Alzheimer’s disease is a major national health problem. Nearly 2 million Americans over the age of 65 have Alzheimer’s disease. It is a leading cause of death among the elderly. But Alzheimer’s disease is not confined （限于） to the aged. There may be a million or more people under the age of 65 suffering from the disease.

　　At one time, people suffering from the disease were said to be“getting old”.The disease was thought to be a natural part of growing old, but it is now known that Alzheimer’s disease strikes young and old alike. It is an organic disease which destroys brain cells.

　　Alzheimer’s disease affects the patient’s memory, speech, and movement. In the beginning stages of the disease, the patient may seem slightly confused. He may have trouble speaking, then the patient’s memory begins to fail. He may forget dates, numbers, names and plans.

As the disease progresses, the patient may not recognize family and friends. These symptoms（症状） often cause terrible anxiety in the patient. He may feel lost and frightened. Sometimes the patient reacts with wild and bad behavior.

　　In the last stages of the disease, the patient may not be able to take care of himself. He may have lost the ability to speak and walk.

　　Scientists don’t know exactly what causes Alzheimer’s disease. It may be caused by a virus.It may be caused by a poisonous substance（物质） in the environment. At present, there is no cure for the disease. But there are ways to slow its progress. Exercise and physical treatment can help the patients of this disease.

Everyone needs friends. There is an old saying, “Friends are God’s way of taking care of us.” But how do you find real friendship and keep it?
The American writer Sally Seamans tells young students some smart ways to find friends. Sally says finding friendship is just like planting a tree. You plant the seed(种子) and take care of it to make it grow.
First, you should choose a friend. What makes a good friend? It is not because a person has money or good looks. A good friend should be kind and patient(耐心). For example, if you have a bad day, a good friend should listen to your complaints and do his best to help. To make a good friend, you cannot be too shy. You should make each other happy and share your lives.
But things cannot always be happy. Even the best friends have fights. What should you do when you have a fight with your friend? You have to talk to him or her. When there is no one around, have an honest talk. If he or she doesn’t want to talk, you could write a letter.
There are three steps to being friends again:
Tell him or her how you are feeling; say what your friend has done wrong, and explain why you did this or that. Remember that friendship is the most important thing in your life.

Discouraged by reading bad news daily and with his marriage failing, Canadian Neil Pasricha  decided to try to focus on the positive and come up with 1,000 simple, free, awesome things, posting one each day on a blog.

       Pasricha said his blog aimed to highlight life's simple pleasures, which were often taken for granted, such as finding forgotten money in a pocket, or fixing a TV set with a heavy blow.

       Little did he realize his blog would strike a nerve and attract 40,000 people a day to join his discussions on how to enjoy the last triangle of a potato crisp, or the pleasure of laughing so hard that you cry.

       Pasricha, aged 30, was amazed to win two Webby awards, known as "the Oscars of the Internet," something positive at a time when his marriage broke up and one of his closest friends committed suicide.

       "I turned the worst year of my life into my best year by focusing on the positive. " Pasricha told Reuters in a telephone interview. "Every day I try to find something that is happy, free and universal to share, like the smell of a bakery or when a cashier opens up a new line at a store. "

       Pasricha said when he began his blog in June 2008 he thought he might have trouble coming up with 1,000 simple, happy moments in life but now he is more than halfway through and ideas keep flooding in, from himself and from followers of his blog.

       "These moments can start a huge conversation. Most of our life is really about hitting green lights on the way home from, or waking up before your alarm goes off and realizing you have more time in bed. But it is those small moments we forget about."

       Despite the success of his blog, Pasricha does not want to change his daily life. “I travel regularly for an hour a day to work in the suburb. I like work because I like the people in my office. I’m not a writer and I don’t know how to use punctuations correctly. I just like observing the world and putting it down,” he said.

Neil Pasricha determined to post positive feelings or things on his blog because          .

       A．daily bad news and broken marriage saddened him

       B．1,000 simple, free, happy things excited him

       C．he wanted to forget his marriage life

       D．he wanted to make his blog successful

Which of the following will Pasricha probably NOT post onto his blog?

       A．Coming across an old schoolmate.

       B．Finding his lost dog come back home.

       C．Falling off his bike and getting injured.

       D．Buying his favourite book at a special price.

According to the passage, Pasricha         .

       A．gets ideas for 1,000 simple, free, happy things with trouble

       B．gets ideas for 1,000 simple, free, happy things on his own

       C．is on his way to collecting 1,000 simple, free, happy things

       D．has finished collecting 1,000 simple, free, happy things

Which of the following might be the best title for the poassage?

