托福閱讀：American food crops

今天我們給大家?guī)�來的是American food crops這篇文章的解題思路及題目分析，希望大家能應(yīng)用老師的思路，在自己的過程中多云用這些思路，相信大家的做題技巧會有提升。

What is the main purpose of the lecture ?

• A. To describe the trade in food crops between Europe and Americas

• B. To describe the introduction of American food crops to Europeans

• C. To describe the influence of American food crops on traditional Europeans

• D. To describe the difficulties of growing American food crops in European climates

引為主題的方式有三種

• 直奔主題式

• 背景引入式

• 離題式 TPO18，Conversation 2第1題

• So would it surprise you to learn that many of the foods that we today consider traditional European dishes that their key ingredients were not even known in Europe until quite recently, until the Europeans started trading with the native peoples in North and South America? I mean, you're probably aware that the Americas provided Europe and Asia with foods like squash, beans, turkey, peanuts. But what about all those Italian tomato sauces, Hungarian goulash, or my favorite, French fries, those yummy fried potatoes.

• 先介紹背景，然后用I mean來總結(jié)出自己的主旨，我們需要聽I mean之后的三句話，得出應(yīng)該是B

What does the professor imply about certain plants in the nightshade family?

• A. They grow best in Mediterranean climates

• B. Their leaves are high in nutritional value

• C. They were mistakenly believed to be related to potatoes

• D. They are dangerous when eaten by human beings

這道題是一道專業(yè)名詞解釋類的細節(jié)題，通常我們對于這個名詞都是比較陌生的，但是我們需要注意當(dāng)出現(xiàn)新名詞的之后的解釋。名詞不知道可以，但是解釋一定需要聽的懂

• The Nightshade family is a category of plants which also includes many that you wouldn't want to eat, like mandrake, belladonna, and even tobacco. So it's no wonder that people once considered tomatoes and potatoes to be inedible too, even poisonous. And in fact,the leaves of the potato plant are quite toxic.

教授提到Nightshade的植物，都是有毒的，經(jīng)過同意替換得出答案為D

What does the professor imply about Thomas Jefferson‘s attitude toward tomatoes?

• A It was typical of his unconventional way of thinking

• B It helped to advance his political career

• C It changed the eating habits of North Americans

• D It helped to make tomatoes popular in Europe

當(dāng)提及新人物時要注意該人物對應(yīng)的事件成就，或者態(tài)度等情況

• Student: But it seems like I heard didn't Thomas Jefferson grow them or something?

• Professor: Well, that's true. But then Jefferson is known not only as the third president of the United States but also as a scholar who was way ahead of his time in many ways. He didn't let the conventional thinking of his day restrain his ideas.

Not only，but also句型中but also之后的內(nèi)容還是比較重要，確定答案為A

原文

According to the professor, what was the long-effect of the introduction of American corn and potatoes to Europe?

• A It had a negative effect on the nutritional intake of people living near the Mediterranean Sea

• B It contributed to a shift in the balance of power from southern Europe to northern Europe

• C It encouraged the development of new types of cuisine in southern Europe

• D It led to the failure of many native European grain crops

原文

• Potatoes soon spread to France and other Northern European countries. And as a result, the nutrition of the general population improved tremendously and population soared in the early 1800s and so the shift of power from southern to northern Europe continued.

信號詞as a result以后跟出了答案，人口的增加最后導(dǎo)致了政權(quán)的遷移，最后我們確定答案為B

According to the professor ,what is one of the reasons why potatoes became popular in Ireland?

• A Potatoes were more nourishing than native Irish food crops

• B Potatoes grew better at higher altitudes than native Irish crops

• C Political leaders in Ireland encouraged the cultivation of potatoes

• D People in Ireland were not aware that potatoes are members of the nightshade family

原文

• And then, well as I said potatoes weren't really popular at first. But when they finally did catch on which they did first in Ireland around 1780.Well,why do you suppose it happened? Because potatoes have

the ability to provide abundant and extremely nutritious food crop, no

other crop grew in North Europe at the time had anything like the

number of vitamins contained in potatoes.

在對話中的設(shè)問句一般功能均為強調(diào)，之后為重點，我們能夠得出答案應(yīng)該為A

Listen again to part of the lecture Then answer the question

What can be inferred about the professor when she says this

• A She expects the student to provide an answer to her question

• B She is surprised by the student‘s question

• C She thinks that she knows what the student was going to ask

• D She expects other students in the class to express their opinions

在句中老師打斷了學(xué)生的回答，一般有兩種情況1老師已經(jīng)知道了學(xué)生要說什么2學(xué)生答案是錯的。這里答案是C她已經(jīng)知道了學(xué)生的答案。

關(guān)于American food crops這篇的習(xí)題就先跟大家分析到這里，如果同學(xué)們的處于瓶頸期或者英語基礎(chǔ)比較薄弱，
