These days, most people in the UK and the US wear informal(非正式的)clothes. But sometimes it is important to wear the right thing.

Many British people don’t think about clothes very much. When they go out to enjoy themselves, they can wear almost anything. At theatres, cinemas and concerts you can put on anything you like:from beautiful suits and dresses to jeans and sweaters. Anything goes, but you should look clean and tidy. But in the UK, as well as in the US, men in offices usual]y wear suits and ties and women wear dresses or skirts (not trousers).

Doctors and business people always wear quite formal clothes. And in some hotels and restaurants, men have to wear ties and women have to wear tidy dresses.

In many ways, Americans are less formal than British people, but they are more careful with their clothes. At home, or on holiday, most Americans wear informal or sports clothes. But when they go out in the evening, they like to look nice. In good hotels and restaurants, men have to wear jackets and ties, and women have to wear pretty clothes.

It is difficult to say exactly(確切地)what people wear in the UK and the US, because everyone is different. If you are not sure what to wear, watch what other people do and then do the same. You'll feel good if you don't look too different from everyone else.

1.At concerts British people .

A.should wear sweaters B.can wear anything they like

C.should wear suits and ties D.have to wear sports clothes

2.Women in the UK and the US have to wear tidy dresses when they are .

A.at a cinema B.meeting friends at home

C.at a party D.having dinner in some top restaurants

3.What does the passage mainly tell us?

A.Women can’t wear trousers in offices.

B.We should wear differently because everyone is different

C.What British and American people wear now.

D.British people are more careful with their clothes than American people.

A team of engineers at Harvard University has been inspired by Nature to create the first robotic fly. The mechanical fly has become a platform for a series of new high-tech systems. Designed to do what a fly does naturally, the tiny machine is the size of a fat housefly. Its mini wings allow it to stay in the air and perform controlled flight tasks.

“It’s extremely important for us to think about this as a whole system and not just the sum of a bunch of individual components (元件),” said Robert Wood, the Harvard engineering professor who has been working on the robotic fly project for over a decade. A few years ago, his team got the go-ahead to start piecing together the components. “The added difficulty with a project like this is that actually none of those components are off the shelf (現(xiàn)貨供應(yīng)) and so we have to develop them all on our own,” he said.

They engineered a series of systems to start and drive the robotic fly. “The seemingly simple system which just moves the wings has a number of interdependencie(相互依賴) on the individual components, each of which individually has to perform well, but then has to be matched well to everything it’s connected to,” said Wood. The flight device was built into a set of power, computation (計(jì)算), sensing and control systems. Wood says the success of the project proves that the flying robot with these tiny components can be built and manufactured.

While this first robotic flyer is linked to a small, off-board (外置的) power source, the goal is eventually to equip it with a built-in power source, so that it might someday perform data-gathering work at rescue sites, in farmers’ fields or on the battlefield. “Basically it should be able to take off, land and fly around,” he said.

Wood says the design offers a new way to study flight mechanics and control at insect-scale. Yet, the power, sensing and computation technologies on board could have much broader applications. “You can start thinking about using them to answer open scientific questions, you know, to study biology in ways that would be difficult with the animals, but using these robots instead,” he said. “So there are a lot of technologies and open interesting scientific questions that are really what drives us on a day-to-day basis.”

1.The difficulty the team of engineers met with while making the robotic fly was that ______.

A.they had no model in their mind B.they did not have enough time

C.they had no ready-made components D.they could not control flight tasks

2.It can be inferred from paragraphs 3 and 4 that the robotic fly ______.

A.consists of a flight device and a control system

B.can just fly in limited areas at the present time

C.can collect information from many sources now

D.has been put into wide application

3.Which of the following can be learned from the passage?

A.The robotic flyer is designed to learn about insects.

B.Animals are not allowed in biological experiments.

C.There used to be few ways to study how insects fly.

D.Wood’s design can replace animals in some experiments.

4.Which of the following might be the best title of the passage?

A.Father of Robotic Fly B.Inspiration from Engineering Science

C.Robotic Fly Imitates Real Life Insect D.Harvard Breaks Through in Insect Study
