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

Supporters claim that there are many _______ of service learning. Perhaps most importantly, students are forced to think _______ their own interests and become _______ of the needs of others. Students are also able to learn real­life skills that _______ responsibility, problem­solving, and working as part of a team. ________ students can explore possible careers ________ 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.

________ there are many benefits, opponents ________ problems with the new requirement. First, they ________ that the main reason students go to school is to learn core subjects and skills. Because service learning is time­consuming, students spend ________ time studying the core subjects. Second, they believe that forcing students to work without ________ 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 ________ to the community, learn new skills, and explore different careers. ________, I don’t believe you should force people to help others — the ________ to help must come from the heart. I think the best ________ 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.

8 . I was in the middle of the Amazon (亚马逊) with my wife, who was there as a medical researcher. We flew on a small plane to a faraway village. We did not speak the local language, did not know the customs, and more often than not, did not entirely recognize the food. We could not have felt more foreign.

We were raised on books and computers, highways and cell phones, but now we were living in a village without running water or electricity It was easy for us to go to sleep at the end of the day feeling a little misunderstood.

Then one perfect Amazonian evening, with monkeys calling from beyond the village green, we played soccer. I am not good at soccer, but that evening it was wonderful. Everyone knew the rules. We all spoke the same language of passes and shots. We understood one another perfectly. As darkness came over the field and the match ended, the goal keeper, Juan, walked over to me and said in a matter-of-fact way, “In your home, do you have a moon too?” I was surprised.

After I explained to Juan that yes, we did have a moon and yes, it was very similar to his, I felt a sort of awe (敬畏) at the possibilities that existed in his world. In Juan’s world, each village could have its own moon. In Juan’s world, the unknown and undiscovered was vast and marvelous. Anything was possible.

In our society, we know that Earth has only one moon. We have looked at our planet from every angle and found all of the wildest things left to find. I can, from my computer at home, pull up satellite images of Juan’s village. There are no more continents and no more moons to search for, little left to discover. At least it seems that way.

Yet, as I thought about Juan’s question, I was not sure how much more we could really rule out. I am, in part, an ant biologist, so my thoughts turned to what we know about insect life and I knew that much in the world of insects remains unknown. How much, though? How ignorant   (无知的) are we? The question of what we know and do not know constantly bothered me.

I began collecting newspaper articles about new species, new monkey, new spider…, and on and on they appear. My drawer quickly filled. I began a second drawer for more general discoveries: new cave system discovered with dozens of nameless species, four hundred species of bacteria found in the human stomach. The second drawer began to fill and as it did I wondered whether there were bigger discoveries out there, not just species, but life that depends on things thought to be useless, life even without DNA. I started a third drawer for these big discoveries. It fills more slowly, but all the same, it fills.

In looking into the stories of biological discovery, I also began to find something else, a collection of scientists, usually brilliant occasionally half-mad, who made the discoveries. Those scientists very often see the same things that other scientists see, but they pay more attention to them, and they focus on them to the point of exhaustion (穷尽), and at the risk of the ridicule of their peers. In looking for the stories of discovery, I found the stories of these people and how their lives changed our view of the world.

We are repeatedly willing to imagine we have found most of what is left to discover. We used to think that insects were the smallest organisms (生物), and that nothing lived deeper than six hundred meters. Yet, when something new turns up, more often than not, we do not even know its name.

9 . For those who can stomach it, working out before breakfast may be more beneficial for health than eating first, according to a study of meal timing and physical activity.

Athletes and scientists have long known that meal timing affects performance. However, far less has been known about how meal timing and exercise might affect general health.

To find out, British scientists conducted a study. They first found 10 overweight and inactive but otherwise healthy young men, whose lifestyles are, for better and worse, representative of those of most of us. They tested the men’s fitness and resting metabolic (新陈代谢的) rates and took samples (样品) of their blood and fat tissue.

Then, on two separate morning visits to the scientists’ lab, each man walked for an hour at an average speed that, in theory, should allow his body to rely mainly on fat for fuel. Before one of these workouts, the men skipped breakfast, meaning that they exercised on a completely empty stomach after a long overnight fast (禁食). On the other occasion, they ate a rich morning meal about two hours before they started walking.

Just before and an hour after each workout, the scientists took additional samples of the men’s blood and fat tissue.

Then they compared the samples. There were considerable differences. Most obviously, the men displayed lower blood sugar levels at the start of their workouts when they had skipped breakfast than when they had eaten. As a result, they burned more fat during walks on an empty stomach than when they had eaten first. On the other hand, they burned slightly more calories (卡路里), on average, during the workout after breakfast than after fasting.

But it was the effects deep within the fat cells that may have been the most significant, the researchers found. Multiple genes behaved differently, depending on whether someone had eaten or not before walking. Many of these genes produce proteins (蛋白质) that can improve blood sugar regulation and insulin (胰岛素) levels throughout the body and so are associated with improved metabolic health. These genes were much more active when the men had fasted before exercise than when they had breakfasted.

The implication of these results is that to gain the greatest health benefits from exercise, it may be wise to skip eating first.
