题目内容

Elephants might be the most well-known and well-loved animal in African wildlife. But conservation (保护) of the African elephant faces special difficulties. While the elephant population is half of what it was 40 years ago, some areas of Africa have more elephants than populated areas can support. That’s why AWF scientists are studying elephant behavior, protecting habitats and finding ways for humans to live peacefully with elephants in Africa.

Years ago, over hunting and the ivory trade were the biggest threats to elephants survival. Luckily, ivory bans (禁令), hunting rules and protected areas protect elephants from these dangers today.

The 21st century brings a different challenge to elephant conservation —land-use. Elephants walk across borders and outside parks and other protected areas. So they often destroy crops, causing conflicts (冲突) between local farmers and these big animals.

Successful conservation strategies (策略) must allow elephants to walk freely in their natural habitats while reducing conflicts between elephants and local people.

AWF researchers are searching for a way to give both elephants and people the space they need. The AWF is collecting information on elephant habitats and behavior. The information they gather will help to develop the widest possible space for elephants.

The AWF is helping elephants by protecting their habitats. And they also work with local farmers to improve their life in order to encourage them to protect rather than destroy elephants.

1.The first paragraph of the text is mainly to tell readers _____.

A. African elephants are endangered now

B. there remains a lot to do to protect African elephants

C. African elephants are popular animals

D. the number of African elephants has increased over the years

2.What is the biggest difficulty in protecting African elephants now?

A. They are still being killed.

B. Their habitats are being destroyed.

C. They don’t have enough food.

D. They can’t live in peace with farmers.

3.To protect elephants, the AWF does all the following EXCEPT _____.

A. keeping elephants

B. protecting elephants’ habitats

C. doing research on elephants

D. helping farmers improve their life

4.What is the best title for the text?

A. African elephants conservation

B. Living with African elephants

C. African elephants’ situation

D. African elephants being endangered

Dear Sir,

I have to travel every day from Souk Road to the airport. Two buses travel along their route: the number 49 and number 16. But by the time the number 16 bus reaches Souk Road it is always full, so I can’t get on it. I have to wait for the number 49, because sometimes there are empty seats on it.

The timetable says that there are buses from Souk Road to the airport every ten minutes. If this is so, why do I have to wait half an hour for a bus nearly every day?

The regulations (规章) say that if there are empty seats on a bus, the bus must stop at every stop where people are waiting. Why do the half-empty buses go straight past me when I am standing at the bus stop?

The regulations say that no bus may carry more than 40 seated passengers and 20 standing passengers. Yesterday I was the first to get off the bus when it reached the airport. I counted the other passengers as they got off. There were 129 of them.

It is clear that our bus companies break the regulations and think little of their passengers. Can nothing be done to make your service better?

Yours,

Tired passenger

1.The writer has to take Bus No. 49 because______.

A. a bus driver

B. an airport worker

With global warming and melting ice, it isn’t easy being a polar bear anymore. Some studies have predicted that polar bears could die out by the end of the century. The good news is not all researchers think the bears are absolutely disappearing. Scientists at the American Museum of Natural History(AMNH) have published a new paper indicating that things might not be as bad for polar bears as some scientists expect.

To understand the reason for the researchers’ cautious optimism, we must first understand the factors that are threatening the polar bear’s existence. Polar bears consume a diet of mainly young seals. In order to hunt these seals, polar bears need to rest at the top of sea ice---the same ice that is increasingly melting for most of the year thanks to climate change. In another 50 years, experts expect that the Arctic will be too warm for sea ice to form for half of the year, leaving polar bears without a reliable food source and in serious danger of starvation.

As it turns out, alternative food sources for the polar bears aren’t completely out of the question. For as long as biologists have tailed after the animals, they’ve seen polar bears eating animals found on land like caribou(驯鹿) and snow geese---as well as the snow geese’s eggs.

Can polar bears actually survive off these alternative food sources for long periods of time? To figure this out, researchers calculated the nutrients that a caribou and snow geese diet would provide. They found that even adult male polar bears would be able to obtain more calories than would burn in hunting these meals. Moreover, the food would provide the food lecessary to avoid starvation during the summer months.

Unfortunately, not all polar bears have tended to seek food on land. That said, the researchers expect that necessity would push more polar bears to hunt on land to avoid starvation. They also expect that the bears could learn from their fellow bears how to hunt on land until the practice becomes second nature.

