   Several recent cases of violence（暴力）against students at U.S. colleges have made global headlines，arousing questions about the safety of America’s campuses. Yet government data show that the number of violent assaults（袭击）at colleges actually has decreased in recent years. And most schools have worked to increase safety through technology and student behavior.

It’s also important for students to take responsibility for their own safety. Being familiar with local neighborhoods and campus services is key. Personal-safety expert David Nance says the most important thing students can do is be attentive-which means not being distracted by smartphones or other devices.

The website for the group PEACE OUTSIDE CAMPUS，formed in response to the murder of a student from the University of Delaware in her off-campus apartment in 2005，lists additional measures students can take：

1. Don’t walk alone after dark or while drunk. Contact a friend to take you where you need to go.

2. When driving，keep your doors locked，and park in well-lit areas.

3. Don’t wear earphones or play music so loudly that you are unaware of your surroundings.

4. Trust your instinct（本能）and don’t worry about overreacting. You’re better safe than sorry.

5. Avoid entering elevators with strangers. When this is unavoidable，stand by the control panel and，if faced with a threatening way，push the emergency alarm and all the floor buttons. Don’t press the stop button.

6. Don’t hold the door open for a stranger attempting to enter the house，even if it seems rude. Ask them to identify themselves.

7. Post the police’s and fire departments’ numbers by every phone，and put them into your cellphone.

8. Label your emergency contacts as ICE（In Case of Emergency）in your cellphone so officials will know who to contact for important personal or medical information.

Many of us in developed societies【小题1】 (trap） in a spending circle. We work hard so that we can earn more money. Sometimes we try to deposit a little or change our money into different countries’ currencies in the hope of【小题2】 (make）even more money. But【小题3】 (strange） enough, the more money we earn, the less often we see it. Because we are taxpayers, the more we earn the more tax we should pay to those【小题4】govern us. In this spending circle, on the one hand, we accumulate【小题5】 (possess） but never feel like we have enough. On the other hand, we work hard for【小题6】 ( big） and better houses and cars but have no time to enjoy【小题7】 (they）. They seem like a big burden. There is a growing resistance to the consumer society which is especially affecting the youth of today. The government should make some laws.【小题8】laws came into being, a huge adjustment would be required and there would be diverse reactions. As【小题9】society, it's high time that we【小题10】 (take） these issues more seriously.

A new study has found that graduate students are six times more likely to show depression symptoms 【小题1】 the general population. Researchers led by Evans, a scientist, surveyed 2,279 students in 26 different 【小题2】 (country). Approximately 40% of the surveyed graduates scored middle 【小题3】 severe for anxiety. Nearly 40 percent of the surveyed graduates also showed signs of middle to severe depression. It’s not hard 【小题4】 (understand) why life as a master student can drive some people crazy. Long hours in researching, social loneliness and feelings of not being respected 【小题5】 (complete) can break even the most motivated persons among us. When this situation persists, the anxiety and depression can become part of their life. The relationship 【小题6】 their teachers is another aspect 【小题7】 can deeply influence a graduate student’s mental health. Among the graduates with anxiety or depression, only half agreed that their professional teachers 【小题8】 (provide) real help. These unbelievable high rates of anxiety and depression, when 【小题9】 (compare) to the general population, are alarming and should serve as 【小题10】 wakeup call for the academic world, expert Evans says.
