At an auction (拍卖会) last Thursday, Kevin Lipton paid $2,585,000 for the Birch Cent, a made in 1792 that is its engraver (刻版师), Robert Birch. It’s the most money paid for a one-cent piece. And yes, he said, the purchase made . “It’s like our very first penny,” Lipton, 55, told the Los Angeles Times on Sunday. “It’s such a(n) coin. It’s so important, so rare.”

The coin is 10 similar coins known to exist that were produced after the founding of the U.S. Mint (美国造币厂), said Jim Halperin, co-chairman of Heritage Auctions. It features a profile face Miss Liberty, framed by a motto that was later abandoned, “Liberty Parent of Science & Industry.”

Lipton, who owns a coin wholesaling business (批发业务) in Beverly Hills, had been eyeing the Birch Cent he saw it in 1981 at a New York auction house. That year, Johns Hopkins University consigned (拍卖、寄售) the penny for auction, and it was by New York City developer Donald G. Patrick $200,000. Patrick consigned the coin to Texas-based Heritage Auctions. At the Orlando auction where Lipton the Birch Cent, he bought a quarter dollar from 1792 for $2,232,500. , he paid about $4.8 million for 26 cents.

Lipton has coins since he was 12 years old, and his full-time coin business _ when he was just 17. He that he was nervous about spending so much money, but now he’s his million-dollar coins will mature. “They are a great store value, and will only be worth more ,” Lipton said. ‘‘They are Mona Lisas of our coinage.’’

Plastic is everywhere because plastic is an extremely useful material.It is cheap, strong and lightweight.What’s more, it can take on nearly any form or shape, from soft and stretchy (有弹性的) to hard and glasslike.

Plastic, however, is far from perfect.It may even be bad for us.Studies now suggest that poisonous chemicals can get out of some types of plastic, get into our bodies, and cause a variety of health problems, including cancer, birth defects and attention deficit hyperactivity disorder (注意缺陷障碍).

Two types of chemicals in particular have raised special concern lately.They are called phthalates (邻苯二甲酸盐) and Bisphenol-A (二酚基丙烷), BPA for short. Not all plastic products contain them.But the ones that do are surrounded by controversy (争议).That’s because experts disagree on how dangerous these chemicals are.

Plastic is a single word, but plastic isn’t just one thing.What all plastics share in common are plasticizers -- special chemicals that allow the material to be changed into nearly any shape or texture.Plasticizers (塑化剂) are added to plastic during the manufacturing process.

Phthalates and BPA are two types of plasticizers that work in different ways.Phthalates add softness to things like shampoo bottles, raincoats and rubber.They are also used in perfumes and makeup.BPA, on the other hand, gives a hard, clear, almost glasslike feel to products such as infant bottles.BPA also appears in food and soda cans, DVDs and other unexpected places.

How do these chemicals get into us? When plastic is heated in the microwave or dishwasher, chewed on or scratched, the chemicals can seep (渗透) out of the plastic.Even though we can’t see them, we eat them, drink them and breathe them in.

Scientists and parents are especially worried about young children, who tend to chew on everything, including plastic.Dozens of countries, including the European Union, Japan, Canada and Mexico have already banned phthalates from products made for children younger than three.California and Washington have done the same.And a number of other states are considering similar rules.As for BPA, Canada became the first country to ban the chemical from baby bottles.A dozen states are considering it.

1.What can we know about the plastic from the first paragraph?

A.Its characters and effects. B.Its wide use and bad points.

C.Its importance and chemicals. D.Its popularity and advantages.

2.Which of the following products contains BPA?

A.A soft plastic cup. B.A pencil eraser.

C.A baby milk bottle. D.A new perfume.

3.Phthalates and BPA can get into us __________.

A.through mouth or nose

B.through blood transfusion

C.by feeling plastic products

D.by heating in the microwave

4.What is the passage mainly about?

A.A new ban on plastic products.

B.Problems caused by the plastic.

C.Good points of the plastic.

D.The use of plasticizers.

British MPs (国会议员) have voted in favour of the creation of babies with DNA from two women and one man, in a historic move. The UK is now set to become the first country to introduce laws to allow the creation of babies from three people. In a free vote in the Commons, 382 MPs were in favour and 128 against the technique that stops genetic diseases being passed from mother to child. During the debate, ministers said the technique was “light at the end of a dark tunnel” for families.

A further vote is required in the House of Lords. If everything goes ahead then the first such baby could be born next year. Supporters said it was “good news for progressive medicine” but critics say they will continue to fight against the technique that they say raises too many ethical (伦理的) and safety concerns. Estimates suggest 150 three-person babies could be born each year.

Prime Minister David Cameron said: “We're not playing god here; we're just making sure that two parents who want a healthy baby can have one.” The method, which was developed in Newcastle, should help women like Sharon Bernadi, from Sunderland, who lost all seven of her children to mitochondrial (线粒体的) disease. Ms Bernadi said she was “overwhelmed” by the decision.

Mitochondria are the tiny compartments (隔间) inside nearly every cell of the body that transform food into useable energy. They have their own DNA, which does not affect characteristics such as appearance. Defective mitochondria are passed down only from the mother. They can lead to brain damage, muscle wasting, heart failure and blindness. The technique uses a modified version to combine the DNA of the two parents with the healthy mitochondria of a donor woman. It results in babies with 0.1% of their DNA from the second woman and is a permanent change that would be passed down through the generations.

1. According to the passage, which of the following statements is NOT true?

A. The new technique is intended to provide the parents a healthy baby.

B. The mitochondrial disease can lead to various fatal illnesses.

C. Britain is the first country to have created three-person babies.

D. All of Ms Bernadi’s children died of a genetic disease.

2. The underlined word “defective” is closest to the meaning of ________.

A. strangely-made B. normally developed

C. functioning perfectly D. not functioning properly

3. It can be inferred from the passage that ________.

A. Mitochondria are inside nearly every cell that change food into useable energy

B. DNA of Mitochondria can affect a person’s appearance

C. in medical science ethical factors should be taken into consideration

D. the donor woman’s DNA will not be found in the three-person baby

4. Prime Minister David Cameron _________ the creation of such babies.

A. is in favour of B. throws doubt on

C. objects to D. is indifferent to