       A．Hard life for a Canadian blogger    B．Busy life for a Canadian blogger

       C．Great awards for a Canadian blogger     D．Great success for a Canadian blogger

Five Simple Ways to Increase Your Intelligence

Your brain needs exercise just like a muscle. If you use it often and in the right ways, you will become a more skilled thinker and increase your ability to focus.  

Here are 5 simple ways anyone can squeeze a bit more productivity out of the old gray matter.

1. __________-This is a hard sell. People love vegetating in front of the television, myself included more often than I’d like. The problem is watching television doesn’t use your mental capacity OR allow it to recharge. It’s like having the energy sapped out of a muscle without the health benefits of exercise.

When you feel like relaxing, try reading a book instead. If you’re too tired, listen to some music. When you’re with your friends or family, leave the tube off and have a conversation. All of these things use your mind more than television and allow you to relax.

Exercise- I used to think that I'd learn more by not exercising and using the time to read a book instead. But I realized that time spent exercising always leads to greater learning because it improves productivity during the time afterwards. Using your body clears your head and creates a wave of energy. Afterwards, you feel invigorated（精力充沛）and can concentrate more easily.

2. __________-Many people like to read popular suspense fiction, but generally these books aren't mentally stimulating. If you want to improve your thinking and writing ability you should read books that make you focus. Reading a classic novel can change your view of the world and will make you think in more precise, elegant English. Don’t be afraid to look up a word if you don’t know it, and don’t be afraid of dense passages. Take your time, re-read when necessary, and you’ll soon grow accustomed to the author’s style.

3. __________-Nothing makes it harder to concentrate than sleep deprivation. You'll be most rejuvenated if you go to bed early and don’t sleep more than 8 hours. If you stay up late and compensate by sleeping late, you’ll wake up lethargic（无精打采）and have trouble focusing. In my experience the early morning hours are the most tranquil and productive. Waking up early gives you more productive hours and maximizes your mental acuity（敏锐）all day.

If you have the opportunity, take 10-20 minute naps when you are hit with a wave of drowsiness. Anything longer will make you lethargic, but a short nap will refresh you.

4. __________-Often our lives get so hectic that we become overwhelmed without even realizing it. It becomes difficult to concentrate because nagging thoughts keep interrupting. Spending some time alone in reflection gives you a chance to organize your thoughts and prioritize your responsibilities. Afterwards, you’ll have a better understanding of what's important and what isn’t. The unimportant stuff won’t bother you anymore and your mind will feel less encumbered.

Conclusion-I hope you aren’t disappointed that none of the techniques I've proposed are revolutionary. But simple, unexciting answers are often the most valid. The challenge is having the will to adhere to them. If you succeed in following these 5 tips, you’ll be rewarded with increased mental acuity and retention of knowledge.

When you first meet a disabled person, what is your first reaction? Curiosity? Sympathy? If you experience any of these emotions, you are not alone．Chances are that you don’t regularly associate with someone who is disabled．Here are four points to keep in mind if you should happen to meet a disabled person.
Disabled people can lead active lives
With few exceptions, a disability does not prevent someone from working, raising a family, or taking part in social activities．Many sports and recreation programs have been adapted to a person with a disability．Instead of concentrating on the disability, look at the person the same way you would any normal person.
It’s all right to ask questions
Many people are afraid of offending someone by asking about their disability．When meeting them for the first time, it’s natural to be curious about who he or she is, and where they’re from．Asking questions is usually acceptable, as long as you use common sense．Don’t, for example, ask a blind person how he feeds and bathes himself.
Offer help when necessary
You see a woman in a wheelchair having trouble entering a building．It’s usually appropriate to lend a hand if someone is having obvious difficulty, but keep in mind that not everyone will be willing to accept your help．Unless the woman in the wheelchair is in danger, you do your part.
Remember that we all have obstacles to overcome
No matter who we are, each of us has a weakness or challenge to face．Like you, a disabled person would much rather be accepted for who they are, rather than be pitied．Many friends have said to me, “I often forget that you are blind.” To me, that is the top compliment(赞扬).
1．Why are you curious when you first see disabled people?
A．They can’t live normally．           B．You seldom deal with them.
C．You look down upon them．         D．They look quite different.
2．What should you do if you find a disabled person can manage it?
A．You had better lend him or her a hand.
B．You pretend that you haven’t seen him or her.
C．You should encourage him or her to try.
D．You had better let him or her alone.
3．From this passage we learn that ____.
A．the author is blind himself
B．a disabled person needs pitying
C．not everyone has a weakness
D．some people have no difficulty
