【题目】 Researchers in Australia have discovered an effective new method to capture the atmospheric carbon dioxide that is damaging our planet and transform it into something solid, making it much easier to store.

Carbon capture isn’t new, but previous methods call for the gas to be compressed into liquid and then injected underground. Widespread usage of that technology has been locked by economic and environmental concerns due to possible leaks. Instead, in a study published in Nature Communications, the group details their sustainable and cost-effective plan for transforming CO2 into coal.

This new process involves a liquid metal catalyst( 催化剂 )that is efficient in conducting electricity. CO2 gas is dissolved in a container with some liquid. Once electricity charge is introduced, the CO2 begins to turn into solid pieces of carbon, which can be collected and stored.

What makes this particularly unique is that the entire process can occur at room temperature. Previous experiments have only shown a gas to solid conversion at extremely high temperature, which made it impossible on a large scale. Now, the researchers are hoping that their work will be used to create even further when it comes to carbon storage.

In an interesting side benefit, the solid carbon also works as an electrode( ), which opens up a world of possibilities. “A side benefit of the process is that the carbon can hold electrical charge, becoming a super battery, so it could potentially be used as a part in future vehicles,” explains Dr. Dorna Estrafilzadeh, a researcher. “The process also produces fuel as a by-product, which could also have industrial applications.”

1What can we know about the previous carbon capture methods?

A.People have to inject liquid to the gas.

B.The previous methods can be done easily.

C.The previous methods are not very popular.

D.People have widely accepted previous methods.

2What is the special part of the new method?

A.It needs electricity to make the process efficient.

B.It can be done in any kind of container.

C.It doesn’t need extreme temperature.

D.It can produce much solid carbon.

3What can we infer from the last paragraph?

A.The method will make fossil oil disappear.

B.The method will influence the future industry.

C.The method will make developed countries more powerful.

D.The method will be used to make new vehicles.

4What is the best title for the passage?

A.How to change carbon into CO2.

B.A new carbon capture technology.

C.A new technology to get useful carbon.

D.Australia makes the world cleaner than before.

【题目】They like using the Internet. They have lots of pocket money to spend, and they spend a higher proportion of it online than the rest of us. Teenagers are just the sort of people an online seller is interested in, and the things they want to buy games, CDs and clothing are easily sold on the Web.

But paying online is a tricky business for consumers who are too young to own credit cards. Most have to use a parent’s card. They want a service that allows them to spend money.

That may come sooner than they think: new ways to take pocket money into cyber (网络的) space are coming out rapidly on both sides of the Atlantic. If successful, these products can stimulate (刺激)online sales.

In general, teenagers spend huge amounts: $153bn (billion) in the US last year and £20bn annually in the UK. Most teenagers have access to the Internet at home or at school 88 percent in the US, 69 percent in the UK. According to the Jupiter Research, one in eight of those with Internet access has bought something online mainly CDs and books.

In most cases, parents pay for these purchases with credit cards, an arrangement that is often unsatisfactory for them and their children. Pressing parents to spend online is less productive than pressing on the high street. They are more likely to ask “Why?” if you ask to spend some money online.

One way to help teenagers change notes and coins into cyber cash is through prepaid cards such as Internet Cash in the US and Smart cards in the UK. Similar to those for pay-as-you-go mobile telephones, they are sold in amounts such as£20 or $50 with a concealed (隐藏的) 14-digit number that can be used to load the cash into an online account.

1What does the word “They” in paragraph 1 refer to?

A. Sellers. B. Teenagers C. Buyers. D. Parents.

2According to the passage, which of the following statements is TRUE?

A. Most teenagers in the US and the UK have bought something online.

B. Teenagers pay for goods online with their own credit cards.

C. More than half of the teenagers in the US and the UK have Internet access.

D. Teenagers found it easier to persuade parents to buy online than in a shop.

3A new way to help teenagers shop online is to use _________.

A. prepaid cards B. special coins and notes

C. a new machine D. pay-as-you-go mobile phones

4What is the passage mainly about?

A. The arrival of cyber pocket money. B. Internet users in the US and the UK.

C. New credit cards for parents. D. Online shopping traps.
