【题目】Scientists are fond of running the evolutionary clock backward, using DNA analysis and the fossil record to figure out when our ancestors stood straight and split off from the rest of the primate evolutionary tree. But the clock is running forward as well. So where are humans headed? Here's a thoughtless assessment of possible paths, ranging from similar humans to alien-looking hybrids bred for interstellar (星际的) travel.

Different populations of a species have to be separated from each other in order for those populations to diverge into separate species. Populations are increasingly in contact with each other, leading to greater gene-mixing. It's believable that separate species would appear. Evolution is still at work and the trend may well be accelerating. Cultural diversity is fading as human society becomes more interconnected globally.

The radical king of evolution moves much more quickly than biological evolution. High-tech improvements are ranging from Supermen, to camera-equipped flying drones(遥控飞机), to pills that keep soldiers going without sleep or food for days. To date, genetic medicine has focused on therapies that work on only one person at a time. The effects of those therapies aren't carried on to future generations. Tinkering with the germline could conceivably produce a superhuman species in a single generation-but could also conceivably create a race of monsters.

Today the rapid pace of cybernetic(计算机控制论的) change has led to worry that artificial intelligence may outpace human’s natural smarts. In some fields, artificial intelligence has already bested human. We're already making machines that can be assimilated (同化) including artificial limbs, mechanical hearts, and artificial retinas (视网膜).

If humans survive long enough, there's one sure way to grow new branches on our evolutionary family tree by spreading out to other planets. If humans established a permanent settlement on other planets, the radically different living conditions would change the evolutionary equation (方程式) What will be inconceivable millions of years from now? Two intelligent species, human and machine, definitely work together to spread life through the universe.

【1】Scientists study the evolution according to .

A. different populations of a species

B. Humans spread out to other planets.

C. Human and machine work together.

D. Living conditions change the evolutionary equation.

【题目】One day, when I was working as a psychologist in England, an adolescent boy showed up in my office. It was David. He kept walking up and down restlessly, his face pale, and his hands shaking slightly. His head teacher had referred him to me. "This boy has lost his family," he wrote. "He is understandably very sad and refuses to talk to others, and I'm very worried about him. Can you help?"

I looked at David and showed him to a chair. How could I help him? There are problems psychology doesn't have the answer to, and which no words can describe. Sometimes the best thing one can do is to listen openly and sympathetically.

The first two times we met David didn't say a word. He sat there, only looking up to look at the childrens drawings on the wall behind me. I suggested we play a game of chess. He nodded. After that he played chess with me every Wednesday afternoon - in complete silence and without looking at me. It's not easy to cheat in chess, but I admit I made sure David won once or twice.

Usually, he arrived earlier than agreed, took the chess board and pieces from the shelf and began setting them up before I even got a chance to sit down. It seemed as if he enjoyed my company. But why did he never look at me?

"Perhaps he simply needs someone to share his pain with," I thought. "Perhaps he senses that I respect his suffering." Some months later, when we were playing chess, he looked up at me suddenly.

"It's your turn," he said.

After that day, David started talking. He got friends in school and joined a bicycle club. He wrote to me a few times about his biking with some friends, and about his plan to get into university. Now he had really started to live his own life.

Maybe I gave David something. But I also learned that one - without any words can reach out to another person. All it takes is a hug, a shoulder to cry on, a friendly touch, and an ear that listens.

【1】【改编】 Without any words,which can reach out to another person?

A.a hug

B.a smile

C.a song

D.a gift

【2】【改编】 What can be inferred about David?

A. He recovered after months of treatment.

B. He liked biking before he lost his family.

C. He went into university soon after starting to talk.

D. He got friends in school before he met the author.

【3】【改编】What made David change?

A. His teacher's help.

B. The author's friendship.

C. His exchange of letters with the author.

D. The author's silent communication with him.
