【題目】Zulema Munoz collects seaweed in a small coastal town 100 miles south of Santiago, Chile. A good week may see her cut 1,100 pounds of seaweed from the rocks where it grows.

Muftoz is one of the 30, 000 people for whom Chilean seaweed industry provides a livelihood. Throughout Latin America, the cultivation (種植) and collection of seaweed are gaining a support both as a source of food and as a means of ensuring food security in a region where 34 million people are food insecure and poverty affects 47 percent of the rural population. Countries such as Argentina, Brazil, Colombia, Cuba, Ecuador, Mexico, Peru, and Venezuela have all explored seaweed production for food. Yet as demand outpaces production and wild stocks have declined, more attention is being paid to sustainable cultivation and harvesting methods that can keep the industry surviving.

Seaweed has a long history in South American style of cooking. The native cooking of Chile made frequent use of cochayuyo, the most abundant of the country 750 types of seaweed. Today, cochayuyo is commonly found in place of meat incharquican, a traditional dish cooked slowly in a closed pan.

Kelp, a type of large brown seaweed, as the new vegetable is a global trend too, and for good reason. Nutritionally, seaweed is packed with iodine and other nutrients, and appears on trend-making menus in Google's New York cafeteria, though it used to be thought difficult to get people to eat it.

While 83 percent of cultivated sea vegetables are produced for human consumption, we aren’t just eating it. Seaweed is used in fertilizers and animal feed, and seaweed-based food additives are likely in many products in your kitchen and bathroom right now. Carrageenan, made from red seaweed, is in everything from shampoo and toothpaste to ice cream and some hot dogs.

While seaweed grows readily—there are concerns that humans are taking too much of the wild stuff. It is possible that overexploitation of natural seaweed resources could lead to significant ecological, economic, and social consequences at local, regional, and even global scales. In Latin American countries like Brazil and Peru, where the seaweed industry is based on harvesting wild seaweed rather than cultivated, the need for environmentally friendly models is urgent.

1What do you know about seaweed?

A. It is hard to grow. B. It is good to health.

C. It tastes delicious. D. It costs a great deal.

2What can we learn from the passage?

A. How people collect weed. B. What people do with seaweed.

C. How people cook with seaweed. D. Where people trade seaweed.

3Why is seaweed cultivated according to the passage?

A. To make the best of the seas and to increase the export of seaweed.

B. To help more people out of poverty and to open up its new markets.

C. To meet the needs of the market and to preserve the wild resources.

D. To cut the costs of seaweed industry and to benefit rural population.

【答案】

1B

2B

3C

【解析】海藻因為可以食用并對身體有益所以在拉美國家海藻需求量大。但是過度開采天然海藻會破壞生態(tài)平衡,因此拉美國家的人們開始種植海藻。

1細節(jié)理解題。根據(jù)第二段Throughout Latin America, the cultivation (種植) and collection of seaweed are gaining a support both as a source of food and as a means of ensuring food security in a region可以得知,海藻是一種食物來源對人類身體有益。故選B。

2推理判斷題。根據(jù)第二段Countries such as Argentina, Brazil, Colombia, Cuba, Ecuador, Mexico, Peru, and Venezuela have all explored seaweed production for food.得知,人們知道如何利用海藻。故選B。

3推理判斷題。根據(jù)第二段Yet as demand outpaces production and wild stocks have declined, more attention is being paid to sustainable cultivation and harvesting methods that can keep the industry surviving.可知,海藻市場需求大,以及最后一段It is possible that overexploitation of natural seaweed resources could lead to significant ecological(過度開采天然海藻會破壞生態(tài)平衡。)判斷出,人們種植海藻為了滿足市場需求和保護野生資源。故選C。

【題目】The African elephant, the largest land animal remaining on earth , is of great importance to African ecosystem (生態(tài)系統(tǒng)).Unlike other animals, the African elephant is to a great extent the builder of its environment. As a big plant-eater, it largely shapes the forest-and- savanna(大草原) surroundings in which it lives, therefore setting the terms of existence for millions of other animals that live in its habitat(棲息地).

It is the elephant’s great desire for food that makes it a disturber of the environment and an important builder of its habitat. In its continuous search for the 300 pounds of plants it must have every day, it kills small trees and underbushes, and pulls branches off big trees. This results in numerous open spaces in both deep tropical forests and in the woodlands that cover part of the African savannas. In these open spaces are numerous plants in various stages of growth that attract a variety of other plant-eaters.

Take the rain forests for example. In their natural state, the spreading branches overhead shut out sunlight and prevent the growth of plants on the forest floor. By pulling down trees and eating plants, elephants make open spaces, allowing new plants to grow on the forest floor. In such situations, the forests become suitable for large hoofed plant-eaters to move around and for small plant-eaters to get their food as well.

What worries scientists now is that the African elephant has become an endangered species. If the elephant disappears, scientists say, many other animals will also disappear from vast areas of forest and savanna, greatly changing and worsening the whole ecosystem.

1What is the passage mainly about?

A. Disappearance of African elephants.

B. Forests and savannas as habitats for African elephants.

C. The effect of African elephants’ search for food.

D. The eating habit of African elephants.

2What does the underlined phrase “setting the terms” most probably mean?

A. Fixing the time. B. Worsening the state.

C. Improving the quality. D. Deciding the conditions.

3What do we know about the open spaces in the passage?

A. They result from the destruction of rain forests.

B. They provide food mainly for African elephants.

C. They are home to many endangered animals.

D. They are attractive to plant-eating animals of different kinds.

4The passage is developed mainly by .

A. showing the effect and then explaining the causes

B. pointing out similarities and differences

C. describing the changes in space order

D. giving examples

【題目】Homestay provides English language students with the opportunity to speak English outside the classroom and the experience of being part of a British home.

What to Expect

The host will provide accommodation(住宿) and meals. Rooms will be cleaned and bedcovers changed at least once a week. You will be given the house key and the host is there to offer help and advice as well as to take an interest in your physical and mental health.

Meal Plans Available

Continental Breakfast

Breakfast and Dinner

Breakfast, Packed Lunch and Dinner

It’s important to note that few English families still provide a traditional cooked breakfast. Your accommodation includes Continental Breakfast which normally consists of fruit juice, cereal(谷物類食品),bread and tea or coffee. Cheese, fruit and cold meat are not normally part of a Continental Breakfast in England. Dinners usually consist of meat or fish with vegetables followed by desert, fruit and coffee.

Friends

If you wish to invite a friend over to visit, you must first ask your host’s permission. You have no right to entertain friends in a family home as some families feel it is an invasion of their privacy(隱私).

Self-Catering Accommodation in Private Homes

Accommodation on a room-only basis includes shared kitchen and bathroom facilities(設(shè)施) and often a main living room. This kind of accommodation offers an independent lifestyle and is more suitable for the long-stay student. However, it does not provide the same family atmosphere as an ordinary homestay and may not benefit those who need to practise English at home quite as much.

1The passage is probably written for ________.

A. host willing to receive foreign students

B. foreigners hoping to build British culture

C. travellers planning to visit families in London

D. English learners applying(申請)to live in English homes

A. Room cleaning. B. Medical care.

C. Free transport. D. Physical training.

A. To experience a warmer family atmosphere.

B. To enrich their knowledge of English

C. To entertain friends as they like.

D. To enjoy much more freedom.
