课文再现 这不仅很残忍,并且对环境也有危害。This is not only cruel, but also
harmful to
the environment.

答案

harmful to

解析

“对……有危害”对应的短语是“be harmful to”,句子已有系动词“is”,所以此处填“harmful to”。
迁移运用 1. 医生说果汁对孩子的牙齿有害。The doctor says the fruit juice
is bad for
/ ______ ______ ______
is harmful to
children's teeth.
2. 如果人们不能正确使用核能,它将危害我们的健康和安全。Nuclear power will
be harmful to
our health and safety if people don't use it properly.

答案

1. is bad for / is harmful to
2. be harmful to

解析

1. 对于第一个句子,需要填充的部分是描述果汁对孩子牙齿的影响。根据句意,“对……有害”可以用“be bad for”或“be harmful to”来表达。由于主句是一般现在时,且从句中的主语“the fruit juice”为不可数名词,所以be动词用is。因此,填空处应分别填入“is bad for”或“is harmful to”。
2. 对于第二个句子,需要填充的部分是描述核能如果不能正确使用将会对我们的健康和安全造成的影响。根据句意,“危害”可以用“be harmful to”来表达。由于will后接动词原形,所以直接填入“be harmful to”。
课文再现 为了减轻空气污染,我们应该乘坐公交车或者地铁而不是开车。To
cut down
air pollution, we should take the bus or subway instead of driving.

答案

cut down

解析

本题考查短语“减轻”的英文表达,根据题干可知,此处应填一个动词短语表示“减轻”,且该短语后接名词作宾语。结合所学知识,可知“cut down”意为“削减;减少”,符合题意。

too many trees. (cut)

cut out
smoking to keep healthy. (cut)

the onion then put it into the pot. (cut)
4. The electricity was
cut off
so the room was dark. (cut)

答案

1. cut down; 2. cut out; 3. Cut up; 4. cut off

解析

1. "cut down" 表示“砍伐”,符合“不应该砍伐太多树”的语境。
2. "cut out" 表示“停止,戒掉”,“戒掉吸烟”即“cut out smoking”。
3. "Cut up" 表示“切碎”,祈使句用动词原形开头,“切碎洋葱”为“Cut up the onion”。
4. "cut off" 表示“切断”,此处为被动语态“be cut off”,“电被切断”符合语境。
课文再现 我们承担不起继续等下去而不做行动的风险! We
can't afford to

迁移运用 The company makes beautiful clothes at
reasonable
prices.

根据语境“公司制作漂亮的衣服,价格……”,结合九年级所学词汇,“at reasonable prices”表示“以合理的价格”,符合逻辑。reasonable 为形容词,修饰名词 prices。
Ⅰ根据句意或提示完成句子。

was turned
(turn) off.
2. I always carry a

4. The bad person will bring

has fallen
(fall) by over 20% in the last 20 years.

答案

1. was turned
2. reusable
3. wooden
4. danger
5. has fallen

解析

1. 句子描述的是过去某个时间点的情况,且主语“my phone”是动作的承受者,所以应该用一般过去时的被动语态,即“was turned”。
2. “reuse”是动词,表示“再次使用”,而这里需要一个形容词来修饰名词“cup”,表示“可重复使用的”,所以应该用“reusable”。
3. “wood”是名词,表示“木头”,这里需要一个形容词来修饰名词“table”,表示“木制的”,所以应该用“wooden”。
4. “dangerous”是形容词,表示“危险的”,而这里“bring”后需要接名词作宾语,表示“带来危险”,所以应该用“danger”。
5. 句子中有“in the last 20 years”这一时间状语,表示动作从过去持续到现在,且主语“The number of the sharks”是动作的承受者,所以应该用现在完成时的被动语态,即“has fallen”。

2. 第二空考查instead of的用法,of是介词,后接动词-ing形式,所以选C. buying。
3. 第三空考查one of+名词复数作主语时,谓语动词用单数形式,且根据语境可知是一般现在时,所以选B. is。
4. 第四空考查it's a good way to do sth. 结构,表示“是做某事的好方法”,to后接动词原形,所以选A. recycle。
5. 第五空考查比较级的用法,根据语境可知是回收旧材料比创造新材料使用更少的能源,than后接动词-ing形式,所以选C. creating。
