5、 The JUNE has UV sensors built into a fake jewel that connect wirelessly to a smartphone, where an app monitors UV【C15】_in real time, alerting when its time to get out of the sun. It also【C16】_your radiation exposure over time,【C17】_you can see how bad your summer has been for your skin, long term.
6、All of these products are designed to help wearers【C18】_their sun time.

10、 a role in learning to read and do math, but this ability is not just gene-driven,【C1】_schooling and help from parents are also vital【C2】_.Early mathematical ability and literacy are known to 【C3】_ in some families, but the genes【C4】_affect this have until now been【C5】_unknown.Scientists looked into
11、 a data pool called the Twins Early Development Study, which【C6】_12-year-olds from nearly 2,800 British families.The team compared twins and【C7】_children to see how they【C8】_in tests for maths and reading comprehension, and then matched the childrens genomes.Between 10 percent and half of the genes
12、involved in reading were also involved in math, they found, and tiny variants in these【C9】_genes influence skill level.【C10 】_its also clear how important our life experience is in making us better at one or the other. Its this complex【C11】_of nature and nurture as we grow up【C12 】_shapes who we are
13、Professor Robert Plomin said the study was the first to estimate the【C13】_from DNA alone on learning ability.But, he stressed, the genetic variants that were identified were not【C14 】_“literacy or numeracy“ genes.【C15 】_they formed part of a more complex mechanism in which many genes each 【C16】_ a
14、small, but combined, effect on learning ability.“Children differ 【C17】_ in how easy or difficult they find learning, and we need to recognize and【C18】_ these individual differences,“ said Plomin.“Heritability does not【C19】_ that anything is set in stoneit just means it may take more effort from pare
