9.In an effort to discourage people from using plastics,scientists have been hard at work inventing alternative packaging products.From water bottles made from seaweed to cutlery(餐具)made from rice and wheat,a number of inventions are set to change the way we eat while we are on the go,or having a relaxing picnic in the park.
The idea of using seaweed to make eco-friendly(環(huán)保的)water bottles has been around for a few years.Recently,Ari Jonsson took his invention-a water bottle made from red seaweed-to show off at a festival.The bottles will only hold their shape as long as they are filled.As soon as these bottles are empty they will begin to break down,though they would be perfectly safe to eat.Ari Jonsson's bottles are a step closer to a widely used alternative to the current plastic ones.
The eatable water container is not the only product to add to our image of the future.Narayana Pessapaty has also created eatable spoons.After the success of his spoons.Mr Pessapaty is ready to expand and introduce forks and chopsticks to his menu.His aim is to largely reduce the amount of plastic waste,which is a huge problem for waste sites all over the world.It is a product that may take up to 500years to break down,and recycling companies worldwide are struggling to deal with it.
Aside from the obvious benefits to the environment,this new packaging is also cheap to produce and therefore cheap to buy.Even better is the fact that similar eatable cutlery can be made at home,possibly a science project for children or just fun with friends.Why not get experimenting and create your own recipes?

12.Why do scientists invent alternative packaging products?B
A.To make people's life more convenient.
B.To reduce the amount of plastic waste.
C.To charge the way we picnic outside.
D.To show off their inventive talents.
13.What makes Ari Jonsson's water bottles eco-friendly?D
A.They can be made at home.
B.They are cheap to produce and buy.
C.They will hold their shape when they are filled.
D.They will break down themselves when empty.
14.What do Ari and Narayana's inventions have in common?B
A.They are convenient to carry.
B.They are safe to eat.
C.They can be used for a short time.
D.They are heavier than plastics.
15.What can be inferred from this passage?A
A.Home-made eatable cutlery is likely to be popular.
B.Eatable cutlery'will completely replace plastics in the near future.
C.No recycling companies can breakdown plastic waste.
D.It's unsafe for individuals to invent eatable cutlery at home.

分析 文章主要講述了科學(xué)家發(fā)明可替代的包裝產(chǎn)品是為了減少塑料廢品,他們是環(huán)保的,用起來也安全.同時國產(chǎn)食用餐具很可能是受歡迎的.

解答 12.B細(xì)節(jié)理解題.根據(jù)第一段第一句"In an effort to discourage people from using plastics,scientists have been hard at work inventing alternative packaging products."可知科學(xué)家發(fā)明可替代的包裝產(chǎn)品是為了減少塑料廢品.故選B.
13.D細(xì)節(jié)理解題.根據(jù)第三段第三句"As soon as these bottles are empty they will begin to break down,though they would be perfectly safe to eat."可知Ari Jonsson的水瓶空的時候自動毀掉,所以他的水瓶是環(huán)保的.故選D.
14.B細(xì)節(jié)理解題.根據(jù)第三段第三句后半句"As soon as these bottles are empty they will begin to break down,though they would be perfectly safe to eat."再根據(jù)第三段中"After the success of his spoons.Mr Pessapaty is ready to expand and introduce forks and chopsticks to his menu."可知他們發(fā)明的共同點就是安全地吃.故選B.
15.A推理判斷題.根據(jù)最后一段第二句"Even better is the fact that similar eatable cutlery can be made at home,possibly a science project for children or just fun with friends."可知國產(chǎn)食用餐具很可能是受歡迎的.故選A.

4.A recent survey in the United States showed that the average family spent more money on its
pets than on its children.Although rather shocking,it should not surprise anyone who has seen the
 doggy parlors(客廳)where loved pets rest.Are Americans unique m treating their little friends in this
way?(36)G
(37)F They certainly cost much.Last year the British public spent two hundred million
pounds on pet food alone,to say nothing of veterinary(獸醫(yī)的)  bills or animal furniture.It is
 difficult not to feel angry about this when considering what the same amount could do for victims of
 starvation and poverty.
There are a variety of reasons why I find pets-raising alarming.They cause physical problems.
An example of this is New York where they have great difficulty getting rid of the mess that dogs
leave on the streets.(38)A  But in a number of large cities It is a major problem.
Another problem is the carelessness of pet owners.Most little children want a dog or a cat and
they continually push their parents until they get one.But the parents don't realize how much time and
money must be spent on the little friend after it's brought home.Then they abandon it.(39)EYou must have read of children being hurt by pets on the street.
Lastly,1 would suggest something should be done about it.In my view,it's time we stopped being sentimental(傷感的)about pets.(40)C  This will lead us to discovering cures for serious human diseases.

A.Many people find this funny.
B.There's no definite answer to that question.
C.I can see no reason why we should get upset when animals are cut up for medical experiments.
D.Pet foods often contain more vitamins than human food.
E.As a result.they are allowed to run free.
F.This can be seen when we look at pet foods.
G.No.the English too,pay more attention to their pets.
