II.1.amazing 2.facts 3.quarter 4.benefits
5.happening
Ⅲ.1.D句意:我不需要你的帮助。我可以做好。find找
到;call打电话;know知道;need需要。根据I can do
it well..可知,自己可以做好,说明不需要对方的
帮助。
2.B句意:美丽的事物就在我们身边。关注它们,你
会发现生活很美好。about关于;around围绕;from
从;under在…下面。根据Keep an eye on them
and you'll find life is beautiful.可知,注意观察就能发
现生活的美好,说明美好的事物就在我们身边,
around符合语境。
3.D句意:—你为什么喜欢熊猫?—因为它们很
可爱。What什么;Where在哪里;When什么时候;
Why为什么。根据Because they are very lovely.可
知,问的是喜欢熊猫的原因,用Why提问。
4.B句意:《舌尖上的中国》是一部关于中国美食的电
视节目。to到,往;about关于;at在;in在…里。
根据A Bite of China可知,《舌尖上的中国》是关于
中国美食的电视节目。
5.C句意:—什么是“小菜一碟”?—它的意思是
你可以做的一些容易的事情。takes拿;turns转动;
means意思是;loves喜爱。根据What is“a piece of
cake”和something easy for you to do可知,后者解释
了什么是“小菜一碟”,故用means。
6.C句意:萨姆的家庭很穷,他的父亲养活整个家庭。
explores探索;puts放;supports支持,养活;describes
描述。根据Sam's family is very poor.His father...
the whole family.可知,此处指父亲赚钱养家。
7.C句意:一人们都需要知道动植物的重要
性。一是的。没有它们,我们不能生活。survey调
查;difference不同:importance重要性;health健康。
根据We can't live without them.可知,没有动植物我
们不能生存,说明动植物很重要,所以我们应了解动
植物的重要性。
8.B句意:苏珊和朵拉是好朋友。你几乎在任何地方
都能见到她们。elsewhere在别处;everywhere每
个地方;somewhere某地;nowhere没有地方。根据
Susan and Dora are close friends.可知,苏珊和朵拉是
好朋友,所以在任何地方都能见到她们在一起。
V.1.C句意:它们给予我们许多东西,如木材、氧气、橡
胶、药品和许多其他东西。tell告诉;ask询问;give
给予;get得到。根据上文trees are useful及下文
一冲天
such as wood,oxygen..可推知,树木能给予我们很
多东西。
2.D句意:它们还能告诉我们许多关于气候的信息。
not不;too也,常用于句尾;to去;also也。上文提到
树能给予我们许多东西,此处讲树的另一个作用,且
位于实义动词之前,情态动词之后,所以用also。
3.A句意:如果你砍倒一棵树,你可以看到它有很多
年轮。cut down砍伐;climb up爬上;walk past经过;
look at看着。根据下文you can see that it has many
rings可知,把树砍倒能看到年轮。
4.A句意:大多数树每年长一个新的年轮。every每
一个;many很多;the first第一;from从…。根据
常识可知,树每年长一圈年轮。
5.C句意:因为这个原因,我们就可以知道树的年龄。
how big多大;how long多久;how old(年龄)多大;
how much多少。根据上文Most trees grow one new
ring.year.可知,树每年长一圈年轮,所以根据年轮
就可以知道树的年龄。
6.D句意:一棵超过一百岁的树意味着它有一百多个
年轮。trees树;leaves树叶;people人们;rings年轮。
上文提到树一年长一圈年轮,所以一棵一百多年的老
树应有超过一百圈的年轮。
7.D句意:当气候干燥或非常寒冷时,树木不太长,它
们的年轮通常很薄。big大的;thick厚的;small小
的;thin薄的。根据When it is wet and warm,the
rings are much thicker.可知,当天气温暖潮湿时年轮
厚,推知天气寒冷干燥时年轮薄。
8.A句意:如果年轮突然变得很薄或很厚,这就意味
着气候突然变了。changed变化;improved提高;
raised提高;rised上升。上文提到树的年轮的薄厚和
气候有关,由此可以推知,如果树的年轮突然变薄或
变厚,就说明气候突然发生变化了。
9.C句意:如果我们看树的年轮,我们可以了解到气
候。people人们;things东西;climate气候;life生命。
上文提到树的年轮的薄厚和气候有关,所以通过观察
树的年轮就可以判断气候。
10.A句意:我们能知道气候是怎样变化的。上文提
