When was the last time your family sat down together to have a dinner?
The speed at which we live today no longer allows for slow eating habits. Most people work long hours. There is lots of fast food and eating out is now on the increase. Often, food is eaten in front of the television in silence, or a child eats alone in front of the computer.
When I was a child, every evening around the same time, one of the children would be asked to set the table, and then we'd go and wash our hands: before the meal. This was the time of day when we would talk about our day at school. But now things have changed a lot.
A family environment plays an important role for children in learning to communicate with others and understanding table manners, such as waiting for others to finish before leaving the table and not speaking with a mouth full of food. Parents’ likes and dislikes of a certain food will also influence a child's own likes and dislikes. Studies have shown that children who often eat with their families have better results at school than children who eat with their families less than twice a week.
Regular meal times give children the chance to discuss their problems with family members. They can also learn to respect others around the table. Talking to your children over dinner is the best way of having their-trust. Children learn good eating habits from their parents at a very young age. Family meals are important. Prepare them for your children.Some families eat less together because __________.
| A．most children live in a school |

Every year in late spring at Wild Friends, the wildlife health center, workers receive baby animals, including songbirds and rabbits. This is the busiest time when workers care for and raise all the little ones before sending them back into the wild.
There are many reasons for these little animals' coming to the center. First of all, street cats or dogs catch, injure or take away little birds from their nests. Sometimes people catch baby animals and keep them at home, giving them food that they are not used to. It would make them sick. Most people don't realize that it's against law to get live animals out of their nests.
As for songbirds, people often find them on the ground in their yards, thinking they have no other choice but to leave them on the ground to die. This is because many people wrongly believe that once a bird is touched by a person, its mother will not accept this child bird. But that's not true.
If a little bird falls out of the nest, you should check whether it is injured. If not, you should put the bird back in the nest. If the bird is injured, call your local wildlife center quickly.
As for the progress of protecting wild animals, people at Wild Friends devote all their energy to this work. Over the last weeks, they have been able to send many of the birds and rabbits that came here earlier this spring back to nature.Which is the busiest season for workers at Wild Friends?
| A．Spring | B．Summer. | C．Autumn. | D．Winter. |
Which of the following will probably injure young birds?

| A．wait for its mother | B．help it go back home |
| C．touch it with your hands | D．call workers at Wild Friends |
Life on Mars could become a reality and it could happen in your lifetime.
A welcoming planet
Scientists say Earth’s neighbor Mars, a bright red planet about half Earth’s size, is the most likely to support human life. Mars even has frozen water on its surface.
Since the late 1990s, NASA has been exploring Mars using remote-controlled vehicles（装置）. Most recently Curiosity, a car-size vehicle, traveled through space on an unpiloted spacecraft(航天器) and landed on Mars in August 2012. Directed by NASA scientists , the vehicles move on the surface, taking pictures , collecting and analyzing soil, and looking for signs of life.
But what about human explorers? Plans are already in the works to send astronauts to Mars as soon as the mid-2030s.
_____________________________________
But before you start packing your bags, let’s consider the challenges. For starters, Mars is far away. Just getting there could take up to 10 months.
Scientists already know that time away from Earth’s gravity harms the human body. Bones and muscles get weaker. The body produces less blood. What damage would months and months of living in space do?
And then there is the matter of water, oxygen, food and fuel. Scientists will have to find solutions to these problems, or the first humans on Mars won’t survive very long in their new home.
Tiny Dangers
There’s another tinier risk. It’s so tiny that you can’t even see it: germs.
Some scientists believe that our germs could pollute the whole planet of Mars. Potentially killing Martian life before we have the chance to discover it. Worse, there is a small but terrifying chance that any microscopic life already there might be harmful to us .
Worse still, if any of those Martian germs(火星细菌) were brought back to Earth, the result could be disastrous. Animals, plants, and people could be wiped out.
Worth the $$$?
A more practical concern is the cost. The price could approach $ 1 trillion(万亿). How can we justify spending that much when so many problems—poverty, disease—could use the cash here on Earth?Which of the following is TRUE according to the “A welcoming planet” part?
| A．Mars is a little bigger than Earth. |
| B．There are flowing rivers on Mars. |
| C．People haven’t been to Mars so far. |
| D．Scientists have discovered signs of life on Mars. |
Which of the following can best fill in the blank in the passage?
| A．Living in space. | B．Limited resources. |
| C．Extreme conditions. | D．Interesting challenges. |
By “Tiny dangers” the author means ________________.
| A．there is no serious danger |
| B．people won’t be in any danger |
| C．it’s difficult for people to realize the danger |
| D．the danger may be caused by very small things |
Which may cause the biggest danger?
| A．Martian germs may be different from those on Earth. |
| B．Martian germs may be brought back to Earth. |
| C．People may carry germs to Mars. |
| D．There may be germs on Mars. |

President Barack Obama rode a bicycle at the White House Science Fair on April 22. But it wasn’t an ordinary bike. As he pedaled, the President stayed in place, while the energy from his pedaling powered a water filtration (过滤) system. He was testing an invention created by a team of 14 students from Northeast High School, in Oakland Park, Florida.
Payton Karr, 16, and Kiona Elliot, 18, attended the fair as representatives of the project.“We were hoping President Obama would ride the bike, but we didn’t actually expect him to,” Payton told TFK. “ It really meant a lot.” Kiona agreed. “It was pretty awesome to see the invention, which was invented by a group of 14 high school students and one teacher, along with the help of community members, got the interest of the leader of our nation,” she said.
The project was an idea that came about after one of the Northeast students, Kalie Hoke, visited Haiti after the terrible 2010 earthquake and saw how difficult it was to find clean water. The students invented a portable(便携的), bicycle-powered emergency water filtration system, which can provide 20-30 people with drinking water in a 15-hour period. The teens hope their invention will one day be used by relief organizations like the Red Cross. “ They can take it to places after natural disasters so that water can be clean for the people there,” said Payton.
Payton and Kiona were among the 100 students from more than 40 states invited to the third annual White House Science Fair, in Washington, D.C., which is also attended by leaders in science and education. President Obama started the event in 2010 to stimulate students interested in STEM (Science, Technology, Engineering, Maths).“Well, if you’re a young person and you produce the best experiment or design, you ought to be recognized for that achievement,” Obama said when he first announced the fair.
President Obama praised the projects during a speech to attendees after the fair. “The science fair projects of today could become the products and businesses of tomorrow,” he said. “If you’re inventing things in the third grade, what are you going to do by the time you get to college?”What is special about the bicycle President Obama rode?
| A．It can move very fast. |
| B．It is extremely beautiful. |
| C．It is used to make water clean. |
| D．It is made of eco-friendly materials. |
The representatives of the bicycle-powered water filtration system_________.
