1 . Running after fireflies （萤火虫）on a warm summer night might become a rare childhood memory if humans don't take action. There are over 2,000 different firefly species around the world, but their populations are decreasing due to artificial light pollution, pesticides （杀虫剂）and smaller habitat size.

A team of Tufts University-led researchers surveyed scientists and conservationists about the threats to firefly populations around the world. According to the study, one of the main threats to fireflies in East Asia and South America is artificial light. Fireflies light up to attract mates, but they can easily mistake human-made lights as potential partners. Adult fireflies typically live only a few days, which doesn't give them long to find a mate.

Humans' destroying the insects' natural habitats creates another threat. During their larval phase （幼虫期），Malaysian fireflies live in riverside bushes that are often pulled out for human-made fish farms. In Europe, Lampyris fireflies are finding less food to eat due to the growing urbanization of what were once woods and farmlands. In Malaysia, adult pteroptyx fireflies that usually prefer to mate in specific trees next to rivers have to find new mating areas because the trees are being knocked down for farmhouses.

The study also looked at the effects of climate change, tourism, invasive （侵入的）species and water pollution. On a positive note, while fireflies around the world seem to be suffering from the previously mentioned issues, Big Dipper fireflies living in the US happen to be booming. "Those guys can survive pretty much anywhere,said Sara Lewis, a biologist from Tufts University.

The study urges countries where firefly populations are dwindling to take measures to preserve suitable habitats, lessen light pollution, reduce use of pesticides and develop better guidelines for tourism around known firefly areas.

7 . An extreme drought is threatening South Africa's wildlife industry. Farmers are keeping fewer animals and vacationers are visiting in smaller numbers. Parts of the country have been affected by repeated years of hotter than normal weather and below average rainfall. The conditions have burned feeding grass and dried up watering holes. In 2015, the area saw the driest year on record. The agency Wildlife Ranching South Africa ( WRSA) collets data on more than 9,000 wildlife ranches ( 牧场) in the nation. It estimates that the Northern Cape Province has lost more than .two thirds of its game over the last three years. WRSA is talking to ranchers around the country to gather information on animal loss and the financial impact the drought is having.

WRSA Chief Adri Kitshoff-Botha told Reuters News Agency the drought has continued for some time. “In some areas we've seen it has been going on for six years, ”she said. The wildlife industry brings money to South Africa's economy through tourism, hunting, breeding and meat production. Hunting —the shooting of carefully chosen animals in particular—made $ 140 million in 2016, topping the list of the four mentioned, above, breeding ranking the least, though.

In the past, the lodge (度假区) was home to around 4,500 wild animals—including 35 different species from antelope to rhino. But it has lost around 1 ,000 animals because of the drought. Now, dead animals sit in old and unused mines on the edge of the property. “The lodge has seen its spending rise as it buys more feed for animals for the sake of the drought. At the same time, hunters are paying less, and fewer tourists are visiting because the animals are in poor condition over the past year,” said WRSA’s Kitshof-Botha. The drought has also hit other parts of South Africa. In Botswana, more than 100 elephants died in two months in 2019. Botswana is home to almost one-third of Africa's elephants.

1. Which is the indirect result of the drought?

A．Economy is barely declining.	B．Feeding grass has been burned.
C．Watering holes have dried up.	D．Vacationers are becoming fewer.

2. Which took the lead in South Africa's wildlife industry in 2016?

A．Hunting.	B．Breeding.
C．Tourism.	D．Meat production.

3. The lodge's expense is going up because_____

A．some local species need more attending in hot weather

B．the animals in poor condition are dying out in the drought

C．the lodge has to offer animals more food due to the drought

D．dead animals' bodies need to be buried in' old and unused mines

4. What does the passage mainly talk about?

A．South Africa's wildlife industry is under the threat of an extreme drought.

B．The rapid decreasing of national economy affects wildlife in South Africa.

C．Most wildlife ranchers in South Africa are suffering a lot from the drought.

D．Wildlife industry is playing a vital part in South Africa's national economy.

8 . An earthquake is one of the most common natural disasters. It may cause great damage. So it is wise to learn some simple safety tips to protect yourself or your family members.

Fragile items like those made of glass are easily broken and should usually be placed on a lower surface, near the ground instead of placing them in the cupboards higher up. Never place them near your bed, sofas and other furniture where you would be sitting or lying down. When there is a strong movement, these pieces will fall on the floor directly and not on you.

There is a strong chance of short circuits (短路) and fire during an earthquake. Make sure you turn off electrical connections and gas immediately when an earthquake happens.

During an earthquake, lie beneath an object that is not easily damaged. Do not go near objects that could directly fall on you. Never use the elevator to go down. Stay inside until the   shaking stops and it is safe to go outside. Research has shown that most injuries happen when people inside buildings try to go out. Use the staircases at all times.

