一、阅读理解(本大题共10小题，共25.0分)

In 2012，Kim Stemple，a special-education teacher，found herself in a Boston hospital being treated for one of several diseases she had been diagnosed（诊断）with，including lupus and lymphoma． The normally confident Stemple was naturally getting very depressed． And then a friend gave her a medal．Before she got too sick to exercise，Stemple had been a marathon runner． The medal came from a racing partner who had just finished a half marathon in Las Vegas and hoped the souvenir would act as a kind of feeling pick-me-up．It worked like a charm-and then some．

After Stemple hung the medal near her hospital bed，other patients said they wanted medals too． That got Stemple thinking． "A medal is a simple way to give a positive message，"she told pilotonline．com． And so was born her charity，We Finish Together，which collects medals from strangers-runners，dancers，swimmers，singers，and even spelling bee winners-and donates them to all sorts of people in need．

Those who received the medals have included hospital patients，residents of homeless shelters，and veterans． Part of the process involves the donor writing a personalized note on the ribbon． "This gives them a connection to someone，"says Stemple． "If they receive a medal，they know someone cares．"

Can a simple medal really make a difference？Yes，says Joan Musarra，who suffers from pulmonary fibrosis． "I opened my package containing my new medal and the notes of positive，warm thoughts，I was overwhelmed，"she wrote to Stemple． "At that moment，I was sitting on my couch breathing through life-support machine because my lungs have been worsening so badly． It means so much to me to feel that I am not alone．"

1. Why did Kim Stemple start We Finish Together？ ______

A. To express a positive message to those in need．

B. To share medals collected from different people．

C. To show her sympathy to people in hospital．

D. To strengthen the relationship between the winners．

2. The underlined sentence in Paragraph 2 probably means that ______ ．

A. it was very effective

B. it was very charming

C. it added to her beauty

D. it attracted others immediately

3. What does Kim Stemple's story convey to the readers？ ______

A. Donating brings sunshine to both．

B. Sportsmanship can inspire people with hope．

C. People should help each other when in trouble．

D. The simple act of kindness really makes a person's day．

Chocolate could soon be a thing of the past， after scientists warned that the cacao plant， from which chocolate is made， could be extinct within 32 years．Over half of the world's chocolate comes from just two countries in West Africa-Cote d'Ivoire and Ghana-where the temperature， rain， and humidity provide the perfect conditions for cacao to grow． But the threat of rising temperatures over the next three decades caused by climate change， is expected to result in a loss of water from the ground， which scientists say could upset this balance．

According to the related data， a temperature rise of just 2.1℃ could spell an end for the chocolate industry worldwide by 2050． Farmers in the region are already considering moving cacao production areas thousands of feet uphill into mountainous area-much of which is currently preserved for wildlife． But a move of this scale could destroy ecosystems that are already under threat from illegal farming and deforestation．

Part of the problem， according to Doug Hawkins， is that cacao farming methods have not changed for hundreds of years． "Unlike other tree crops that have benefited from the development of modern， high yielding strains and crop management techniques to realize their genetic potential， more than 90% of the global cocoa crop is produced by small farms with unimproved planting material，" he said． "It means that we could be facing a chocolate decrease of 100，000 tons a year in the next few years．"

Now scientists at the University of California at Berkeley have teamed up with American candy company Mars to keep chocolate on the menu． Using the controversial（有争议的） gene-editing technology known as CRISPR they are trying to develop a type of the cacao plant capable of surviving in dryer， warmer climates． If the team's work on the cacao plant is successful， it could remove the need for farmers in West Africa to relocate to higher ground， and perhaps even allow cacao to be grown elsewhere in the world．

4. What do we know about chocolate from the text？ ______

A. Chocolate will disappear from the menu 30 years later．

B. Chocolate is mainly produced by African countries．

C. Chocolate will not be produced by 2050 because of climate change．

D. A new type of chocolate will be produced with the help of CRISPR．

5. What is the reason for the extinction of the cacao plant？ ______

A. The damaged ecosystem．

B. Water shortage caused by climate change．

C. The threat from illegal

farming．

D. The changeable farming method．

6. What is the writer's attitude to the application of CRISPR to planting cacao trees？ ______

A. Objective．

B. Unconcerned．

C. Supportive．

D. Negative．
