高三英语单项填空简单题查看答案及解析

We are interested in the preservation of the biodiversity on Earth. What I’ve been working on is rats. Just looking at rats, you can understand continental drift and climate change. We’ve actually rediscovered rats that were thought to be extinct. Darwin was the last one to document them on the Galapagos Islands. People have gone there for hundreds of years and not seen one. In 1997, I went there with my mentor(导师) and another graduate student. Everyone thought I was crazy, why look for something that doesn’t exist? They wouldn’t even give us permits. Our plan was to stop on a beach for a day and then hike up to the top of an extinct volcano where very few people had been:We were on a picturesque, isolated beach. We set out the traps just to see what we might find. The next morning, I checked my traps! I immediately ran back to my mentor. When he looked in the mental trap—I will never forget his face--- It looked like he’d seen a ghost.

I certainly understand the argument: “ Who cares about an extinct rat?” but you have no idea what role that rat plays in that functioning ecosystem. People can appreciate beauty, so that’s why people love pandas and want to keep them around. You never hear, “What good is panda?” Ecologically, these rats are much more important to their ecosystem than those pandas--- not that I don’t love pandas but we have to look beyond the big and beautiful.

I teach conservation biology and evolution. In both you have to appeal to people asking “ Why is this important to me?” Some scientists refuse to do that. That’s my entire approach. I’ll ask “How many of you had a family member who was in a tornado, hurricane or flood?” .And almost every hand goes up. Climate change is suddenly very personal, and now they want to hear what you are saying. You are not looking for sympathy for the rats but for a greater understanding of the system.

Ninety percent of Americans drive to work every day although working from home is on the rise. If you’re lacking for topics of conversation at a party, chatting about your commute is a pretty safe bet.

According to a recent study, driving for more than two hours each day can steadily decrease the IQ of middle aged drivers. The Sunday Times of London detailed the study, which looked into the lifestyle choices of over 500,000 Britons between the ages of 37 and 73.

When looking at the data of the 93,000 participants who drove more than two to three hours per day, the study found a noticeable dropoff in brainpower, measured by intelligence and memory tests. The study found similar results with participants who took part in several hours similarly sedentary (久坐的) activity, like television watching.

As it turns out, stimulating activity stimulates your brain, while non-stimulating activity, well, doesn’t stimulate your brain.

“Cognitive (认知的) decline is measurable over five years because it can happen fast in middle-aged and older people. This is associated with lifestyle factors such as smoking and bad diet — and now with time spent driving,” Kishran Bakrania, a medical epidemiologist at the University of Leicester told the Times.

Fortunately for most Americans, the average commute time was recorded at approximately 26.5 minutes according to the 2015 United States Census.

And if you think that the way to pump up your IQ is through brain games, think again. Just try and avoid those long hours on the road if possible, and if you happen to have free time on your commute, be sure to use it wisely.

1.According to the passage, which of the following may be of help to our brainpower?

A. Watching TV.　　 B. Having sports.

C. Driving long time.　　 D. Sleeping.

2.Why does the writer mention “results with people participating in similarly sedentary activities” in para 3?

A. To make a contrast.　　 B. To give an example.

C. To make a description.　　 D. To give more evidence.

3.We can infer from the passage that ________.

A. long time drive may decrease the driver’s IQ

B. smoking and bad diet can cause cognitive decline

C. people should participate in more stimulating activities

D. an increasing number of Americans drive to work every day
