7. D) The technology is too expensive.
【听力原文】
Genetic researchers in China have made a clone of a star police dog. The clone was born in a laboratory in Beijing in December. Tests show that the clone and her mother are almost identical genetically. The mother dog helped solve multiple murders and many other crimes. [5] The clone has already performed better than traditionally bred dogs on several tests.
[6] If the clone continues to perform as well as expected, it could mean a huge reduction in the training time for police dogs, which usually takes about five years.The ultimate goal of scientists is to produce clones of talented police dogs that can be trained in months instead of years.[7] However, this goal is not yet possible due to the current costs of the technology.
This is not the first time a clone has been made of a star police dog. In South Korea, six clones began working with the police in 2008.
【答案解析】
5. What do the researchers’tests show about the cloned dog?
研究人员针对克隆犬的试验表明什么？
答案：
D) It has done better than naturally born dogs.
它比自然出生的狗表现得更好。
解析：
新闻中提到，“The clone has already performed better than traditionally bred dogs on several tests.”在多项试验中，克隆犬的表现已经优于传统饲养的警犬。“traditionally bred dogs”对应选项D中的 “naturally born dogs”，因此选D。
干扰项分析：
A) It has helped solve several murder cases.
它帮助侦破了多起谋杀案。
新闻中提到“the mother dog helped solve multiple murders”，帮助侦破多起谋杀案的是克隆犬的母亲，而非克隆犬本身，故排除。
B) It has become a star police dog in Beijing.
它已成为北京的明星警犬。
新闻中提到“Genetic researchers in China have made a clone of a star police dog”中国的基因研究人员克隆了一只明星警犬，这句话是指这只克隆犬的母亲是明星警犬，但并未提及它已成为明星警犬，故排除。
C) It has surpassed its mother in performance.
它的表现超过了它的母亲。
新闻中提到克隆犬与母亲的基因几乎完全相同，且表现优于传统饲养的警犬，但并未直接比较克隆犬与其母亲的表现，故排除。
6. What is the scientists’purpose in cloning police dogs?
科学家克隆警犬的目的是什么？
答案：
D) To reduce their training time.
缩短训练的时间。
解析：
新闻中提到，“If the clone continues to perform as well as expected, it could mean a huge reduction in the training time for police dogs, which usually takes about five years.The ultimate goal of scientists is to produce clones of talented police dogs that can be trained in months instead of years.”如果克隆犬继续保持预期的良好表现，那就意味着警犬的训练时间将大大缩短，训练警犬通常需要五年左右的时间。科学家们的终极目标是培育出几个月就能训练好的而不是几年才能训练好的克隆天才警犬。可见，科学家培育克隆犬是为了缩短训练的时间，因此选D。
干扰项分析：
A) To speed up investigation into criminal cases.
加快犯罪案件的侦破。
新闻中虽然提到警犬母亲帮助侦破多起案件，但并未提及克隆警犬的目的是直接加快案件侦破速度，故排除。
B) To test the feasibility of cloning technology.
测试克隆技术的可行性。
新闻中提到这并非首次克隆明星警犬（韩国2008年已有先例），说明克隆技术的可行性已被验证，科学家克隆警犬的目的不是测试技术可行性，故排除。
C) To cut down training expenses.
减少训练开支。
新闻中提到了缩短训练时间，但并未直接提及减少训练开支，“expenses”一词在新闻中未出现，故排除。
7. Why does the news report say the scientists’goal is not yet possible?
为什么新闻报道说科学家的目标还不可能实现？
答案：
D) The technology is too expensive.
这项技术过于昂贵。
解析：
新闻后面提到，“However, this goal is not yet possible due to the current costs of the technology.”由于目前的技术成本，科学家们的终极目标还无法实现。“costs”即费用、成本，说明技术过于昂贵，因此选D。
干扰项分析：
A) Cloning is too complicated a process.
克隆过程过于复杂。
新闻中并未提及克隆过程复杂，故排除。
B) The technology is yet to be accepted.
这项技术尚未被接受。
新闻中提到韩国2008年已有克隆警犬投入工作，说明技术已被接受，故排除。
C) Cloning is ethically controversial.
克隆在伦理上有争议。
新闻中未提及伦理争议，故排除。
【参考译文】
中国的基因研究人员克隆了一只明星警犬。这只克隆犬于12月在北京的一个实验室出生。试验表明，克隆犬与它母亲的基因几乎完全相同。它的母亲帮助侦破了多起谋杀案和许多其他犯罪案件。在多项试验中，克隆犬的表现已经优于传统饲养的警犬。
如果克隆犬继续保持预期的良好表现，那就意味着警犬的训练时间将大大缩短，训练警犬通常需要五年左右的时间。科学家们的终极目标是培育出几个月就能训练好的而不是几年才能训练好的克隆天才警犬。然而，由于目前的技术成本，科学家们的终极目标还无法实现。
这并不是第一次克隆明星警犬。在韩国，六只克隆犬于2008年开始与警方合作。
