Most people suffer from 【小题1】 is known as “Just-me-ism” sometimes. As a result, they think their actions, for example, leaving the tap 【小题2】(run) while they brush their teeth, leaving a light burning when they go out or dropping a piece of litter and not being bothered 【小题3】(pick) it up, won’t be harmful 【小题4】 the environment or their community. But, in fact, they will and they could matter. Roots & Shoots was established in the early 1990s by Dr. Jane Goodall, who’s well-known 【小题5】 an expert on wild chimpanzees. Its purpose is 【小题6】(educate) young people to build a future that is secure and live together in peace 【小题7】nature. The idea is that if you educate enough individuals, they can change the world and make it a 【小题8】(good) place for people, animals and the environment because as Dr. Jane Goodall says: “It is by 【小题9】(act) together, in this exciting way, 【小题10】we can involve thousands-millions-of people, and this is what is going to change the world.”

There is little doubt that Earth is getting warmer and warmer. In 2013, many people 【小题1】(shock) by a news photo of a dead polar bear which appeared to have starved to death. Experts claimed that low sea-ice levels   【小题2】(cause) by climate change meant that the bear could not hunt seals as before, so it had to travel greater distances 【小题3】(find) food. Then what is causing the increase in the global average surface temperature? Climate scientists often mention a key climate process called the “greenhouse effect”, 【小题4】has two common meanings: the “natural” greenhouse effect and the “man-made” greenhouse effect. The “man-made” greenhouse effect has now become 【小题5】big problem. There is strong and comprehensive evidence 【小题6】the rise in temperature has led to an increase in extreme weather and natural disasters worldwide. Actually, news reports are 【小题7】(frequent) broadcast about extreme rainstorms and heatwaves 【小题8】(cause) deaths and economic losses. Continued greenhouse gas emissions will result in further warming and long-lasting changes to the global climate. This requires the attention of people all over the world. We as individuals can also reduce our “carbon footprint” by 【小题9】(restrict) the amount of carbon dioxide our lifestyles produce. It is our responsibility 【小题10】(seize) every opportunity to educate everyone about global warming.

Five tiny Pacific islands have disappeared due to rising seas and erosion(冲蚀), Australian researchers say.

There were no 【小题1】(human) who lived on the five missing islands, part of the Solomon Archipelago. The islands were 【小题2】(occasional) used by fishermen. But six other islands 【小题3】(believe) to have seen lots of land turn into sea, destroying entire villages. One of the six islands is Nuatambu Island, 【小题4】 is home to 25 families.

According to the researchers, the Solomon Archipelago 【小题5】(see) sea levels rise as much as 10 mm every year in the past twenty years. However, the report stresses that the current situation doesn’t result 【小题6】 rising sea levels alone. Erosion of the shoreline makes the situation worse. Extreme events and improper 【小题7】(develop) are two major factors of 【小题8】(contribute) to the erosion.

The Solomon Islands, 【小题9】(make) up of hundreds of islands and with a population of about 640,000, lie about 1,000 miles northeast of Australia. Some communities have already adapted to the changed conditions. Several Nuatambu islanders have moved to 【小题10】 higher neighboring volcanic island.
