Besides performing ancient Chinese music, the orchestra is also trying o 7 music styles.

Museum experts(专家)say that the older the objects are,the more the insects seem to like them.That's a problem because these things can't e 5 be repaired.As a result,museums will try almost anything to s 6 insects from harming their collections.For example,a new object will be kept separately at first.Then, when staff(工作人员)are sure there are no insects inside,it can be put on show.If insects are f 7 in a piece of clothing or art,placing it in a freezer(冷冻柜)is one way of getting rid of (除掉)them, But now one museum in the US has decided to try something new.They are t 8 a dog to find insects.Dogs have an e 9 sense of smell.Usually the dog sits down to show what it has found.Staff at the Museum of Fine Arts, Boston hope that their dog,Riley,will learn to do this when it finds insects.They say that at the moment it's just an experiment.However,if Riley can help find insects b 10 they do a lot of harm,other museums are sure to be interested. 1. 2. 3 4. 5. 6. 7. 8 9 10. 中考专项精品试题分类英语 (八)(2023·西青一模) A girl was working as a nurse in a private hospital.One day,a patient with serious disease was brought to the hospital,but had to be transferred()to another hospital at once for an o 1 H 2 the director of the hospital said the patient couldn't be transferred unless he paid his bill first.The patient's family was very poor.They have no c 3 but to ask if they could pay the bill after the operation because the patient was close to death.But t 4 request was refused.

Most drivers today use gestures to show their p 2.They wave a car into a lane 道)，or nod at passers-by and cyclists,to let them c 3 the street.But self-driving cars don't have this ability.What can they do?US maker Ford and its partner Virginia Tech(弗吉 尼亚理工学院)think they have the answer. The team is testing a method that use4 to show what self-driving cars are doing. For e 5 if a driverless car is yielding( 路)，it can flash two white lights side to side.A white light tells there are no humans in the car. A slow blinking light shows the car is coming to a stop.A rapidly flashing light tells passers-by that the car is about to speed up. To test the method on r 6 roads,the team designed a special suit that looks exactly like a car seat.When a driver wears it,it appears to people that the car is really driverless.
