蜀　相

杜 甫

丞相祠堂何处寻？锦官城外柏森森。

映阶碧草自春色，隔叶黄鹂空好音。

三顾频烦天下计，两朝开济老臣心。

出师未捷身先死，长使英雄泪满襟。

He Costa Rica to avoid military service.

村 行

杜牧

春半南阳西，柔桑过村坞。

娉娉垂柳风，点点回塘雨。

蓑唱牧牛儿，篱窥猜裙女。

半湿解征衫，主人馈鸡黍。

    While high school does not generally encourage students to explore new aspects of life, college sets the stage for that exploration. I myself went through this 1 process and found something that has changed my 2 at college for the better: I discovered ASL—American Sign Language(美式手语).

    I never felt an urge to 3 any sign language before. My entire family is hearing, and so are all my friends. The 4 languages were enough in all my interactions(交往). Little did I know that I would discover my 5 for ASL.

    The 6 began during my first week at college. I watched as the ASL Club 7 their translation of a song. Both the hand movements and the very 8 of communicating without speaking 9 me. What I saw was completely unlike anything I had experienced in the 10. This newness just left me 11 more.  

    After that, feeling the need to 12 further, I decided to drop in on one of ASL club's meetings. I only learned how to 13 the alphabet that day. Yet instead of being discouraged by my 14 progress, I was excited. I then made it a point to 15 those meetings and learn all I could.

    The following term, I 16 an ASL class. The professor was deaf and any talking was 17. I soon realised that the silence was not unpleasant. 18, if there had been any talking, it would have 19 us to learn less. Now, I appreciate the silence and the 20 way of communication it opens.  

2020 年，我在！

所谓“我在”，是“我在场”，是我在看，在听，在感受，在感动；所谓“我在”，是“有我在”，是对真理的追求，是对事业的坚守，是担当，是奉献，是人间大爱。所谓“我在”，是“我还在”，是国与民休戚与共，是你与我相濡以沫，是一个人给另一个人壮胆，是一群人为另一群人守护……

2020年，整个世界仿佛在历史的洪流里浮沉，前方仍可能是凛冽的冰河，是汹涌的怒涛……你我的命运从未如此与国家命运生死相连，你我的历史从未如此与世界历史紧密相系！我们目睹了 “大我”的不朽，也明白了 “小我”的价值。你有我们在，我们有你在，你有我们彼此在。

2020年，我在！ 2021年，在我！

    Exercise may help to safeguard the mind against depression through previously unknown effects on working muscles, according to a new study involving mice.

    Mental health experts have long been aware that even mild, repeated stress can contribute to the development of depression and other mood disorders in animals and people. Scientists have also known that exercise seems to cushion against depression. But precisely how exercise, a physical activity can lessen someone's risk for depression, a mood state, has been mysterious. So for the new study, researchers at the Karolinska Institute in Stockholm studied the brains and behavior of mice in a complicated and novel fashion.

    We can't ask mice if they are feeling cheerful or in low spirits. Instead, researchers have pictured certain behaviors that indicate depression in mice. If animals lose weight, stop seeking out a sugar solution when it's available — because, probably, they no longer experience normal pleasures — or give up trying to escape from the cold-water zone just freeze in place, they are categorized as depressed. And in the new experiment, after five weeks of frequent but low-level stress, such as being lightly shocked, mice displayed exactly those behaviors. They became depressed.

    The scientists could then have tested whether exercise blunts (延缓) the risk of developing depression after stress by having mice run first. But, frankly, from earlier research, they wanted to know how, so they bred pre-exercised mice. A wealth of earlier research by these scientists and others had shown that aerobic exercise, in both mice and people, increases the production within muscles of an enzyme (酶) called PGC-1alpha. The Karolinska scientists suspected that this enzyme somehow creates conditions within the body that protect the brain against depression. Then, the scientists exposed the animals, which without exercising, were in high levels of PGC-1alpha to five weeks of mild stress. The mice responded with slight symptoms of worry. But they did not develop depression. They continued to seek out sugar and fought to get out of the cold-water zone. Their high levels of PGC-1alpha appeared to make them depression-resistant. Finally, to ensure that these findings are relevant to people, the researchers had a group of adult volunteers complete three weeks of frequent endurance training, consisting of 40 to 50 minutes of moderate cycling or jogging. The scientists conducted muscle biopsies (活体检查) before and after the program and found that by the end of the three weeks, the volunteers' muscle cells contained substantially more PGC-1alpha than at the study's start. The finding of these results, in the simplest terms, is that “you reduce the risk of getting depression when you exercise,” said Maria Lindskog, a researcher at the Karolinska Institute.

    It is necessary to be reasonable and flexible enough to avoid conflicts as much as possible and live in peace with others. If you have done all your best to avoid conflicts and you are still arguing, then read these effective tips on how to avoid conflicts.

● Don't get in the center of the conflict.

    Sometimes people can get in the center of conflicts due to their enthusiasm for offering help. Frankly speaking, it is very unwise, because it can make you the main figure of the conflict. You should focus on your own life issues.

● Be kind.

    Life is full of conflicts and disagreements, that's why you should find more conservative ways of dealing with them. For example, kindness can lessen the conflict.

● Try to be a peacekeeper.

    Peacekeepers tend to cooperate with people without bad emotions which usually lead to arguments and even conflicts. “” This saying is the life motto of a natural-born peacekeeper. Don't worry if you are not a natural-born peacekeeper; you can gain this skill during life.

● Walk off.

    When the conflict is gathering pace and you can't manage to control yourself, you should choose to handle the situation in another way. By all means, try to keep yourself away from stress. You should get away from the situation for a while.
