一份有關(guān)昆蟲(chóng)數(shù)量的科學(xué)審核報(bào)告顯示,世界上 40% 的昆蟲(chóng)物種數(shù)量正 “急劇下降”。這份報(bào)告稱,導(dǎo)致昆蟲(chóng)總數(shù)下降的原因是集約型農(nóng)業(yè)、使用殺蟲(chóng)劑以及氣候變暖。

Insects are the most abundant form of animal life on the planet, representing more than 17 times the weight of the entire human population.
昆蟲(chóng)是地球上數(shù)量最充足的動(dòng)物生命體,它們的重量之和相當(dāng)于整個(gè)人類(lèi)人口體重的 17 倍。
This study looked at 73 scientific reports. It found that overall, insect populations are falling by about 2.5% a year. 40% of the world's insects could be extinct within a few decades.
這份研究分析了 73 份科學(xué)報(bào)告。研究發(fā)現(xiàn),總體來(lái)講,昆蟲(chóng)的數(shù)量每年下降 2.5% 左右。世界上 40% 的昆蟲(chóng)有可能會(huì)在未來(lái)的幾十年里滅絕。
In some areas, the decline is even more rapid. According to one recent study, the number of ground insects in Puerto Rico has fallen by 98% over the last 35 years. A growing body of research shows that insects are declining about twice as fast as vertebrates.
在一些地區(qū),昆蟲(chóng)數(shù)量的下降速度更快。一項(xiàng)最新報(bào)告顯示,波多黎各的陸地昆蟲(chóng)數(shù)量已在過(guò)去的 35 年間下降了 98%。越來(lái)越多的研究表明,昆蟲(chóng)數(shù)量的下降速度大約是脊椎動(dòng)物的兩倍。
The report's authors say a rethinking of current agricultural practice is needed, in particular, a serious reduction in pesticide usage.
這份報(bào)告的作者們說(shuō),有必要重新審視當(dāng)前的農(nóng)耕方式,尤其應(yīng)著重減少殺蟲(chóng)劑的使用。

3. 答案
1. True or false? An increasing amount of research shows that insects are declining slower than vertebrates.

2. How many reports did the study look at?
The study looked at 73 reports.
3. What practices need a rethinking, according to the authors of the report?
Current agricultural practices, in particular, the amount of pesticide being used, need a rethinking, according to the authors of the report.
