“10米折返跑”的成绩反应了人体的灵敏素质。测定时，在平直跑道上，受试者以站立式起跑姿势站在起点终点线前，当听到“跑”的口令后，全力跑向正前方10米处的折返线，测试员同时开始计时。受试者到达折返线处时，用手触摸折返线处的物体（如木箱），再转身跑向起点终点线，当胸部到达起点终点线的垂直面时，测试员停表，所用时间即为“10米折返跑”的成绩。设受试者起跑的加速度为4m/s²，运动过程中的最大速度为4m/s，快到达折返线处时需减速到零，减速的加速度为8m/s²，返回时达到最大速度后不需减速，保持最大速度冲线。求该受试者“10米折返跑”的成绩为多少秒？

A good translator is by definition bilingual. The opposite is not (1) true, however. A born and bred bilingual will still need two (2) to become a translator: first, the skills and experience necessary for (3) ; second, knowledge of the field in which he or she will (4) . The skills and experience for translation include the ability to write (5) in the target language, the ability to read and understand the (6) language material thoroughly, and the ability to work with the latest (7) and communication hardware and software.
Does a born and bred bilingual (8) a better translator than someone who learned language B later in (9) There is no definite answer, but the following issues are important. (10) , a born and bred bilingual often suffers from not truly knowing (11) language well enough to translate, with some even suffering from what (12) known as a lingua-ism, a state in which a person lacks (13) full, fluent command of any language. Second, born and bred bilinguals (14) don’t know the culture of the target language well enough to (15) top-quality translations, or cannot recognize what aspects of the source language (16) its culture need to be treated with particular care, as they (17) in a sense too close to the language. And last, they often (18) the analytical linguistic skills to work through a sticky text.
On (19) other hand, the acquired bilingual may not have the sam0e in-depth (20) of colloquialisms, slang, and dialect that the born bilingual has. Also, the acquired bilingual will not be able to translate as readily in both directions (from B to language A and A to language B). Finally, born bilinguals often have a greater appreciation of the subtleties and nuances of both their languages than someone who learns their B language later in life can ever hope to have.
