我们不妨借用一些狄更斯的名句,来回顾下几乎各种战略都失灵的2014年:
The federal control board has requested a revised fiscal plan that has to be approved by end of January, saying that the one Garcia submitted last year was in part unrealistic and relied too heavily on federal funds. Garcia had refused to submit a revised plan to include austerity measures. Rossello has said he would request an extension of that deadline as well as an extension of a moratorium that expires in February and currently protects Puerto Rico from lawsuits filed by angered creditors.
"Moreover, most Chinese families only have one child, so many of us return to China because we want to stay close to our family and friends," said a student surnamed Su, who gave up his job in the UK and returned to take care of his mother in China.

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.

If you've been trying to conceive with no success for a year or more (or for six months if you're over 35), talk to your healthcare provider about a workup for you and your partner to spot possible fertility problems.
