在是非题的判断中，中国考生经常会认为只有原文和题目信息在某种成分上有稍微的差别就肯定不能选TURE,而是NOT GIVEN,而英国人在命题的时候只要两句话大意或考点的方向性相同就认为是TURE.
TURE
1.考点方向一致原则
EXAMPLE:
原文：This product is not harmful to enviroment.
题目：This product is enviromentally friendly.
分析：两句主语均为this product. 所以考点明显是在表语上。两句话是在判断this product对envirment得影响，原文not harmful to 对enviroment的影响的方向是正向的。friendly也为正向词，所以是TRUE.
2.推断或归纳原则
EXAMPLE:
原文：For example, it has been demonstrated rapid reponse leads to a greater likelihood of arrest only if reponses are in the order of 1-2 mintues aftter a call received by the police. When response times licrease to 3-4 minutes-still quite a rapid response-the likelihood of an arrest is substantially reduced.
题目：A response delay of 1-2 minutes may have substantial influence on whether or not a suspected criminal is caught.
分析：原文的两句可以推断出：1-2分钟，抓住罪犯的可能性很大;3-4分钟，可能性就实质性地降低。题目的判断“1-2”分钟的反应延迟会对疑犯是否被抓住产生实质性的影响，为原文信息的直接判断，所以为TRUE.
