广东省高考真题英语参考答案(2)
(B)
Care for a zoom-in observation of animals with no bars between you and the observed opposed to ordinary zoos? Where to have close-up encounters with some of the world’s most rare animals.? We are revealing for you:
1. Right whales, Bay of Fundy, Canada
Northern right whales are on the brink of extinction, but survivors arrive in the Bay of Fundy each summer (May through October) to feed east of Grand Manan Island. They are recognized by a broad back and no dorsal fin, which distinguish them from other whales entering the bay.
Planning: Whale-watching tours operate out of Digby
Neck peninsula on Nova Scotia and nearby islands, such as Brier Island, St. Andrews, Grand Manan Island, and Deer Island.
2. Grizzly bears, Alaska
Grizzlies like salmon. In mid-July and again in mid-August, grizzlies make for Alaskan rivers to hook out the fish with their formidable claws. The bears gather in large numbers at rapids and pools, sometimes fighting for the best sites. Brooks Falls in Katmai National Park, and Fish Creek, near Hyder, have viewing platforms.
Planning: Most fishing sites are accessed by chartered light aircraft and a hike. Hyder is off the Stewart-Cassiar Highway.
3. Monarch butterflies, Sierra Chincua, Mexico
Each fall, millions of North American monarch butterflies migrate thousands of miles to the oyamel fir forests of the Transvolcanic Mountain Range, in the state of Michoacán. They flock intimately on tree trunks, bushes, and on the ground, fully showing their gregariousnature and occupy Sierra Chincua and four neighboring hills that make up the Monarch Butterfly Biosphere Reserve.
Planning: Chincua is one of two hills in the reserve open to the public from November through March.
4. Komodo dragons, Komodo Island, Indonesia
Landing on Komodo, you would feel like stepping back to a time when dinosaurs ruled the Earth, as park maps reported, “Here be dragons!” This mountainous volcanic island is home to the world’s largest living lizard—the Komodo dragon. Weighing 79 to 91 kg, the Komodo dragon has a tail as long as its body. You can hike to a viewpoint at Banugulung and watch as park rangers feed food to the lizards, some of which are more than 10 ft (3 m) long.
Planning: Komodo is reached solely by boat from Bima (on eastern Sumbawa) or Labuan Bajo (on western Flores).
5. Wildebeest migration, Serengeti, Tanzania

(C)
Genetic testing offers people insight into the types of diseases they are most likely to develop — but a new study suggests most people do not alter their lifestyles based on this
information. These tests — known as genome sequencing — analyze a person's DNA, telling patients about their known risk for diseases like cancer or diabetes. But being told you’re at a higher risk for lung cancer doesn’t seem to motivate anyone to quit smoking or alcohol, this study suggests. Because of this, the scholars argue that genetic testing should be banned as a tool for improving people's health.
Today’s finding came from pulling data from 18 other studies that followed people after they received the results of genetic tests. Receiving information about genetic risks didn’t inspire people to eat differently, exercise more, or stop smoking, "Expectations have been high that giving people information about their genetic risk will empower them to change their behavior, but we have found no evidence that this is the case," study author Theresa Marteau, director of behavior and health research said in a press release.
Genetic testing, which the National Institutes of Health says costs anywhere from $100 to $2,000, has become much more accessible as commercial testing companies such as 23andMe and Sure Genomics have sprung up. These companies are not allowed to share
disease risk estimates with consumers thanks to the Food and Drug Administration. However, today’s study didn’t specify whether the genetic testing were purely from academic sequencing, or if any of these companies had had a role in supplying the data.
