-  * The team fails to get a first down (i.e., in four downs they fail to move ten yards ahead of where they got their last first down). The defensive team takes over the ball at the spot where the fourth down play ends.+  * The team fails to get a first down (i.e., in four downs they fail to move ten yards ahead of where they got their last first down). The defensive team takes over the ball at the spot where the fourth-down play ends. 
 +  * The offense scores a touchdown or field goal. The team that scored then kicks the ball to the other team in a special play called a **kickoff**. 
 +  * The offense punts the ball to the defense. A **punt** is a kick in which a player drops the ball and kicks it before it hits the ground. Punts are nearly always made on a fourth down when the offensive team does not want to risk giving up the ball to the other team at its current spot on the field and feels it is too far from the other team's goalposts to attempt a field goal. 
 +  * A defensive player catches a forward pass. This is called an **interception**, and the player who makes the interception can run with the ball until he is tackled, forced out of bounds, or scores. 
 +  * An offensive player loses the ball (a **fumble**) before being tackled and a defensive player picks it up. As with interceptions, a player "recovering" a fumble can run with the ball until tackled or forced out of bounds. Lateral passes that are not caught, or caught by a defensive player, are considered fumbles. Lost fumbles and interceptions are together known as **turnovers**. In college rules, a player who recovers the ball by falling on it, may not advance the ball even if he has not been tackled. 
 +  * The offensive team misses a field goal attempt. In this case, the defensive team gets the ball at the spot where the previous play began or—in the NFL—at the spot of the kick. If the unsuccessful kick was attempted from within 20 yards of the end zone, the other team gets the ball at its own 20-yard line (that is, 20 yards from the end zone). 
 +  * The defense forces a "safety." If an offensive ball-carrier is tackled or forced out of bounds in his own end-zone—or loses the ball out of bounds there, or the offense commits certain penalties in the end-zone—the defense scores a "safety," worth two points. The offense must then kick the ball to the defense from its own 20-yard line. 
 +  * An offensive ballcarrier fumbles the ball forward into the end zone and then the ball goes out of bounds. This rare occurrence leads to a **touchback**, with the ball going over to the opposing team at their 20-yard line. (However, touchbacks during non-offensive special teams plays, such as punts and kickoffs, are quite common.)

 +  * 球队未能获得第一次进攻（即在四次进攻中，未能在最后一次进攻的位置前移10码）。防守一方可在最后一次进攻完结的地方开始反攻
 +  * 进攻队达阵得分或射门得分。得分的一方将球踢给另一方，这种特殊战术称为**开球**。
 +  * 进攻方将球踢给防守方。**弃踢**是指球员在球落地前将球丢弃并踢出的一种踢法。弃踢几乎都是在第四次进攻时进行的，这时进攻方不想冒着将球让给对方的风险，在当前场上的位置，并且觉得离对方的门柱太远，不能尝试射门。
 +  * 防守方的球员接到进攻方的传球，称之为**抄截**（又译为**拦截**）。拦截的球员可以带球跑，直到被擒抱、被迫出界或得分。
 +  * 进攻球员在被擒抱前丢球（即**掉球**），防守球员捡到球。与抄截一样，防守方拿到对方掉球可以实时反攻，直至被擒抱、出界或得分。没有接住的横向传球，或者被防守球员接住的横向传球，都被认为是失误。失误和抄截统称为**失误**。在大学比赛的规则中，倒地捡球的球员，即使没有被擒抱，也不能推进球。
 +  * 进攻的一方尝试射门失败。防守一方可在上一次开球处开始进攻（在NFL，是射门处）。如果射门处是底线前二十码之内，原防守一方在二十码线开始进攻。
 +  * 防守得到“安全分”。如果进攻方的持球人在自己的终结区被擒抱或被迫出界，或在终结区丢球出界，或进攻方在终结区犯了某些罚球，防守方就得一个安全分，价值2分。然后进攻方必须从自己的20码线把球踢给防守方。
 +  * 进攻型持球者将球向前带入底线，然后球出界。这种罕见的情况会导致**触地得分**，球会在对方20码线上越过对方。(然而，在非进攻性的特殊队伍的比赛中，如点球和开球，触地得分是很常见的。)

 +  * A **touchdown** is worth six points. It is scored when a player runs the ball into or catches a pass in his opponent's end zone.
 +  * A **//conversion//**. After a touchdown, the ball is placed at the other team's three-yard line (the two-yard line in the NFL). The team can attempt to kick it over the crossbar and through the goalposts in the manner of a field goal for one point (an **extra point** or **point after touchdown** (PAT)), or it may run or pass the ball into the end zone in the manner of a touchdown for two points (a **two-point conversion**).
 +  * A **field goal** (FG) is worth three points. It is scored by kicking the ball over the crossbar and through the goalposts. Field goals may be placekicked (kicked when the ball is held vertically against the ground by a teammate) or drop-kicked (extremely uncommon in the modern game). A field goal is usually attempted on fourth down instead of a punt when the ball is close to the opponent's goal line, or when there is little or no time left to otherwise score.
 +  * A **safety**, worth two points, is scored by the defense when a ball-carrier is tackled in his own end zone, etc., as explained above.

