Last Christmas my older sister Jane got a unicycle (独轮脚踏车) she had requested. I thought it kind of strange, wondering why she would want something like that. She did ride and practice for a while, but eventually stopped.

Curious, I tried it, finding it very hard and thinking it impossible for a weak girl like me to learn. Since our dining room of our old house had low beams (屋梁), I used them like monkey bars to practice riding, which helped a lot. Because I thought it was really fun, I practiced every spare moment I had, teaching myself to go forwards, backwards and to turn. Practicing was something I loved to do in my spare time, but it did get discouraging when I fell. After months of practicing, I finally made it.

One morning, our teacher Maria excitedly announced that a school talent show was to be held to raise money for charity. She encouraged my classmates to sign up for it. I’m not always best in front of a crowd, which was why I was very nervous when I meant to put on my performance by doing a hula hoop (圈) and riding a unicycle on stage. But I overcame my fear and entered myself for the talent show, for which I practiced a lot in case I should mess up.

My routine (整套动作) was to do the hula hoop from my neck, down to my stomach, then to my knees. After that, I was to ride my unicycle forwards and backwards on stage. Lastly I would do the hula hoop while riding the unicycle. I was to do all this accompanied by my carefully selected music. I wondered what people from my seventh grade would think of my performance. With my friends inspiring me, I built up my confidence. On the night of the show, many people found out there was going to be a unicycle performance, so more came, even the headmaster.

Para. 1: I was both nervous and excited when it was my turn.

6 . It is often difficult for farmers to identify diseases quickly enough to protect their crops and those on neighboring farms. Now, some farmers are using a simple device directly in the field to find viruses before they spread.

In Tanzania, several viruses are a threat to cassava crops. Farmers struggle to identify the diseases in an urgent effort to avoid severe crop damage. The disease identification process is often difficult when farmers are acting on their own. If they do not know what is attacking their crops, they cannot decide the best way to fight the disease. A device from British technology company Oxford Nanopore is changing that. The device extracts deoxyribonucleic acid, better known as DNA, from plants. DNA is the carrier of genetic information in nearly all living things. The device helps farmers identify what is harming their crops so they can change to more resistant crops.

Laura Boykin is with the University of Western Australia and also works with the Cassava Virus Action Project. She brought the device to a Tanzanian farm owned by Asha Mohamed. She said, “We are here collecting leaf punches from infected material to test, to do a DNA extraction and then start sequencing (排序) in the field.” The testing identified a number of viruses in the cassava fields near Mohamed’s farm. The process also discovered that plants considered resistant to disease had a very low viral level. Once the viruses were identified, Asha Mohamed was given two kinds of seeds that are resistant to the diseases.

In another case, DNA was collected from a pawpaw tree farm in Kenya. With that test, the technology was able to identify diseases affecting Naomi Mumo’s crops. Naomi Mumo said, “All my pawpaw were affected by a disease, and I didn’t know what kind of disease it was. But now, I have people who have identified the disease using new technology, and within a very short time. So I’m very happy.”

The speed at which farmers identify diseases can mean the difference between the success or failure on large areas of crop land. Now, the use of such simple and easily transportable DNA sequencing devices is making that possible.

7 . We may think we're a culture that gets rid of our worn technology at the first sight of something shiny and new, but a new study shows that we keep using our old devices(装置) well after they go out of style. That’s bad news for the environment — and our wallets — as these outdated devices consume much more energy than the newer ones that do the same things.

To figure out how much power these devices are using, Callie Babbitt and her colleagues at the Rochester Institute of Technology in New York tracked the environmental costs for each product throughout its life — from when its minerals are mined to when we stop using the device. This method provided a readout for how home energy use has evolved since the early 1990s. Devices were grouped by generation — Desktop computers, basic mobile phones, and box-set TVs defined 1992. Digital cameras arrived on the scene in 1997. And MP3 players, smart phones, and LCD TVs entered homes in 2002, before tablets and e-readers showed up in 2007.

As we accumulated more devices, however, we didn't throw out our old ones. "The living-room television is replaced and gets planted in the kids' room, and suddenly one day, you have a TV in every room of the house," said one researcher. The average number of electronic devices rose from four per household in 1992 to 13 in 2007. We're not just keeping these old devices — we continue to use them. According to the analysis of Babbitt's team, old desktop monitors and box TVs with cathode ray tubes are the worst devices with their energy consumption and contribution to greenhouse gas emissions（排放）more than doubling during the 1992 to 2007 window.

So what's the solution（解决方案）? The team's data only went up to 2007, but the researchers also explored what would happen if consumers replaced old products with new electronics that serve more than one function, such as a tablet for word processing and TV viewing. They found that more on-demand entertainment viewing on tablets instead of TVs and desktop computers could cut energy consumption by 44%.

1. What does the author think of new devices?

A．They are environment-friendly.	B．They are no better than the old.
C．They cost more to use at home.	D．They go out of style quickly.

2. Why did Babbitt's team conduct the research?

A．To reduce the cost of minerals.

B．To test the life cycle of a product.

C．To update consumers on new technology.

D．To find out electricity consumption of the devices.

3. Which of the following uses the least energy?

A．The box-set TV.	B．The tablet.
C．The LCD TV.	D．The desktop computer.

4. What does the text suggest people do about old electronic devices?

A．Stop using them.	B．Take them apart.
C．Upgrade them.	D．Recycle them.
