1 . Animals grow up in different ways. Some newborn animals are helpless, but their mothers protect them. A newborn kangaroo is very small. It is only a few centimeters (cm) long. It closes its eyes and doesn’t have hair. It stays safe in its mother’s pouch (育儿袋) for a long time. A newborn monkey cannot walk. Its mother carries it everywhere.

2 . Do you know that every year volunteers collect millions of rubbish on beaches around the world? More and more people are searching for ways to reduce plastic use. A few small changes of your daily habits can quickly lead to less plastic waste.

    1    It only takes a few minutes to drink a bottle of water, but the plastic bottle has to take hundreds of years to break down. Make sure you have a reusable bottle to fill up instead of buying bottled water.

Choose reusable bags instead of plastic bags.     2     You can either keep your fruit and vegetables loose (零散的) or use reusable cloth bags. When you’re ready to check out, put your things into cotton shopping bags.

Take your dinner set with you. It’s helpful to carry a diner set and a cloth napkin in your bag.     3    Drink directly from the cup. Drinking straws (吸管) are one of the most common waste things that are collected during the beach cleanup. Instead of drinking your iced coffee tea through a straw, just drink it from the cup.     4    

Keep reusable bags or boxes nearby. Plastic-free living is easier if your reusable bags or boxes are easy to get, so make sure you keep them in your bag, car, or at your office.     5    Remember that our small efforts make a big difference in waste reduction.

6 . A new kind of hybrid wheat now available to American farmers may help reduce fears over genetically engineered crops. The new hybrid wheat is being introduced as seed companies worldwide seek to increase production because of reducing grain supplies. The hybrid wheat was developed by a Chinese-owned agriculture company. The product was created with-out genetic engineering. The first seeds to grow the wheat will be released on 2,000 to 2,800 hectares of American farmland next year, according to Reuters reports.

Developers or breeders create hybrid wheat by taking away the natural ability of plants to pollinate (授粉) themselves. Instead, female wheat plants in a field are pollinated by male plants of a different line. The goal of the process is to create seeds that can produce bigger crops and better resist harmful environments. The fertilized female plants produce a new kind of hybrid. Using this hybrid technology permits breeders to choose the best elements from two parent seeds to produce new seeds containing the best characteristics of both.

Producers say when seed companies produce hybrid wheat seeds, some female plants often fail to become fertilized because they depend on unpredictable winds to carry pollen (花粉).Pollen is a substance produced by plants when they reproduce. During some seasons,pollen is released into the air and carried to other plants to be fertilized. Producers say the fertilization of each plant is more certain during wheat’s natural process of self-pollination.

Researchers say the new hybrid wheat has to take long to come to market because the development process is more costly and complex. It could be important in increasing wheat yields and avoiding being linked to GMO development. GMO stands for genetically modified organism. Genetically modified wheat has never been grown for industry purposes because of fears that allergens or poisons might be created. Wheat is used to make numerous major foods worldwide.

Dave Hankey owns a seed company in Park River, North Dakota. He told Reuters, “Because of the resistance to genetically modified stuff, the hybrid wheat would be considered better and safer.”He added it would certainly be the public view.

1. Which of the following leads the new hybrid wheat to be developed?

A．The existing unsafe grain.

B．The decreasing output of food.

C．The application from American farmers.

D．The Chinese agriculture company’s proposal.

2. What is expected of the seeds of the new hybrid wheat?

A．Requiring less fertilizer.

B．Producing tinier crops.

C．Having better adaptability.

D．Improving their natural self-pollination ability.

3. What can we learn about the development of the new hybrid wheat?

A．It is complex but economical.

B．It is simple and fruitful.

C．It is temporary.

D．It is demanding.

4. What would be the public attitude to the hybrid wheat according to Dave Hankey?

A．Indifferent.

B．Resistant.

C．Appreciative.

D．Cautious.

THE BEST JOB IN THE WORLD

How would you like to spend six months living on an island and looking after the Great Barrier Reef? The working hours are flexible and accommodation is provided. Key duties include exploring the islands of the reef and finding out what the area has to offer. You’ll need to report back via weekly blogs, photo diaries and video updates. You’ll also be asked to promote the islands through newspapers, magazines and TV interviews.

It was actually a very clever means to highlight the importance of the Great Barrier Reef and the need to protect it.

About the size of Japan, it even can be seen from outer space. More than 25 million years old, the Great Barrier Reef is made up of living coral growing on dead coral. It is host to many species of birds and sea creatures. But this unique and delicate place is now under threat from pollution and climate change.

To get this job, the candidates had to make a short video showing how much they knew about the reef. They also needed to prove why they were the best person to do the job. Out of the thousands of applicants, eleven were selected, including a young woman from China. Eventually, the job was offered to Ben Southall from the UK.

In addition to blogging, taking photos and writing articles about the reef, he made a number of appearances on television to argue in favour of its defence. He also worked as a presenter for the National Geographic Channel, before going on to write a book about his experiences. Ben later joked that the job should have been advertised not as the “best”, but the “busiest job in the world”!

The most important thing was that people all over the world became aware of the beauty of the ocean in the area. What’s more, they came to understand the delicate balance that the environment exists in and what can, and must, be done to protect the reef. That way, it will remain a safe habitat for wildlife, as well as a dream destination for the millions of tourists who visit it each year.

1. What’s the purpose of the job advertisement?

A．To protect the Great Barrier Reef.	B．To build the Great Barrier Reef more beautifully.
C．To attract more candidates.	D．To attract more tourists to travel in Australia.

2. What problem was the Great Barrier Reef faced with?

A．Lack of tourists.	B．Natural disasters.
C．Pollution and climate change.	D．Disappearing of the islands.

3. Which of the following is NOT true about Ben?

A．He took photos and wrote articles about the reef.	B．He appeared on television many times.
C．He worked as a host for one channel.	D．He told jokes on TV.
