一個通過重新訓(xùn)練人體免疫系統(tǒng)并減緩1型糖尿病惡化的開創(chuàng)性療法首次試驗(yàn)結(jié)果為“安全”。導(dǎo)致患1型糖尿病的原因是胰腺內(nèi)控制血糖水平的 Beta 細(xì)胞遭到破壞。研究人員們觀察了在英國接受該免疫療法的27名患者，其病情的惡化速度均呈現(xiàn)下降的趨勢。但要想證實(shí)該療法的功效，科學(xué)家們?nèi)孕柽M(jìn)行更大規(guī)模的試驗(yàn)。請聽報(bào)道。
For now, there's no cure for type 1 diabetes. It’s caused by a rogue immune system destroying the beta cells in the pancreas that control blood sugar levels.
The immunotherapy tries to stop that happening by training the immune system to protect the beta cells. It was shown to be safe in tests on 27 people at the National Institute for Health Research Biomedical Research Centre in London.
There were also early signs the therapy was working. There were changes in the immune system and patients did not need to increase their insulin doses during the study. Professor Mark Peakman, who is leading the trial, said larger studies were still needed.
The diabetes charity JDRF said even the early-stage findings were exciting and could lead to a time when people no longer have to inject insulin every day.

答案
1. What is the cause of type 1 diabetes, according to the text?
The cause of type 1 diabetes is a rogue immune system that destroys the beta cells in the pancreas that control blood sugar levels.
2. How does the immunotherapy work?
The immunotherapy tries to train the immune system to protect the beta cells.
3. True or false? Patients needed to increase their insulin dose during the test.
False. Patients did not need to increase their insulin doses during the study.
4. Which word in the text means ‘a(chǎn) test over a period of time on whether something works effectively’?
Trial.