 +  * **达阵**得6分。当一名球员将球跑进对方的端区或接住对方的传球时，即可得分。
 +  * 一个**//转换//**。达阵后，球被放置在对方的三码线上（NFL的两码线）。球队可以尝试用射门的方式将球踢过横梁，穿过门柱，获得1分（加分或触地后得分），也可以用触地的方式将球跑进或传进底线，获得2分（两分转换）。
 +  * **射门**（简写为FG）得分得3分。它的得分方法是将球踢过横梁并穿过门柱。射门得分可以是定位球（当球被队友垂直贴地时踢出）或落踢（在现代比赛中极不常见）。当球接近对方球门线时，或当剩下的时间不多或没有时间得分时，通常会在第四次进攻中尝试射门而不是弃踢。
 +  * **安全球**，得2分，得分可由诸如当持球人在自己的端区被擒时、由防守方得分等等。

 +<div half column>
 +Each half begins with a kickoff. Teams also kick off after scoring touchdowns and field goals. The ball is kicked using a kicking tee from the team's own 30-yard line in the NFL and college football (as of the 2007 season). The other team's kick returner tries to catch the ball and advance it as far as possible. Where he is stopped is the point where the offense will begin its **drive**, or series of offensive plays. If the kick returner catches the ball in his own end zone, he can either run with the ball, or elect for a touchback by kneeling in the end zone, in which case the receiving team then starts its offensive drive from its own 20-yard line. A **touchback** also occurs when the kick goes out-of-bounds in the end zone. A kickoff that goes out-of-bounds anywhere other than the end zone before being touched by the receiving team results in a penalty. Unlike with punts, once a kickoff goes 10 yards, it can be recovered by the kicking team. A team, especially one who is losing, can try to take advantage of this by attempting an **Onside kick**. Punts and turnovers in the end zone can also end in a touchback.

 +每半场以开球开始。球队也会在达阵得分和射门得分后开球。在美国橄榄球联盟和大学橄榄球中，球是从球队自己的30码线上用踢球板踢出的（从2007赛季开始）。另一队的踢球回传者试图接住球并尽可能地推进。他被拦截的地方就是进攻方开始**进攻**的地点，或一系列的进攻战术。如果回踢队员在自己的端区接球，他可以选择带球跑，或者选择在端区跪下来选择达阵，在这种情况下，接球队从自己的20码线开始进攻。当球被踢出终点区界外时，也会发生**达阵**。开球在被接球队碰触前，在终点区以外的任何地方出界都会被判罚。与点球不同，一旦开球跑出10码，就可以由踢球队追回。一支球队，特别是输球的球队，可以尝试用**短踢**来取得优势。踢球和在终点区的失误也可以以触地得分结束。

 +=== Penalties - 处罚 ===
 +
 +<div group>
 +<div half column>
 +Rule violations are punished with **penalties** against the offending team. Most penalties result in moving the football towards the offending team's end zone. If the penalty would move the ball more than half the distance to the defense's end zone, the penalty becomes half the distance to the goal instead of its normal value. 
 +</div>
 +
 +<div half column>
 +违反规则的行为将使违规队伍受到**处罚**。大多数罚球的结果是将足球移动到犯规队的端区。如果罚球将使球移动到防守队端区的距离超过一半，则罚球将变成到球门距离的一半，而不是通常的距离。
 +</div>
 +</div>
 +
 +<div group>
 +<div half column>
 +Most penalties result in replaying the down. Some defensive penalties give the offense an automatic first down. Conversely, some offensive penalties result in the automatic loss of a down. If a penalty gives the offensive team enough yardage to gain a first down, they get a first down, as usual. 
 +</div>
 +
 +<div half column>
 +大多数罚球的结果是重档。一些防守罚球使进攻者自动获得第一次进攻。相反，一些进攻罚球会导致自动失去一攻。如果罚球给进攻队带来足够的码数来获得一攻，他们就会像往常一样获得一攻。

 +<div group>
 +<div half column>
 +If a penalty occurs during a play, an official throws a yellow flag near the spot of the foul. When the play ends, the team that did not commit the penalty has the option of accepting the penalty, or declining the penalty and accepting the result of the play. 
 +</div>
 +
 +<div half column>
 +如果在比赛中发生了罚球，一位裁判员会在犯规地点附近抛出黄旗。当比赛结束时，没有罚球的一方可以选择接受罚球，或者拒绝罚球并接受比赛结果。
