Part B

Directions:

The following paragraphs are given in a wrong order. For Questions 41-45, you are required to reorganize these paragraphs into a coherent text by choosing from the list A-G to fill in each numbered box. The first and the last paragraphs have been placed for you in Boxes. Mark your answers on ANSWER SHEET1. (10 points)

[A] Ten volunteers responded to the placebo much better than the rest. By the end of the experiment, their anxiety scores had halved, whereas the others\' stayed the same. Brain scans also showed that activity in the amygdala, the brain\'s "fear" centre, had dropped by 3 per cent。

[B] He and his colleagues recruited 25 people with an exaggerated fear of public humiliation, otherwise known as social anxiety disorder. Participants had to give a speech at the start and end of an eight-week treatment - which unbeknownst to them and their doctors, was actually a placebo。

[C] To see if there were genetic differences between responders and non-responders, Furmark screened them for a variant of the gene for tryptophan hydroxylase-2, which makes the brain chemical, serotonin. Previous studies suggested that people with two copies of a particular "G" variant are less anxious in standard "fear" tests. Sure enough 8 of the 10 responders had two copies, while none of the non-responders did (Journal of Neuroscience (DOI: 10.1523/JNEUROSCI.2534-08.2008)。

[D] The gene might not play a role in our response to treatment for all conditions, and the experiment involved only a small number of people. Nonetheless, the discovery is a milestone in the quest to understand this phenomenon, which often blurs the results of clinical trials "To our knowledge, it\'s the first time anyone has linked a gene to the placebo effect," says Tomas Furmark of Uppsala University in Sweden。

[E] Furmark believes the effect of the gene may extend to other conditions where the amygdala is involved, such as phobias, pain disorders and even depression. However, he cautions that only further studies will reveal whether the gene influences the placebo effect more generally。

[F] Echoing Furmark\'s caution is Fabrizio Benedetti of the University of Turin, Italy. "We know that there\'s not a single placebo effect but many." Some may work through genetics, he adds, others through the expectation of a reward。

[G] FOR the first time, a gene is being linked to increased susceptibility to the placebo effect, the mysterious capacity some people have to benefit from sham treatments。
