“The dangerous thing about lying is people don’t understand how the act changes us,” says Dan Ariely, behavioural psychologist at Duke University. Psychologists have documented children lying as early as the age of two. Lying is even considered     1     developmental milestone, like crawling and walking, with sophisticated planning and attention     2     (require). But, for most people, lying gets increasingly limited as we develop a sense of morality and the ability to self-regulate.

According to Ariely, lying takes work. In studies, he gave subjects a chance to deceive for monetary gains while examining their brains in a functional MRI machine. Some people told the truth instantly. But others opted to lie, and they showed increased activity in their frontal parietal(颅腔壁的)control network, which is involved in complex thinking. It suggested that they were deciding between truth and dishonesty, and after thinking about it,     3     (choose) the latter. For a follow-up analysis, he found that people whose neural(神经的)reward centers were     4     (active) when they won money were less likely to be among the group of liars, and the opposite was seen among those so-called habitual liars, suggesting that lying     5     have to do with the inability to resist temptation.

External conditions also matter in terms of when and how often we lie. We are more likely to lie, research shows, when we see others being dishonest. And we are less likely to lie when we think others are watching. “We     6     a society need to understand that, when we don’t punish lying, we increase the probability of     7     happening again, influencing all of us,” Ariely said.

In a 2016 study, Ariely and colleagues showed how dishonesty alters people’s brains, making it easier to tell lies in the future. When people told a lie, the scientists noticed a burst of activity in their amygdala, a crucial part of the brain that produces fear and guilt. But when scientists had their subjects     8     (play) a game in which they won money by deceiving their partner, they noticed the negative signals from the amygdala began to decrease. “Not only that,” said Ariely in an interview with National Science Channel, “     9     people tended to lie more when they faced no consequences for dishonesty. This means that if you give people multiple opportunities to lie for their own benefit, they start with little lies,     10     get bigger over time.”

China plans to complete the construction of a space station and have    1    put into operation around 2022, said Zhou Jianping, the chief designer of China's manned space program, at a forum (论坛)    2    (hold) in south China's Guangdong Province. The space station,    3    could be enlarged if needed,    4    (design) to weigh 100 tonnes and accommodate three astronauts, according to Zhou.

“The main goal of the construction or the space station is to enable China to become a country    5    (independent) mastering the technology for long term manned flight in near Earth space, and having the capacity to carry out long-term manned scientific    6     (experiment) in near Earth space and comprehensive development and utilization (利用) of space resources,"    7    (say) Zhou at the 4^th China Summit Forum on Human Factors Engineering, which was held at SunYat-sen University from Saturday to Sunday.

The space station will be built as China’s main platform for space science research    8    the intention of mastering the technologies in constructing and    9    (operate) large space facilities, the technologies that guarantee life and health of astronauts who often fly in orbit, and the construction of a    10    (nation) space lab, according to Zhou.

Up to 82 percent of children with healthy mothers are not easy to be obese（肥胖的）, according to research. A mother,     1     has a healthy weight, exercises regularly, eats a healthy diet, doesn’t smoke and only     2    (drink) wine in moderation, is significantly less likely     3    (have)a fat child, scientists say.

When both mother and child follow a healthy lifestyle, the risk of obesity     6    (reduce)even more, the study of more than 24,000 children found.

The study examined the medical history and lifestyles of more than 24,000 children aged nine     7     fourteen, born to almost 17,000 women in the US. Researchers looked at the link between overall mother health and likelihood of a child     8    (be) obese.

The mother's health was judged on her height-to-weight ratio(比例), her diet, amount of physical     9    (active), smoking status and how much alcohol she drank. A healthy weight and diet, regular exercise, no smoking and moderate drinking all reduce the chance of a woman having     10     obese child.
