9.[1]If you don't have good nutrition(营养),you're missing a key weapon against colds.Basics include vegetables and nuts.The following are five surprising foods that can improve immunity(免疫力).
[2]Yogurt.Yogurt,a milk product,contains probiotics(益生菌).These probiotics change the immune system and help reduce the severity of colds.Choose the yogurt that contains live and active probiotics to make sure you're getting the benefits of the yogurt.
[3]Green tea.A cup of green tea can help cure a sore throat and lift spirits.Green tea can help prevent damage in the body.It may also fight against colds.
[4]Garlic(大蒜).Garlic has received widespread attention for its possibility of disease-prevention and immune-improving functions.In a study,researchers found that people who       regularly were two-thirds less likely to catch a cold.The best way to get garlic's benefits is eating it without cooking.
[5]Orange-fleshed (有橙色的果肉的) vegetables.Pumpkins,sweet potatoes,and other orange-fleshed vegetables are high in beta carotene (胡萝卜素),which the body uses to make Vitamin A.A diet low in beta carotene can reduce immunity,so eating vegetables is a great way to ensure your body has the nutrients it  needs.Vitamin A is also important in keeping skin healthy.
[6]Oysters(牡蛎).Oysters are definitely not the first thing that comes to mind when a cold or other illness attacks you,but they are a great source of zinc (Zn).Zinc is important in the development of white blood cells.It's best to get zinc from a balanced diet.In a addition to oysters,beef and chicken are good sources.

76.What does the text mainly talk about?( no more than 8words)
Five surprising foods that improve immunity

6.[1]How often does your child automatically pick up a book,a magazine,a newspaper,or other printed materials simply for the pleasure of reading?Experts have begun to realize that a young person's interest in independent reading seems to be important to long-term success.However,not all children will naturally love reading.That's where you as a parent      .
[2]First,understand that independent reading is not guided or shared reading.You may be present in the room with your son or daughter,but you will not be engaged in reading the book for your child.Instead,the child should pick up a book on his or her own,whether or not he or she can read all the words.
[3]Not only does this kind of independent reading increase a child's imagination,focus,comprehension and vocabulary,but it also allows him or her to build interest in a subject.For example,if he or she finds the Roman Empire fascinating,independently reading about that time period could broaden his or her understanding of society.
[4]One of the best ways to raise a youngster's interest in independent reading is to become an independent reader yourself.Turn off the TV and open the newspaper.Take time at the end of the day as a family to enjoy some free reading moments.The more you do it yourself,the more likely your child will be to accept it as a proper,regular thing to do.You can also begin building your child's personal"library".That way,he or she will have many choices of books to peruse during independent reading.
[5]Remember that reading achievement is linked to a love of independent reading.So the next time your child picks up a book,allow him or her to have some private moments.You'll never regret your decision to embrace independent reading.

76.Fill in the blank in Paragraph 1with proper words.( no more than 6words)
should do your part
77.What are the benefits of independent reading?( no more than 20words)
It increases a child's imagination,focus,comprehension and vocabulary,and allows the child to build interest in a subject.
78.What do the underlined words"that time period"in Paragraph 3probably refer to?( no more than 6words)
Time of the Roman Empire.
79.What is the main idea of Paragraph 4?(no more than 10words)
Ways to increase children's interest in independent reading.
80.What should a parent do when his/her child picks up a book on his/her own?(no more than 15words)
Allow the child to have some private moments and read alone..

7.My name is Clara.I still remember that chilly December day,sitting in science class.I had finished a worksheet early and picked up a TIME for Kids magazine.A piece of news caught my eye:NASA (美国宇航局) was holding an essay contest to name its Mars rover (火星探测器).Before I even knew anything else about it,a single word flooded my 11-year-old mind,Curiosity.
I couldn't wait for the bell to ring so I could get started on my essay.That afternoon,I raced home,sat down at the computer,and typed until my fingers ached."Curiosity is an everlasting flame that burns in everyone's mind…"
Five months later,my mom received a phone call,and immediately,a wide smile spread across her face.
On August 5,2012,at 10:31pm,the rover named Curiosity touched down safely on the surface of Mars,and I was honored to have a front-row seat in NASA.
Curiosity is such an important part of who I am.I have always been fascinated by the stars,the planets,the sky and the universe.I remember as a little girl,my grandmother and I would sit together in the backyard for hours.She would tell me stories and point out the stars.Grandma lived in China,thousands of miles away from my home in Kansas,but the stars kept us together even when we were apart.They were always there,yet there was so much I didn't know about them.That's what I love so much about space.
People often ask me why we go to faraway places like Mars.My answer is simple because we're curious.We human beings do not just hole up in one place.We are constantly wondering and trying to find out what's over the hill and beyond the horizon.
66.How did the author get the news about the essay contest?(within 7words)By reading a TIME for Kids magazine./From a TIME for Kids magazine.
67.In which year was the author born according to the passage?(within 2words)In 2000.
68.Why did author have a front-row seat in NASA?(within 10words)Because she won the essay contest held by NASA./Because she named the Mars rover"Curiosity".
69.What does the author remember about the time spent with Grandma?(within 15words)She sat together with grandma listening to her stories about stars./Her grandma told her stories about stars./They sat together talking about stars.
