The secret lies in artificial intelligence (AI). Since 2022, big prgress in generative (生成式) AI has pushed humanid rbts t the next level. Nw, cmpanies are cming up with amazing technlgies like large language mdels (LLMs).
Peter Chen frm Cvariant tld the Ecnmist that LLMs, which pwer ChatGPT, can be used t imprve rbtics. LLMs learn frm tns f data and use that knwledge t help rbts think. Visual AI helps rbts understand what they see in phts and vides. This mix f LLMs and visual AI allws rbts t knw hw things relate and interact, imprving their ability t mve and perfrm tasks.
But being smart isn’t enugh—rbts als need t mve well. In the past, even simple tasks like picking up an apple were hard fr rbts. These days, new technlgy makes them better. Using light materials like carbn fiber (碳纤维) makes rbts strng and flexible. While sensrs let them see, hear and “feel” their envirnment, mtrs help them mve easily.
Take Unitree Rbtics’ H1 humanid rbt as an example. It has a 3D LiDAR sensr, a depth camera and a pwerful M107 jint (关节) mtr.
Humanid rbts are n the rise. The market fr these rbts culd be wrth 276.9 billin yuan by 2035.

B．T explain hw humanid rbts interact with humans.
C．T ffer sme tips fr training a humanid rbt.
D．T shw hw technlgy helps rbts mve better.

The drnes perate day and night, cvering large areas mre efficiently than human-led clean-up effrts.
Traditinal clean-up methds invlve ships and nets, which are slw, expensive, and ften harm marine life. The drnes, hwever, are designed t avid wildlife while targeting nly plastic waste. Early trials shw they can cllect up t 100 kilgrams f debris per day, making them a prmising slutin fr large-scale cean clean-up.
One challenge is that strng cean currents can push debris ut f reach, making it harder fr the drnes t perate effectively. Dr. Hannah Lee, the prject crdinatr, says her team is imprving the drnes’ navigatin systems t handle rugh sea cnditins. They are als develping ways t recycle the cllected plastic int usable materials.
If successful, these drnes culd play a key rle in restring marine ecsystems and prtecting sea life. This technlgy ffers hpe fr a cleaner, healthier cean in the future.
41．Hw d the drnes identify plastic waste in the cean?

42．Why are drnes better than traditinal clean-up methds?

43．Hw much debris can each drne cllect daily?

44．What prblem d strng cean currents cause fr the drnes?

45．What aspect f the drnes is Dr. Lee’s team imprving?

46．Explain hw cean-cleaning drnes help marine life. (不超过30个词)

参考答案
1．century/entury
【详解】句意：我已经回到英国三天了，但感觉就像一个世纪那么长。根据首字母提示及“I have been back in the UK fr three days, but it feels like a...”可知，此处指的是时间很长，感觉像一个世纪，“世纪”century，可数名词，由空前a可知，此处应用其单数形式。故填century。
