1 . When water is cold, people will find it uncomfortable to swim. Wetsuits(潜水服）can help keep people warm.    1    So wetsuits are important. In many water sports, you can find people wearing them.

The wetsuit doesn't have a long history. According to studies, the wetsuit only began during WWII when Italians started wearing wetsuits that were made of rubber. And it was widely believed in 1951, Hugh Bradner began working to improve the equipment.     2    

Now there are many kinds of wetsuits. Contrary to what some may think, wetsuits do not work by keeping the diver(潜水员）dry; they are designed to let water into the suit. This thin layer of water is trapped（保存）between the diver and the suit. And it's allowed to move between the skin of the diver and the inside layer.     3    And it can help keep the diver comfortable during the diving process. That's why it's important to have a nice, tight fit for a wetsuit.

    4    The shorter wetsuit often provides cover for the main part of people's bodies. This kind of wetsuit works well with boating, water skiing, swimming, etc. A longer wetsuit can completely cover the body, including long legs.With more protection for the body, it may be used in cool weather conditions.

Wetsuits can also differ in thickness. They range from about 0. 5mm to 8mm in thickness. It's true that thicker wetsuits are more likely to affect your movement.     5    Generally, the colder the water you plan to dive in, the thicker the wetsuit should be.

A．But they're much better at giving you warmth.

B．As for the difference, wetsuits can differ in size.

C．The history of the wetsuit is an interesting story.

D．This led to the development of a kind of new wetsuit.

E．Many wetsuits are very light and easy to wear and take off.

F．As a result, the water gradually warms up to body temperature.

G．And they can provide protection from the sun and cuts from rocks.

5 . Food waste is a growing problem both in America and across the globe. In North America alone about 30-40% of food ends up as rubbish each year. While much ends up as rubbish, over 48 million Americans live in households that do not have enough food! Now, concerned citizens are trying to raise awareness of the issue with some creative ideas.

In New York’s Westchester County, students at 18 schools join in a program called We Future Cycle. Started by Anna and Ashley in 2014, it teaches kids to recycle, compost (堆肥), and most importantly control food waste in an easy and efficient manner.

Lunch areas at those schools are equipped with three clearly marked bins— compost, recycle and share. While the first two are common in schools, the third is rare. This is the bin where kids can put their unwanted drinks, fruits, and even untouched sandwiches. Food there is available for any student that wants them. Whatever remains at the end of the day is given to the local soup kitchen or food bank. Anna says the three bins have helped reduce the number of trash bags produced at the mid-day meal from an average of 22 to just 2!

To ensure kids form similar habits at home, the non-profit has created plans to educate families about the importance of sorting waste into the proper streams of recycling, composting, and food to donate. They also urge parents to have open conversations with their kids about food choices.

Kids are not the only ones that waste food. Adults are equally bad, if not worse! To fight that, Brooklyn-based Josh founded Salvage Super Club in 2014. The randomly organized dinners promise customers a multi-course meal for merely 50 dollars per person. The delicious food is made from perfectly safe ingredients (成分)   that are past their prime and, therefore, headed for the compost or trash bin.

1. The underlined word “awareness” in Paragraph 1 probably means__________?

A．understanding	B．hope
C．doubt	D．value

2. What do students at Westchester County do to save food?

A．Use dustbins instead of plastic bags for left-over food.

B．Put their unwanted food in the bins and learn to share.

C．Get the children to educate their parents at home.

D．Only get single-course food for 50 dollars when eating out.

3. What can we infer from Paragraph 5 ?

A．Parents are to blame for the children’s bad habits.

B．Parents do not encourage children to save food.

C．Parents are as wasteful as children about food.

D．Parents have set an example for the children.

4. Which of the following will the passage be likely to continue with?

A．More information about food bank.	B．How to improve food production.
C．The importance of saving food.	D．Other creative ways to save food.

6 . Fast walkers may live longer than dawdlers (缓慢的人)— regardless of their weight, a new study suggests.

Researchers at Leicester University analyzed data on 474, 919 people with an average age of 52 in the UK Biobank between 2006 and 2016. They found women who walked briskly had a life expectancy of 86.7 to 87.8 years old, and men who kept up the pace had a life expectancy of 85.2 to 86.8. Slow walkers hadn’t much encouraging prospects (前景): women had a life expectancy of 72.4, and men of 64.8 years old, if they were more leisurely in their movements. According to the paper, published last week, that ratio held true even if the fast walkers were severely overweight. It does not necessarily mean fast walkers will live longer. Experts say it suggests walking speed could be a simple way for doctors to judge their patients’ general health alongside other tests.

It is hardly the first study holding up walking speed as a powerful evidence that appears to improve and determine our health.

In 2011, the Journal of the American Medical Association (JAMA) published a study by Stephanie Studenski, who found the same: walking speed was a reliable predictor of life expectancy.

In 2013, US researchers found walking pace was linked to lower heart disease risk and longer life expectancy. In 2018, a study from the University of Sydney found picking up your walking pace to even an “average speed” could cut your risk of premature death by a fifth.

And Tom Yates, the physical activity professor at Leicester who's behind the latest study, has been publishing findings on this connection for years.

In 2017, he analyzed the same UK Biobank data and found walking speed appeared to affect the risk of dying from heart disease — concluding that the slowest walkers were twice as likely to suffer a heart-related death compared to quick walkers.

B．Fast walkers have a simple way of living.

C．Walking speed can help doctors know about their patients’ general health.

3. What did US researchers find?

A．Walking slowly is bad for people's health.

B．Walking speed can predict a person’s life expectancy.

C．People won't die early by increasing their walking pace.

D．Lower heart disease risk is determined partly by walking pace.
