选项中有两项为多余选项。
Many students want to learn a foreign language well, but what must they do? In my opinion, in order to know a foreign language thoroughly, four things are necessary. 1Secondly, we must be able to speak it ourselves correctly with confidence and without hesitation. Thirdly, we must be able to read the language, and fourthly, we must be able to write it. 2There is no easy way to succeed in language learning. A good memory is a great help. 3It is not much use learning by heart long lists of words and their meanings, studying the dictionary and so on.4If we are satisfied with only a few rules we have memorized, we are not really learning the language. “Learn through use” is a good piece of advice for those who are studying a new language. Practice is important. 5A.We must learn by using the language.B.To master a foreign language is very important.C.Firstly, we must understand the language when we hear it spoken.D.We must be able to make sentences that are grammatically correct.E.We must study how we have to do to learn a foreign language.F.But it is not enough only to memorize rules from a grammar book.G.We must practice speaking and writing the language whenever we can.1. 2. 3. 4. 5.答案[语篇解读]文章就如何学好一门外语给出了几点建议。
北邮-大学英语2-第一阶段作业 答案

B. onesC. theseD. those学生答案: D; 标准答案: D;2.3. 试题分值:50.04. 得分:[5, 5, 5, 5, 5, 5, 5, 5, 5, 5]5. 提示:[1]C.考查主谓一致。
首先我们根据文章可以看出时态应该是一般现在时,所以B和D全部排除。
解决此题还要用到一个知识点:当主语是分数或百分数时,谓语动词的单复数由of 后面的名词决定。
再看这句话的主语是“75% of the earth’s surface”(地球表面的75%),这个主语中的“surface”是不可数名词,所以后面的谓语用单数形式“is”。
[2]A.考查名词辨析。
本句大意是“这么多水量中有97%都是海水,或称作咸水”。
解题关键是“水量”用哪个词来表达。
因为“水的数量”是不可数的,所以选择一个不可数名词才可以,即amount。
number意思是“数目”,但是它表示的“数目”是可数的。
volume的意思是“体积,容量”,意思不适合这里。
size的意思是“尺寸”,意思也不适合。
[3]A.考查连词辨析。
根据本句的意思(上题已经提到),我们选择or,其意思是“或者说”,用来引导同义词作补充说明。
[4]C.考查名词辨析。
source的意思是“来源”,resource的意思是“资源”,origin的意思是“起源”。
original一般作形容词用,意思是“起初的,原始的”,作名词用时意思是“原件,原稿”。
本句表示“别的水源”,当然应选择source来表达。
[5]D.考查定语从句。
“fresh water”后面的那个句子是一个定语从句。
又因为这个定语从句是非限定性的(判断的标志是fresh water后面的那个逗号),所以只能选择which来做定语从句的引导词。
[6]C.考查固定搭配。
“need for”的意思是“对……的需求”。
本句大意是“我们对水的需求在不断增加――几乎与日俱增”。
[7]A.考查形容词辨析。

B Many of us love July because it’s the month when nature’s berries and stone fruits are in abundance. These colourful and sweet jewels from British Columbia’s fields are little powerhouses of nutritional protection. Of the common berries, strawberries are highest in vitamin C, although, because of their seeds, raspberries contain a little more protein(蛋白质), iron and zinc (not that fruits have much protein). Blueberries are particularly high in antioxidants(抗氧化物 质). The yellow and orange stone fruits such as peaches are high in the carotenoids we turn into vitamin A

The idea is that the rich don't accumulate wealth simply in order to (1) it. Rather they accumulate wealth in order to display it, and their happiness is (2) by their neighbors' envy. As a result, the country finds itself in the grips of a "luxury fever" —families with (3) incomes of $50,000 try to emulate ( 仿效) the consumption of those with $70,000, who in turn try to emulate those with $140,000, and so on.It's just (4) common sense.

She was the first black woman to earn a Ph.D. from MIT, the first black woman in the country to earn a physics doctorate, and she was both the first African American and the first woman to (1) the U.S. Nuclear Regulatory Commission.Growing up in the late 1950s and early 1960s, when the race for space was in full (2), a young Jackson came to see the world around her as "full of (3) ". For years, she collected bees and kept them under her family's back porch, making (4) records of their behaviors as she adjusted variables like heat, light, and diet. "It was like reading a great mystery novel," she recalls.Her parents encouraged her to pursue her passions, and her siblings, two sisters and a brother, all (5) her natural talents for leadership. But it was the assistant principal at Washington D.C.'s Roosevelt High School who (6) her toward MIT. Today, even at such lofty posts as heading the NRC, Jackson says she is (7) doing the same thing she did way back with the bees: studying interactions in the environment around her, making keen (8), and taking constructive action based on what she learned.Jackson strongly believes that (9) must be "true friends" to one another and assist and encourage one another in their efforts. From her youngest days, she took time to (10) fellow women and minority students in their studies. That's because, says Jackson, being a trailblazer ( 开路先锋) is only a good thing if one does not allow "high weeds" to grow back because no one was (11) to follow. Jackson won't be satisfied to go down in history as the "first black woman" of anything (12) the familiar phrase is followed by two more words: "of many."(1) chair (2) force (3) secrets (4) painstaking (5) recognized (6) steered(7) essentially (8) observations (9) women (10) tutor (11) inspired (12) unlessU7 massive examine similar early observation corrupted stronger probably features sprung source association declared test accidentPeople have long speculated that their languages came from a single source. As (1) as 1767, physician James Parsons collected numbers from many European languages as well as those of Iran and India, and found them to be quite (2). He concluded that they must have all come from one (3). But Sir William Jones, Chief Justice of India, took this (4) a step further. As an educated man, he was trained in the classical languages, so that when he went to India and began to (5) Sanskrit, he saw right away how similar it was to Greek and Latin, not only in vocabulary, but even in grammatical (6). In a speech delivered before Bengal Asiatic Society in 1786, he (7) that the Sanskrit language bears to both Latin and Greek a (8) resemblance both in the roots of verbs and in the forms of grammar than could possibly have been produced by (9). Indeed, the resemblance is so strong, he said, that no scholar could examine them all three without believing them to have (10) from some common source, which, perhaps, no longer exists.(1) early (2) similar (3) source (4) observation (5) examine (6) features (7) declared (8) stronger (9) accident (10) sprung。
