When you eat a traditional ice cream in summer, you need to finish it quickly to make sure the treat doesn’t end up melting down your hand. Reach for an ice cream sandwich instead, and you’ll, find the ice cream stays solid longer magically. An ice cream that refuses to melt seems unnatural, but you might be surprised by what’s really behind its practically heatproof (耐热的) abilities.
Ice cream without a proper container in the fridge would lead to ice blocks because of its water content. Most ice cream contains some elements called emulsifiers (乳化剂) that can keep water to fat to prevent ice blocks. They go a step further by helping to keep ice cream consistent, even under the hot sun. On an element list, you might find different chemicals with the same goal: to hold water in so the ice cream doesn’t melt quickly. Ice cream sandwiches generally contain more of those chemicals including emulsifiers than hand-made ones.
If you’re worried about some additives (添加剂) in ice cream sandwiches f which might belong in a lab rather than your kitchen, then you’d better be at ease. Even completely natural elements, which come from beans, might make you stop eating if you’ve heard about their misuse in weight-loss efforts.
Of course, the Food and Drug Administration (FDA) takes any of the side effects of those chemicals into account, and the amount you’d find in an ice cream sandwich isn’t enough to cause health problems. While you meet someone willing to share his ice cream sandwiches with your kid, there’s no reason to fear your kid’s health safety. A slow melt rate method causes you less worry.

Que Liu and his wife Si En spend their mornings picking Pu’er leaves in a forest not far from their village in the highlands of southwest China.
Pu’er is a kind of tea that is famous for its complex taste. Tea lovers say its taste changes with each following steeping (续泡). But the crop this year has been small at Nannuoshan, one of the six major Pu’er mountains in Yunnan Province. The hottest weather and lowest rainfall totals in years have reduced production. “Drought has cut production by about half this spring,” said Zi Sai, the son of Que Liu and Si En.
Local officials blame climate change for an increase in drought-like conditions in recent years. The dry weather has worsened over the past 20 years, with this year’s drought breaking some records. “The entire rainfall pattern has changed due to global warming,” said Xiao Chan, head of weather services at China’s National Climate Center in Beijing.
Pu’er trees grow in the cloud-covered forests of Yunnan. The trees require no fertilizers or pesticides (农药), unlike the tea trees grown on large farms elsewhere. The adult plant normally reaches a height of four meters. Spring produces the highest-quality leaves from the trees. The summer harvest, with a higher percentage of water, is considered to be lower in quality. Summer leaves are sold for mass consumption.
The drought conditions hurt the economy of the 32 villages of Nannuoshan. “My family depends wholly on Pu’er tea for survival, earning about 200,000 yuan a year,” said Zi Sai’s uncle, Si Da, who is 44. “That represents just over $28,000. This year, our income has been cut by tens of thousands of yuan.”
While one ancient tree, said to date from 800 years ago, survived the drought, other younger trees did not. “If these kinds of trees survive, they may need three to five years for a full recovery.” Si Da added. “These trees are quite pitiful. They should have been protected like children.”
1.How is the climate in the Pu’er tea planting areas in recent years?
A.It is too wet. B.It is much colder.
C.It is changing regularly, D.It is becoming much drier.
2.What’s the advantage of Pu’er trees compared with the tea trees planted on other big farms?
A.They are short and small. B.They are pollution-free.
C.They grow on large farms. D.They are picked at all seasons.
3.What does Si Da think of the younger tea trees?
A.They were easy to live on.
B.They should have been taken good care of.
C.They took only a short time to fully recover.
D.They had better be cut down to earn money.
4.What is the main idea of the text?
A.The extreme weather ruins tea farms.
B.Famous tea in China might disappear.
C.Few tea trees survive natural disasters.
D.Drought hurts Pu’er tea crops in China.
In the year 2017, the world lost many great musicians. Their deaths were felt over the world and country music star Keith Lionel Urban honored these musicians in a very special way. During a New Year’s Eve concert, Keith talked about all the greats that passed away and how some of them were music and life coaches or examples to him. That was when Keith decided to put together a mixture of songs from all of these artists.
At the concert, pictures of some of the most eminent people in the music industry appeared across the screen. As their pictures appeared, Keith sang the songs that the artists were best-known for. Each performance was truly moving, and the audience loved it. Instead of thinking it was a sad moment, everyone was able to think about how much joy these artists brought to the music industry.
Keith sang a few lines from songs by Chris Cornell, Gregg Allman, Chuck Berry, Don Williams, Glen Campbell and Troy Gentry. The audience cheered aloud whenever he changed from one song to another.

阅读下面短文，根据所给情节进行续写，使之构成一个完整的故事。
David and Roy decided to go for a bicycle ride with three other students: Robert, Helen and Betty. But Robert’s father couldn’t afford to buy a bike for him. So they were going to borrow one for him.
The students had planned to meet at 8 o’clock. But Robert, Helen and Betty were half an hour late, for they had to come a long way since they found the bridge over the stream had been washed away.
When they told the bad news to David and Roy, David said nothing and kept silent for a moment. After a while, an idea came into his mind. “Do you think we could rebuild it?”
All of them agreed and started to consider this seriously. They decided to rebuild the bridge before they went for the bicycle ride. Betty said she could ask her brother to make a plan for them.
The biggest problem was to get enough wood. The next day they visited nearly every house in the village. Mr. Robinson agreed to supply the wood so long as they did the work. Several people promised to give money if they could build a new bridge because it was a short cut for them.
The students worked for nearly a week under Mr. Robinson’s guidance. At the end of a
week of hard work, the bridge was completed. They all agreed to ask Mr. Robinson to officially open the bridge. “He has helped us most,” David said.
“And tomorrow morning we can go around to all the houses,” added Roy, “and tell the people that the bridge will be officially opened at six o’clock. Then we can remind them about their promises about money,” Roy added.
“But we don’t really want that, do we?” said Robert.
“Yes,” said Helen. “We need it and I think we should collect it.” She glanced quickly at the others, who nodded.
The next day, the students visited all the houses again. They were surprised when they saw how pleased the people were with them. By two o’clock they had collected over a hundred dollars. By five o’clock, unknown to Robert, they had spent it.
