The big family migrate between winter tropical breeding areas (North West Shelf, Great Barrier Reef, New Caledonia, Vanuatu, Fiii, Tonga) and summer Antarctic feeding areas. Once mon in New Zealand waters, humpbacks are now rarely seen and may migrate further offshore. Males pete for mates either by physical fight or by song.

Now there is no cure for HIV/AIDS though there have been developments in oral drug treatments to slow the progression of the disease” 可知，“2017年全世界有近3700萬人感染艾滋病毒。研究人員表示，這一“突破性”的發(fā)現(xiàn)是“現(xiàn)在唯一的”以低成本為發(fā)展中國(guó)家生產(chǎn)抗艾滋病毒聯(lián)合治療的方法，但還有待于進(jìn)一步的完善。A social webpage.D.A biology textbook.B.It still requires perfecting.D.It can prevent infections of HIV.B.By attaching it to the HIV virus.D.By transforming it into proteins.B.Remind readers of HIV prevention.D.Stress the urgency of HIV treatments.B. They say the easiest and most costeffective way to use the rice will be to make it into a cream to be put on the skin. The HIVfighting proteins can then enter the body through the skin. People all over the world could grow the rice and make the cream themselves. This would prevent the cost and travel required for many patients to receive treatments and medicine. The Joint United Nations Program on HIV/AIDS reports that worldwide, nearly 37 million people were living with HIV in 2017. The organization says the largest number of those are in developing countries. Nearly twothirds of HIV cases are in Africa. Now there is no cure for HIV/AIDS though there have been developments in oral drug treatments to slow the progression of the disease. According to a recent study, a new genetically modified rice can prevent infections of HIV, the virus responsible for the disease AIDS. 【點(diǎn)評(píng)】本題考點(diǎn)涉及細(xì)節(jié)理解和推理判斷兩個(gè)題型的考查，是一篇科普類閱讀，考生需要準(zhǔn)確捕捉細(xì)節(jié)信息，并根據(jù)上下文進(jìn)行邏輯推理，從而選出正確答案。從而可以推斷出，千足蟲是擁有多種防御機(jī)制的物種。然而，它們也會(huì)釋放出有害 的 （3）考查推理判斷。t have to fax anyone a death certificate.
