13．Around the world coral reefs（珊瑚礁） are facing threats（威胁） brought by climate change and great changes in sea temperatures．While ocean warming has been the primary focus for scientists and ocean policy managers，cold events can also whiten corals．A new study by scientists compared damaged to corals exposed to heat as well as cold stress．The results show that cool temperatures can cause more damage in the short term，but heat is more destructive（破坏性的） in the long run．
Climate change is widely known to produce warming conditions in the oceans，but extreme cold-water events have become more frequent and serious as well．In 2010，for example，coral reefs around the world faced one of the coldest winters and one of the hottest summers on record．
During a unique experiment，corals under cold temperatures suffered greater damage in just days compared with heat treated corals．Yet the researchers found that corals were eventually able to adjust to the cold conditions，make their health stable and continue to grow．However，over the long term corals subjected to heat suffered more greatly than those in cold，with evidence of severe whitening and growth stoppage，which leads to death．
The coral's ability to adjust to cool temperatures surprised the researchers，who say the study's results show the complexities（复杂性） of monitoring coral health in response to different environmental factors（因素）．
"Global warming is associated with increases but also decreases of temperatures，"said Deheyn，one of the researchers．"Not much has been known about the comparative effects of temperature decrease on corals．These results are important because they show that corals react differently to temperature differences，which is important for future management of coral reefs in the field of climate change．"

72．Which of the following is TRUE according to the passage？B
A．Corals are unable to adjust to temperature changes．
B．Heat and cold damage corals in their own ways．
C．Cold temperature causes greater damage to corals．

B.2010witnessed one of the greatest temperature differences on record
C．corals prefer warmer conditions to cold temperatures in the long run
D．global warming has nothing to do with the decrease of temperature
74．According to the research，D．
A．cold events help corals grow more quickly in a short time
B．corals show no response to hot temperatures in the first days
C．corals are whitened mainly because of warm temperatures
D．corals may continue to grow in cold events after a few days
75．Scientists reached the conclusion throughA．
A．scientific study B．news report C．great imagination D．natural conditions．

1．Do you have imagination？Do you like to solve problems？Can you？If so，you could be the next great inventor．"But I'm just a kid"，you might be!Don't worry about a little thing like age．For example，one famous inventor-Benjamin Franklin-got his start when he was only 12．At that young age，he created paddles for his hands to help him swim faster．Finally his creation led to what we know is called flippers!
So you don't have to be adult to be an inventor．One thing you do need，though，is something that kids have plenty of：curiosity and imagination．Kids are known for looking at things in new and unique ways．
So what should you do if you have what is a great idea for an invention？Talk to a friend or family member about it．Get input from others about your idea．Then ask them to help you create a working model-called a prototype（原型）of your idea．
Once you have a prototype，you can test it．Sometimes your idea turns out to be not as great as you thought．At other times，though，you realize it is a good idea and your prototype can help you figure out how to make it even better．
If your idea is really a good one，an adult can help you contact companies that might be interested in it．You will also want an adult's help to get a patent for your idea，so that it is protected and can't be stolen by someone else．If you need some inspiration，consider these kids and their inventions：
Jeanie Low invented the Kiddie Stool when she was just 11．It's a folding stool that fits under the kitchen sink．Kids can unfold it and use it to reach the sink all by themselves．
At the age of 15，Louis Braille invented the system named after him that allows the blind to read．
Chelsea Lanmon received a patent when she was just 8for the"pocket diaper（尿布）"，a new type of diaper that includes a pocket for holding baby wipes and powder．
