【題目】---Peter is still in hospital now and he regrets drinking and eating junk food.

---No one knows the value of health he has lost it.

A.whenB.sinceC.afterD.until

【答案】D

【解析】

句意：——彼得現(xiàn)在還在醫(yī)院，他后悔喝酒吃垃圾食品了。——直到失去健康，人們才知道它的重要性 。

考查連詞辨析。when當(dāng)…時(shí)候；since自從；after在…之后； until直到…才，分析句意可知，此處表示“人直到失去健康，才知道它的重要性”。no one否定詞，跟until連用表示“直到....才”故選D。

【題目】閱讀下面短文，并用英語回答問題（請注意每小題后面的詞數(shù)要求）

Do you know about Artificial intelligence (AI) (人工智能） ?

AI is growing very fast now. AI is a group of technologies that help machines get, understand and use information to do tasks. AI’s recent developments have got a lot of social attention. Some people have welcomed AI because it makes things possible. For example, AI will have a big influence on areas like medicine and engineering. But this attention has also produced a lot of fear. Especially, many workers are worrying that AI could make them lose their jobs.

According to a recent study, nearly five percent of jobs will disappear because of AI. In some industries, AI is already doing the work that people used to do. Self-driving cars and trucks controlled by AI will also take away the drivers' jobs in the future.

On the other hand, AI will also create many new jobs for people. More people will be needed to write programs for AI systems (系統(tǒng)）and they will set up and work on them, too.

Meanwhile, jobs that require feeling, excellent communication skills with people will not be replaced (取 代) by AI. These include jobs in fields like teaching, nursing and personal training.

AI is here. It is changing how people live and work in many ways. That makes AI important to watch, not to fear.
