Last Monday our class went on a(n)(organize) trip to a forest to study the wildlife. We planned to have our picnic lunch in the forest next to a(n)(fall)tree, but the terrible smell given off by a (pollute) river made us feel sick. We searched the forest for the polluter (污染源), and found an unknown factory (pour) waste water into the river. We all thought it was a serious problem and one solution (suggest) by our class was to close the factory as soon as possible.

Denis Mukwege never planned to become Dr Miracle, an award­winning doctor. He grew up in the Democratic Republic of the Congo (DRC) (刚果民主共和国). In fact, it was visiting the sick with his father that made him want to become a doctor in the first place.

The country has experienced more than twenty years of fighting and Congolese women have suffered the worst. In order to control the country's valuable mineral deposits (矿床), rebel (反叛) groups are attacking women in the area.

One man stands strongly against this huge harm. He first set up Panzi Hospital made of tents (帐篷) in 1999. After losing the hospital the same year in the crossfire of the Second Congo War, Mukwege rebuilt it the following year. Since then, Panzi Hospital has grown to a major health centre. There, Mukwege reportedly cares for more than 3,500 women a year, sometimes performing as many as 10 operations a day.

Year after year, Mukwege puts his life on the line to help injured women. In 2012, Mukwege's devotion to this cause was tested after almost being killed and his daughters being taken hostage (人质). He and his family escaped to safety in Sweden and then to Belgium. Thanks to a movement by local Congolese women who raised money for a return ticket, the doctor was able to go home. Although Mukwege went back to the DRC, he was forced to live inside the hospital under the protection of UN peacekeepers.

When operating in the hospital, Mukwege heard the news that he, along with Nadia Murad, had been awarded the 2018 Nobel Peace Prize. "When I see how strong women are，" Mukwege said, "all my energy comes. Winning the Nobel Peace Prize could be the first step towards an end to violence against women."

The secret to happiness is keeping busy, research has found. Keeping the mind occupied with tasks—no matter how meaningless—keeps off negative feelings, the study found.

However, the bad news is that humans seem hard­wired (天生的) to be lazy in order to save energy, according to Professor Christopher K. Hsee, a behavioural scientist at the University of Chicago.

In a study, 98 students were asked to complete two surveys. After they have completed the first they were made to wait 15 minutes to receive the next one.

They were given a choice of either handing in the first survey nearby or at a more distant location they had to walk to. Whichever option they chose, they would receive a chocolate bar. It turned out that approximately two­thirds(68 students) chose the lazy option. Those who had taken the walk reported feeling happier than those who had stayed.

Prof. Hsee concluded keeping busy helped keep people happy. He said the finding, reported in the journal Psychological Science, had political implications (可能的影响).

"Governments may increase the happiness of lazy citizens by having them build bridges," he proposed.

At the individual level, he advised, "Get up and do something. Even if there really is no point in what you are doing, you will feel better for it." He added, "Incidentally, thinking deeply or engaging in self­reflection can be regarded as keeping busy, too."

"You do not need to be running around. You just need to be engaged, either physically or mentally."

Ambition (志向、抱负) is a necessary quality in life. It is the force which drives us on to use whatever talent we have got. ， these talents will not be used for our own and others' benefit. Without ambition we are just jellyfish that flop through life. We only react to events: we don't try to control them.

. First of all, it can be unrealistic. We may not be able to see the limits of our own abilities, so we do ambitious things that are completely beyond us. Some people can see our good qualities and our limitations objectively. They may tell us that we haven't the ability. We refuse to take their evaluation. We keep on trying. Many years and many disappointments later we are forced to accept their judgment. But what a waste of time our ill­founded ambition has caused us!

Besides, our ambition can be too concentrated. We devote our attention to one narrow aim, such as getting distinctions in our science subjects. Everything that may draw us away from this aim is cut out of our lives. In the end we get our distinctions. But we are isolated beings who only care about particular examinations. And we probably won't make good scientists .

And our ambition can be limited to lifeless objectives. . Persons who feel inferior try to make up by seeking the respect of others through owning these artificial signs of worth.

. But, like all blind forces, it must be directed if not to cause disaster.

It's Global Youth Service Day, the largest youth service and citizen movement in the world and the only one that celebrates the contributions (make) by all youth aging from 5 to 25 through service.

The Youth Engagement Team of United Way of Central Indiana is taking (act) to advance the common benefits. When members found out that a small, rural town about 30 minutes northwest of Indianapolis, had the (high) percentage of financially stressed households in the area, they decided to do something about it. Since the town doesn't have a public library, the team built a little free library, and prepared 100 snack bags with notes of encouragement words inside for kids involved in the after­school program We All Matter. The (child) will receive not only food for (they) bodies, but food for their minds as well, as the team is also donating books (get) the library up and running.

Serving a young age promotes healthy lifestyles and choices, teaches life skills, (improve) the community and encourages lifelong moral rules of giving. Are you ready to join youth like these in making difference? Youth Service America offers excellent resources and your local United Way can point youth to the people and places need your support.