America’s holiday shopping season started on Black Friday, the day after Thanksgiving.

1. Shoppers make the most money this time of year, about 20 percent to 30 percent of all revenue all year. About 136 million people shopped during the Thanksgiving Holiday weekend.

2. In an era of instant information, shoppers can use their mobile phones to find deals. Nearly 80 percent of this year’s holiday shoppers, or about 183.8 million people, shopped on Cyber Monday. 3. Online spending on Black Friday rose 15 percent to hit $2.7 billion this year. Cyber Monday spending increased 12 percent to $3 billion. NBC News reported that for many, shopping online was a more comfortable alternative than crowded malls.

The shift to online shopping has had a big impact on solid shopping malls. Since 2010, more than 24 shopping malls have closed and an additional 60 are struggling. Fortune says the weakest of the malls have closed. However, the business in malls is thriving again, it adds. According to a survey, 94.2percent of malls were full with shops by the end of 2014. 4.

The average American consumer will spend about $805 on gifts. That’s about $630.5 billion between November and December – an increase of 3.7 percent from last year.

5. That goes to China’s Singles’ Day, celebrated on November 11, which posted record sales of $14.3 billion in 2015.

A．More and more people shop online nowadays.

B．That is the highest level in 27 years.

C．It is the busiest shopping day of the year.

D．One-in-five Americans used a tablet or smart-phone.

E．The traditional mall industry can hardly survive.

F．Cyber Monday falls on the Monday after Thanksgiving and Black Friday.

G．Nonetheless, Cyber Monday is not the biggest online shopping day in the world.

Are we getting more stupid? According to Gerald Crabtree, a scientist at Stanford University in the US, we are. You may not want to hear this, but Crabtree believes that human intelligence reached its peak more than 2,000 years ago and ever since then has been going downhill. “If an average Greek from 1,000 BC were transported to modern times, he or she would be one of the brightest among us,” Crabtree told The Guardian.

At the heart of Crabtree’s thinking is a simple idea. In the past, intelligence was critical for survival when our ancestors had to avoid dangerous animals and hunt for food. The difference of being smart or stupid is often life or death. However, after the spread of agriculture, when our ancestors began to live in dense ( 稠密的）farming communities, the need to keep their intelligence in peak condition gradually reduced. This is not hard to understand. Most of the time,pressure is what keeps us going – you need the pressure from your teachers to finish your homework; the pressure of looking pretty prompts(促使) you to lose weight when summer comes. And the same is also true of our intelligence – if we think less, we become less smart.

These mutations(变) are harmful to our intelligence and they were all developed in the past 3,000 years. The other evidence that Crabtree holds is in our genes. He found that among the 2,000 to 5,000 genes that we have that determine human intelligence , there are two or more mutations in each of us. However, Crabtree’s theory has been criticized by some who say that early humans may have better hunting and surviving abilities, but people today have developed a more diverse intelligence. For example, spearing a tiger doesn’t necessarily require more brainpower than playing chess or writing a poem. Moreover, the power of modern education means a lot more people have the opportunity to learn nowadays. “You wouldn’t get Stephen Hawking 2,000 years ago. He just wouldn’t exist,” Thomas Hills of the University of Warwick, UK, told Live Science. “But now we have people of his intellectual capacity doing things and making insights(洞察力) that we would never have achieved in our environment of evolutionary adaptation.”

1.What is Crabtree’s recent finding according to the article?

A. The Greeks from 1,000 BC could have been the smartest in human history.

B. Our ancient ancestors had no better surviving abilities than we do nowadays.

C. Humans have been getting steadily more intelligent since the invention of farming.

D. Mutations in genes that decide human intelligence have affected the development of intelligence.

2.According to Crabtree, ancient humans _______.

A. had many more genes that determine human intelligence

B. were forced to be smart due to natural selection pressures

C. relied more on group intelligence than individual intelligence

D. developed a diverse intelligence to adapt to the hard realities

3.Some argue that Crabtree’s theory is false because they think _______.

A. people today are under much more pressure than early humans

B. it’s ridiculous to compare a hunter’s and a poet’s intelligence

C. modern education is far more advanced than ancient education

D. human intelligence nowadays is different from that of the distant past

4.What is Thomas Hills’ attitude toward Crabtree’s theory?

A. Supportive B. Unfavorable

C. Worried D. Confused
