位居榜单第三的是史蒂夫·卡瑞尔(Steve Carell)。《卑鄙的我2》(Despicable Me 2)在今年大获成功,斩获票房9.19亿美元。该电影系列累计已取得14亿美元的全球票房,该系列第三部《小黄人》(Minions)也即将上映。卡瑞尔今年还出演了小制作独立影片《迷途知返》(The Way Way Back)和《超级魔术师》(The Incredible Burt Wonderstone)。后一部影片的票房虽未能赚回制作成本,但是我们这里只关注票房收入——该部影片为卡瑞尔2013年的电影票房收入又添2,250万美元。

但近2/3(65%)的福音派白人新教徒认为这些暴风雨是“末日”即将到来的证据,就如《圣经》中预言的那样。
近年来,大多数发达国家的排放量一直在逐步下降,这部分是因为不景气的经济形势,同时也是因为日益加强的气候政策。2013年,由28个国家组成的欧洲联盟(European Union)的排放量下降了1.8%,虽然德国和波兰等几个国家的耗煤量出现增加。英国、意大利和西班牙的排放量显著下降。

这一点毋庸置疑。从卫生间标志到时装秀,性别界线正在加速变得模糊。现在我们差不多该抛弃传统的“女孩用粉色,男孩用蓝色”的成见了。

对于精打细算的旅客来说,尼泊尔一直是绝佳的好去处。无论是该地区的徒步路线还是南部地区的野外生物,在世界范围内都是赫赫有名。平均每人每天的旅行花费大概只在50美元左右。

这个领域的创新速度非常快。自从Fitbit于2008年成立以来,各家公司已经发布了五到六个完全不同的产品。三星(Samsung)则在九个月内发布了可穿戴设备Galaxy Gear的三到四个衍生产品。索尼(Sony)、Pebble、谷歌和Facebook的头戴式虚拟现实设备Oculus Rift也紧随其后。
不过流行音乐更为广阔的世界也为我们带来了诸多乐趣,这些乐趣来自各个音乐领域的艺术家,例如像金发女郎乐队和托丽·阿莫斯这样的二十世纪的传奇人物,以及像杜阿·里帕和“Girl Ray”(女子射线)组合这样的新秀。

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.

While many games companies in the U.S., for example, charge subscription fees, most Chinese games utilize the free-to-play model, which allows players to try out a game without paying. The longer players stay in the game, the more likely they will be to pay for in-game items to move up into higher levels of play. But that also means that people who spend the most money are the best performers. [Accessed May 2019]
