1 . Long long ago, there was an old man who lived with his son, his daughter-in-law, and a four-year-old grandson. The old man’s hands trembled(颤抖), his eyesight was very poor, and he couldn’t walk steadily (平稳地). The family ate together nightly at the dinner table. But the elderly grandfather’s shaky hands and failing sight made eating rather difficult. Rice often dropped on the floor.
The son and the daughter-in-law became angry with the old man, so they put a small table in the corner. There, the grandfather ate alone, while the rest of the family enjoyed dinner at the table. Since the grandfather had broken a dish or two, his food was served in a wooden bowl.
The four-year-old son watched it all in silence. One evening before supper, the father noticed his son playing with a piece of wood on the floor. He asked the child sweetly, “What are you making?” The boy answered, “Oh, I am making a little bowl for you and mama to eat your food from when I grow up.” The four-year-old son smiled and went back to work. The words struck the parents so hard that they were in silence. Then tears started to stream down their cheeks (脸颊). Though no word was spoken, both knew what must be done. That evening the husband took grandfather’s hand and gently led him back to the family table.

3 . People have grown taller over the last century,with South Korean women shooting up by more than 20 cm on average, and Iranian men gaining 16.5 cm. A global study looked at the average height of 18-year-olds in 200 countries between 1914 and 2014. The results show that while Swedes were the tallest people in the world in 1914.
Dutch men have risen from 12th place to the top spot with an average height of 182.5 cm. Latvian women, meanwhile, rose from 28th place in 1914 to become the tallest in the world a century later,with an average height of 169.8 cm.
A little extra height brings a number of advantages says Elio Riboli of Imperial College."Being taller is associated with longer life expectancy,"he said."This is largely due to a lower risk of dying of cardiovascular(心血管的)disease among taller people."
But while height has increased around the world, the trend in many African countries causes concern, says Riboli.While height increased in Uganda and Niger during the early 20th century, the trend has reversed(反转) in recent years, with height decreasing among 18-year-olds.
“One reason for these decreases in height is the economic situation in the 1980s,” said Alexander Moradi of the University of Sussex. The nutritional and health crises led to many children and teenagers failing to reach their potential height.
James Bentham, a co-author of the research from Imperial College, believes the global trend of increasing height is of great importance. “How tall we are now is strongly influenced by the environment we grew up in," he said. "If we give children the best possible start in life now, they will be healthier and more productive for decades to come.”

7 . To help self-driving cars drive safely, scientists are looking to an unlikely place: the sea. A new type of camera inspired by the eyes of mantis shrimps(螳螂虾) could help autonomous vehicles better assess their surroundings, researchers report October 11 in Optica. The camera has roughly half a million sensors that each capture a wide range of light and dark spots within a single frame, somewhat similar to how mantis shrimps see the world.
The researchers wanted to ''imitate the animals' ability to detect a wide range of light intensities(强度), ''says co-author Viktor Gruev, a bio-engineer at the University of Illinois at Urbana-Champaign. The shrimps’ visual system allows them to see both light and dark areas while moving in and out of dark cracks in shallow waters, he says.
The newly devised camera can take in a wider range of light intensities, measured in decibels (分贝), than other digital or polarization cameras. Previously, the best polarization cameras operated with a dynamic range of about 60 decibels; the new one works within a 140 decibel range, resulting in a clearer mapping of objects in the same frame.
Depending on the maker, autonomous vehicles currently use a mixture of methods to map the world around them, including lidar (light detection and ranging equipment), cameras and GPS. But the cameras currently guiding autonomous vehicles aren't good at handling sharp lighting transitions and have trouble detecting features in foggy weather. Because the new cameras are small and use many of the same parts as common digital cameras, Gruev says they could cost as little as $10, which means they are car-makers' best choice for their autonomous vehicles.
1. What do we know about the new cameras after reading the article?A.They enable cars to go through cracks without trouble. |
B.They use totally different parts from common cameras. |
C.They have already been widely used on self-driving cars. |
D.They see the surroundings by detecting the light intensities. |

9 . Babies made from three people approved in UK
Babies made from two women and one man have been approved by the UK’s fertility regulator. The historic and controversial move is to prevent children from being born with deadly genetic diseases.
Doctors in Newcastle — who developed the advanced form of In Vitro Fertilization or IVF (人工授精) — are expected to be the first to offer the procedure and have already appealed for donor eggs. The first such child could be born, at the earliest, by the end of 2017.
Some families have lost multiple children to incurable mitochondrial (线粒体的) diseases, which can leave people with insufficient energy to keep their heart beating.
The diseases are passed down from only the mother, so a technique using a donor egg as well as the mother’s egg and father’s sperm has been developed.
The resulting child has a tiny amount of their DNA from the donor, but the procedure is legal and reviews say it is ethical (伦理的) and scientifically ready.
“It is a decision of historic importance,” said Sally Cheshire, chairwoman of the Human Fertilisation and Embryology Authority (HFEA). “I’m sure patients will be really pleased by what we’ve decided today.”
But some scientists have questioned the ethics of the technique, saying it could open the door to genetically-modified(转基因) ‘designer’ babies.
The HFEA must approve every clinic and every patient before the procedure can take place. Three-person babies have been allowed only in cases where the risk of a child developing mitochondrial disease is very high.
Prof Mary Herbert, from the Newcastle Fertility Centre, said, “It is enormously pleasing that our many years of research in this area can finally be applied to help families affected by these devastating diseases”.
“Now that we are moving forward towards clinical treatments, we will also need donors to donate eggs for use in treatment to prevent affected women transmitting disease to their children.”
Prof Sir Doug Turnbull, the director of the Welcome Centre for Mitochondrial Research at Newcastle University, said, “We are delighted by today’s decision. We will also provide long-term follow up of any children born.”
NHS England has agreed to fund the treatment costs of the first trial of three-person IVF for those women who meet the HFEA criteria, as long as they agree to long-term follow up of their children after they are born.
