4 . Though my friend and I have had our own careers in different cities, we still get together, like, once a month to chat and________.

5 . 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。

As artificial intelligence products steadily improve at pretending to be human, people will increasingly be put in the unsettling situation of not knowing     1     they are talking to a machine. But the     2     (true) may make such products less effective: recent research finds a trade-off between transparency and cooperation in human-computer interactions.

The study used a game in     3     paired players made a series of     4     (decision) to cooperate with betray their partner. In     5     long run, it pays for both to keep cooperating. But there is always the desire     6    (earn) extra points at the partner’s expense. Previous work suggested people tended to distrust machines, so the scientists hoped people     7     (play) with a known robot would recognize its ability to cooperate and would     8     (eventual) get past their distrust.

“Sadly, we failed at this goal,” says Talal Rahwan, a senior author on the paper,     9     (publish) last November in Nature Machine Intelligence. “A robot was     10     (likely) to obtain cooperation than another human, even though its strategy was clearly more beneficial to both players.”

It seems that there is a long way to go before trust in robots is established.

7 . The daily life can be busy and at times difficult. It may sometimes feel like bringing just a little more inner peace and calmness into your life is a hopeless wish.     1     Small and smart changes can make a big difference over time. Here are some tips for finding more peace and calmness in everyday life.

Set limits (限制). If your life is overfilled, you may need to set some limits. So stop doing some of the least important things, which honestly don’t matter that much. Set a limit for how many times you will check your mailbox, Instagram,Twitter etc. per day.     2    

Organise your world and your mind.     3     A tidy, clean and ordered space around you brings clarity and order to the mind. So don’t stop there. Simplify and organise your home and life to live in a more relaxing environment.

    4     Reading minds is pretty much impossible. But still we often try it and create anxiety and uncertainty for ourselves. So ask and communicate instead. It may sometimes be a bit hard at first but it can save you and the people around you so much trouble in the long run.

Solve a problem that is weighing heavily on you. Solve your problem and release (释放) all the stress that it is creating in your life. You probably already know what to do, and you are just not doing it yet.     5     So get up from your chair and get started right now.
