无人驾驶汽车是当下炒作得最火的行业,这类汽车的倡导者已成为冗词赘语的世界级领军人物。埃隆?马斯克(Elon Musk)自称“要在一个安全系数超出人工驾驶数量级倍数的一体化平台上专注于全自动驾驶的实现”。(就是说特斯拉肯定能防止车祸的发生)。
20. Best Advice for Movie Lovers In August, the scholar Wheeler Winston Dixon sounded an alarm: “If you go on Amazon and you see some great black-and-white film, and it’s going for $3, or any kind of foreign or obscure film, buy it, because it’s going out of print, and they’re not going to put them back into print.” Tens of thousands of films that were on VHS never made the jump to DVD or to Blu-ray, Mr. Dixon warns.

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.
