Priscilla Ouchida’s “energy-efficient” house turned out to be a horrible dream. When she and her engineer husband married a few years ago, they built a $100,000 three-bedroom home in California. Tightly sealed to prevent air leaks, the house was equipped with small double-paned (双层玻璃的) windows and several other energy-saving features. Problems began as soon as the couple moved in, however. Priscilla’s eyes burned. Her throat was constantly dry. She suffered from headaches and could hardly sleep. It was as though she had suddenly developed a strange illness.
Experts finally traced the cause of her illness. The level of formaldehyde (甲醛) gas in her kitchen was twice the maximum allowed by federal standards for chemical workers. The source of the gas? Her new kitchen cabinets and wall-to-wall carpeting.
The Ouchidas are victims of indoor air pollution, which is net given sufficient attention partly because of the nation’s drive to save energy. The problem itself isn’t new. “The indoor environment was dirty long before energy conservation came along,” says Moschandreas a pollution scientist at Geomet Technologies in Maryland. “Energy conservation has tended to accentuate the situation in some cases.”
The problem appears to be more troublesome in newly constructed homes rather than old ones. Back in the days when energy was cheap, home builders didn’t worry much about unsealed cracks. Because of such leaks, the air in an average home was replaced by fresh outdoor air about once an hour. As a result, the pollutants produced in most households seldom build up to dangerous levels.

A. control B. worsen C. relieve D. improve
4. This passage is most probably taken from an article entitled “_________”.
A. Energy Conservation B. Houses Building Crisis
C. Air Pollution Indoors D. Traps in Building Construction
When a big exam is coming up, you probably feel anxious about any wasted time and want to begin school as soon as you probably can.
But tens of thousands of British high school students will soon be getting up later. They’re taking part in a new experiment by Oxford University to see if later classes can improve their exam results.
Grades 10 students in the UK have to take the nationwide General Certificate of Secondary Education (GCSE) exams. They have to pass these exams in order to study more advanced courses, and later apply for universities.
The Oxford University project means that GCSE students from more than 100 schools across England will start school at 10 am, more than one hour later than the current start time (8:50 am).
The project is based on scientific evidence that teenagers are “out of sync(同步)” with traditional school hours, the Telegraph reported. And what they need is more sleep in the morning.
“We know that something funny happens when you’re a teenager, in that you seem to be out of sync with the world,” said professor Colin Epsie, who is leading the study. “Your parents think it’s because you are lazy and opinionated（固执己见的）and everything will be OK if you could get to sleep earlier. But science is telling us that teenagers need to sleep more in the mornings.”
Everyone follows a natural cycle of sleep and wakefulne ss. Biology has decided that teenagers go to sleep around midnight and don’t feel fully awake until 9-10 am, according to scientists. That’s two hours later than adults. And their body clocks stay like this until the age of around 21 for males, and 19 for females.
“Society provides school for learning, but the brain provides sleep. So we are exploring the possibility that if you delay the schools start time until 10 am, that will improve learning performance,” said Epsie.
The results could be positive, based on previous studies.
An early study at the UK’s Monkseaton High School in 2009 found that starting an hour later improved grades in core subjects by 19 percent.
The Oxford project is expecting to publish the results in 2018. It’s time to wait and see whether scientists will give us an excuse to get up late.

“Can you take me golfing sometimes?” my 13-year-old son asked.
I had a bathroom to remodel(改建). I wanted to say no. “Sure,” I said.”What did you have in mind ?”
“Well, maybe you could, like, pick up Jared and me after school on Friday and take us out to Oakway.”
“Sounds good.”
Friday came. In front of the school, Ryan and Jared piled in. Ryan looked confused.
“What’s with the golf hat, Dad ?” he asked
It was, I thought, a silly question, like asking a diver: “What’s with the swim fins (脚蹼)？”
“Well, I thought we were going to play some golf.”
There was a strange pause. “Uh, you’re going, too ?” He asked. Suddenly, it struck me that I hadn’t been invited. Thirteen years of parenting flashed before my eyes.
All these memories sped by in about two seconds, leaving me about three seconds to reply.
I had to say something. I wanted to say this: “How could you do this to me? We have always been a team.” But I said: “Me? Play? No. You know I’m up to my ears in the remodel project.”
We drove on in silence for a few moments. “So, how are you planning to play for this?” I asked, my wounnded ego(自我) reaching for the dagger(匕首)
“Uh, could you loan me $7?”
Oh, I get it. He doesn’t want me, but he’ll gladly take my money.
“No problem, ” I said.
I dropped him and Jared off, wished them luck, and headed for home. Life would never be the same.
I walked in the door. “What are you doing home?” my wife asked.
“I wasn’t invited.” I replied.
Another one of those strange pauses came. Then my wife laughed. Out loud. At first, I was hurt. Then I, too, laughed.
I went back to the bathroom remodel and realized that this is what life is all about: change.
A few hours later, I heard Ryan walk in the front door.
“Dad,” he said, “My game stinks(糟透了). Can you take me golfing sometime ? I need some help.”
I wanted to hug him and shout: “I’m still needed!”
Instead, I got one of those serious-dad looks on my face and said: “Sure, Ry, anytime.”After the author picked up his son and Jared at school, he ____________.

