My mother asked me to go to several garage sales  (宅前旧货出售) with her one cool morning.

We finally__26__at a pleasant house in the woods.The elderly__27__told me that he and his wife were retired (退休的) teachers.As we were searching，I heard the gentleman’s wife say her__28__to someone，and I immediately__29__who she was.She looked at me and said，“You’re Lisa Miller.” I looked at her__30__，for it had been nearly thirty__31__since I had been in her class.

My mother immediately said sorry to her for any__32__I might have made.She did that again after learning that I wasn’t the sweet little child.She thought that if this woman__33__me after so many years，I must have done something__34__.My teacher looked at my mother and__35__said，“Oh，no，she was very good.”

My teacher__36__that during the last week of school，I__37__her a plant from my mother’s garden.It was a lamb’s  ear.She took us to her garden where she planted the lamb’s ear.Over the years it__38__.As I looked down her driveway  (车道) with lamb’s ears on both sides，she said，“Every day when I leave my house and drive up the driveway，I think of you.And when I come home they__39__me，I think of you.”  Tears__40__my eyes.There at her home was a piece of my  life that she had raised.

At that moment，she taught me more about__41__than I  could imagine.We give pieces of ourselves every day__42__thought.We seldom imagine the effects (影响) that we have  on others’ lives.That piece may grow and spread，becoming  a(n)__43__part of a life.In the end it isn’t the big things that  matter，__44__the small things that make all the__45__in the  world.

A super drug that could remove Alzheimer’s (老年痴呆症)，heart disease and diabetes (糖尿病) and help people live to 100 is being developed by scientists. Their research is based on the identification of three genes that help prolong lives and prevent diseases which occur in old age. Medically controlling the proteins made by the “ longevity genes” will allow millions to live longer, predicts Dr Nir Barzilai.

  Those whose DNA strongly features the three genes are 80 percent less likely to develop Alzheimer’s. The genes also fight against the deadly impact of smoking, poor diet, obesity and lack of exercise.

  Already, several laboratories are working on a pill to imitate the benefits of the genes and Dr Barzilai thinks it could be tested within three years. The pill could remove some diseases that damage old age. “ The advantage of finding a gene that involves longevity is that we can develop a drug that will imitate exactly what this gene is doing,” he said.

  Of the three longevity genes, two genes increase the production of so-called good cholesterol(胆固醇), which reduces the risk of heart disease. The third prevents diabetes. They were discovered by Dr Barzilai’s team while studying the DNA of 500 Ashkenazi Jews with an average age of 100. The chances of living that long are one in 10,000 but the group, which shared relatively few common ancestors, was 20 times more likely to hit the entury. Dr Barzilai said: “ 30 percent of them were obese or overweight and 30 percent smoked two acks of cigarettes a day for more than 40 years, however they can live to 100.”

  But Andrew Ketteringham of the Alzheimer’s Society said: “Alzheimer’s disease, a most common disease, is likely to be caused by a combination of genetic disosition(遗传倾向), lifestyles and life events. Many genes are probably involved.

Some people are able to live to 100 years because of ______.

   A. a magical medicine  B. three special genes    C. good living habits     D. longevity proteins

Why does the discovery of the longevity genes mean a lot?

   A. Because it can bring great benefits to scientific labs.              

B. Because it can help people change their unhealthy genes

   C. Because it helps produce a drug that can make people live longer.  

D. Because it will help scientists build up a new branch of biology.

From Paragraph 4 we can infer that ________.

   A. longevity genes can create good cholesterol.                   

B. the volunteers share some common ancestors

   C. bad habits are likely to have no effect on the volunteers           

D. longevity genes protect the volunteers against bad habits

What is Andrew Ketteringham’s attitude toward the study?

   A. Positive    B. Negative         C. Critical                 D. Cautious
