I clearly remember my mom telling me to drink milk every day—one glass in the morning and another at night. I also remember loving it while my sister thought quite the opposite—she would surreptitiously pour her milk into the sink or water the plants with it! I guess I should thank my mom for making us drink a lot of milk, so rich in calcium(鈣), during those important years.

Today, calcium shortage is one of the main concerns of women in their 30s or even early 20s. The great fear is that when we reach our 50s or 60s, osteoprosis(骨質(zhì)疏松癥)will set in. That is why you can see a lot of advertisements for products supposedly containing a lot of calcium.

Because calcium is not that easy to acquire from the food we normally eat, busy women these days should take calcium supplements(補(bǔ)充物). There are a lot of different forms of these---calcium carbonate(碳酸鈣)，oyster(牡蠣)shell or bone-meal-based calcium supplements.

You have to be careful when choosing which kind to take. This is because calcium is not easily absorbed by the body. So the fact that you are taking supplements doesn’t mean that the body is actually benefiting from them. Different supplements may have different instructions on dosage(劑量)and manner of intake. You can ask your doctor to help you determine which supplement is the best for your needs.

1.From what the author’s mother did we may infer that___________________.

A．her children had osteoporosis

B．she knew her children would benefit from milk

C．she must have suffered from osteorosis

D．she didn’t like her daughter who didn’t obey her order

2. Based on the passage, which of the following is NOT true?

A．The author’s sister will suffer from osteoprosis when reaches her 50s or 60s

B．Many businessmen have already been selling products supposedly containing calcium.

C．We can’t get enough calcium only from food we eat every day

D．Women as young as their 20s should be concerned about calcium shortage

3.What does the underlined word “surreptitiously” in the first paragraph probably mean?

A．Honestly

B．Frankly

C．Secretly

D．Curiously

4.We may infer from the last paragraph that____________________.

A．what one chooses as a calcium supplement might not work

B．one shouldn’t take in calcium without the permission of a doctor

C．the more calcium supplements one uses, the more calcium one can take in

D．it is dangerous to use calcium supplements without the guidance

Memory， they say， is a matter of practice and exercise. If you have the wish and really make a conscious （有意識的） effort， then you can quite easily improve your ability to remember things. But even if you are successful， there are times when your memory seems to play tricks on you.

     Sometimes you remember things that really did not happen. One morning last week， for example， I got up and found that I had left the front door unlocked all night， yet I clearly remembered locking it carefully the night before.

     Memory “tricks” work the other way as well. Once in a while you remember not doing something and then find out that you did. One day last month， for example， I was sitting in a barbershop（ 理發(fā)店）  waiting for my turn to get a haircut， and suddenly I realized that I had got a haircut two days before at the barbershop across the street from my office.

While I was in 9th grade, I built a circuit (電路裝置) for the traffic system of our city. After getting the first prize, I got this valuable advice from my father: “Do whatever interests you, and don’t let the work challenge you, make sure you are challenging that work.” 

I have always preferred the projects which are challenging and related to real life problems. I clearly remember building a shipping program several years ago. I divided the whole project into several small sections. When I understood it clearly, I used my brainstorming skill on it, and gave some basic ideas. Then I asked my professor for help before jumping into coding (編碼). At first, I did not know how to ask questions correctly and always asked the question “How do I do it?” As I kept working and discussed with my professor, I became more comfortable and those “how” questions soon turned into “what if I do this and that” types of questions.

     It took me four days to write the code. The desire to solve the problem kept me sleepless all nights brainstorming in even greater details. Every time I saw my program running smoothly, I exploded with joy. I still remember the last day of my work. I was getting some problem and didn’t know what to do. At that moment, a man came in to clean. He had headphones, and he was dancing while cleaning the room. Seeing this, I burst out laughing. That moment calmed me. I regained energy and interest and started to work again, and soon I fixed the problem.　

    My success in the project proved that breaking up a large problem into small parts could help find a possible solution. Discussing the problem with others was also very beneficial. Now I have gained the confidence to attempt any kind of project.　

According to the passage, the writer was interested in ______.

  A. developing traffic systems          B. doing challenging projects

C. winning great prizes                 D. writing different codes

The writer asked the question “how do I do it” at first because ______.

A. he had no clear idea about his program   B. he was too shy to express himself

C. he wanted to be understood easily       D. he preferred this kind of question

We learn from the passage that the writer’s shipping program ______.

A. would benefit people a lot             B. was done together with others

C. was difficult and needed patience       D. cost much money and energy

What would be the best title for the passage?

