Do you always forget where you placed your keys or your purse? What was the name of the movie you saw last week? The major cause of your forgetfulness may be linked to what you store in your body, not in your short-term memory bank.

Tests continue to show that people with enough Vitamin B-2 do well in memory exams. The "B" could stand for "brain", if you're one of many with limited instant recall. And the number one source of that vitamin (维生素) is sunflower seeds.

Even when you're sleeping or relaxing, your brain is still at work. Although it makes up just two percent of your total body weight, it uses up to 30 % of the calories (卡路里) you take in each day. For it to work properly, it must be fed. Even if you're not a breakfast eater, that meal is the best way to prepare your brain for the day. A quick and easy English muffin with peanut and butter in it, a glass of milk, and an orange, might be what your brain may be asking you the first thing in the morning when you feel your head is in a fog. Having sunflower seeds and fruit between meals adds more muscle to that hungry, demanding organ. Vitamin B-1 also helps the memory, and that is found in eggs, meats and nuts. In Chinese culture, walnuts are known as the fruit for a long life because it is believed that they feed both the kidneys and the brain. And according to Chinese culture, if you keep those two important organs in good working order, you'll live longer.

However forgetful you are, just keep in mind the letter "B", which will help you to "bear in mind almost everything" even on those days when life's challenges are sending you in a billion directions.

1.The underlined word "muffin" in the third paragraph probably means________.

A. menu B. dinner C. cookie D. calorie

2.What can we conclude from the passage?

A. Two percent of our brain is still active when we are sleeping or relaxing.

B. What we eat seems more important than what we learn in terms of memory.

C. It doesn't make much difference to our brain whether we have breakfast or not.

D. Life's challenges have no effect on our memory, if dealt with in a proper way.

3.In the passage, Chinese culture is mentioned to________.

A. support the idea of long life

B. warn the readers of two organs

C. show the importance of vitamin B-1

D. remind us of walnuts and sunflower seeds

4.What can you get from the passage?

A. Keep in mind the letter "B"

B. The younger, the better memory

C. Learn about Chinese culture

D. Try to get more rest

Take a part-time job is a good form of social practice. That we have learned in books and in class can’t have the same important effect us as what we have learned through personal practice. In social practice, we can surely make a progress in both knowledge or practical ability. Beside, when we take a part-time job, we may got paid more or less to help our family.

About five years ago, an American electrical engineer named Scott Brusaw and his wife Julie came up with the idea of putting solar panels (控制板) on the ground rather than the roof. Then they began to develop the Solar Roadway. The Solar Roadway is an intelligent road that provides clean renewable energy using power from the sun while providing safer driving conditions, along with power and data delivery. They predict that the Solar Roadway will pay for itself through the generation of electricity along with other forms of income and that the same money that is being used to build and resurface current roads can be used to build the Solar Roadways.

Each Solar Road Panel measures roughly 4 meters by 4 meters and contains a microprocessor (微处理器) that monitors and controls the panel, while communicating with neighboring panels and the vehicles traveling overhead. The inventors suggest that this provides a communications device every 4 meters on every road which could be used for example to warn drivers of cars which are moving across a centre line and various other speed control problems. The top of the Solar Road panels is made of super-strong glass that would offer vehicles the tractions (抓地力) they need.

According to the inventors, the Solar Roadway creates and carries clean renewable electricity and therefore electric vehicles can be recharged at any conveniently located rest stop, or at any business that has paved Solar Road Panels in their parking lots.

The inventors say their Solar Roadway has many functions and advantages from main roads to driveways, parking lots, bike paths, sidewalks and runways. The Federal Highway Administration has given Brusaw $100,000 to develop the invention and Brusaw hopes to build a smart-road parking lot in the coming spring .

1.In the inventors’ opinion, the Solar Roadway ___________________________ .

A. is too expensive to build at present

B. costs no more money than current roads

C. can provide as many data as present computers

D. will bring them a large sum of money

2.The underlined word “they” in Paragraph 2 refers to .

A. the panels B. the inventors

C. the researchers D. the vehicles

3.It can be inferred from the text that ____________________________.

A. the Solar Roadway has already been put into use

B. $100,000 is only enough to build a smart-road parking lot

C. the Solar Roadway is not available for gas-powered cars

D. future electric vehicles can be charged anytime and anywhere

4.What can be the best title for the text?

A. Solar-powered smart road of the future

B. The great changes on the roadway

C. The influence the Solar Roadway has on people

D. The Solar Road—a much faster road
