你可能希望分享这些文章的人是出于开玩笑,我也是这么想的。但是我们不能:这个分析指出,通过一个近期的BuzzFeed和Ipsos的公众事务民调显示,75%的美国人(84%的共和党人以及71%的民主党人)很容易就被假新闻的标题所欺骗。这是关于真实性调查、理性思维、扎克伯格的自我意识的梦幻一年。
Whether of left or right, they present themselves as representatives of the common people against elites and unworthy outsiders; make a visceral connection with followers as charismatic leaders; manipulate that connection for their own advancement, frequently by lying egregiously; and threaten established rules of conduct and constraining institutions as enemies of the popular will that they embody.

Consider carrier screening

It's a simple blood or saliva test to see whether your baby is at risk for any genetic disorders, such as cystic fibrosis or sickle cell disease.

尽管每轮市场反弹最终都呈V形,每次连续的涨势中,个股的参与越来越少。今年春夏两季的绝大部分时间里,时事分析评论员们都专注于赢家与输家、大盘股和小盘股之间的明显差异。欧洲的通缩担忧以及日本的技术性衰退,使得分析师们愈加困惑,尽管美国经济正在好转,美国国库券收益率和通胀指标却双双下行。

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.