A. Do It Yourself           B. No Pains, No Gains

C. Learning with Interest               D. Practice Makes Perfect

Many college-bound freshmen are worrying about more than just who their roommates will be this fall. They may also be nervous about the well-known fact that they are likely to gain weight this school year. Or will they? While many of us remember the extra weight that showed up right around the start of our college careers, we are not always clear on how much weight we realize gained or why.
Many nutrition experts and psychologists think that it is the change in environment and the stress of a new beginning that cause the typical college freshmen to gain extra pounds. As students start a new stage of their lives, many eat to deal with the stress of change or loneliness. Often, college students are making meals or choosing foods independently for the first time in their lives. If they live in the college dormitory, they have a wide variety of foods to select from that may be higher in calories and fatter than the foods they consumed living at home. In addition, college social events usually center around food. I clearly remember sitting in my dorm cafeteria for two or three hours on a Saturday morning socializing with my new friends. Instead of eating only one meal, we would start with breakfast, eat throughout the duration of our socializing, and finish with lunch. Food also makes an appearance after late-night parties, as part of a school day, or simply to break the monotony(單調(diào) ).
So will this year's typical freshmen really gain 15 pounds? According to a 2006 Tufts University study, students enrolling in college this fall will gain weight, but maybe not the assumed 15 pounds. Based on the students surveyed, the study found that men can expect to gain an average of 6 pounds and women an average of 4.5 pounds during the freshman year.
【小題1】According to the passage, it is obvious that __________.

A．the foods the freshmen had at home may be healthier than those in the dorm cafeteria
B．to break the monotony, the students should start with breakfast, and finish with lunch
C．the students should eat to deal with the stress of change or loneliness in new situations
D．the boys may gain less pounds than the girls during the first year in the college
【小題2】 Nutrition experts and psychologists think that __________.
A．students should get used to the stress of change through foods they had at home
B．the new environment and the stress have something to do with the students' extra pounds
C．students should know in what way they gain so much weight
D．choosing foods independently can make people lose weight naturally
【小題3】From the writer's experience, the writer thinks that ____________.
A．foods in the dorm cafeteria are all higher in calories and fatter
B．the best way to break the monotony is through breakfast, lunch and supper
C．students in college will gain an average of about 5.25 pounds every fall
D．social events in the college are usually celebrated around food
【小題4】This passage is mainly about ______________.
A how and why the freshmen gain extra pounds  
B. the experience of the freshmen in the college
C. the freshmen with trouble in a new environment
D. the views of the nutrition experts and psychologists about gaining weight

From James Dean to Growing Pains, Hollywood has long had a love affair with the relationship between teens and their parents. As the fascination with this relationship attests, parents play a crucial role in the development of their children's personalities.
Teenagers learn by closely observing what people around them do. Parents are literally their first teachers and serve as role models. From hygiene to habits, from time management to personal manner, parents form the foundation of their children's characteristics. These tiny individual factors on our everyday behavior collectively constitute who we are.
A second influence occurs at the spiritual level. Parental treatment of children is reflected in children's relationship with others. For example, my dad was quite angry with my study habits a few years back and lost his temper.I clearly remember that I too would easily lose my cool and shout at people, often saying things I later regretted, in those difficult days.
Parents of my fellow classmates often tend to be anxious about the studies of their children, which can lead to a lack of confidence in their children. If we are boats weathering a storm as we navigate toward maturity, then parents should be our captains. It is as easy to lead us to shipwreck as is to take us ashore safely.
To be fair, the guidance and influence of our parents are not the sole factors in molding us. There are numerous examples of teens forging their own paths and becoming something of which their parents never dreamed. Even so, parents must be a fundamental force that positively influences their children. At their best, they can help to solve teenage problems with a respect for their children's thoughts.
【小題1】 James Dean and Growing Pains in the first paragraph are described as follows EXCEPT    .

A．they are about love affairs in family life
B．they are mentioned at the beginning of the passage to introduce the topic
C．they reflect a very important role parents play in childhood development
D．they are typical presentations of the relationship between teens and their parents
【小題2】 If parents are worried about the studies of their children, their children will      .
A．easily lose their temperB．lack self-confidence
C．follow their own pathsD．tend to shout at people
【小題3】 We can conclude from the passage that      .
A．teens will always be what their parents expect them to
B．parents' behavior influences their children both physically and mentally
C．the guidance and influence of parents are the only factor in molding teens
D．parents should be our captains when we teens are on boats in a storm
【小題4】 The passage is intended mainly for      .
A．teensB．teachersC．studentsD．parents
