a good and free meal
D. many schools can’t offer a good and free meal to children
4.In which part of a magazine can we probably read this passage?
A. Entertainment. B. Education. C. Culture. D. Health.

Many people don't consider their breakfast without a glass of milk. Right now, cows, buffalos, goats and sheep provide most of the world's milk. But soon, people could get milk from roaches(蟑螂).
That isn't as crazy as it might sound. New research shows this "milk" is super﹣nutritious. What's more, some scientists have already begun referring to a lot of insects as source of milk.
In 2004, Subramanian Ramaswamy started studying milk crystals found inside the roach. At the time, he was teaching biochemistry at the University of Iowa City.
To learn more about the milk crystal from roaches, the scientists used X﹣rays to look at the atoms in it. The data basically revealed the chemical recipe of the roach crystal. They showed that roach milk is a "complete food". It contains sugar with a fatty acid stuck to it. Fatty acids are the building blocks of fats. The protein in the milk is also full of essential amino(氨基的) acids, which are the building blocks of proteins. Since our bodies can't produce the "essential" ones, we need to get them from our food. And so do baby roaches.
Barbara Stay, a biologist at Iowa University, also worked on the new study. She says the new data show that the roach milk is "three times more nutritious than cow's milk and four times more nutritious than buffalo's milk".
Ramaswamy would like to see roach milk turned into a protein supplement to feed hungry people. But not everyone is confident that it can be done.
Marcel Dicke studies insects as a potential source of human food at Wageningen University in the Netherlands. Dicke says this is a "sound study". However, in his opinion, "Extracting(提取) milk from roaches can only likely be done in a destructive way with only small quantities". That means you'd have to raise and kill many bugs to get even tiny quantities of the milk.
1.What is the opinion of the scientists about milk in Paragraph 2?
A. Many insects are sources of milk.
B. Milk is an important part of breakfast.
C. Milk from insects is the most nutritious.
D. Milk from insects is well accepted now.
2.What can we know about the use of roach milk in life?
A. It will replace the milk from animals like cows.
B. Scientists think it the key to solving world hunger.
C. All people don't think it can be used in life soon.
D. Most people depend on roach milk from protein.
3.According to Marcel Dicke, extracting insect milk on a large scale is .
A. simple
B. challenging
C. safe
D. necessary
4.What should be the best title for the text?
A. Roach milk has been found scientifically
B. Roach milk could be produced industrially
C. Roach milk could be a new super food
D. Roach milk will be widely used soon