The earth is dying before us yet we sit and watch. If the TV or the game system breaks, we run off to the stores to get it fixed immediately no matter what the cost. Why aren’t we willing to fix our earth? Are our televisions and game systems more important to us than where we live? Where shall we continue to live, until the end of time?
The earth is our home and cannot be replaced. We must take care of it. We have come up with so much technology that limits us instead of helping us. Take that game system we run to repair. What does it do? It occupies kids’ time! The earth has already given kids plenty of entertainment in the forms of fields and hills, forests and plains, water and land. However, instead of using what the earth has given us, and helping kids by giving them exercise as they run around, we decide to ruin kids’ minds with game systems that glue them to the screen for hours, and make them ignore their homework and chores. We have polluted this earth by making these things which do not even help in any way!
We have already messed up this world, we have ruined the air, water, and animals that it has so willingly provided for us. We need to stop this destruction of life and bring back the world we had before. It will not be easy, but everybody can help! What about something as simple as turning the lights off when you leave a room? Recycling what can be recycled? Picking up litter? Donating money to an environmental organization? None of these things are very hard. We can’t just always say, “Oh, the earth is a mess. Ah, well, those big companies that are polluting so much can stop and fix it.” Instead, we need to help out. It’s not only those big companies; it’s everyday things that we do too that are ruining the earth. So stop and think about what you can do to make a difference to our world!Why does the author mention televisions and game systems in Paragraph 1?
| A．To make people better aware of the urgency to the protection of the earth. |
| B．To explore the great harm done to the earth by too much technology waste. |
| C．To show the relationship between overuse of those things with early death. |
| D．To remind people to spend less on them and use the saved money in a wiser way. |
It can be inferred from the second paragraph that the author________
| A．thinks we must take care of our irreplaceable home-----the earth. |
| B．thinks running around in fields occupies too much of kids’ time. |
| C．takes an extremely negative attitude to things like game systems. |
| D．takes it for granted that technology gives kids plenty of entertainment. |
We can clearly feel that the author wrote this passage with deep_______
| A．anger | B．emotion | C．sadness | D．regret |
What is the main purpose of the passage?
| A．To criticize those big companies that ruin the earth |
| B．To ask people to save kids from the harm done by pollution. |
| C．To give kids plenty of entertainment in a clean environment |
| D．To call on people to stop ruining the earth |
Washington: NASA has announced evidence that Jupiter's largest moon, Ganymede, has a saltwater ocean under its icy surface. The ocean seems to have more water than all the water on Earth's surface, according to new Hubble observation.
New Hubble observations of Ganymede's magnetic field strongly suggest that the moon, which is the largest in our whole solar system, is home to a subsurface ocean.
Scientists estimate the ocean is 95 kilometres thick, which is about 10 times deeper than Earth's oceans. But unlike our salty waters, Ganymede's ocean is buried under 150 kilometres of ice.
While scientists have speculated(推测) since 1970s about the presence of an ocean on Ganymede------the largest moon in our solar system------ until now the only observational evidence came from a brief flyby by the Galileo spacecraft, which didn’t observe the moon long enough to confirm a liquid ocean.
This discovery marks an important milestone, highlighting what only Hubble can accomplish. In its 25 years in orbit, Hubble has made many scientific discoveries in our own solar system. A deep ocean under the icy surface of Ganymede opens up further exciting possibilities for life beyond Earth.
Scientists have already confirmed the existence of an ocean on Europa, another moon orbiting Jupiter, and NASA has announced plans to send an unmanned mission there searching for the life that might come with liquid water.
Hubble is a telescope that orbits Earth, but because of its impressive gravitational analyses it can be used to study the inside of far distant planets. Using these same principles, scientists could theoretically detect oceans on distant planets as well.What can we learn about the Ganymede from the passage?
| A．It is a planet with the largest moon in our whole solar system. |
| B．Its ocean adds to people’s excitement about life beyond Earth. |
| C．It will be used by NASA as a base for the Hubble telescope. |
| D．Its liquid ocean was first proved by the Galileo spacecraft. |
Which of the following best describes the writer’s attitude towards Hubble?
| A．Cautious | B．Doubtful |
| C．Negative | D．Favourable |
What does the underlined part in Paragraph 6 mean?
| A．An underground ocean has been found in Europa. |
| B．The presence of an underground ocean in Europa is not possible. |
| C．It is now certain that there is an ocean on Europa. |
| D．No evidence has shown the existence of an ocean on Europa. |
What type of writing does this passage belong to?
| A．A term essay | B．A news report |
| C．An experiment report | D．An exploration review. |
