A recent university study found that current electric cars could be used for 87% of daily car journeys in the US. That figure could rise to 98% by 2020.

One hurdle to the widespread adoption of electric cars has been “range anxiety” ---drivers’ concerns about running out of petrol on a journey. While petrol stations are conveniently located across national road systems, the necessary network of electric charging stations is still being developed. In fact, charging points are becoming increasingly common throughout the USA.

Attitudes towards electric vehicles have changed quite considerably over the last few years. Not that long ago, electric cars met with doubt, and their high price drove customers away. Thanks to improvements in battery capacity(电池容量), recharging times, performance and price, the current generation of electric cars is starting to persuade critics.

As well as progress on the road, electric vehicles are taking to the sea and sky. Electric boats are among the oldest electric vehicles, having enjoyed several decades of popularity from the late 19th to the early 20th century before petrol-powered outboard motors took over. Now, the global drive for renewable energy sources is bringing electric boats back. Steps towards electric planes are also being made, with Airbus and NASA among the organizations developing and testing battery-powered planes. The experiments could soon make electric flight a reality.

Electric vehicles do not produce any emissions(排放物). Were the US to act on the study’s findings and replace 87 percent of its cars with electric vehicles, it would reduce the national demand for petrol by 61 per cent. However, because of the production processes and the generation of electricity required to charge these vehicles, they cannot claim to be completely emission-free. Even so, as many countries continue to increase their use of renewable energy sources, electric vehicles will become even cleaner.

1.The underlined word “hurdle” refers to ________.

2.Why were not the electric cars popular with many people in the past?

3.What is the purpose of Paragraph 4?

A. To show why more people have interest in electric cars.

B. To describe different ways electric vehicles can be used.

C. To introduce the history of electric vehicles

D. To explain why the world needs more electric cars.

4.Which of the following can be the best title for this passage?

With an overwhelming variety of educational toys and learning tools in the market, you really wonder if these educational products are really beneficial to children. There have been many educational DVDs in the market that promise to stimulate a child’s learning and enhance his or her cognitive skills. Parents feel good about buying these products for their children. After all, these educational tools try to do a parent’s job of participating in the child’s education, especially when the parent can’t be present due to his or her busy schedule.

Moreover, children seem to love these DVDs that contain pictures, words, and loads of stories. Some DVDs contain fun, sing-along songs or read-aloud words to help the children learn different concepts and words. Although these are fun for the parents and the children, the question that needs to be asked is whether these DVDs are actually beneficial to the child, as they claim to be.

Although parents expected “educational” products to give their child some educational advantage, research has shown otherwise. Researchers in a recent study concluded that there was indeed no difference between the language and cognitive ability of the infants who were repeatedly exposed to educational DVDs and those who were not exposed to the DVDs. In fact, contrary to expectations, it was found that babies who were exposed to the DVDs at an earlier age had lower overall language scores at a later age. This suggested a damaging effect of such DVDs on younger children.

For several years the American Academy of Pediatrics has recommended that toddlers under age of 24 months or 2 years should not watch videos or television. However, there are many parents who believe these DVDs really help in stimulating the child and keep him or her entertained.

While it may work as a great babysitter, it is important to limit activities like video games, computer games, DVDs or TV programs. To promote their children’s development and cognitive skills, parents are advised to spend time with their children and increase interaction with them. For example, if you want to enhance language development, converse with the child, listen, and respond to whatever the child is trying to communicate. Children learn more by interacting with parents, rather than by watching DVDs.

1.Many parents love to buy educational DVDs for their children actually because ________.

A. their children have great interest in these DVDs

B. they are sure that these DVDs are beneficial to children

C. these DVDs can share their participation in children’s education

D. these DVDs are effective in improving children’ s cognitive skills

2.According to the study mentioned in Paragraph 3, educational DVDs ________.

A. need proper regulations

B. have only few advantages

C. are helpful for older children

D. are harmful to younger children

3.What is the author’s advice on promoting children’s development and cognitive skills?

A. Making a careful schedule for children’ s education.

B. Increasing interaction between parents and children.

C. Keeping the children entertained and interested.

D. Seeking support and advice from experts.

4.Which of the following might be the best title for the passage?

A. Do educational DVDs Really Work?

B. Are You Prepared for Educational Tools?

C. Are You Leading Your Child to the Right path?

D. What Should You Do for Your Child’s Education?

The health of millions could be at risk because supplies of medicinal plants are being used up. These plants are used to make traditional medicine, including drugs to fight cancer. “The loss of medicinal plants is a quiet disaster,” says Sara Oldfield, secretary general of the NGO Botanic Gardens Conservation International.

Most people worldwide rely on herbal (药草制的) medicines which are got mostly from wild plants. But some 15,000 of the 50,000 medicinal species are under threat of dying out, according to report from the international conservation group Plantlife. Shortages have been reported in China, India, Kenya, Nepal, Tanzania and Uganda.

Over-harvesting does the most harm, though pollution and competition from invasive species (入侵物种) and habitat destruction all contribute. Businessmen generally harvest medicinal plants, not caring about sustainability (可持续性),” the Plantlife report says, “damage is serious partly because they have no idea about it, but it is mainly because such collection is unorganized”. Medicinal trees at risk include the Himalayan yew (紫衫) and the African cherry, which are used to treat some cancers.

The solution, says the report’s author, Alan Hamilton, is to encourage local people to protect these plants. Ten projects studied by Plantlife in India, Pakistan, China, Nepal, Uganda and Kenya showed this method can succeed. In Uganda, the project has kept a sustainable supply of low-cost cancer treatments, and in China a public-run medicinal plant project has been created for the first time.”

“Improving health, earning an income and keeping cultural traditions are important in encouraging people to protect medicinal plants,” says Hamilton, “You have to pay attention to what people are interested in.”

Ghillean Prance, the former director of the Royal Botanic Gardens at Kew in London, agrees that medicinal plants are in need of protection. “Not nearly enough is being done,” he told New Scientist. “We are destroying the very plants that are of most use to us.”

1.From the first two paragraphs, we can learn that ________.

A. millions of people are threatened with cancer

B. most countries see a shortage of herbal medicines

C. about two thirds of medicinal species will disappear

D. a number of medicinal species are in danger of extinction

2.The major factor that causes the decreasing of supplies of medicinal plants is ________.

A. over-harvesting　　 B. habitat destruction

C. pollution　　 D. invasive species

3.The underlined word “it” in Paragraph 3 refers to ________.

A. pollution　　 B. other species’ invasion

C. sustainability　　 D. over-harvesting

4.What can be inferred from the passage?

A. Protecting medicinal plants has a long way to go.

B. Local people don’t know how to protect medicinal plants.

C. Ghillean Prance is optimistic about medicinal plants’ future.

D. China has made great progress in protecting medicinal plants.
