You may know your mother, but how well do you really know Mother’s Day? Cards, flowers, sales, TV specials, and a day off for someone who really deserves it ---- those are what probably come to mind for many people when they think of Mother’s Day. But there’s more to the story.
The earliest Mother’s Day celebrations were held during spring in ancient Greece. The celebrations honored Rhea, the Mother of the gods. During the 1600’s, England celebrated a day called Mothering Sunday. On this day even servants were given the day off to spend with their families. A mothering cake was even served with the family meal.
In the US, Mother’s Day began in 1872 when Julia Ward Howe, who wrote the words to the famous song The Battle Hymn of the Republic, suggested it as a day devoted to peace. But it didn’t really become popular until 1907 when Anna Jarvis stared a campaign to honor mothers. She believed that mothers could help people get over the pain they experienced during the Civil
War. The US isn’t alone in devoting a day to mothers. Many other countries including Denmark, Finland, Italy, Turkey, Australia, Japan, and Belgium also honor their mothers in May. Other countries honor their mothers at different times of the year.
Learning more about Mother’s Day and celebrating Mother’s Day are important, but probably not as important as understanding what your own mother, or grandmother, or aunt has really done for you. And that will certainly be appreciated more than one day in a year.
【小题1】What is the passage mainly about?

   The term “multitasking” originally referred to a computer’s ability to carry out several tasks at one time. For many people, multitasking has become a way of life and even a key to success. In fact, some excellent mental aerobic exercises (大脑训练) involve engaging the brain in two or more challenging activities at a time. Although checking e-mail while talking on a phone and reading the newspaper may be second nature for some people, many times multitasking can make us less productive, rather than more. And studies show that too much multitasking can lead to increased stress, anxiety and memory loss.

   In order to multitask, the brain uses an area known as the prefrontal cortex (前额叶脑皮层). Brian scans of volunteers performing multiple tasks together show that as they shift from task to task, this front part of the brain actually takes a moment of rest between tasks. You may have experienced a prefrontal cortex “moment of rest” yourself if you’ve ever dialed (拨电话) a phone number and suddenly forgotten who you dialed when the line is answered. What probably occurred is that between the dialing and the answering, your mind shifted to anther thought or task, and then took that “moment” to come back. Research has also shown that for many volunteers, job efficiency (效率) declines while multitasking, as compared to when they perform only one task at a time.

   Multitasking is easiest when at least one of the tasks is habitual, or requires little thought. Most people don’t find it difficult to eat and read the newspaper at the same time. However, when two or more attention-requiring tasks are attempted at one time, people sometimes make mistakes.

   We often don’t remember things as well when we’re trying to manage several details at the same time. Without mental focus, we may not pay enough attention to new information coming in, so it never makes it into our memory stores. That is one of the main reasons we forget people’s names---even sometimes right after they have introduced themselves. Multitasking can also affect our relationships. If someone checks their e-mail while on the phone with a friend, they may come off as absent-minded or disinterested. It can also cause that person to miss or overlook key information being passed on to them.

1.Why are some mental aerobic exercises designed to engage people in multitasking?

    A. To make them more productive.         B. To reduce their stress and anxiety.

C. To develop their communication skills.  D. To help them perform daily tasks more easily.

 A. He may leave his prefrontal cortex temporarily damaged.

 D. He may need a rest between dialing and speaking.

3.People tend to make mistake when ____.

   A. they perform several challenging tasks at a time.

   B. new messages are processed one after another

   C. their relationships with others are affected

   D. the tasks require little thought

A. Multitasking has become a way of life.

B. Multitasking often leads to efficiency decline.

C. Multitasking exercises need to be improved.

D. Multitasking enables people to remember things better.

No one knows for sure when advertising first started.It is possible that it grew out of the discovery that some people did certain kinds of work better than others did them.That led to the concept of specialization，which means that people would specialize，or focus，on doing one specific job.

Let’s take a man we’ll call Mr.Fielder，for example.He did everything connected with farming.He planted seeds，tended the fields，and harvested and sold his crops.At the same time，he did many other jobs on the farm.However，he didn’t make the bricks for his house，cut his trees into boards，make the plows(犁), or any of the other hundreds of things a farm needs.Instead，he got them from people who specialized in doing each of those things.

Suppose there was another man we shall call Mr.Plowright.Using what he knew about farming and working with iron，Mr.Plowright invented a plow that made farming easier.Mr.Plowright did not really like farming himself and wanted to specialize in making really good plows.Perhaps，he thought，other farmers will trade what they grow for one of my plows.

How did Mr.Plowright let people know what he was doing？Why，he advertised，of course.First he opened a shop and then he put up a sign outside the shop to attract customers.That sign may have been no more than a plow carved into a piece of wood and a simple arrow pointing to the shop door.It was probably all the information people needed to find Mr.Plowright and his really good plows.

Many historians believe that the first outdoor signs were used about five thousand years ago.Even before most people could read，they understood such signs.Shopkeepers would carve into stone，clay，or wood symbols for the products they had for sale.

A medium，in advertising talk，is the way you communicate your message.You might say that the first medium used in advertising was signs with symbols.The second medium was audio，or sound，although that term is not used exactly in the way we use it today.Originally，just the human voice and maybe some kind of simple instrument，such as a bell，were used to get people’s attention.

A crier，in the historical sense，is not someone who weeps easily.It is someone，probably a man，with a voice loud enough to be heard over the other noises of a city.In ancient Egypt，shopkeepers might hire such a person to spread the news about their products.Often this earliest form of advertising involved a newly arrived ship loaded with goods.Perhaps the crier described the goods，explained where they came from，and praised their quality.His job was，in other words，not too different from a TV or radio commercial in today’s world.

A．the history of advertising

The Book of Life
So far, scientists have named about 1.8 million living species(物种), and that’s just a small number of what probably exists on Earth. With so many plants, animals, and other living things coveting the planet, it can be tough to figure out what type of grass is growing by the roadside or what kind of bird just flew by.
A soon-to-be-started Web site might help. An international team of researchers has announced the creation of Web-based Encyclopedia(百科全书) of Life ( EoL). The project aims to list every species on Earth in a single, easy-to-use reference guide.
To get the encyclopedia started, the creators will use information from scientific databases (数据库) that already exist. And eventually, in special sections of the site, non-scientists with specialized knowledge will come to help. Bird-watchers, for example, will be able to input what birds they’ve seen and where. To make sure the encyclopedia is accurate, scientists will review much of the information added to it.
As the EoL develops, you might find it useful for school projects. The site will feature (以……为特色) special pages for kids who are studying ecosystems in their neighborhoods. Another convenient feature of the EoL is that you’ll be able to pick the level of detail you want to see to match your interests, age, and knowledge.
It now takes years for scientists to collect all the data they need to describe and analyze species. The creators of the Encyclopedia of Life hope that their new tool will speed up that process.
