5 . 根据短文内容，从短文后的七个选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。

Now there is an increasing number of inactive people, namely the “mouse potato”. A mouse potato is someone who sits in front of his or her computer all day and eats junk food instead of regular meals. Why are we becoming potatoes and what can we do to avoid it?

One reason behind it is our modern way of life. We don’t have as much time to prepare and eat food as we used to.     1    Not all of these are bad for us, of course, but they make it more difficult for us to control what we eat.

If we want to be healthy, we should make good choices about what we eat.   It is not necessary to become a vegetarian, but we must make sure that our diet is varied and balanced. A healthy diet should give us the calories we need but not contain too much fat and sugar. The number of calories our body needs depends on what our body type is, how much we weigh and how active we are.

Teenagers need about 2,500 calories a day.    2    Getting the calories we need is not enough. If we want to be healthy, we must make sure that we get the calories in the best way possible. The best source for calories is carbohydrates, which are found in gains, vegetables and fruit. Our bodies store carbohydrates in our muscles so that we can get energy when we need it.

Junk food has a lot of calories but few nutrients, vitamins and minerals, Some food does have nutrients, for example pizza, but because it contains too many calories, it is still called junk food. A healthy diet should include a variety of food, most of which should be rich in nutrients.     3     Those of us who love French fries, sweets, ice cream and cheeseburgers can still enjoy an unhealthy bite every now and then. All we have to do is to be careful how often and how much we eat of it.

If we make the right choices about what we eat, we will be healthier and have more energy to enjoy the good things in life.     4    And remember, it is better to eat a potato than to be one.

A．Choosing what to eat is no longer as easy as it once was.

B．That does not mean that we are never allowed to eat junk food.

C．A balanced diet combined with exercise is the recipe for a healthy life.

D．Girls usually need a bit less and people who play sports may need more.

E．A large breakfast, one containing about 700 calories, will help lose weight.

F．Fast food restaurants are everywhere and supermarket shelves are filled with ready-made pre-prepared dishes.

Dear headmaster, As president of Sullivan Junior High School’s student council, I have been chosen to write to you on behalf of the eighth grade class. We would like to propose an eighth grade promotion trip to Sea World in San Diego, California. We chose Sea World for several reasons. In science class, we have been studying oceans and the marine life. Going to Sea World would provide us with the opportunity to visit these creatures and to better understand their habitats. This could be a once in a lifetime experience for those of us who have never been outside Arizona. We will have lots of fun and learn at the same time. The close location of San Diego was also a factor in planning this trip. San Diego can be reached by bus in about six hours. If the buses leave Sullivan after school on Friday afternoon, we should arrive in California in time to have a late dinner and get settled into our hotel rooms before midnight.

You may be asking yourself. “How will this trip be financed?” We are suggesting that the school host an “Oceans of Fun” night for family, friends, and community members for a small fee. The activities would be organized and supervised by eighth grade students. Some of our ideas for the night include a Surfer’s Snack Shop with homemade treats for sale, Pirate Pete’s Treasure hunt, and a short production of “A Whale of a Tale.” This would the best chance to show our ocean animal reports. Many of the eighth grade students have gone to school together since kindergarten. We believe that this trip would be a fantastic way to celebrate friendships. This trip may also be one of the last times we see our friends because students from Sullivan Junior High School attend four different high schools. We invite you to our next student council meeting on December 7, 2013, to discuss your thoughts and work out any concerns you still may have. Thank you for taking the time to consider our request for an eighth-grade promotion trip. Sincerely, Julie Martino

7 . To Their Own Beat

When Los Lobos perform in concert today, audiences in the thousands cheer them on. It’s hard to believe that the group started out as just another garage band playing popular rock-and-roll tunes from the radio, In 1974 four high school friends from East Los Angeles formed Los Lobos ( Spanish for “The Wolves” ) .

Like many garage bands, these friends might have simply gone their separate ways after high school. But the members of Los Lobos wanted to keep making music together. They decided to change their musical style and began focusing on traditional Mexican music that showed their tradition.

“We pulled out all those records we used to beg our parents not to play around our friends and found an incredible wealth of music,” says Perez. “These guys (on the records) were doing amazing things with their instruments, and we started trying to pick up on it. ”

The group put aside its electric guitars for the acoustic ones used in traditional Mexican music. For several years Los Lobos played at weddings or parties—any event that needed live music. They also landed a regular engagement (合同)   at a Mexican restaurant.

By 1978 Los Lobos had made enough money to record their first album   (唱片) , and they sold copies of it wherever they performed. They also returned to their electric guitars to get closer to a Tex-Mex sound, which is a mixture of traditional Mexican music, rock and roll, country music, and the blues. This new, louder sound produced one unexpected result: the group was fired from the restaurant.

