12.The world is being covered by plastic.In China,the amount of plastic waste rose into 14 million kilograms last year,but only about 9% was recycled.Over 1.32 million kilograms of plastic found its way into the world's oceans,which caused serious pollution.Luckily,researchers have found a special kind of bacteria which can help break down plastic recently. The bacteria are so small that we need a microscope (顯微鏡) to see them.They can "eat" plastic by changing its chemicals into something that will help them grow.The secret to this is enzymes (酶).Bacteria uses enzymes to cause chemical changes. In 2012,in the decaying (腐爛的) leaves,scientists discovered an enzyme called LCC that slowly broke down PET plastic.Most people know PET plastic.It is used in water and soda bottles.Most PET is thrown away,but even when it is recycled,it can't be made into new bottles.Compared with other 100,000 enzymes,it was the best at breaking down PET. To improve LCC,scientists studied the enzyme and the way it broke down the PET.By testing thousands of small changes to the enzyme,they found a new kind of LCC.It can be alive at higher temperatures,eat PET very quickly and make most PET plastic reusable.Scientists were satisfied with the result.When the environment was just right,the new LCC was able to break down 90% of the PET in just ten hours.The old enzyme took about 20 hours and only broke down half of the PET.
(1)How many plastic products are recycled in China last year?
A.About 1.32 million kilograms. B.About 14 million kilograms. C.About 1.26 million kilograms. (2)Which statement is TRUE about the bacteria?
A.Bacteria can be seen with our eyes directly. B.Bacteria can't be used to break down plastic. C.Enzymes help bacteria change chemicals in plastic. (3)From Paragraph 3,we can know
. A.most PET plastic could be made into new bottles again B.an enzyme called LCC was found in PET plastic in 2012 C.LCC was found the best at breaking down PET plastic (4)Compared with the old LCC,which is NOT the advantage of the new kind of LCC?

13.Height is just one of the thousands of features your genes (基因) decide.In fact,because you have two parents,your genes provide you a height that usually lands somewhere between the height of each parent.If both your parents are tall,then most probably you will be tall,too.If you have questions about how tall you're going to be,ask your doctor if he or she can help you find it out. But genes don't decide everything.For example,eating an unhealthy diet can keep you from growing to your full potential(潛力).Getting plenty of sleep and enough exercise will help you grow to the expected height. No doubt you're wondering how fast you should grow.It depends.There's no perfect or right answer,Generally speaking,kids grow about two inches(six centimeters) a year between age three and the time when they start puberty. Your doctor will know how your growth has been going over the years.Two centimeters here and two inches there are not nearly as important as the height you're at now,how you've been growing up to this point,and what other changes your body may be going through. Don't be nervous if you seem to have grown a lot in a very short time.Everyone has a growth spurt (高峰) during puberty.The age for starting puberty is about 10 for girls and about 11 for boys.But it can be earlier or later,between 7 and 13 for girls and 9 and 15 for boys. You'll usually begin to notice that you're growing faster about a year or so after your body starts to show the first changes of puberty.
