Lego is considering a brick (积木) rental plan in an attempt to cut down on plastic waste. The Danish toymaker has promised to make all its bricks from sustainable (可持续的) sources by 2030 and is investing significant resources into finding alternatives.

Tim Brooks, vice-president responsible for sustainability, said the company was “totally open” to the idea of a product rental plan but admitted that lost pieces could produce a significant problem. “What are the chances of giving them to an eight-year-old child and getting them all back again?” Mr. Brooks added.

“There is a lot of technical thinking that needs to be done. We are right at beginning of that.” Mr. Brooks said Lego was exploring several ideas with a view to producing the highest value from products while consuming the least amount of resources. He said many would “probably never see the light of day” and there was no current plan to try out a rental plan.

Lego has come under increasing pressure to reduce its carbon footprint among growing international alarm about the impact of plastic waste on the environment. It produces 19 billion pieces per year—36, 000 a minute—that are made entirely of plastic while much of the inside packaging is also plastic.

So far, the only breakthrough has been the development of a line of bricks made from plant-based plastic sourced from sugarcane. The green trees, plants and flowers were first included in Lego sets late last year but make up only 1%-2% of the total amount of plastic elements produced. Henrik Nielson, a production supervisor (主管) in Lego’s factory, said last year: “We need to learn again how to do this.”

Lego reportedly releases around a million tons of carbon dioxide each year, with about 75% coming from raw materials that go into factories. The company has invested more than 100, 000,000 euros and hired 100 people to research non-plastic alternatives. It is aiming to keep all of its packaging out of landfill by 2025.

1.Lego is making great efforts to ________.

A.promote its brick rental plan B.raise its production efficiency

C.explore ways to reduce plastic waste D.develop new products

2.According to Mr. Brooks, Lego’s brick rental plan ________.

A.is well under way B.has a long way to go

C.is totally useless D.goes against Lego’s interest

3.The writer tells of Lego’s stress of reducing plastic waste by means of ________.

A.figures B.examples

C.comparison D.classification

4.What is Lego’s attitude towards developing non-plastic alternatives?

A.Defensive. B.Determined.

C.Disapproving. D.Doubtful.

Gardeners may be able to cut down on the amount of weeds(杂草）killer they use by dealing with invaders at specific times of the day, such as dawn, a new study suggests.

Researchers at the University of Bristol have discovered that the 24-hour rhythms of plants leave them more defenseless to herbicides(除草剂) at different points in their daily 24 hour cycle.

They believe the findings could help farmers by reducing crop loss and improving harvests. And gardeners could benefit from knowing which weeds respond better at certain times of the day. In recent years, pesticides and herbicides have been implicated in the decline of important pollinating insects, such as bees.

Dr Antony Dodd，senior author of the new study，said: “The research suggests that, in future, we might be able to improve the use of some chemicals that are used in agriculture by taking advantage of the biological clock in plants.

Just like humans, plants have evolved to take advantage of cycles of night and day, with certain biological processes turning on at different times of the day.

Scientists have discovered that many drugs work much better in humans if they are given at specific hours. Aspirin, for example, has doubled the impact on thinning the blood if taken at night as opposed to in the morning. The process is known as ‘chronotherapy’ and researchers wanted to find out if the same concept could be applied to plants.

Many gardeners already know that plants drink in more water in the morning because their pores(气孔) are open to take advantage of early morning dew and water vapour. At the break of the day, plants are also not busy producing food throughphotosynthesis(光和作用）.The open pores could also be the reasons that chemicals are more effective at dawn and also at dusk.

The air is also likely to be stiller at dawn and dusk, meaning that pesticides or herbicides are less likely to be blown away to places where they are not wanted. Pesticide labels often warn against spraying on windy days in case they endanger people or animals. Many insects are active early in the morning and around dusk, also making very early morning and early evening effective times for insecticide.

Commenting on the study, Dr. Trevor Dines, Botanical Specialist at the conservation charity Plantlife, said: “This is fascinating research which will be of great interest to many gardeners like me. If anything used to think the opposite was true - that applying herbicides and pesticides late in the day would be better as they’d remain in Vet contact' with the plant for longer in the cool of the night and therefore be taken up or absorbed more effectively. This research knocks that assumption on its head”

1.Which of the following can replace the underlined phrase “implicated in” in the third paragraph?

A.restored to B.blamed for

C.limited to D.composed of

2.According to the research, what are the reasons for using herbicides in the morning?

A.The process of photosynthesis is most active in the morning.

B.Insects are more defenseless in the morning than any other time of the day.

C.Bigger pores on the plants make herbicides work more effectively.

D.The stronger morning wind blows pesticides away to more places.

3.What can be inferred from the last paragraph?

A.Gardeners were interested in combining science with gardening.

B.A long time had passed before herbicide was applied in farming.

C.The old assumption about the use of chemicals proved right.

D.Many gardeners used to spray herbicides at the wrong time.

4.What is the main idea of this article?

A.New chemicals have been found to help kill harmful insects.

B.Biological clock of plants could help gardeners use less weed killer.

C.Plants’ cycles can be taken advantage of to improve the environment.

D.The research on the effects of pesticides has enabled good harvests.

One of the hardest parts of planning a trip to Hawaii is deciding which of the major Hawaiian Islands you should visit. Each has its own personality and offers unique adventures and activities.

Oahu

Oahu has a bit of everything, packed in 597 square miles. You can hike into thick rainforests, and when you need a break, relax on powdery white sand beaches and stay at luxury resorts.

Oahu has become a great destination for families. The urban core （核 心）of Honolulu and Waikiki has historic sites, museums and bustling （熙熙攘攘的）and nightlife scenes. The island lives up to its nickname of the Gathering Place.

Maui

Maui is a great island for honeymooners. The Valley Isle has top-class resorts and golf courses, adjacent （毗邻）to some of the state's best beaches. A large dormant （休眠）volcano in east Maui at sunrise or sunset is a serene experience, as well as driving the Road to Hana, famed for its thundering waterfalls.

Kauai

Kauai is the oldest of the main Hawaiian Islands. The island gets a lot of rain, but that's what makes it so lively, you'll come across flowers and plants you've never seen before. For some of the best views on the island, visit Waimea Canyon, known as the Grand Canyon of the Pacific, and the Na Pali coast, boasting some of the world's highest sea cliffs.

Big Island

The Big Island is the only Hawaiian island still growing. Witness the power of Pele, the Hawaiian goddess of fire, wind, lightning and volcanoes with a visit to the Hawaii Volcanoes National Park. It's one of the few spots in the world where you can see lava flow. In fact, the Big Island has 10 of the world's sub-climate zones, from the snow-covered mountain of Mauna Kea, green forests of Waipio Valley to stretches of barren desert.

1.Which is young couples' favorite?

2.How is Oahu different from the other places?

A. It belongs to Hawaii. B. It offers the best beaches.
