Thousands of workers are busy preparing pavilious（展览馆）and gardens for the International Horticultural Exibition(世园会)2019 in Beijing , as fewer than 30 days remain until the opening.

The expo park(展会园区)【小题1】 （locate）at the foot of the Great Wall in Beijing’s northwestern Yanqing district. More than 110 countries and international organizations have confirmed their 【小题2】(participate) in the event, as well as more than 120 unofficial exhibitors. Exhibition curators(管理人)said 41 outdoor parks will open to 【小题3】public, including 34 independent 【小题4】 (one), and seven joint gardens.

So far, China’s 31 provincial-level regions, plus Hong Kong, Macao and Taiwan, have been divided into eight exhibition areas based【小题5】 their locations.

Environmental protection is the key element that provincial exhibits will stress. Channels have been built around the park 【小题6】(collect) rainwater.   Some special stones from around the country will also stand on a grand square 【小题7】 connects different gardens. The stone from Jiangxi province is blue and white, 【小题8】 (represent) the famous blue and white porcelain（瓷器） of the province’s Jingde town.

This is the second time China【小题9】 (host) a high-level horticulture expo. Kunming , Yunnan province , hosted the expo in 1999. Visitors can enjoy more than 2,500 【小题10】 (culture) activities throughout the expo.

In the past few years, the number of wild animals 【小题1】 (decrease). If nothing 【小题2】 (do), man will be punished by nature. 【小题3】 (lucky), people begin to take actions. Some nature reserves (保护区) 【小题4】 (build) now so that animals can live in peace. If everyone has the sense of protecting wildlife, it is certain that an atmosphere of wildlife protection will come into being.

On Oct 8th, 2019, Iceland honored the passing of Okjokull, the first of Iceland’s glaciers to disappear on account of climate change. In 1890, the glacier ice covered 16 square kilometers but in 2012, it 【小题1】 (measure) just 0.7 square kilometers. A monument is set up at the site of the former glacier, 【小题2】 bears the inscription (题词) A Letter to the Future, and is intended 【小题3】 (raise) awareness about the decline of glaciers and the effects of climate change.

The world is quickly realizing 【小题4】 is necessary to actively pull carbon dioxide out of the atmosphere to prevent the ill effects of climate change. Scientists and engineers have proposed a 【小题5】 (various) of techniques to deal with the change. 【小题6】 , most would be extremely expensive — without 【小题7】 (bring) any profits. Therefore, no one wants to foot the bill.

One method explored in the past decade might now be a step closer 【小题8】 becoming practical. The process 【小题9】 (involve) pumping CO₂ carried through the air down into methane hydrates (甲烷水合物) right under the seafloor, where the gas will be 【小题10】 (permanent) stored, or separated. The incoming CO₂ pushes out the methane, which will be piped to the surface and burned to provide electricity, to power the separation operation or to bring in money to pay for it.
