Ⅰ.单句语法填空
1．Part of the reason for that is that these pesticides appear ________(stick) around in the environment and stay dangerous for longer periods of time.
to stick [句意：与这有关的部分原因是这些杀虫剂似乎更长期地存在于环境中并持续具有危险性。appear是连系动词，后接不定式作表语。]
2．________ (receive) your purchases in time, make sure the express company knows your address exactly.
To receive [句意：为了及时收到你购买的物品，要确保快递公司准确地知道你的地址。此处是动词不定式作目的状语。]
3．However，many netizens on Sina Weibo don't think Ele.me is providing a wonderful service，saying it just want ________(make) money.
to make [句意：然而，新浪微博的网民们并不认为饿了么在提供好的服务，说它只是想赚钱。此处是不定式作宾语。]
4．This course is of great interest to students ________ (hope) to improve their writing skills.
hoping [句意：希望能提高写作能力的学生对本课程有极大的兴趣。此处是现在分词作定语。]
5．The young lady, ________ (make) several attempts to fix her cell phone, decided to have another try.
having made [句意：这位年轻的女士试图修好她的手机，尝试好几次后决定再试一次。句中主语“The young lady”和动词“make”之间是主动关系，且该动作发生在主句谓语动词decided之前，故用动词ing形式的完成式作状语。]
6．Nowadays, more and more Chinese homes have the technology and equipment ________ (need) to do online shopping.
needed [句意：目前，越来越多的中国家庭拥有在线购物所需的技术和设备。此处是过去分词作后置定语，故填needed。]
7．Watching basketball games on TV at home is one thing, going to watch them ________ (perform) live is quite another.
being performed [句意：在家里的电视上看篮球比赛是一回事，去看现场比赛又是另外一回事。根据句意可知，“perform”与其逻辑主语“them”之间为动宾关系，由live “现场地”可知，应用现在分词的被动式being performed，作宾语them的补足语。]
8．They discovered that ________(sing) in groups was an essential part in helping people recover from mental illness.
singing [句意：他们发现合唱在帮助精神病人康复方面具有重要作用。此处是非谓语动词作主语。]