If you are outdoors, do not take shelter under a tree, streetlights, electric poles or tall   buildings. If you are driving, stop your car and stay in a safe place. Do not park your car under a tree or any tall object.

If trapped in debris (瓦砾堆), cover your mouth with a handkerchief or clothing. Tap on a pipe or the wall so that rescuers can find you. Use a whistle (哨子) if one is able to get. Never shout for help. Shouting can cause you to breathe in dangerous amounts of dust. Do not light a match(火柴) because you may burn yourself. Do not move about or kick up dust.

1. The purpose of the passage is to tell readers__________.

A．the damage caused by earthquakes	B．the rescue work after earthquakes
C．how to prevent earthquakes	D．what to do about earthquakes

2. The underlined word “Fragile” in Paragraph 2 probably means “__________”．

A．Easily found	B．Easily broken
C．Expensive	D．Heavy

3. During the earthquake, people are advised to __________.

A．go out of the building at once	B．drive to a safe place quickly
C．take shelter under a tree	D．turn off electricity and gas immediately

4. When trapped in debris, you’d better not   ___________.

A．shout for help aloud.

B．cover your mouth with a handkerchief or clothing.

C．tap on a pipe or the wall hard so that rescuers can find you.

D．use a whistle if possible.

9 . The United Nations Environment Program is calling for urgent action to reduce growing risks from chemicals. Better management of chemicals could save millions of lives and billions of dollars. As estimated, 143,000 chemicals are now produced. Yet the report says only a small number of these chemicals have been studied for their effects on human health and the environment. It says death and disability rates are high from the unsafe use of chemical products.

Sylvie Lemmet, director of the UNEP, says poor management of chemicals has a high economic cost. For example, she says the cost is higher than the amount of overseas development aid, or ODA, for health care in sub-Saharan Africa.

She says, “If you look at the estimated cost of poisoning from pesticide (杀虫剂) in sub-Saharan Africa, only the injury and the loss of working time is estimated to be 6.3 billion US dollars in 2009. This is higher than the total ODA that is going to the health part in the same area.”

The UNEP estimates that chemical sales worldwide will increase by around three percent a year until 2050. Chemical production is moving quickly from developed to developing countries. By 2020, chemical production is expected to increase by 40 percent in Africa and the Middle East and 33 percent in Latin America. One of its biggest concerns is pollution of rivers and lakes by pesticide and fertilizer. Other major concerns are heavy metal pollution from the production of cement (水泥) and textiles (纺织品), and dioxin pollution from mining.

The UN report urges the chemical industry and governments to work together to develop safety policies. It says preventing harm costs less than fixing it.

1. The purpose of Paragraph 3 is mainly to indicate that ______.

A．chemicals have a high production cost

B．Africa needs more development aid

C．the use of pesticide causes a great loss

D．the estimated cost of poisoning from pesticide is incorrect

2. Which of the following is NOT a source of danger according to the text?

A．Pesticide.	B．Fertilizer.
C．Heavy metals.	D．Minerals.

3. According to the text, what is the main reason for the risks from chemicals?

A．The mass production of cement and textiles.

B．Lack of research funds on chemicals.

C．Poor management of chemicals.

D．Contradictions between chemical producers and governments.

4. What would be the best title for the text?

A．The truth in Sylvie Lemmet’s comments

B．A UN warning about chemical dangers

C．The unpredictable future of chemical industry

D．Preventing is much better than fixing

10 . Each year, about 7 million tons of trash (垃圾) is found in the ocean. This trash consists of cigarette ends, medical waste, plastic, mile-long nets, etc... Those items of trash choke (窒息) many species of ocean life so quickly that they eventually become extinct. Ocean pollution harms the earth and animals, and we should stop the problem.

Some other causes of ocean pollution are waste, poisonous chemicals, and the biggest cause is littering (乱丢垃圾). How do these items end up in the ocean? Waste flows through rivers and drains (下水道) directly to the ocean, so ocean pollution continues to step up. The estimated amount of ocean pollution that floated in the sea in 2012 was 288 million tons. This huge number continues to increase by 4% each year. That means 11, 520, 000 tons of trash increase each year. Imagine the future of our ocean. Will there be any room to swim? Also 80% of the ocean is composed of plastic: plastic bottles, plastic bags, and some plastic toys.

How can ocean pollution be solved? Use fabric bags instead of plastic bags. This would reduce the plastic pollution in the ocean. Also for the waste water problem, we could use waste water treatment system. Lastly using renewable energy sources such as wind power or solar power would limit offshore drilling.

If we don’t stop the causes of ocean pollution, water temperatures will continue to rise and ocean life will become endangered. Please be mindful that what we do affects the people around us, the animals around us, and the habitats around us. So will you pay attention to this problem or wait for the next generation to?

1. What leads to the ocean pollution worst?

A．Cigarette ends.	B．Littering.
C．Medical waste.	D．Plastic.
