The federal school lunch program for 30 million low-income children was created more than half a century ago to combat malnutrition(营养不良). A breakfast program was added during the 1960s, and both attempted to improve the nutritional value of food served at school.
More must be done to fight the childhood obesity(肥胖) epidemic, which has caused a frightening peak in weight-related disorders like diabetes, high-blood pressure and heart disease among young people. The place to start is schools, where junk food sold outside the federal meals program—through snack bars and vending machines—has pretty much canceled out the benefits of all those efforts.
Federal rules that govern the sales of these harmful foods at school are limited and have not been updated for nearly 40 years. Until new regulations are written, children who are served healthy meals in the school cafeteria will continue to buy candy drinks and high sodium(钠) snacks elsewhere in school.
Many states’ school districts have taken positive steps, but others are likely to resist, especially districts that sell junk food to finance athletic program extracurricular activities, and even copier expenses.
Those districts should take note of a study released in 2009 in West Virginia showing that the budgetary costs of switching from sodas to healthy drinks such as fruit juice, milk, and water were very little. Even if the switch costs money, so be it. The school should not be trading their students’ health to buy office supplies.
Over the last five decades, the obesity rates for adolescents have tripled. Unless there is decisive action, weight and inactivity-related disorders will bother a steady larger proportion of the work force and replace smoking as the leading cause of premature death.
1.According to this passage, ______ are to blame for the childhood obesity.
A. weight-related disorders
B. high calorie snacks
C. parents’ bad habits
D. unhealthy lunches and breakfast
2.Which is the main idea of Paragraph 3?
A. Federal governments deserve high praise for their school lunch program.
B. New regulations are badly in need of updating.
C. Children should be forbidden to buy snacks in school.
D. Federal rules encourage snacks outside the school program.
3.The passage is concerned mainly with ______.
A. Malnutrition in low-income children
B. The federal school lunch program
C. obesity at school
D. the nutritional value of food served at school
4.The tone of this passage is ______.
A. negative B. indifferent
C. optimistic D. ironic
Zero gravity looks cool. But what about the thing no one likes to talk about? Yes, that is right: going to bathroom. Zero gravity makes this everyday task quite a challenge. Astronauts have to be toilet-trained all over again.
The Apollo astronauts raised themselves off the seat of their chairs and stuck a clear plastic bag to their back sides with sticky strips. A second astronaut watched closely to be sure no waste matter escaped the seal. (You would not want that stuff floating around the cabin!) When the deed was done, the astronaut cleaned up with a piece of plastic attached to the inside of the bag, removed the bag, dropped a disinfectant pill in with the waste matter, and put the whole thing, sealed, into a special container.
Donald W. Rethke, an engineer for Hamilton Standard Space Systems, developed a more private way to answer nature’s call: the space toilet. It is somewhat like the kind of toilet one would find on commercial airplanes --- with unique adaptations for zero gravity, of course. For instance, it has thigh bars that keep the astronaut from floating off the seat.
The astronaut (male or female) defecates (排便) in a bag and urinates (排尿) in a hose. Solid and liquid wastes are kept separated because at least 85% of the urine is recycled and, yes, after careful filtration, used for drinking and other purposes. (Water is always in demand in space.) A vacuum sucks the waste materials into the toilet, where the waste is compacted into hamburger-like patties for easy storage. Although not exactly like an earthbound visit to the toilet, it is at the very least much more private than in the early days of space travel.
1.According to the first paragraph, the lack of the gravity can turn something as simple as _______ into a major challenge.
A. eating B. taking baths
C. sleeping D. answering nature’s call
2.How did astronauts use toilet systems in the Apollo days?
A. None of the waste was separated as it is now.
B. Solid waste was compressed and stored on board.
C. The toilet units used water to remove the waste through the system.
D. The astronauts each used their own private restroom.
3.To ensure the user remains seated, the toilet comes equipped with _______
A. a plastic bag B. a sticky strip
C. a wide hose D. a thigh bar
4.What can be inferred from the fact that most of the astronauts’ urine is recycled?
A. The recycled water tastes better.
B. Water is limited on the space shuttle.
C. It is very convenient to get their urine recycled.
D. Space science includes recycling urine.
Today, paper-making is a big business. But it is still possible to make paper by hand, since the steps are the same as using big machines.
You should use paper with small amounts of printing. Old envelopes are good for this reason. Colored paper also can be used, as well as small amounts of newspaper. Small pieces of rags or cloth can be added. These should be cut into pieces about five centimeters by five centimeters.
Everything is placed in a container, covered with water and brought to a boil. It is mixed for about two hours with some common chemicals and then allowed to cool. Then it is left until most of the water dries up. The substance left, called pulp(纸浆), can be stored until you are ready to make paper.
When you are ready, the pulp is mixed with water again. Then the pulp is poured into a mold. The mold is made of small squares of wire that hold the shape and thickness of the paper. To help dry the paper, the mold lets the water flow through the small wire squares.
After several more drying steps, the paper is carefully lifted back from the mold. It is now strong enough to be touched.
The paper is smoothed and pressed to remove trapped air. You can use a common electric iron used for pressing clothes.
1.It is suggested that we “should choose paper with small amounts of printing” to_____.
A. make paper by ourselves
B. renew the old envelopes
C. make various colored paper
D. create our own newspaper
2.Whether the paper is strong enough to be touched is determined by _____.
A. how long the pulp is stored
B. how thick the paper is
C. how much water remains
D. what type of chemicals are used
3.When the paper is lifted from the mold, it is time to _____.
A. make it smooth B. make it strong
C. decorate it D. use an iron
4.The passage is most probably intended to _____.
A. introduce the history of paper-making
B. describe the process of paper-making
C. compare the ancient with the modern paper-making
D. argue about the possibility of paper-making by hand

The Minions
These yellow creatures become a big hit for their cuteness of loving bananas, nonsense words and silly movements. When you watched Despicable Me (2010), did you predict the Minions would later become the main attraction? From background characters and then main characters, their success proves good animated creations can take on a life of their own spin-offs(续集)
The penguins
The penguins were originally just sidekicks in Madagascar(2005). But in 2008 they took leading roles in their own TV series, and in 2014 starred in the film Penguins of Madagascar. The penguins’ wit, sarcasm and crafty composure not only adds attraction to the kid-friendly franchise, but also serves adult audiences well. So it's not surprising that they got their own movie.
Scrat
A small and furry squirrel with a long tail from animated movie Ice Age(2002), Scrat has won people’s hearts with its persistence in acorns. It is a big part of its(Ice Age’s) enduring appeal. He demands a lot of nuts, but he is a superstar, and he does his own stunts. Scrat now has his own animated shorts, extended scenes and mini-movies.
Puss in Boots
Originally a fairy tale written by French author Charles Perraut, Puss in Boots features a cat that helps his low-born master gain wealth and power through trickery. The cat later appeared in the Shrek franchise. In 2011, he had his own movie fittingly titled Puss in Boots.

Dear Mandy，
I'm not doing well in my lessons at school，especial in maths. My dad says I must try hard because he wants me go to university. He thinks I'm lazy，but it's not true. I work really hard，often study late into the night! I've tried to talk to my mother，but she always said I have to work as hard like my brother does. My brother doesn't study very hard，and he always gets excellent grades. It's not fair!
The only thing I like it is art. My teacher says I'm the best student she's had for year. When I told my dad，all he said was，“ You mustn’t waste your time in art. You must focus your mind on your lessons! ”
I'm feeling quite puzzling as to what to do now. Would you please help me out?
Thanks a lot!
Yours sincerely， Lisa
