纽约人向专栏提出的问题,不仅取决于他们的个人情况,还取决于当今的重大问题,比如住房成本上升、士绅化、豆腐渣工程。最终,2014年成为了一个一切都在增长的年份,增长的包括房价、租金,以及最重要的——楼盘数量。根据纽约房地产委员会(Real Estate Board of New York)的数据,10月批准建设的单元达到了16700套。

The bigger Tesla gets, the more complex its operations become. Since it sells directly to customers and eschews franchised dealers, it will have to develop a network of service centers to handle repairs on the cars it sells. Its unusually generous warranty, which obligates it to buy back used cars for 50% of their original base price after three years, could create a second channel of used Teslas. “Tesla will be eating a lot of three-year-old cars that aren’t as sexy or rare as they were a year ago,” wrote one Seeking Alpha blogger. ‘To me, it sounds like a potential mess.”

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.
