1.5 Quiz on the structure of IELTS writing
1、单选题：
Questions 1-5: The sentences in each question are listed randomly. Please choose the most logical arrangement from the four choices, A, B, C and D. Question 1: 1. It is hard to conceive of a world without banks, partly because they are so visible. Picture the horizon of any big city, and the skyscrapers in view are usually banks.2. Morgan Stanley looms over Times Square; Bank of America over Bryant Park. 3. Commuters emerge from Grand Central station in New York in the shadow of the Park Avenue base of JP Morgan Chase. 4. In Singapore the top floors of the offices of Standard Chartered and UOB house rooftop bars looking out over the entire city.5. Even in places like Auckland, Mexico City or Jakarta, the logos adorning the tallest buildings are those of ANZ, BBVA or HSBC.6. In London the skyline is dominated by oddshaped towers in the City and Canary Wharf.

Question 2: 1. Technological change means nearly all payments are settled digitally, rather than with notes or cheques. And banks are also bigger. 2. The total assets of the world’s biggest 1,000 banks were worth some $128trn in 2020, dwarfing annual global gross product of $84.5trn.3. Much has changed about banking since Bagehot’s day. 4. The biggest banks were in London; now they are in New York, Beijing and Tokyo.

Question 3: 1. They are shredded separately in special machines filled with liquids or gases that suppress combustion.2. But lithium-ion batteries, the type used in electric vehicles, are inflammable, so need careful handling.3. Generally speaking, electrical waste is shredded in bulk before it is sorted and reprocessed.The result, called “black mass”, is then processed to extract its valuable components.

Question 4：1. But there is still a long way to go. 2. That may be up from 17% in 2016, but still leaves a lot of mothers uncovered.3. Only 27% of American employers offered paid parental leave in 2019.4. A survey of female techindustry employees in 2018 found that 44% of women who had taken maternity leave had taken off less time than their entitlement because they thought a longer break would damage their careers.5. Even where leave is available, many women don’t take full advantage.

Question 5：1. They still struggle with guilt.2. Worse still, female employees routinely toiling more than 60 hours a week were more than three times as likely to develop heart disease, cancer or diabetes than those on a conventional 40hour schedule.3. Unsurprisingly, a study found that chronic stress levels are 40% higher in women who are employed and bringing up two children than in childless working women.4. One executive was on the phone with an important client in her locked office, only for an impatient toddler to bang on the door and repeatedly scream,“You don’t love me.”5. Working mothers are still overloaded.6. Mothers who are employed fulltime spend nearly twothirds more of their day feeding, bathing and caring for their children (under six) than their employed husbands do.

1、单选题：
Read the following passage and answer questions.Bird FlocksFlocks of birds can get only so big before falling apart. A new study shows that flocks of different sizes behave differently, and could help explain how animals like birds and fish coordinate their movements.Previous work has shown that in large flocks, changes in distance between members propagate rather like sound waves. Now a study by Andrea Cavagna of the Sapienza University in Rome and colleagues has found that changes in flying direction also spread like a wave, but dampen more quickly — as if moving through mud rather than air.They examined 3D datasets of flocks of starlings flying and turning and found that while sound-like waves spread best in bigger flocks, the waves transmitting information about direction spread best in smaller flocks.Their models showed that in a range of medium-sized flocks, neither strategy works effectively. Coordination between members is impossible and the collective flock structure breaks down.These limits could help explain flock behaviour, Cavagna says. For example, large flocks of around 10,000 birds tend to appear wobbly as one part changes direction before the rest. Flocks of 1,000 birds or less behave more rigidly as changes in direction can quickly spread across the entire flock.Question 1What is the main developing pattern of this passage?
选项：
A: conclusion and explanation
B: simple flow
C: problem and solution
D: comparison and contrast
答案: 【 conclusion and explanation】

Read the following passage and answer the questions.Birds Flying in a TruckIt's a question that had US TV show Mythbusters filling a truck with pigeons and weighing it while getting them to fly. Now it seems there's some truth to the idea that a truck driver carrying a cargo of birds can lighten the load by making the birds fly — but it also makes it heavier.So says David Lentink of Stanford University in California, whose team has designed a system for measuring the aerodynamic forces generated by an untethered bird in flight.Weighing a bird on the wing isn't easy, says Lentink. As it flaps its wings, it pushes on the air both above and below, meaning its effective weight changes. To make things harder, the way it moves the air changes several times a second. "Your bathroom scales take a few seconds to determine your weight," he says. "We needed a system that was super-fast in comparison."What they came up with is essentially a box with pressure pads on all of its interior walls that precisely measure fluctuations in air pressure 100 times each second.By filming Pacific parrotlets (Forpus coelestis) taking off and landing inside the box, and measuring the forces the birds created, Lentink's team found they generate almost no vertical force, on the wing's upstroke — making them effectively weightless. On the downstroke, though, they push on the air so forcefully that they generate a vertical force of up to twice their body weight."So if the birds in the cargo all flap at the same time, then the lorry would have to support twice the weight of the birds during the downstroke — and none of their weight during the upstroke," says Lentink. In reality, birds tend to flap at different times, meaning the cargo will, on average, maintain a stable weight.Their "scales" may also allow more precise measurement of aerodynamic performance of flying drones, says Lentink.

A: cause and effect
B: simple flow
