Sir David Attenborough is set to host a brand new natural history series, named A Perfect Planet. The noted documentarian is back, and will be starring in a five-part BBC One series which will take a look at “the intricate（复杂）systems” that allow Earth to boom.
The show is set to explain how the planet operates, looking at everything from ocean currents to solar energy to the weather, and risking all around the world, from India to the Arctic.
Plus, in showing how the earth works, the documentary will also seek to display how animals adapt to their natural environments as they continue to change. As ever, it sounds like a truly fantastic watch.
It won’t be a surprise to hear that the new Attenborough series is set to feature some wonderful film scenes, too.
Speaking of the brand new series, from Our Planet producers Silverback Films, Sir David said: “Oceans，sunlight, weather and volcanoes - together these powerful yet fragile forces allow life to flourish（茂盛）in astonishing diversity. They make Earth truly unique-a perfect planet. Our planet is one in a billion, a world filled with life. But now, a new determining force is changing the face of Earth: humans. To preserve our perfect planet we must ensure we become a force for good.”
While an exact first-show date has not yet been announced, the show is set to land on BBC One later this year.

As the climate warms, birds are shrinking and their wingspans are growing, according to a new study. Researchers analyzed 70,716 birds from 52 kinds of North American migratory（迁徙的）bird species collected over 40 years. The authors say the study is the largest of its kind and that the findings are important to understanding how animals will adapt to climate change.
\found almost all of the species were getting smaller.\said lead author Brian Weeks, an assistant professor at the University of Michigan.
\consistency was shocking.\
He said studies of animal responses to climate change often focus on shifts in geographical range or timing of life events, like migration and birth. But this study suggests body morphology（形态）is a crucial third aspect.
\one major implication,\he said, \hard to understand how birds will adapt without taking all three of these things into consideration.\
The findings showed that from 1978 to 2016, the length of the birds' lower leg bone shortened by 2.4%. Over the same time, the wings lengthened by 1.3%.
The evidence suggests warming temperatures caused the decrease in body size, which in turn caused the increase in wing length.
\is an incredibly taxing thing they do,\Mr. Weeks said, explaining that the smaller body size means less energy available for the birds to complete their long journeys.
He says the birds most likely to survive migration were the ones with longer wingspans and smaller bodies.
The scientists aren't exactly sure why warmer temperatures cause birds to shrink. One theory is that smaller animals are better at cooling off, losing body heat more quickly. 28．What's the best title for the text?

When you are sitting in the car, do you ever notice the drivers looking over their shoulders or side to side in the car? Well, they are doing this to check their blind spots! Blind spots take driving extremely difficult and increase the potential for car accidents.
Fourteen-year-old Alaina Gassler from Pennsylvania noticed her mother struggling with blind spots while driving their family car. So she came up with an ingenious solution that won the first place and $25,000 in the Broadcom Masters Competition.
Blind spots are the areas around the car that cannot be directly observed by the driver. There are two kinds of blind spots---on the back of the car that cannot be seen with mirrors, and blind spots at the front of the car as well.
When a driver is changing lanes, he has to look over his shoulder through the side windows to make sure that there is no vehicle in the blind spot. This invisible area is big enough
to hide a car!
The other blind spot is created in the front by the A-pillar（柱子）---the material on either side on the windshield（挡风玻璃）that holds the glass and forms the frame of the car. In some cars, this pillar can be quite thick. Usually, people or cyclists can be hidden by this pillar.
Alaina's design was to get rid of the blind spot created by the front A-pillar of the car, the one that helps hold up the windshield.
She put a camera on the outside passenger side of the car which then sent the photos to a projector above the drivers' head. Then, she covered the inside of the pillar in reflective fabric onto which the image was projected. Basically, her device made the pillar \
Alnina's solution is very creative and could be improved by using LCD displays that will make it easier to see during day time as well. 32．What can be learned about blind spots during driving? A．They call for careful driving. C．They are many in kinds.
B．They make driving thrilling. D．They can't be get rid of.
33．Which of the following can replace the underlined word \A．interesting C．inspiring
34．How did Alaina solve the problem? A．By improving the A-pillar. C．By relying on LCD displays.
B．By using a mirror on the outside of the A-pillar. D．By using a camera to capture images. B．creative D．invisible