But it didn’t matter that Los Lobos had lost their one steady job, because they had found a position that no other group took up. They had combined electric and acoustic instruments and blended (混合) musical styles in their own way. Steve Berlin joined the band in 1983 as the saxophone and keyboard player, adding to the band’s unusual sound.

“We didn’t so much want to recycle the music we’d grown up with as much as find the common links between it and all the other styles and sounds that were all around us,” Perez explains.   “It became a mission ...   bringing music together to bring people together. ”

In the 1980s Los Lobos gained the attention of several record companies. They were hired to perform on the soundtrack to the film La Bamba, which earned them a Golden Eagle Award. They have since earned many awards, including two Grammys and an MTV Video Music Award. Their many records have been very successful, and they have toured the world.

Even after 30 years of making music together, Los Lobos continues to experiment with their sound. They never moved far away from their Mexican roots, however.   They still include traditional music in their live performances, sharing their history—and their culture—with their fans.

9 . In comparison to many closely-related species, the human child takes a long time to grow up and requires a high degree of parental investment(亲情投资). Human children need more time to reach maturity(成熟)than other closely-related species.

A new study finds that one reason is the large amount of energy that the brain requires as it grows.

Christopher Kuzawa, first author of the study, explained: “Our findings suggest that our bodies can’t afford to grow faster during the toddler(幼童)and childhood years because a huge quantity of resources is required to fuel developing the human brain. As humans we have so much to learn, and that learning requires a complex and energy-hungry brain.”

Data from the study shows that at the moment when children’s bodies are growing the least-on average, at four years old-their brains are using the highest percentage of glucose(葡萄糖). That means that 40% of the child’s total energy expenditure is being used by its brain.

The findings support the theory that children take so long to mature because of the energy-intensive task of growing a massively over-sized brain in comparison to the brain-to-body weight ratio of other species.

Kuzawa continued: “After a certain age it becomes difficult to guess a toddler or young child’s age by their size. Instead you have to listen to their speech and watch their behavior. Our study suggests that this is no accident.”

Body growth nearly stops at the ages when brain development is happening at a lightning pace, because the brain is using up the available resources.”

“The mid-childhood peak in brain costs has to do with the fact that there are a huge number of synapses(神经元突触), connections in the brain, at this age, when we learn so many of the things we need to know to be successful humans.”

1. Why does it take people so long to grow up?

A．They need to store energy to grow later.

3. What is the main idea of the passage?

A．Why toddlers and children need plenty of resources.

B．The reason why it takes human infants a long time to grow up.

C．The reason why human infants are similar to other animals.

D．Why the brains of people need a large amount of energy.

4. The underlined word “this” refers to________.

A．age	B．their size
C．listen to their speech	D．guess their age by listening and watching

10 . Dog walkers should show consideration, not just for the dog in their home or car, but also for their environment. Doing so will help keep the local area clean and pleasant, especially for people out walking their dog or taking children to the park.

A considerate dog walker will take steps to prevent their pets from producing waste wherever they want to. Dog waste is particularly unpleasant and should be avoided at all costs. Not only is it nasty to walk in a dirty area, but it is also a serious health risk. Dog fouling ( 污垢) is a criminal offence in the UK and carries a maximum fined ￡1,000 if the case goes to court (法庭). Dog walkers should always be prepared to pick up after their dog by carrying dog waste bags or even plastic carrier bags that can be used. Do not run the risk of allowing your dog to make a public area dirty by always having a steady supply of bags with you during dog walks. Carrying a single bag during a walk is not always enough, as some dogs will need to go twice or perhaps even three times during walks.

Some dog owners are not willing to admit that their pets is a challenge or troublesome. Rather than dislike the suggestions that dogs should be kept under control, you should see it as your duty to protect other dogs, children and anyone else from harm. Do know troublesome behaviors such as aggression (攻击) towards other dogs or children and make every effort to keep your dog under control. Avoid areas where you know other dogs or children will be. They can do this by showing respect for other people’s property, picking up after their dog and by keeping challenging dogs under control.

1. The writer advises dog walkers to show consideration mainly for having_____.

A．a clean car	B．a comfortable home
C．a good environment	D．a very pleasant park

2. What does the underlined word “nasty” in paragraph 2 probably mean?

A．Highly unpleasant or annoying.	B．Very boring and tiring.
C．Specially disappointing	D．Surprising or astonishing.

3. If dog waste is found in public in England the dog’s owner will be______.

A．fined more than ￡1,000	B．ordered to pick it up at once
C．ordered to give one one waste bag	D．considered to break the law.

4. What does the writer mainly want to tell the owners in the last paragraph?

A．To keep their dogs under control.	B．To try to make their dogs keep clean.
C．To stop their dogs from being harmed.	D．To respect other people’s property.
