【题目】 Families should reduce exposure to synthetic chemicals found in food colorings, preservatives and packaging materials as a growing body of research shows they may harm children’s health, according to a policy statement and technical report from the American Academy of Pediastrics released online.

The statement also suggests improvements to the food additives regulatory system, including updating the scientific foundation of the U.S. Food and Drug Administrations safety assessment retesting all previously approved chemicals.

Leonard Trasande ,the author of the policy statement, to tell us more about these concerns.

Q: What are the growing number of studies showing us?

A: Over the past two decades, an accumulating body of science suggests some food additives can interfere with a child’s hormones, growth and development.

Potentially harmful effects of food additives are of special concern for children because they are more sensitive to chemical exposures because they eat and drink more relative to body weight, than adults do and are still growing and developing. An early injury to their organ systems can have lifelong and permanent consequences.

Q: What additives does the statement highlight?

A: The additives of most concern, based on rising research evidence cited in the report, include:

Bisphenols, such as BPA, used to harden plastic containers and line metal cans, can act like estrogen(雌激素)in the body which may potentially change the timing of puberty, decrease fertility, increase body fat and affect the nervous and immune systems. BPA is now banned in baby bottles.

Phthalates, which make plastic and vinyl tubes used in industrial food production flexible, may affect male genital development increase childhood obesity and contribute to cardiovascular disease. In 2017, the Consumer Product Safety Commission banned the use or some phthalates in child-care products such as teething rings.

B. update the food safety assessment program and check the approved chemicals again

C. improve the food additives regulatory system and retest all approved chemicals

D. reduce the usage of food additives and establish new food protection system

B. children usually eat and drink more unhealthy food than adults

D. children’s organs are easier to be damaged and hard to recover

【题目】 The okapi is a mammal living above the equator in one of the most biodiverse areas in central Africa. The animal was unknown to the western world until the beginning of the 20th century, and is often described as half-zebra, half-giraffe, as if it were a mixed-breed creature from a Greek legend. Yes its image is prevalent in the Democratic Republic of Congo-the only country in the world where it is found living in the world. The okapi is to Congo what the giant panda is to China or the kangaroo to Australia.

Although the okapi has striped markings resembling those of zebras’, it is most closely related to the giraffe. It has a long neck, and large, flexible ears. The face and throat are greyish white. The coat is a chocolate to reddish brown, much in contrast with the white horizontal stripes and rings on the legs and white ankles. Overall, the okapi can be easily distinguished form its nearest relative. It is much smaller (about the size of a horse) and shares more external similarities with the deer than with the giraffe. While both sexes possess horns in the giraffe, only males bear horns in the okapi.

The West got its first whiff of the okapi in 1890 when Welsh Journalist Henry Morton Stanley had puzzled over a strange “African donkey” in his book. Other Europeans in Africa had also heard of an animal that they came to call the “African unicorn.” Explorers may have seen the fleeting view of the striped backside as the animal fled through the bushes, leading to speculation that the okapi was some sort of rainforest zebra. Some even believed that the okapi was a new species of zebra. It was only later, when okapi skeleton was analyzed, that naturalists realized they had a giraffe on their hands.

In 1987, the Okapi Wildlife Reserve was established in eastern Congo to protect this rare mammal. But decades of political turbulence has seen much of the Congo’s natural resources spin out of the government’s control, and okapi numbers have fallen by 50 percent since 1995. Today, only 10,000 remain.

A.B.

C.D.

2Which of the following descriptions is true about the okapi?

A.It is an important symbol of Congo.

B.It has been well protected since 1987.

C.It is a mystical creature from a Greek legend

D.It is more closely related to the zebra than the giraffe.

3What does the underlined word“whiff”most likely mean in Paragraph 3?

A.Firm belief.B.Kind intention.

C.Strong dislike.D.Slight trace.

4What can be inferred about Henry Morton Stanley?

A.He was the first Europeans to analyze okapi skeleton.

B.He had found many new species of animals in Africa.

C.He did not know the“African donkey"in his book was the okapi.

D.He had seen the backside of an okapi dashing through the bushes.
