    The requirements for high school graduation have just changed in my community. As a result, all students must         1        sixty hours of service learning,         2        they will not receive a diploma. Service learning is academic learning that also helps the community.         3       of service learning include cleaning up a polluted river, working in a soup kitchen, or tutoring a student.        4       a service experience, students must keep a journal and then write a        5       about what they have learned.

    Supporters claim that there are many         6       of service learning. Perhaps most importantly, students are forced to think         7       their own interests and become        8       of the needs of others. Students are also able to learn real­life skills that         9        responsibility, problem­solving, and working as part of a team.         10        students can explore possible careers         11        service learning. For example, if a student wonders what teaching is like, he or she can choose to work in an elementary school classroom a few afternoons each month.

            12        there are many benefits, opponents         13        problems with the new requirement. First, they         14        that the main reason students go to school is to learn core subjects and skills. Because service learning is time­consuming, students spend         15        time studying the core subjects. Second, they believe that forcing students to work without         16        goes against the law. By requiring service, the school takes away an individual's freedom to choose.

    In my view, service learning is a great way to         17        to the community, learn new skills, and explore different careers.         18       , I don't believe you should force people to help others — the         19        to help must come from the heart. I think the best         20        is one that gives students choices: a student should be able to choose sixty hours of independent study or sixty hours of service. Choice encourages both freedom and responsibility and as young adults, we must learn to handle both wisely.

（一）

    Let's face it. No one drinks diet sodas for the taste. People drink diet sodas in the hope that it will help them lose weight or at least keep them from gaining it. Yet it seems to have exactly the opposite effect, according to a new study.

    Researchers from the University of Texas said those who drank two or more diet sodas a day had waist size increases that were six times greater than those who didn't drink diet sodas. ＂What we saw was that the more diet sodas a person drank, the more weight they were likely to gain,＂ said Sharon Fowler.

The study was based on data from 474 participants in a large, ongoing research project, where the participants were followed for nearly 10 years.

    While the findings are surprising, they also offer some explanations.

    Nutrition expert, Melanie Rogers, who works with overweight patients in New York, has found that when patients are switched from regular to diet sodas, they don't lose weight at all. ＂We weren't seeing weight loss necessarily, and that was confusing to us,＂ said Rogers.

    So why would diet soda cause weight gain? No one knows for sure yet, but it could be that people think they can eat more if they drink diet sodas, and so over-compensate for the missing calories.

    A related study found some sweeteners (甜味剂) raised blood sugar levels in some mice. ＂Data from this and other potential studies suggest that the promotion of diet sodas and artificial sweeteners may be risky,＂ said Helen P. Hazuda, professor at the University of Texas's school of medicine. ＂They may be free of calories, but not of consequences.＂

（1）People drink diet sodas to ____________.           

A.enjoy its taste   B.stay in fashion    C.achieve weight loss     D.gain more energy

（2）The new study suggests that drinking diet sodas ____________.           

A.causes people to become heavier

B.helps people to be healthier

C.makes people much thinner

D.offers people more calories

（3）We can learn from the passage that ____________.           

A.regular sodas make people lose more weight

B.diet soda drinkers tend to eat more food

C.diet sodas do help reduce calories

D.most blood diseases come from diet sodas

（4）The underlined word ＂They＂ in the last paragraph probably refers to ＂____________＂.           

A.sweeteners       B.diet sodas and artificial sweeteners

C.sodas            D.diet soda drinkers and sweetener takers

（二）

    There are lots of insects that farmers hate. But there also are some they like. They protect crops against damage from other insects. A good example is the lady beetle, which is also known as the ladybug(瓢虫)．

    Lady beetles are a natural control for aphids(蚜虫). Lady beetles are red, orange or black. They often have black spots, though some have light colored spots. Different kinds of lady beetles have different numbers of spots. There are lady beetles with four, five, seven and fourteen spots.

    Many of the well-known kinds of lady beetles come from Asia or Europe. They now are common throughout the United States.

    American scientists imported one kind of lady beetle, the multicolored Asian lady beetle, as early as 1916. They released them as an attempt to control some kinds of insects. Over the years, the beetle has become established, possibly helped by some that arrived with imported plants on ships.

    Experts say over 450 kinds of lady beetles are found in North America. Some are native to the area. Others have been brought from other places. Almost all are helpful to farmers.

    The Asian lady beetles now in the United States probably came from Japan. The Asian lady beetle eats aphids that damage crops like soybeans, fruits and berries.

    In the southern United States, Asian lady beetles have reduced the need for farmers to use reskilling poisons on pecan trees. This popular tree nut suffers from aphids and other pests that the lady beetles eat.

    But some people say the Asian lady beetle has itself become a pest. They worry that the lady beetles may eat their late autumn fruit crops.

    Experts say Asian lady beetles may appear in large numbers in some years. But they say the insects are too helpful to be considered as pests.
