Do you want to keep your brain active and your memory strong? Here are some useful ways:

Choose the Brain Food

A proper diet will help keep your mind running strong all day long. Make sure to include plenty of fruits and green vegetables. Some of the best foods include: blueberries, blackberries, fish and fish oil, eggs, strawberries and so on.

Exercise

Get your body moving and your memory will soon follow. Exercise improves the heart’s blood flow. This, in turn, helps the brain function better and stay sharper.

Pick up a Book

The key to keeping your memory quick is to continue to challenge it. Try to always have a book in hand. After you’ve done reading a section or two, question and review the material you’ve read. Try to imagine what you’re reading. Discuss what you’ve read, and talk about it with friends or join a book club.

Develop Interest

We remember new things because we enjoy them. Find ways to make a boring subject fun by connecting it to something you already know. You can use your imagination and create a fun story behind a subject to help make it easier to remember.

Repeat after Me

When learning new information, the more you repeat it, the more likely you will be able to remember that information. Practice is the key to lasting memory.

Share with Others

Don’t keep your knowledge stored up. Teaching others is another great way to improve memory skills. Don’t be afraid of taking on new challenges. After learning something, it’s necessary to put the new information to use.

What is a spelling bee?    1  , but it is so popular in the Unite States. It is a game for children to spell English words.

       The National Spelling Bee is the largest education contest(比賽) . It first began in 1925 in Washington.D. C.   2 . It is open to students in eighth grade or lower and not reaching their 15^th birthday.

       The contest is quite simple. When it's your turn, the teacher says a word and you have to spell it.   3  , you stay in the game. If you spell it wrong, you're out. What's not so easy are the words the teachers ask you to spell.

       Usually, children need to spend a lot of time learning vocabulary. They must remember thousands of English words and spell every word correctly in the contest. Only winners in regional (地區(qū)的) contest can enter the national contest. It’s many children’s dream to win the regional contest and go to Washington, D. C. The final winners will be called the Spelling Bee.  4 . Do you also think they are great?

It is easy for us to tell who our family members are, but do plants recognize(識別) their own family? Some do, scientists say, according to a report by Science News in early 2010.

Guillermo P. Murphy and Susan Dudley are two plant scientists from McMaster University in Hamilton, Canada. They did a few experiments with Jewelweeds, a kind of flower that grows in wet, shady spots. They found that the flowers seem to know their own flower family. In their experiments, Murphy and Dudley planted jewelweeds in pots with either siblings or strangers.

When jewelweeds were planted in pots with strangers, the plants started to grow more leaves than if they had been planted alone. This response(反應)suggests that plants are competing with strangers for sunlight, since a plant with more leaves can receive more light and make more food. Jewelweeds usually grow in the shade, where sunlight is not enough.

When jewelweed seedlings(幼苗)were planted with siblings, they grew a few more branches than they usually would if they were alone – but they did not start growing lots of extra leaves. This behavior suggests the plants are more likely to share resources, rather than compete.

According to the Science News report, Jewelweeds are not the first plants that plant scientists have studied for family recognition. In 2007, Dudley and her team studied the Great Lakes sea rocket, a plant that grows on the beach – where it may be hard to get fresh water. In that experiment, the scientists found that when sea rockets were planted with siblings, they tolerated each other. But when they were planted with strangers, the sea rockets reacted by working extra hard to grow lots of roots. 

Dudley says this just because sea rockets, on the beach, get plenty of sun but struggle for water – so when they’re threatened, they compete for water. Jewelweeds have plenty of water but have to compete for sunshine, so they grow more leaves.

1What does the underlined word siblings mean?

A. Flowers come from foreign countries.

B. Plants growing in different environments.

C. Flowers planted with lots of strangers.

D. Plants that are the same kind.

2 In the text, the writer mentioned the experiments of Jewelweeds to         .

 A. make a comparison                       B. introduce a topic

C. describe a pretty flower           D. build a new theory

3According to the passage, flowers planted alone will         .

A. grow more leaves than those planted in groups

B. become taller than those with more branches

C. grow fewer leaves than those planted with strangers

D. become ill easily because they can’t get enough shade

4What can be the best title for the passage?

A. New Discoveries about Plants        

B. How Plants Compete with Each Other

C. Family Recognition among Plants    

D. Jewelweeds and the Great Lakes Sea Rockets
