阅读下面四篇材料,然后从A、B、C、D四个选项中选出最佳选项。

With rising food prices, growing population and environmental problems, many people are worrying about how we will feed ourselves in the future. Don’t worry. Scientists are trying to find some answers.

Some scientists believe insects will become a staple of our diet. Insects provide as many nutrients as ordinary meat and a great source of protein(蛋白质) , they also cost less to raise than cows and use less water. About 1,400 species are suitable as food for humans. Many people have already eaten insects as a part of their diet. Locusts are popular in Africa, wasps are a dish in Japan, and crickets are eaten in Thailand. The Dutch government is preparing for insect farms and has invested one million euros into research.

In the future, land and fresh water will be in short supply. It is possible that people need to find a reliable food source in the ocean. Scientists have already found one at the bottom of the food chain---seaweed. It has long been a staple in Asia, and countries including Japan have huge seaweed farms. Such farms can easily work in other countries and be very successful. The great thing about seaweed is that it grows at an amazing rate. It’s the fastest growing plant on earth.

Scientists are also working in the lab to solve the problem of food shortage. A few years ago, European scientists successfully produced lab meat, also known as cultured meat. They grew muscle tissue using stem cells(干细胞)taken from cows. The experiment was funded by NASA to see if lab meat was a food astronauts could eat in space.

In 20 years’ time , lab meat is likely to become a popular dish of our diet. According to research, growing meat in a lab rather than slaughtering(屠宰) animals can greatly reduce greenhouse gases, along with energy and water use. People can also reduce fat from the meat and add nutrients.

阅读材料,将A、B、C、D四个标题与标题后的四段文字配对,然后完成50题。

A. Remembering the reader B. Writing the first sentence

C Reading and rewriting D. Thinking on paper

Sooner or later everyone has to write something like a thank-you note, a report at a meeting , a complaint or an apology.If you hate writing assignments in school, or if you still fear to put pen to paper, facing that empty page is almost as frightening as you’re facing a tiger.How to write it? There’s no mystery.Clear writing is just clear thinking.Here are some techniques for you.

1.

Sit down with a pencil and paper or at the computer screen and start thinking about what you want to say, why it’s important, why it matters, and what its impact is on the reader.Just get the ideas down.The next step is to go back and put them in order.

2.

Try to make your first sentence catch the reader’s eyes, because if it can’t, the reader isn’t going to read on.Get a good, clear lead sentence that summarizes your points and that answers the reader’s question “What’s in it for me?” If you can’t do it in one sentence, then do it in two or three but keep them short.

3.

Short, simple words are better than long words.Short sentences are better than long sentences.Remember that the goal is to communicate, not to express yourselves.Most people are so devoted to what they want to say that they forget somebody else has to be able to read it.Too much information makes you lose readers before they understand what you want to say.

4.

Read what you have written out aloud, and listen for any awkward sentences.All good writers read, then rewrite.Back off a little bit from what you’re writing.It’s an old standard, but if you can, write something and come back a day later.

5.How do you write a good article? Please write down one of your suggestions.(不少于5个单词)
