【題目】If you’re DIY-minded, you can build your own solar power system. In some you can even build your own solar panels, although the amount that you can effectively DIY home solar depends on how much you want to power. Making your own solar panel is a time-consuming process and requires some electrical skills. However, it can also be very regarding—leaning to build your own panel is a great way to understand how electricity in generated.

Before you can build your own solar panels, you first need to understand how solar cells generate electricity. Once you’ve bought individual solar cells (they can be purchased online), the basic process for building your own solar panel goes like this: Prepare the backing for your panel. Many DIY solar panel builders prefer to use a wooden board as the base for their solar cells.

You’ll need to drill holes m the board so that the wires for each cell can pass through. Wire your solar cells together. This requires some experience for electrical work. Use a soldering iron (烙鐵) to attach wire to the solar cells and then link each of the cells together. Attach cells to your backing. If possible, attach each solar cell to the backing individually. This makes it easier to replace a single cell in the event that becomes damaged or is not operating properly.

At this point you have a functional solar panel that can produce electricity when the sun shines. However, a solar panel by itself is not useful. If you are trying to generate electricity to power devices in your home, you need to pair your panel with inverter (轉(zhuǎn)換器) that will turn direct current (DC) power from the sun into alternating current (AC) power used in most electronic devices.

【1】What does the author think of building DIY solar panel in paragraph 1?

A. It is easy. B. It is necessary.

C. It is common. D. It is worthwhile.

【2】What’s the first step of building your own solar panel?

A. Master the advanced knowledge of science.

B. Buy individual solar cells.

C. Prepare the backing for your panel.

D. Drill holes in the wooden board.

【3】Why are solar cells connected to the wooden board separately?

A. To produce more power.

B. To pass through the wooden board easily.

C. To attach cells to the backing tightly.

D. To substitute damaged cells easily.

【4】What can be inferred from the text?

A. People with electrical skills have advantages over those without in DIY solar panels.

B. A functional solar panel can give power to your home devices directly.

C. How to pair an inverter depends on how much power you want to power.

D. A wooden board is a must for your own solar panels.

【題目】 Even as a bush fire threatened the rural Australian community, Gary Wilson and his partner Julie Willis decided not to flee their wooden house.

The two had a home full of baby kangaroos to protect. More than 10 of the baby kangaroos — called joeys — stayed safe inside fabric pouches (育兒袋) that hung in the couple's living room. Each piece of cloth looked like the opening in which mother kangaroos carry their young. Wilson and Willis have taken care of wild animals before. Recently, full-grown kangaroos and other wildlife that had left their care long ago came back to the house in search of protection as the fires grew nearer. 'We had too many animals in the house and around the house so we really couldn't go, ' Wilson said. 'We decided we were going to stay and fight. ' Their home is now surrounded by burned land and vehicles.

Wilson and Willis defended their home with fire extinguishers (滅火器) and water pumps. Their house also had a special device on top that sprayed water on hot ashes falling on the roof.

Good preparation and good luck helped the building stay safe. And the animals have survived. But the fire killed two of Wilson's neighbors. 'It was a horrible thing. ' Wilson said.

Willis said, 'It's not until after the fires when it really hits you how close you were to dying... '

While Wilson and Willis usually care for joeys that are rescued after their mothers are struck by vehicles, they are now welcoming an increasing number of fire orphans.

She said, 'We didn't have children ourselves; this is what we spend our time doing. We think it's worthy — a worthy cause — looking after our babies no matter what they are... '

【1】We can learn from the passage that ______ .

A.Wilson and Willis took care of kangaroos only

B.Wilson and Willis decided to leave their wooden house

C.Wilson and Willis made pouches for baby kangaroos

D.Wilson and Willis had to look after their own babies

【2】The underlined phrase 'fire orphans' refer to ______.

A.firefighters who come to help them

【題目】Lleyton Hewitt was born in Adelaide, Australia on 24 February, 1981. His mother is a former champion netballer, his father is a league footballer, and his sister is already ranked number one in Australia for her age in tennis. She has achieved already more in tennis than Lleyton had at the same age.

The Hewitts have a grass court at their home. This was where young Lleyton began his tennis career. When Lleyton showed an unusual ability for a 4-year-old and he was hitting balls consistently over the net, his parents decided it was time to find him a coach.

“Rather than get into bad habits, it was best he learnt how to hit the ball correctly.” says his father. Two years later, they got Peter Smith as his coach.

At the age of five, when most children that age are playing hide and seek or getting into all sorts of trouble, Lleyton and his family would make the trip to Melbourne for the Australian Open. Lleyton would sit for up to 12 hours a day watching players practise.

Lleyton’s career as a tennis player was planned by his parents who tried their best to keep him away from football. Lleyton’s parents thought it was too risky to play football since he might get hurt. Had Lleyton played football, it is quite possible he may have ended up playing for his favorite team—the Adelaide Crows. As his mother says, “I guess we’ve guided him into things we felt good for him before he did.”

By the time Lleyton was eight, he was winning “under-10 games” and always won a year ahead of his age. A professional career was looking very promising. Lleyton officially turned pro in 1997.

【1】Why does Lleyton’s parents disapprove of him playing football?

A. They want him to learn from his sister.

B. They think playing football is dangerous.

C. They think tennis is more potential.

D. They can’t afford a coach.

【2】From the passage, we know “the Adelaide Crows” is ________.

A. a basketball team B. a football team

C. a university D. a company

【3】We can infer from the passage that________.

A. Lleyton’s parents decide everything for their son.

B. Lleyton’s sister is more famous than him

C. Lleyton showed a talent for football at a very young age.

D. Lleyton works very hard to achieve his dream.

【4】What’s the best title of the passage?

A. A sports family B. A wise decision

C. A tennis star D. A promising career.
