Growers around the world are using new methods to grow grapes to make wine. They use natural and organic methods to control harmful insects and weeds instead of using chemicals. Now, a winery in Canada has adopted a natural way to control its grapevines (葡萄藤).The Featherstone Winery is in southern Ontario. The grapevines, like other plants, need to be cut every year.

Cutting grapevines must be done very carefully. Only a targeted area of leaves is removed from the lower part of the vines to help the grapes grow better. But at the Featherstone Winery, no man or machine does the cutting. Instead, the job is done by 40 little wooly lambs.

David Johnson owns the vineyard. He says he learned about using lambs while visiting wineries in New Zealand. The young lambs are perfectly designed to do the job. They eat the grape leaves on the lower parts of the vine. But they are not tall enough to reach the grapes. They only weigh about 22 kilograms, so they do not beat down the soil. And their waste makes good organic fertilizer. In addition, using the lambs costs much less than hiring workers to cut the vines for seven weeks in summer. And when the cutting is done in August, the lambs become tasty dishes.

Mr Johnson says he had a difficult time finding enough lambs to do the job. There are about 50 million lambs in New Zealand. But there are not nearly as many in Ontario. Also, some organic pesticides (杀虫剂) are harmful to lambs. And the lambs must be watched to make sure they do not eat too much of the grapevines.

David Johnson says the lambs help him carry out his environmental ideas about farming. They are lovely and peaceful and he likes having them in his vineyard. People visiting the vineyard also enjoy watching the lambs do their job.

A. don't cut grapevines every year

2.In order to help the grapes grow better, growers _____.

A. only have to remove the dead leaves

D. should let little lambs do the cutting

3.Paragraph 4 is mainly about _____.

A. the future of getting lambs to do the cutting

B. the worries about using organic pesticides

C. the ways to get lambs to do the cutting

D. the problems related to lambs doing the cutting

4.We can infer from the passage that David Johnson______.

“Data is the new oil.” Like the sticky black thing, all those Is and 0s are of little use until they are processed into something more valuable. That something is you.

Five of the world’s ten most valuable companies are built on a foundation of tying data to human beings. Google and Facebook want to find out as much as possible about their users’ interests, activities, friends and family. Amazon has a detailed history of consumer behavior. Tencent and Alibaba are the digital wallets for hundreds of millions of Chinese; both know enough about consumers to provide widely used credit scores. Those with a good Zhima credit score, provided by Alibaba, enjoy discounts. Those without receive few offers. In other words, data are used to decide what sort of access people have to services.

That data are valuable is increasingly well-understood by individuals, too, especially because personal information is so often leaked（泄露）or stolen. The list of companies that have suffered some sort of data leak in 2018 alone reads like a roll call of household names: Facebook, Google, British Airways and so on. Such events have caused a switch in the public understanding of data collection. People have started to take notice of all the data they are giving away.

Yet few people have changed their online behavior or exercised what few digital rights they possess. Partly this is because managing your own data is time-consuming and complex. But it is more because of a misunderstanding of what is at risk. “Data” is an abstract concept. Far more solid is the idea of identity. It is only when “data” is understood to mean “people” that individuals will demand responsibility from those who seek to know them.

The fossils of past actions fuel future economic and social outcomes. Privacy rules and data-protection regulations are extremely important in protecting the rights of individuals. But the first step towards ensuring the fairness of the new information age is to understand that it is not data that are valuable. It is you.

1.The example of Zhima credit scores is mentioned to show __________.

A.data help companies target their services

B.credit scores change people’s way of life

C.Alibaba gains popularity among customers

D.people prefer to be offered discounts

2.What has caused a change in the public understanding of data collection?

A.The development of companies. B.The history of consumption.

C.Cases of data leak and theft. D.Lists of household names.

3.People don’t protect their data well mainly because __________.

A.they find it time-consuming and complex

B.they are not fully aware of its importance

C.they have no access to their personal data

D.they are afraid of taking responsibility

4.What is the author’s purpose in writing the text?

A.To defend companies’ use of data.

B.To show the economic value of data.

C.To call for more regulations to protect data.

D.To advocate a new way of thinking about data.

Students who say they never or hardly ever used dictionaries may speak English well but usually write poorly, because they make many mistakes.

The students who use dictionaries most do not learn especially well either. The ones who look up every new word do not read fast. Therefore they do not have time to read much. Those who use small two-language dictionaries have the worst problems. Their dictionaries often give only one or two words as translations of English. But one English word often has many translations in a foreign language and one foreign word has many translations in English.

The most successful students are those who use large college edition dictionaries with about 100,000 words but do not use them too often. When they are reading, these students first try to get the general idea and understand new words from the context. Then they reread and use the dictionary to look up only key words that they still do not understand. They use dictionaries more for writing. If they are not sure how to spell a word, they always use a dictionary. Also, if they think a noun might have an unusual plural form, they check this in a dictionary.

1.The writer thinks that ___________.

A．choose a good dictionary, and you’ll be successful in learning English
