2．Children with autism （自闭症） have difficulty with social skills and communication．They often behave in limited and repeated ways and have what seem like unusual strong interests．
Autism is more common in boys than girls．What causes it is not clear．Scientists are studying genes and possible environmental influences．
Doctors usually cannot confirm a diagnosis of autism until a child is about three years old．Rebecca Landa is a researcher at the Kennedy Krieger Institute and Johns Hopkins University School of Medicine in Maryland．Professor Landa wanted to find out what differences in development might be seen earlier．She led a new study that observed 235babies between six and 36months of age．
"At six months of age，the signs of some risk for developing communication and social delays，including autism，include motor delays，like when you lay your baby on their back and you pull them by the arms gently into a seated position，the baby's head may nod back behind the shoulders，like poor head control．So that does not mean that the baby is going to have autism，but it does mean the baby needs to have some exercises to strengthen their body．And when they strengthen their body，they are better able to play with toys and engage with people，which then goes on to help them have better outcomes．"
By the time a baby is one year old，signs of possible autism include difficulty in using words and not looking eye-to-eye or reaching out to other people．By 14months，the baby might smile less and use language less．However，Professor Landa says these signs can be so small that they might be missed during a short health exam．
"It's important for parents to stay tuned in to their children's development，and if a parent is concerned about a child's development，for professionals to listen to them．"
The earlier parents notice delays，she says，the sooner they can begin doing simple things that may help improve their child's development，such as talking to the child about what they are doing，commenting when the child shows them something，and playing simple games that keep the child's attention．

1．Not all vegetables need lots of sunshine．Mark Hoffman and his wife，Guia，own a bed-and-breakfast guesthouse in rural Kempton，Illinois．They often serve their guests produce fresh from the garden．
The Hoffmans have been growing food and flowers for twenty-five years．For almost ten of those years，Mr．Hoffman has been experimenting and working with shade plantings．He says visitors to his website-greenhousebed．com-often ask how to plant in shade spaces．He said，"The bottom line here is that most plants will produce more in full sun．But if you do not have full sun，there are other options．"
For example，he grows tomatoes near oak trees．Oak trees can produce a lot of shade．But Mr．Hoffman says his tomato plants grow as long as they get five hours a day of direct sunshine，especially morning sun．Not only does this go against the traditional advice that tomatoes need six，eight，even twelve hours a day of full sun，it also shows how plants and trees roots can share nutrients and water．Mr．Hoffman also planted asparagus（芦笋） around a tree at its drip line，the area below the outer limit of the branches．So when it rains，all the rain drips down right on the asparagus．
The Hoffmans'website includes a list of vegetables，flowers and herbs that have produced acceptably for them in partial shade．Mr．Hoffman says plants with wider leaves seem to do better in shady environments．He also found that his potatoes did better in partial shade than in full sun．
Moving them out of the sun helped control an insect problem with leaf hoppers．Mr．Hoffman does not use pesticides （农药）．Instead，he planted the potatoes at the drip line，especially on the east side of the tree．The potatoes get morning sun，but they are shaded during the hottest part of the day．Leaf hoppers dislike shade，and the hottest part of the day is when they do the worst of their damage．
Time of day，brightness of the sun，shadows from trees，walls and buildings，these all influence how much sunlight falls or does not fall on plants．And extension agent Curtis Swift at Colorado State University says people interested in shade planting should also remember something else．The term"shade"can describe different amounts of darkness．He says it can even mean different things in different parts of the world．

Dear Editor，
I'm writing to tell you about a food poisoning accident．Several day ago，my neighbors ate a bag of food buying from the market．After the meal，they had stomachaches and their faces turn pale．Fortunately，one of their friends found the accident and immediately called on an ambulance，which carried them quickly to a hospital．After several hours'treatment they finally escaped death．
As some illegal businessmen are only interesting in making profits to become rich quickly，we seldom care about the necessary safety measures． Nor do they care about which happens to consumers． They shall be charged with law．Meanwhile，I do hope whole society can realize the important of food safety and taking action together to make sure food is safe．
