The US team say the results, published in Nature, are striking and should encourage research efforts. such as pregnant women 173。 Now, developing a vaccine for pregnant women to protect their unborn babies is an international research priority(優(yōu)先事項(xiàng)). US scientists from the Walter Reed Army Institute of Research, the Beth Israel Deaconess Medical Center and Harvard Medical School tested two types of Zika vaccine in mice – one based on bits of genetic(基因的) code from the virus and another that is an inactive (and therefore harmless) copy of Zika. Both worked well, protecting every mouse that was immunised against the virus. In parison, all of the mice not given the vaccine caught Zika after they were exposed to it.based vaccines. Of course, future tests will need to check the vaccine is safe and effective in humans, as well as how long the immunity might last.（1）If the tests in humans go smoothly, a vaccine for use in the laboratory will be still be years away.B.a licensed vaccine will still not be accessible in a short term.D.many countries are actively involved in the research of the Zika vaccine.B.None of the mice given the vaccine caught Zika.D.Zika vaccine 39。 in miceB.International researches into Zika have paid offD. （1）考查細(xì)節(jié)理解。 such as pregnant women 173。 （2）考查細(xì)節(jié)理解。 （3）考查主旨大意。 【點(diǎn)評】本題考點(diǎn)涉及細(xì)節(jié)理解和主旨大意兩個(gè)題型的考查，是一篇科研類閱讀，考生需要準(zhǔn)確掌握細(xì)節(jié)信息，同時(shí)根據(jù)上下文進(jìn)行推理，歸納，從而選出正確答案。 You know those nutrition guidelines the government issues every few years?

Most of the reductions e from meat and dairy, which have an outsized impact on land use and pollution, and are a major source of greenhouse gases.(That39。 Overall, in high173。s team estimates that following the rules could result in as much as a 17 percent reduction in land use, a 21 percent reduction in nutrient pollution, and a 25 percent drop in agricultural greenhouse gas emissions. Cutting down on how much food we waste—which is roughly a third in the US—could help even more.
