In recent years, climate change has had a great impact on the animals in water or on land. In 2013, a lot of people 【小题1】(shock) by a news photo of a dead polar bear 【小题2】Norway’s Arctic island of Svalbard. Due to the increase in temperature, the polar bear appeared 【小题3】(die) from lack of food.

According to climate 【小题4】(scientist), a key climate process called the “greenhouse effect” has two common meanings: the “natural” greenhouse effect and the “man-made” greenhouse effect. The former refers to the fact 【小题5】heat from the sun enters the atmosphere and warms Earth’s surface. Greenhouse gases in the atmosphere trap some of the heat, 【小题6】(keep) Earth’s climate warm and habitable. However, the latter has become a big problem. When people burn fossil fuels, more heat energy is trapped in the atmosphere and causes Earth’s surface temperature to rise 【小题7】(quick).

The evidence shows that the rise in temperature 【小题8】(lead) to an increase in extreme weather and natural disasters worldwide. It is warned that this warming trend will become 【小题9】(bad) if we do not take appropriate measures. The severe situation requires people all over the world to pay more attention to it, because this is 【小题10】most serious issue affecting all of us on this planet.

In order to make young people realize the 【小题1】 (important) of the Social Media Detox, we held 【小题2】 activity. Over 100 students had been persuaded 【小题3】 (stop) using social media for seven days, most of whom 【小题4】 (be) excited and nervous. It took Anna two days to be aware of the seriousness of 【小题5】 (check) phone. Doing the detox not only 【小题6】 (make)Devon realize the value of 【小题7】 (really) contact but also motivated Cindy to visit a different friend every day. An hour’s sport each day let George become healthier and healthier. It is a pity that Max threw in the towel 【小题8】 the first day. In a word, the Social Media Detox is successful, 【小题9】 helps teenagers step away from social media and communicate with each other 【小题10】 (well).

Nowadays, more and more parents pay great attention to their children. However, we find 【小题1】 common that parents and children lack communication.

More than one reason contributes【小题2】the problem.

To begin with,the reason why parents spend【小题3】(little) time with their children is that the heavier social pressure often makes children【小题4】 (ignore) by them. The second, although parents want to talk with their children, some of them don’t know much about the skills in communication or the necessary knowledge of education, which will have a big effect 【小题5】 communication. However, the most important reason may be the【小题6】(tradition) ideas of authority (权威) most parents have. Thus, when 【小题7】(face) the children,parents are not 【小题8】 (like) to communicate with them as friends.

To sum up, the solution concerning the problem【小题9】 (be) to diminish (减小) the gap between parents and children. Therefore, in order to make a better atmosphere 【小题10】 the children grow up, the parents should ensure the stability (稳定) of the family and act as good friends to the children.
