One day，you open the fridge and find some moldy（发霉的）food．But before you can throw it away， your mother stops you． She doesn't want to waste food．She cuts of the moldy part and eats the rest．Is it safe to do this？
Mold（霉菌）can grow on almost all kinds of food．Mold is usually green， white， black or gray．Mold makes food soft and changes its color．Moldy food tastes quite bad﹣and it's not safe to eat．
If you find mold in soft food， just throw it away． Bread，tomatoes and hot dogs are soft food．This kind of food allows mold to easily grow below its surface．
But it's easy to remove mold from hard food．The mold can't grow very deeply inside this kind of food． According to the BBC， you should cut about 2．5cm around and below the mold and remove it．It's OK to cut the moldy parts out of hard food and eat the rest．But if the food is completely covered with mold， you should still throw it away．
Most kinds of mold are bad for us．But some kinds of mold can be used to make food． For example，penicillium（青霉菌）can be used to make many types of cheeses，such as blue cheese．These cheeses are safe to eat and they' re quite delicious as well．
（1）What color is mold？
（2）How does moldy food taste？
（3）How should you deal with the soft food when you find mold in it？
（4）Is it easy or difficult to remove mold from hard food？
（5）What can some kinds of mold be used to do？
The famous scientist and thinker， Charles Darwin， was born on February 12，1809． His family lived not far from the River Severn， England．
Darwin's father was a well ﹣known doctor and the son of a still greater doctor and scientist．Darwin's father hoped that his son would also become a doctor．
As a boy， Darwin liked to go for walks in the fields and forests． He watched nature， and compared what he saw with everything he had read in science books． He also liked collecting very much． He collected many things， birds， eggs， stones and leaves． His father did not like this， as Darwin was not studying very well at school．
At the age of sixteen， Darwin was sent to Edinburgh Univensity to study in order that he could become a doctor． But he was interested in the history of nature．
Then he was sent to study in Cambridge Univesiy．There he studied until 1831．
Some time later he heard that the ship Beagle was going on a trip to South America and needed a scientist．His professor advised him to go．He said the trip would be just for Darwin．So when the ship left England in December 1831． Darwin was on it． The research lasted almost five years． The Beagle studied the waters in the sea near South America． It also visited New Zealand， Australia and islands in the Pacific． Darwin saw many new plants and animals． He collected all kinds of plants．
In 1842 Darwin went to live in Kent， where he continued his studies of changes in nature． Darwin understood that plants and animals are not always the same， and that they really change．
By 1859 Darwin had finished his famous book"The origin of Species"（《物种起源》）．It made a great hit in the world of science．He was opposedby the church and even by some scientists．But later，more and more scientists agreed with him．

Reading is getting more popular among young Chinese． A new survey says that 85% of young people in China read at least 1 book last year． The number of young people who are reading has been rising in recent years， especially for teenagers， who read an average（平均） of 11.5 books．
The data（数据） shows that teenagers spend much more time reading from school textbooks to some other reading materials， such as novels， e﹣books， magazines and so on． But younger children （ages 2﹣8）are mainly reading for fun． Compared with the past， the time teenagers spend on pleasure reading has dropped．
When it comes to technology and reading， the surver suggests little．It does point out that many parents control the time of electronic reading， mainly because of worring about increased screen time． However， most Chinese parents are helping theie children to develop a reading habit． They are served as examples for their children． More than 70% of Chinese parents spend at least 20 minutes a day reading to their children aged 0 to 8 years old， and visit bookstores with them an average of three times a year． Data shows that kids and teens who do a lot of reading， compared to those who don't like reading， have more books in the home， and more books brought for them． Their parents read more often， and would like to spare time to read with them．
When was the last time you read a book？ If you're one of the countless people who don't develop a habit of reading， you might be missing out． Everything you read fill your head with new bits of information， and you never know then it might be useful． The more knowledge you have， the better equipped you are to deal with any shallenge you'll face． Remember that although you might lose something else， knowledge can never be taken away from you．

Many of us wish we would have longer weekend， but for about 18，000 students in Colorado， that wish is coming true． A school district outside Denver has decided to shorten its week to four days﹣from Tuesday to Friday， and the first school year on this new timetable just started，CBS Denver reports． It began on Tuesday， August 14， because the day students get off is everyone's least favorite： Monday．
Although this may sound like a dream come true， it means students will have to sit though longer school days to work more for the hours they've lost， according to The Denver Post． So the timetable seems more crowded than ever．
The decision wasn't made just to give students more days off， though：it had practical purpose． The district says that it will save ＄ 1 million by not having buses on Mondays and spending less on things like electricity and water． That means a lot to the school． However， there are different voice． Parents may pick upsome the cost of this change， though， since many will now need to stay home with their kids． If they go to work， they have to find people to take care of their children．
This isn't the first district in the state to introduce a four﹣day week：55% of the state's schools do this， but most of them are in the countryside， according to The Denver Post． Several school in Oklahoma made the some move earlier this year， and some them told CBS News Reports that more teachers wanted to teach there after the change． Most of these teachers have a lot of teaching experience． About 560 districts in timetable influence students's performance．
