答:英雄是一个不想成为英雄的人。英雄是那种明明完全可以选择,但却选择在那个时刻承担起责任的人。那就是英雄所要做的事。举个例子,在911实践中,飞机上的一些乘客曾经和恐怖分子搏斗。在福岛辐射泄露实践中,有些人前往当地试图修理核电站,并且因此而死。但他们必须这么做。他们是英雄。他们想要的并不是“当英雄”,而是承担责任,做正确的事。

Pregnancy symptoms during week 4

No symptoms?

Don't worry. Many women don't feel anything yet this week. In fact, most early pregnancy symptoms don't start until about 6 weeks.

Tender, swollen breasts

Breast tenderness can be one of the earliest signs of pregnancy. It usually starts around 4 to 6 weeks and lasts through the first trimester.

Fatigue

For many women, exhaustion is one of the first signs of pregnancy. But other women hardly seem to slow down at all.

Nausea or vomiting

Morning sickness can strike at any time of day. It usually starts around 6 weeks of pregnancy but can begin as early as 4 weeks. Some women have cramping as well.

Pregnancy checklist at 4 weeks pregnant

Take a pregnancy test

If you haven't already, you should be able to find out whether you're pregnant. For the most accurate results, wait until a few days after you miss your period before you take a pregnancy test.

Make a prenatal appointment

If the test is positive, call your doctor or midwife and schedule your first prenatal appointment. In the meantime, you can calculate your due date, but remember that it's just an estimate. You're just as likely to go into labor any day during the two weeks before or after.

The Great Recession had devastating effects across the U.S. and few places were as hard hit as Arizona. The state was booming on the strength of its tourism and real estate markets during the 2000s. Median home prices jumped 70% between 2003 and 2006—only Nevada had bigger gains—fueling more building and construction jobs. Monthly unemployment was at 3.5% through much of 2007. But then the bottom fell out. Home prices plummeted more than 50% from their peak and 6% Arizona properties received foreclosure filings in 2009. Unemployment stubbornly remained in double-figures for most of 2009 and 2010 and only Nevada lost a higher percentage of jobs over the last five years. Household incomes declined at the fastest rate in the country since 2008. [Accessed May 2019]
