VOA常速英语:WHO Says TB Blood Test Inaccurate

短语讲解：

1. It is based on two recent studies that found the commonly-used test to be unreliable and misleading -- and even a possible contributor to TB transmission.

base on使建立在…基础上
例句：Action should be based on solid facts.
行动应有确凿的事实为依据。

2. In fact, the studies that prompted the WHO action were done in India, where researchers argued the blood tests have contributed to increasing the number of TB infections in the country.

contribute to促成
例句：Smoking is a major factor contribute to cancer.
吸烟是致癌的一个重要因素。

3. They blamed the inaccuracy of the test for this outcome, saying an undetected, and untreated, case means the infected person can continue to infect others.

blame for因…怪罪, 责怪(某人)
例句：He blamed his brother for breaking the window.
他责备他兄弟打破了窗玻璃。

4. The WHO says more than a million of the tests are carried out each year, even though they are not approved by any recognized regulatory body.

carry out实行，执行；实现，完成
例句：He carried out the plan in very detail.
他一丝不苟地执行那项计划。

5. What these tests do is they measure antibodies in the blood against TB so any time anyone has been infected with TB at any time in their life they will develop antibodies against TB.

be infected with感染,沾染上
例句：He is infected with malaria.
他感染到疟疾。

6. But the problem is that one person’s antibodies are not going to be the same as the other person.

the same as与…同样的
例句：Twins look the same as each other
双胞胎看上去长得一样。

7. After the WHO issued its guidelines, the Indian government issued a statement urging doctors and labs not to rely on these imprecise diagnostic tests.

rely on信赖, 依赖
例句：Hong Kong's prosperity relies heavily on foreign businesses.
香港的繁荣在很大程度上依赖于外国商行。
