Directions:Read the following passage.Fill in the numbered blanks by using the information from the passage.

  Write NO MORE THAN THREE WORDS for each answer.

  What is a correct way to take medicine? Reading the question you might think it ridiculous.Actually, how to take medicine means a lot.Knowing it will not only help you preserve the full benefit of your valuable medicine, but also save yourself from potential side effects.For many reasons, no prescription or over-the-counter(非处方的)drug is 100 percent effective in all people or situations.To preserve the full benefit of your medicine, experts say to follow these key steps:

  Ask doctors for help.Discuss drug effectiveness with a doctor before getting a prescription.The doctor can help you explain effectiveness data in product instructions.You can also consult a chemist when buying over-the-counter medications.

  Store drugs properly.For instance, never store aspirin in the bathroom or the refrigerator.That^s because aspirin, like other drugs, can lose effectiveness in damp conditions.Most prescription drugs today come with special storage instructions.Also, some drugs, such as the antibiotic tetracycline, become ineffective when they are exposed to sunlight.

  Do you know how long you should use a certain medicine? Our human body is very smart.It doesn't like any foreign chemical.That's why the body builds up tolerance to many drugs, such as some sleeping pills, and pain medications.If a drug that once was effective no longer seems to help you, consult a doctor before you want to increase the amount of it.

  Cutting a sustained-release(药效持久的)pill can make a drug ineffective or even dangerous.That's because too large a dose of a medicine will be distributed quickly.Also avoid emptying capsules into drinks, say coca cola, milk, juice or food like porridge and soup.So take the pill in a correct way.

  Do you know when to use medicine? You are advised to use medicine at the right time of the day.The instruction of the medicine Renova recommends applying the product at night.The active drug can be destroyed by sunlight.Also, applying two medicines to your skin at the same time might make them both ineffective.Taking drugs at recommended times, such as before meals, can increase absorption.

  Some people may store medicine they bought years ago.In actual fact, over time, many drugs experience chemical changes.So pay attention to expiration(截止)dates listed on labels or ask your chemist a drug ^ s shelf life.Don ^ t hesitate to throw old pills if possible.

  As you can see, taking medicine correctly is very important for many reasons, so make sure you follow these tips.

   阅读下列短文,从每题所给的A、B、C和D项中,选出最佳选项,并在答题卡上将该项涂黑。
A
Do you have any idea what you would like to be and do after graduation? A lot of people don't begin thinking about career until they reach junior or senior year, which, in my opinion, is too late.
When people are trying to decide what they want to do, it helps to know something they love. Ever since I was little, I’ve always been doing someone’s hair, make-up or nails, starting with Barbie dolls and progressing to humans. Over the years my family has really inspired me to do this and now I fix friends’ and family members’ hair for weddings, dances and other big events.
I have been thinking about what I would like to do for a career since middle school. I did some research and discovered that I might really enjoy being a cosmetologist so, I went to my hair stylist and asked her lots of questions about what it takes to reach her level and what she would recommend I do. I considered her advice and then did more research.
I used Aveda’s website to get information on the Aveda Institute and what type of credits(贷款) I would need from high school to apply. I found their institute has three parts: theatrical knowledge, practical experience, and professional business-building skills. For the past few years, I have been looking at Aveda in more and more detail. This school not only offers cosmetology, but also massage therapy(疗法). I grew up in Minnesota(美国北部的一个州), so I plan to apply to the institute in Minneapolis that several people have highly recommended. It helps students become “future industry leaders in hair care, skin care, makeup and total body wellness”. It is affordable and everyone there is friendly and understanding.
Having done the groundwork and thinking about what I’d like to do after high school, I know that I will definitely pursue my dream of becoming a cosmetologist.

Ellen Swallow Richards was the first woman to earn a bachelor’s degree from Massachusetts Institute of Technology (MIT). A chemist, social activist, teacher, and first woman member of the Institute of Engineering, she believed that housekeeping was a science. As a progressive thinker at the time, she thought that women needed to learn about money matters and have up-to-date information on cleanliness and nutrition. She encouraged women from all backgrounds to get the best education possible.
Ellen was born in 1842 and was brought up in Massachusetts. A graduate of Vassar College in New York, she returned to New England to attend MIT. After her marriage to Professor Robert Richards, she worked in a laboratory at MIT, examining pollution of water sources in Massachusetts. Her work led to the creation of the first food-inspection (检验) laws of that state. She was instructor at MIT from 1884 until her death in 1911.
Like other progressive thinkers of the time, Ellen was worried about problems of the poor and the effect of the environment on society. She considered the environment a key factor in quality of life. Within the family, as in the world at large, science was chief in tools used to help the poor. Science could help to manage money matters, keep a home safe and clean, and improve quality of life. Food properly cooked could be tasty, nutritious, and inexpensive. Better and cheaper food could protect the health and improve the lives of working-class families.
Ellen created the science of housekeeping, now called home economics, and elevated(提升)it to a serious college subject. She worked tirelessly as a national leader in developing standards, materials, and teacher training for this new field. Her publications cover many subjects—from the chemistry of cooking and cleaning to the cost of living.
57. According to the text, Ellen __________.
A. provided new jobs for the poor            B. helped to create new kinds of food
C. set up the field of home economics         D. created the ideas of food-inspection laws
58. As a progressive thinker, Ellen __________.
A. suggested people cook their own meals at home
B. believed cheap food was better than expensive one
C. advised women to get the best education possible
D. considered money matters a key factor in quality of life
59. Ellen believed that __________.
A. poor families knew how to manage money
B. families were well informed about good nutrition
C. cheaper food could not protect people’s health
D. families spent much on food but were not well nourished
60. One can infer that, as a result of the efforts of people such as Ellen, __________.
A. one may study home economics at a university for a career
B. the pollution of water sources is no longer a problem
C. most people today learn to cook at school
D. science does not help much within the family as in the world

What do you want to be when you grow up? A teacher? A doctor? How about an ice-cream taster?
Yes, there really is a job where you can get paid to taste ice-cream. Just ask John Harrison, an “Official Taste Tester” for the past 21 years. Testing helps manufacturers to be sure of a product’s quality. During his career Harrison has been responsible for approving large quantities of the sweet ice cream — as well as for developing over 75 flavors (味道).
Some people think that it would be easy to do this job: after all, you just have to like ice cream, right? No — there’s more to the job than that, says Harrison, who has a degree in chemistry. He points out that a dairy or food-science degree would be very useful to someone wanting a career in this “cool” field.
In a typical morning on the job, Harrison tastes and assesses 60 ice-cream samples. He lets the ice cream warm up to about 12℉. Harrison explains, “You get more flavor from warmer ice cream, which is why some kids like to stir it, creating ice-cream soup.”
While the ice cream warms up, Harrison looks over the samples and grades each one on its appearance. “Tasting begins with the eyes,” he explains. He checks to see if the ice cream is attractive and asks himself, “Does the product have the color expected from that flavor?” Next it’s time to taste!
Continuing to think up new ideas, try out new flavors, and test samples from so many kinds of ice cream each day keeps Harrison busy but happy — working at one cool job.
【小题1】What is John Harrison’s job?

A.An official.B.An ice-cream taster.
C.A chemist.D.An ice-cream manufacturer.
【小题2】According to John Harrison, to be qualified in the “cool field”, it is helpful to ______.
A.keep a diary of work B.have a degree in chemistry
C.have new ideas every dayD.find out new flavors each day
【小题3】What does Harrison do first when testing ice cream?
A.He stirs the ice cream.
B.He examines the color of the ice cream.
C.He tastes the flavor of the ice cream.
D.He lets the ice cream cool down.
